Projector screen viewing distance
Projector screen viewing distance and incorporating a 1080p projector with your home theater system are two the most important aspects of properly setting up a home theater system. Some enthusiasts are content with just buying any ole home theater projector and screen, hooking it all up and are be perfectly happy with it. But if you are serious about properly setting up your home theater, you will definitely want to find the find your viewing distance use a 1080p projector. With the proper projector screen viewing distance and a 1080p resolution projector, you are going to see detail that you could have never imagined from a front projection home theater system, but making it happen means having the right size projector screen and view distance (subtends) setup correctly.
Calculating your projector screen viewing distance is easy
Using the calculator below you will be able to find the projector screen viewing distance of any given screen size, and seating distance which will allow you to reap the benefits of a higher resolution home theater screen and projector set up.

DIY Projector screen paint
Many enthusiasts will not be too crazy about constructing a built-up home theater screen so most consider projection screen paint as an alternative… With new technology in paint pigment, Now home theater enthusiasts have the option of a paint-on screen over building or purchasing one and Goo systems has the best movie screen paint on the market.
Specifically formulated for home theater projector screen setups, Goo systems projector screen paint contains special pigmented particles that precisely control screen gain and virtually eliminates those glaring hot spots. Goo systems projection screen paint comes in many different flavors of white and or gray. Each shade is specifically designed to control a certain level of contrast and choosing the right shade will entirely depend on the type of movies you mostly watch. But for most, the matte or CRT white will do just fine.
Obviously, home theater projector screen paint is much cheaper than purchasing a production screen. It is however, somewhat competitive in pricing to constructing a built up fabric over wood screen. Here is an article on my home built projection screen… A lot of new enthusiasts will argue that projector screen paint is no different than conventional interior wall paint like you would find at Lowe’s or Home Depot, and would probably not be worth the added expense. Hmmm, let’s discuss that a little…
The latest technology in Home theater projector screen paint has dramatically advanced the formulation… In the past screen paint was actually no different than conventional wall paint, but with the advancement in pigment technology, they are able to create a very competitive product to that of a DIY or a production manufactured home theater screen.
Goo Systems Screen Goo offers a complete line of products, ranging from natural to 100 % pure white, to a barrage of gray shades.
Note: Gray shades will definitely improve contrast on movies that are produced in a darker setting, but in my humble opinion, Matt white is best if you like, a variety of different movie types.
Preparing for and painting a home theater projector screen is relatively easy. Most home theater authorities will tell you to just mask off the selected screen area and start painting by either rolling or spraying it on. However, there is one aspect that I rarely see them mentioning. The wall texture, and how it will affect the image.
In my mind, common sense tells me that flattening down the wall texture before applying the projector screen paint would guarantee a much better subtends (view angle) reflection. Painting straight over wall texture will create an image that reflects light almost at a parallel angle to the screen. Not to mention all the other angles that will reflect away from the audience. This is due to the uneven surface of the texture. This will leave you with an unbelievably poor image quality in comparison to a smooth substrate
I highly recommend masking off your screen area and sanding wall texture completely flat. I suggest starting with 120 grit working your way down to as fine as you possibly can stand then spraying on the screen paint. This will produce a very high quality painted on screen.
Home theater projector screen paint products are definitely more expensive than your conventional wall paints. They actually can cost more than double if you were to build a fabric over wood home theater screen. You’ll have to weigh the pros and cons of building vs. painting a projection screen… One is cheaper, but takes more work and the other is slightly more expensive and is less work. But if you’re weighing towards painting your screen, I would budget for at least $200 depending on which screen paint you go with.

Note: For every 2 liters of screen paint which will sufficiently cover up to 100 inch 16:9 aspect ratio screen.
The Goo Systems CRT White projection screen paint will certainly produce superior image quality over using something form, lets say Lowes or Home Depot brand of white acrylic paint. The Goo Systems screen paint is designed to produce a far clearer and brighter reflection due to the special light reflective pigmented particles in the product.
