Just installed Radeon 9550 and am having problems

[Blue70]

Well I picked up a Radeon 9550 video card.
I installed it and when I try to change the colors, I only have (Highest) 32bit and I can only go up to 1024x768 pixels.
But....When I play Half Life 2 it works great.. What's going on?
PS I am using a Liquidvideo A150x1 screen.

Looking at the specs for your monitor, I think this is the highest resolution that it can support. Maybe in Halflife 2 it's just running at this or a lower res.

Just to be sure, just have a look at

and see if it's the same as your monitor.
