Performance hit when rotating your monitor... - Tilted Forum Project - TFP - Sexuality, Philosophy and Political Discussion

I just got a new computer at work and a pair of LCD monitors. Now, because it's a dual monitor system, I thought I'd use each of them vertically and make a virtual 3:2 screen with them, to best approximate an ordinary 4:3 screen.

However, now that I have done so I can't help but feel that things seem to redraw a little slow and I suspect that I'm taking a performance hit by having the video card rotate everything by 90°.

So, does anyone know anything about video cards and their DVI output? Is there really a performance penality for rotating my screen? Has anyone else experienced anything like this?
Thank you...

I tried it, I didn't see much differences in performance honestly. What video card and cpu speed do you use?

I'm using an NVIDIA Quadro PCI-E DVI video card with a P4 3.4 GHz HT processor. Actually, I'm now using both orientations (primary 4:3 and secondary 3:4) and I'm certain there is a performance penalty. There is no reasonable explanation for this phenomena that I can think of except a poor hack of an implementation...

Are you sure you haven't noticed any difference? Are you running at 1600x1200 resolution?