If you’re still considering using a conventional white acrylic paint, and are not too particular about things, then you’ll probably find that buying a high grade acrylic white paint from Lowe’s or Home Depot may be acceptable. If this works for you, be sure to sand your wall texture flat prior to applying (I highly recommend spraying) your selected screen paint.
Goo Systems projector screen paint:
Goo Systems has a full line of specially formulated projection screen paints, branded as ‘Screen Goo’ that will allow you to use your wall as an effective fixed projection screen! This is by far a superior product home theater use over conventional interior wall paint
This method is perfect for any budget-minded home theater enthusiast. Projection screen paint will allow you to transform a smooth printable substrate into a quality projection screen.
Again, picking the right shade is crucial and completely depends on the style of movies you mostly watch. If you watch a lot of dark shaded movies you’re going to want a gray shade. But, gray shade screens will leave brightly produced movies with a washed out or muddy look as it will effect contrast ratio and vice versa. So pick your screen paint shade carefully.
Something else to keep in mind…Projectors on the less-expensive side generally will have lower light illumines and if used in conjunction with a gray shade screen, most likely you’ll wind up with a low gamma image. For this exact reason I highly recommend going with CRT White or matte white. But if you are still unsure of what shade you should go with, the Goo Systems website has a shade Calculator to help you determine the right projection screen paint shade you should use.
Matching projection screen paint characteristics to your projector can greatly improve the results of image quality in comparison to the more expensive fixed or motorized home theater screens. A DIY painted screen will take a little more effort than hanging up a production manufactured fixed or motorized screen, but overall, this is a great alternative to the ladder.
Bottom Line: In order to achieve maximum results regardless of your projector screen paint of choice, always start with the smoothest substrate as possible otherwise you’ll have a screen that reflects light every direction except towards the audience.

How to build a projector screen
01 year ago
The “DIY” Projector screen
With rising prices of manufactured projector screens, it’s a wonder why so many home theater enthusiasts want to learn how to build their own over shelling out five $500-$1000 for one… On that note, I would like to present you with one way to build a nice home theater screen of your own…
If you’re on a budget and have already shelled out $1,500 or so for your projector, a/v receiver and audio/video cables etc, you’re probably not looking forward to throwing down another $300 to $1,000 for a decent screen that works with your projector’s native aspect ratio. However, there is always the alternative… A paint on screen or perhaps a white sheet?
Shoestring budget projector screen
Many home theater authorities will tell you that you can’t build a projector screen that will perform as well as a professional or production built screen, but common sense will tell you that it completely depends on the materials used, your mechanical abilities to pull it off. The bottom line is if you have more time than money, a “Do-It-yourself” projector screen will probably be your best bet. Again, No offense, but if you don’t have the mechanical skills mentioned above, you’ll probably be better off just buying a production screen otherwise you may end up with something you’re not happy with. But that totally depends on how particular you are..?
On that note, I thought I’d show you how I built my projector screen… It was quite easy to build and the end result was very gratifying. The screen materials were very inexpensive, right around $87, but you should budget $100 to $150 depending on pricing differences between suppliers. I started construction about 10am and was finished roughly by 3pm the same day. So you can count on it taking at least 4 maybe 5 hours to complete depending on how fast you work.
Again, if you’re concerned about your abilities on how to build a projector screen, you’d be better off putting the $100 bucks towards a name band production screen and be done with it over trying to learn how to build a projector screen. Think of it as buying a piece of mind?
Unfortunately as I said above, my screen is already built, but I’ll do my best to explain and show you how it was assembled via pictures below. Before we start, be sure to click on the pictures, they show examples of the construction. They will make the details a little clearer to understand, and also pay attention to the arrows found on the left and or the right over the images because there are more pictures than what you see. Think of it as a manual slide-show… 
build projector screen
Basically, this is a fabric over a two section wood frame (inner and outer frames – inner meaning the screen frame and outer meaning the border frame) home theater screen. It’s held together by “straight”, “L”, “T” brackets and screws. The border (outer frame) is wrapped in black velveteen fabric (no seems or glue – keeping it simple), the screen (inner frame) fits snugly inside of the border (outer frame).
