2013 Gaming Screen Build

Document the build progress for your screen or computer setup.

The screen was supplied by Stewart Filmscreen. It's an interesting design. As the screen bows with tension, the access door also had to be constructed with the same curvature. The material is specifically designed for image blending so looks pretty stunning in action!

Hello, was wondering if you ever came up with a recap - summary of your last build so we could get inspiration from? Thanks.

Yep, looking at the method I should use to release the information. In a formatted PDF book, a YouTube video or maybe a webpage? Right now we're in the the process of redesigning the whole website to be more functional. New main page, new sales page, new FAQ/How-To pages and potentially a games database and a user setups database section. This could potentially go under the FAQ/How-To area for content. there are a lot of things I'd love to improve on my 2013 screen, but I think it would be good just to get the design out there so others can use it as is. It's not 100% ideal, but it works for my needs and is a starting point for improvement for new builds.

Oh WOW! THIS Looks AWESOME!!!
Very nice work, I might have to re-do my screen and go bigger like you!
I just need to convince my lovely wife and of course that pesky thing money, need some of that as well.

At issue when you go taller screen the pixels get bigger. It's one thing I don't like about my 2013 screen with 800p projectors. I've always recommended no taller than 60" with 1280x800 projectors. It would be more preferable with 48" screen projection height. Pixel density is better and 48" is rather standard for lumber so less long seems to mud and finish. I know some sheeting can be ordered in 144" x 48". I'm thinking on experimenting with a sheet to see how it looks.

Yeah I didn't think about the pixel's getting stretched too much.
Still looks amazing though!
Good thing I'm now broke any way. LOL.

So I would like to build one of these and make it a wider resolution for a better horizontal FOV setup. Is this possible and what would I need? Was thinking about something to the effect of 32:9 or maybe a hair less and just doing 120 degree FOV. That way I'd get a good setup w/less fisheye that comes w/some games and it would drop my price considerably. How do you determine refresh rate on a projector and do you have any that would use DVI-D Dual link or DP 1.2 Cables for better frame rates? Currently I run (a bit over the top) 6400X1080 on monitors w/120+ fps at all times w/maxed settings on every game. I want something more immersive but don't want to break 2500$ mark on the screen/Projectors.

I should be able to better answer things over the weekend. I'll bookmark this post so I can get back to it in detail tomorrow. I have answers for all the questions, but a few of them will take a bit of time to write up.

The idea is a "budget" build. I don't want to break $2k but I want 120 degrees w/120+fps and 32:9 resolution. Might be tricky. Currently my Setup is nice w/monitors at 53:9 but I wanted bigger/more immersive and a way to cut out the fisheye.

Do you have a preference of 1080p or 800p resolution on the projectors? I'm a real fan of the Optoma GT1080 and the Benq W1080ST. The projectors will be a bulk of the build budget but it's important to get quality.

Eyefinity 2x1 or Nvidia Surround 2x1 32:9 or 32:10 would work fine at 120 degrees. Would probably make for both a decent gaming/sim and home theater configuration. You'll still get a bit of barrel distortion/fisheye with 32:9 but it's not pronounced as triple projector. It's just an inherent weakness in game camera code that is designed for 5:4 to 16:9 rendering.

On refresh rate, I go with the fastest refresh rate the projector can handle at it's native resolution. If that is 120hz on a 1280x800 projector or 72hz on a 1920x1080 projector, it's really up to the specifications of the projector you pick. I don't know of any 1080p projectors that are 120hz native capable though.

Cables are only as capable as their weakest link in the pipeline. Most projectors are HDMI 1.4, which is essentially DVI Single-Link bandwidth sized. If you can get projectors with DisplayPort native on the back of the projector and use the DisplayPort on your video card that'll be the widest bandwidth possible, but DP projectors are very rare - Especially rare with short throw lens requirements of 0.49:1 to 0.82:1 range. You don't want to be using port display adapters unless you have no other choice. It's best to keep to the fastest port type you have on both the projector and the video card with no conversion in between. That being said, even then projectors have a maximum hz speed limitation built into the DLP processing chip. It's a trade off between 120hz 1280x800 and 60 to 70hz range 1920x1080 projectors. You can have higher hz or higher resolution but not both. It's just a limitation of what is available on the market right now.

Off on a bit of a tangent but looking towards the future -- In an ideal world we'd have an LED-laser hybrid projector that has long bulb life which runs cool temperatures, it would be 0.49:1 short throw lens to ensure a big picture in a short projection distance, 120hz 1080p native DLP chip and it being fed by a DisplayPort 1.3 native port on the back of the projector. That would be the holy grail of projectors for simulator setups. It doesn't exist in any single projector yet though most of the individual specifications are on various projectors out there individually. Food for thought.
