Matrox Updates DTH2Go for 3x1440x900 and 3x1680x1050

Post by **Paddy the Wak** » 06 Aug 2008, 12:55

He-he ... I do now ... :D

Here is a mock up of GRID ...
I couldn't get the shot with the game running ... the screens came out too dark or too bleached out.

Hi guys ...
Some TripleWide Screenshots here ... http://www.widescreengamingforum.com/node/#comment-

My gaming comp ...

How did you get it working? I followed the instructions exactly and no new 16:10 resolutions are showing up :( Did you encounter any difficulties?

Post by **Paddy the Wak** » 06 Aug 2008, 14:24

Everything went smooth ...
No BIG problems ...
One minor one is that I can't get single screen 1920x1200 to show up in the Display Properties even though I have it as one of my four that we are allowed in the Edit List Mode.

Very odd it hasn't worked for you ...
I see you have a thread ... lets continue this discussion of your issue there ... 8)

May I ask:
(1) Perhaps too early to ask this, but what sort of framerate hit you get when moving from 3 x 1280 x 1024 to 3 x 1680 x 1050 (using your 8800GTXs SLI) ?
(2) When you use single screen mode, does yours come up in the middle screen now? Actually I like to know if this new firmware update includes this 'single screen at center' fix.

I only took note the framerates for GRID ...
I had everything on Ultra High using the Ultra High mod ... running 3840x1024 with 4xmsaa
At 5040x1050 I had to drop back to just the default High setting the game came with and drop to 2xmsaa.
I still lost about 5-10fps ...
I could afford it though as I still get over 40fps.
(I am using a renamed GRID.exe ... dirt.exe such that it uses the dirt profile in the nVidia settings thus enabling SLi as there isn't an SLi profile for GRID.
This vastly improved my framerate)

Single screen mode can be set to any of your screens using a new feature ... "Swap Displays"
You can also switch between various TH and SH resolutions using a hot key of your choosing.

Quick question: does the 57 Hz frequency of the 3 x 1680 x 1050 resolution have any bad effect on LCD monitors? I've never seen 57 Hz as an option in my Display Properties.

Thanks much in advance.

Every 20th frame will will actually be the previous frame (example is a 15z display with an input of 12Hz)
123441234412344 is what a second will look like, you wont notice, the people best able to detect refresh rates will not be able to visually detect any change over 40Hz/FPS.

How is this exactly possible? The max pixels of current GPUs is only 2560 x 1600 = 4096000 but 3 x 1680 x 1050 = 5292000. This exceeds the limit.

I think the screen resolution is limited by the GPU and not the Triplehead2go.

Post by **Paddy the Wak** » 07 Aug 2008, 16:34

As I understand it cards have a limit of max 4096x4096 ...
but then I see this ...

Hello guys ! I just registered when I saw this post.

I've got some 'news' from the Live For Speed forums (http://www.lfsforum.net/showthread.php?p=334212#post334212).

Some guy has discovered that a Nvidia 8800 isn't limited at 4096x4096 but at 8192x8192 texture res. This means that you can use 3 monitors @ 1920x1200 = 5760x1200...

from here .... http://www.widescreengamingforum.com/forum/viewtopic.php?p=83730&highlight=max+limit#83730

and ...

The maximum bandwidth of a Dual-link DVI cable is 7.92 Gbit/s

With 48 bits/pixel:

7.92 Gbit / 60 Hz / 48 = 2.75 megapixels.

With 24 bits/pixel:

7.92 Gbit / 60 Hz / 24 = 5.5 megapixels.

This gives us a maximum resolution of 5.5 megapixels to play with when using 24bits/px.

Seeing as:

5040 x 1050 = 5.292 megapixels,

It fits within (although barely) the 5.5 megapixel limit.

Hopefully this helps clarify it for some people! And if any of it's wrong, I take no responsibility because it's just what I've tried to make sense of from the wikipedia page :)

Check out this thread, especially the conversation I had with JKeefe. I tested my rig and easily ran 5,400,000 pixels on an 8800GTS and DX9.0c. The claim that 9.0c is limited to 4096 horizontal pixels is bogus. The bottleneck is in fact the DVI connection.

Perhaps this data should added to the wiki, since the misinformation seems rampant.

edit
...or see what Paddy said. ;)

Shocking news. It won't be so easy for me to upgrade my three 5:4 panels to widescreen ones, but hey, hurray all the same ! :D

redgun · Post by **redgun** » 07 Aug 2008, 19:22

good news finally. however there is not enough games supporting that res yet, so ill stick to good old 3840x1024. (which is natively support in good games).

next update will be 3 WS projectors :)
:evil: :evil: :evil:

just googled around some, and couldnt find any projector in neither 5:4 nor 16:10. halpz plz. :roll:

Where did you get that from ?

True on an LCD, on a CRT I can still tell when it's 60Hz or lower.

Some times I've been able to tell if it's at 75 or 85hz too, but that's when 2 monitors side by side had one at 75 and the other ar 85hz.

On either though, I don't think anyone could see a difference between 57, 58, 59 or 60hz.

I do know my 23" benq had a 'fix' implemented in it's firmware to drop 1920x1200@60Hz to 58Hz since 60Hz was borderline and causing problems with no images on DVI.

What kind of projector are you looking for, exactly? Specs?

Many brands have native 16:10 projectors, eg Epson EMP-400W, Toshiba TLP-WX2200U, Panasonic PT-LW80NTU, Hitachi CP-WX625.

i don't know a lot about projectors :?. Mostly I'm looking for the right ratio and resolution;

native resolution should be at least 1280x1024 or 1680x1050, which seems to bee the main problem.

image quality should be decent, and price shouldn't be higher than 1000$. If they were low-noise that would be appreciated too, however I'm willing to build my own cooling system :)

Don't confuse limitations of monitors with limitations of GPUs. The highest-resolution computer monitor that is available is 2560x1600 (this is a 30" widescreen). But GPUs can do vastly higher resolutions than this (4096x4096 for 7x00s and below and 8192x8192 for 8x00s and above, to use the nVidia side as an example).