Click on the pictures to see assembly details:
It’s time to start rounding up the materials for your screen. First, you will need to pick up to 1 x 4 Pinewood for the frame you can get at your local Home depot, Lowe’s or any home improvement (lumber) store. You’ll want though wood to be as smooth and straight as possible in order to get a good flat finish. Any rough spots will show up even after they’re covered up. And while you’re there, you should pick up your “L” and straight brackets and some 3/4″ screws as well.
Next, go to your local fabric store and pick up your border covering. I suggest velveteen fabric as it stretches and it is easy to work with. Now, for the screen fabric you’ll need to visit eBay otherwise you’ll wind up paying quite a bit of money for your screen fabric.
Total Cost of Materials:
Velveteen & screen fabric–$43.00
Wood for frame–$26.00
Brackets and screws–$11.00TOTAL: $83.00
Tools you will need to complete your project:
- An Electric jig-saw
- A staple gun with 1/2″ inch staples
- A pair of fabric scissors
- A carpenter square
- A drill with a Philips head screwdriver tip. this will make the job much easier…
- And last but not least, a can of Campbell’s soup
Steps to building your fixed home theater screen:
build projector screen
Step 1:
At this point, you should know what size of screen you’re going to build. You should know precisely the width and the height and if not, you’ll need to know these dimensions before you go any further. Otherwise, you will wind up with the screen that doesn’t match the native aspect ratio of the projector.
Start by cutting the top and bottom sections to the width of your border(not screen). Be sure to include the width of the board X2 over the size of the viewable screen. For instance, if your screen is 100 inches wide, the frame will be 108 inches wide to the outside due to the width of the frame widths which is about 4 inches. Please see pictures.
Cut the left and right sides to length remembering to subtract the width of the top and bottom frames. Take your can of Campbell’s soup and place it on the corners of the top and bottom sections and draw an outline of the edge of the can on all four corners. Using the jigsaw, carefully cut away the corners up to the lines. Something I forgot to mention, you’ll need some 120 grit sandpaper… You’ll need to sand the rounded corners in order to smooth them down after you’ve made your cuts. Using the carpenter square, make sure the structure is square then lineup the top and bottom and the two sides. Take your 4 L brackets and screw the outer frame together. Do not put the fabric on until after you have assembled the inner frame.

Step 2:
With the border(outer frame) assembled, measure and cut the top and bottom sections of the screen (inner frame). Place the top and bottom “screen” sections inside the border then measure and cut the left, right and center sections. Do not make the screen fit too tight otherwise you will not be able to slip the screen inside the border without damaging it.
again, use the L. brackets to screw the left, right, top and bottom sections together and using two straight or “T” brackets for the center. I used four pennies to lift the center section off center to keep it from showing the edges while using your home theater. Please see pictures.
Step 3:
With the frame completely assembled. It is time to cover your outer border. Lay the velveteen fabric out on the floor and then lay the frame face-down on it. Using your staple gun, put one staple in the center of each side, slightly stretching the fabric. Continuing to center the staples as you move around the frame parameter. Do not attempt to staple one whole side at a time because it may cause the fabric to wrinkle. Do the corners last.
Now it’s time to do the inside… Cut through the center of the fabric and then cut a 1/2″ wide strip towards each corner being careful not to cut too close. Otherwise, you’ll see the cut on the outside after you assemble your screen. Please see pictures.
Stapling the inside is a little different than the outside. You can do one side at a time starting in the middle and working your way towards the corners. When stapling the corners, be careful not to pull too hard as you may end up tearing the strip off leaving a hole in the corner. Please see pictures for detailed visual description.
