[quote]I've got a Dell 2005FPW, and 1680*1050 is the only 16:10 resolution the Source engine lets me select. It's also the only 16:10 Windows resolution I've got. I'm not sure if one can add 1280*800 manually to this monitor by hacking around on the drivers, it might be possible.
There is an easy way to add your own res when you have a nvidia card. No "hacking" required. Just go to your nvidia display options(rightclick desktop>properties>settings>advanced/rightclick desktop>nvidia display>your screen) and choose the
Screen Resolutions & Refresh Rates and then click
ADD and then type whatever res you want.
All 4:3, 16:9 and 16:10 res you can choose in windows will be availible in cs:s.
I have this same problem as I bought Viewsonic VX2025WM. Only resolution for widescreen in CS:S is 1650x1024 which is native resolution. I tried your solution at the Nvidia control panel but it won't let me add any custom resolutions. It just says "The custom resolution cannot be added." Nice message again from XP...it would be NICE to know why those custom resolutions can't be added ?
