Help: ViewSonic VA2012wb

RottenMutt · 01-21-2006, 10:35 PM

hi,
i got a ViewSonic VA2012wb widescreen display (20 inch) and am having troubles getting FC4 to display properly at 1680X1050 resolution without stretching. there is not a display driver for a viewsonic VA2012wb in FC4, so i'm using the generic "LCD Panel 1680x1050" driver which is stretching the display (wrong resolution). My video card is a 6600GT with the latest nvidia drivers 81.78. i have also tried the dell 2005fps driver but no luck. xorg.conf is set for 1680x1050 but it don't work.

I looked at the specs on that monitor. The maximum resolution is 1280 x 1024. It won't go any higher.

thank you for looking but it is 1680x1050 http://www.viewsonic.com/products/de...ries/va2012wb/
windows xp detects it correctly, but no fc4.
i have also tried the dell 2005fps display settings without luck. i am using a kvm switch, could that be the cause?

RottenMutt · 01-22-2006, 09:07 PM

i tried the dvi cable without luck, actually blank screen.

I kind of doubt windows would work with the kvm switch, but not linux. I must have messed up somehow putting your monitor model in the search engine box. That happens, sorry. You might consider making that the only resolution available in linux. Then it pretty much has to do it. I've had where linux was configured to use more than one resolution and it got stuck on a lower one. The only solution was to remove the other resolutions. That forced it to the higher resolution.

i've found a link to a dell 2405fps where the solution was to add modeline entries:
http://www.linuxquestions.org/questi...ight=2405+dell
i think this is the solution, now to figure the correct modeline. here is a link to a modeline generator http://xtiming.sourceforge.net/cgi-bin/xtiming.pl

here is a simillar link, crosslink, to a dell 2005fps where a user is having a simillar problem:
http://www.linuxquestions.org/questi...d.php?t=406540
should be a same solution.

i'm using a four port kvm switch which works fine with the two other WinXP boxes.

set 1680x1050 screen resolution, by select desktop-preference-screen resolution 1680x1050 fixes it.

FC4 has a "gtf" program which will generate modelines, and it is to the general timing formulas which is what i used. i did notice that most of the online modeline generators do not agree with the general timing formulas, so be careful. i got a spreadsheet from Viewsonic who go it from NSC, I moded it to create the linux modeline.

i do like that you can set any refresh rate and or resolution you want, unlike windows which is only what is available. i need to add modelines for the popular resolution formals for games, but if the game doesn't get good frame rates at the native resolution i will just use half the native resolution (840x525). in other words four pixels will make up what 1 did.