Step 4:
Covering the screen takes a little more care as the screen material tears easy and also could be damaged by the floor, while stapling. First thing you’ll want to do is lay down a blanket and then lay the screen material face down on top of it. Put one staple in the center of each side and work your way towards the corners half ‘ing the distance between the corners and the adjacent stable. Once you reach the corners, you must fold over the corners as you would like wrapping a gift. Once you have stapled all the way around, take a razor blade and trim the excess material from the screen and border.
Step 5:
Now it’s time to assemble the border and screen into one piece. Lay the border down, face-up on your blanket. Take your screen and center it over the border and gently push the screen into the border frame paying close attention not to rip the corners.
Step 6:
You’re almost done… Get yourself some some help and flip the screen over face down on the blanket and secure the two sections together using the straight brackets on all four sides . One straight bracket per side is enough, but feel free to add more. Once you have this done, you’re new “Do it yourself” (DIY) home theater screen is complete!
…And you thought you couldn’t build a projector screen?

Key components to building a media PC – HTPC
2Building a media PC
When building a media PC for your home theater system, it’s very much the same as building a conventional PC, But if you’re not the type that likes to tinkering with technology, then building a media PC may not be the best solution for you. I suggest having a look at production-built htpc’s instead: Moneual 932BD pre-build HTPC
Key components for building a media PC
Here are the key components and what to look for when building a media PC from a standard computer(PC):
Fast processor(s):
Generally, you need at least a fast dual Core processor, preferably 2.0 GHz or faster. although you could use a powerful processor, but you could experience performance issues such as leftover artifacts and or pixel distortion on the screen because the PC can’t keep up with the decoding of the content. This is a must when building a media PC.
RAM: For an HTPC, you need at least 2GB of RAM or more otherwise HTPC will lock up because of insufficient RAM to run the program.
large hard drives: If you’re not planning on saving a lot of video on your HTPC, a 500GB hard drive will do just fine. but, if you plan to use your media PC in conjunction with your personal video recorder, then I would recommend a couple terabyte hard drives. you can get a terabyte drive for under $100 new on eBay.
There are other storage options you should consider when building a media PC such as storing your media over your network such as a NetGear ReadyNAS. there are many manufacturers producing network storage units that are designed to use the Windows media software software.
High-end TV interface, tuner card: A graphics card that has HDMI or component TV outputs is a must have. I prefer ATI and NVIDIA; they offer the best features and benefits for their products for the amount of money you pay. Look for a card with a built-in video processing engine, also known as VPE. These are designed specifically for for video throughput. keep in mind that when building a media PC, you don’t want a gaming card. They are high performers, but they are not designed for motion picture video. You’ll do much better with a card that is actually designed for motion picture video output.
ATI’s “All-in-Wonder” series of cards have a built-in TV tuner which allows for direct cable TV input into the card. Many cards have built-in ATSC tuners that allow high-definition TV channels. and speaking of high-definition TV channels is a great resource for over 1000 of them. this will allow you to get rid of your cable company altogether for a one-time fee of about 40 bucks. You can eliminate your cable service. watch TV online, free forever!
Many HTPC video cards include built in TV tuners that allow you to stroll through TV channels, you may also want to install an additional TV tuner when building a media PC which would allow you to record one channel while watching another. Or record two different channels at the same time.
you can also use your HTPC to record and display HDTV, digital TV but you’ll need an HDTV tuner in order to do so. I would suggest getting an internal HDTV adapter card, but is he did not have an extra PCI slot, then you can get an an external USB HDTV tuner. these types of adapters are readily available on the Internet.
It’s also a good idea to check the supported output resolutions of the adapter that you are considering. If your display device is a non-HDTV unit, you will need no more than a 480i progressive scan output adapter. On the other hand, if you have an LCD or plasma television, it will probably have a native resolution which is a good idea to know before building a media PC in order to match up a video adapter, otherwise your TV will have display issues. So make sure you install a native resolution card can handle your TV’s native resolution.
