DCS A-10C on a 4K Display

[Night]

I am a display-phile and I have been wanting to get an extremely high resolution 4K display for a while now. 4K is basically the same resolution as four normal 1080p displays in a square (two above, two below).

 

Very recently companies have started coming out with 4K displays that will not bankrupt you, such as the $650 Seiko 4K display. Now that they are becoming more affordable, I have been wondering if DCS would even run in 4K? I would appreciate any responses from anyone who has actually used DCS A-10C in 4K, or people with similar setups like using four displays.

I'm trying to imagine the GPU you'd need to run that many pixels. Sounds awesome though.

Triple SLI Titans? :megalol:

Triple SLI Titans? :megalol:

As much as I drool at the prospect of a 4K display driven by triple SLI titans, it might be just a TINY bit out of my budget :D

 

I'm just curious if it would technically even work, if DCS could even support such a resolution.

[Ventus_Clu]

I've seen youtube vids of some setups for DCS using 4 monitors (3 across and one under the centre display) and the framerate looks very reasonable so I'd imagine theres nothing holding DCS back from a 4k resolution, the only issue would be a GPU one because AFAIK DCS only supports the use of a single GPU at a time.

[remon]

Yeah, 4k has about the same number of pixels as some of the eyefinity/surround setups people have been using for years. 4k is 8.3 megapixels, which compared to the 24 megapixels max allowed by eyefinity is nothing, while the typical 1080*3 setup is 6 Mpx. GPU power isn't a problem.

 

And it's Seiki, not Seiko.

You can see some videos of my 4-screen setup here where I'm running 5800*2300 (=13 megapixels) on a single 7970. So yes, its definitely possible.

Sorry, that link didn't take me to one of your youtube videos. Could you please provide a direct link, or your youtube alias?

 

What framerates are you able to achieve with your setup?

 

Thanks!

Sorry, link updated, should work now. I generally get 18-50 FPS, which is good enough for me. And its as good as is possible right now, as there are no faster AMD cards out there yet (my center upper monitor is 3D and only works with AMD, so Nvidia's not an option for me).

[metalnwood]

Yes, as long as it works in windows at the correct resoltuion then DCS will run it fine. On something like the 7970, 680 the frames should be OK as well. Generally, capped at 30 you would acheive that.

Actually no it won't. Remember PeterP posting somewhere that DCS is limited to a max resolution supported by DX9.

 

If i remember right it was something like 8000*8000

 

Found it, see;

Max Ress would be 8192 x 8192

A 4K display (3840x2160) is only about 1/4 of that.

[VTJS17_Fire]

Real 4K is 4096 × 2304 pixels

3840 × 2160 pixels is called "Quad Full High Definition".

 

Next is Ultra HD and was exhibited on IFA 2012 in Berlin.With such a resolution, you don't need 3D anymore, because this ultra high resoultion generates a spatial depth on his own.

My one eyed unkle will be happy to hear this, so that he will be able to enjoy a 3D like vision again.

LOL

 

Do you have a link to this , or did the salesman pass this in verbal conversation to you ?

My apologies.

 

OK.

 

A 4k screen, @4096x2304' is only slightly more than 1/4.

 

 

Btw, how many pixels do you need for 3D to start working? I have several 1080 monitors that I can remove the frames from. ;)

Thats exceptionally witty :laugh:

Nope, I was on IFA 2012 and want to visit the IFA 2013 as well. I could make photos, but my S3 is limited to Full HD, so you couldn't see the ultra HD resoulition. :D

 

IIRC, it was LG with that Ultra HD screen.

Yea Ultra HD is 4k-8k size, basically its the new name that we will be using instead of saying we have HD tv's now, we will be saying we have UHD tv's.

 

Although some japanese firm NHK made a 8k screen and they said its so clear and detailed that it makes 3d useless, they also said that the human eye cant discern anymore detail than roughly 8k, so they think that 8k screens will be the limit.

 

But supposedly the screens are so clear that you can walk right upto them and see incredibly small details.

 

Cant wait for 4k to become mainstream.

First of all, the human's eye resolution can be measured in pixel per angle so to speak, so all those resolution and DPI figures must take into account the viewing distance, otherwise it is of no use.

 

Also, NHK is not some firm, but the japanese national TV station. They will start broadcasting in 8K resolution in 2016 if my memory serves me right.

 

3D is never useless, you cannot achieve depth perception without stereoscopy if an image is displayed on a flat surface. Of course more detail will look more real, but depth perception in terms of displays relies on eye convergency, so you need to show different pictures to each eye so the convergency is different for different objects on screen, creating the illusion of depth.

 

So PeterP got it right - saying real depth perception with just a screen is like saying that a one-eyed person can perceive depth. It is simply not possible due to how the brain processes depth.

 

But I'm really looking forward to an affordable TV with either DisplayPort or HDMI 2.0 inputs, so I can fly in 4k at theoretical 60Hz/FPS (if my system is up to it, which of course it won't be at the moment).

[SkateZilla]

4k is Equivalent to 4x 1080p screens with a smaller Horizonal FoV (Than using Eyefinty 3:1 or 4:1),

 

A Single Titan can do it with reduced GFX Settings and 30 FPS VSYNC

To fix some misconceptions in the thread...

 

• The emerging 4k standard is UHD. It is 3840x2160.
  
• UHD is a standard 16:9 aspect ratio just like 1280x720, 1920x1080, 2560x1440.
  
• There is no difference in FOV of content presented in UHD vs 1080p. Only difference is pixel density.
  
• You don't want the Seiki tv for computing. UHD capped at 30hz via HDMI 1.4a.
  
• You need a DP 1.2 port enabled UHD panel for 60hz 3840x2160 computing.
  
• UHD is a 2x2 grid of 1080p, so it's 4 times the resolution in your current HDTV.
  
• AMD Radeon cards have been able to push this resolution through a single port @ 60hz since the 6000-series implemented DP 1.2 in 2010.
  
• Nvidia Geforce cards have been able to push this resolution through a single port @ 60hz since the 600-series implemented DP 1.2 in 2012.

 

tl;dr: Wait for a cost effective South Korea/China DP 1.2 UHD panel.

And for the ultimate improvement, wait for DCS texture-resolution to increase four times as well.
