Default Re: Nvidia + Matrox TripleHead2Go with resolution 5040x1050!

Hi!

Just for the sake of completeness, here's a summary of Modelines for the most
commonly used display resolutions for TripleHead2Go:

Dual Head Modes
Code:
2x 1680x1050:  ModeLine "3360x1050" 238.00 3360 3424 3488 3680 1050 1053 1061 1080 +HSync +VSync
2x 1600x1200:  ModeLine "3200x1200" 281.40 3200 3264 3456 3752 1200 1201 1206 1250 +HSync +VSync
2x 1920x1080:  ModeLine "3840x1080" 277.00 3840 3904 3968 4160 1080 1083 1092 1111 +HSync +VSync

In combination with nvidia twinview, you can mix those Modelines to form
even higher resolutions (as discussed earlier in this thread), i.e. you could have
a 4x 1920x1200@60Hz quad head setup by connecting two LCD to the first
DVI-D output of a video card via one TH2G and two more LCDs to the second
DVI-D output via another TH2G. Don't forget to use the options "UseEDID" "False",
"ExactModeTimingsDVI" "True" and to provide "HorizSync"/"VertRefresh" as
shown in the sample xorg.conf files above.

Please note that resolutions exceeding 8192 pixel (i.e. 6x 1680x1050 = 10080x1050)
require a recent Quadro card (however, because of lack of material, i couldn't tried that
out, yet).

However, please note that Matrox neither officially supports Linux for TH2G
nor two TH2Gs connected to the same PC at the same time. Also, for some LCDs,
it is necessary to tweak the modelines for proper operation (please check posting
#24 in this thread). So i certainly can't guarantee that such setups will work for you!

regards

Bernhard