Building a media PC High quality audio adapter card: Surround sound audio is a must for your HTPC. Audio cards come with many different physical interfaces( output connections), Make sure the one you get is compatible with your receivers, rear interface. For instance, if your receiver has optical inputs, you’ll want your audio adapter card to have an optical output connection. this is also known as S/PDIF interface.
Media drives: you’ll want to completely bypass a DVD player and go straight for the Blu-Ray recorder/player. the Blu-Ray recorder playeris backwards compatible, which will allow you to record CDs, DVDs and or Blu-Ray discs. if for some reason you choose to use a slower processor. You might consider installing a video codec adapter. this component takes the pressure off your CPU and allows it to perform other main processing functions instead of trying to keep up with decoding the video data, while still maintaining primary functionality.
Software needed when building a media PC
The operating system: I highly recommend using either Windows XP or Vista which both have the media Center installed. choosing one of these operating systems will make installation much easier as opposed to other operating systems such as a Mac OS or Linux system.
Building a media PC for playing or recording content: You should also consider software for downloading and storing your music files as well. iTunes is probably the best you’re going to find for music. but, Windows Media Player has no problems taking care of both audio and video files. If you want to use your HTPC to capture your personal video recording, you’re going to need software that will capture the data from your video recorder.
one piece of hardware that most everyone forgets about when building a media PC is a remote control. Many TV tuner/audio adapter cards now come with remote controls as well. Some of these remote controls include software that allow you to control many of the functions of your HTPC so don’t forgot this. Remember to pay close attention when buying your audio video adapters because you’ll definitely want this type of functionality.
beyond this point, your basic computer understanding and “know how” will guide you the rest of the way through building a media PC. on that note, I hope the article answered some of the general questions regarding components and set up.

Fixed Projection Screens:
If you’re planning on using a fixed home theater screen, you will need to be prepared to spend at least $250 -$600 for a decent fixed projection screens
Fixed Frame Projection Screen, 16:9 Aspect Ratio – 165in. (Cine White)
fixed home theater screens can get more expensive that motorized home theater screens… Generally, their construction is designed for a specific application therefore technically more goes into the construction of a fixed screen over the motorized home theater screens. If you have a dedicated room for your home theater, I highly recommend installing a fixed screen over a motorized screen.
Hand-made fixed projection screens
Home theater’s can get very expensive and if you are on a shoestring budget, you may want to consider looking at building your screen. I did and it cost me about $75 for all the Screen Materials. You can buy all the materials from your local hardware and fabric store. If done currently, a hand made home theater screen can easily look and perform as well as any production screen on the market. It all depends on the quality of your workmanship (pride) put into it and of course, the screen materials used create it.
Many people look at this as a daunting task and immediately shy away because generally they have more money than time. If this is you and you have a custom install, I recommend using this free service to find a local reputable contractor that can create and install your home theater screen for you.
Production fixed projection screens
There are many companies producing fixed projection screens and if you choose to just go out and buy one. In some cases you could spend as much on just a screen as one would pay for a high end television! Obviously home theater projection systems can get expensive, but the benefits are much greater now that high definition 1080p home theater projectors are being produced.
.
One thing to think about, if you are going buy a manufactured home theater screen, you may want to look at either a “pull down or motorized projection screen. these types of screens can also get a little pricey, but you can find some great deals out there, you just have to do a little research in the right places.
If you decide that you will go with the fixed home theater screen, be sure to research your available options. You may even be able to pick up a second hand screen by searching online… For instance eBay. Often, you’ll fine amazing deals on used and new home theater screens and other home theater equipment as well.
My first Home theater projection equipment consist of everything except the projector, screen materials(screen fabric purchased from eBay) and cabinet were purchased from eBay. You see, you can find some amazing deals when it comes to buying second hand equipment, you just have to know where to look.
Here are the most popular home theater screen aspect radios to consider. Generally speaking the the wider you want to go, the more you’re going to pay for a projector that can handle the width. Just keep that in mind when you’re choosing your screen native aspect ratio.
On that note, here are the most common screens that are being used many home theater enthusiasts from all around.
