can't rotate desktop 90 degrees, but 180 works

[anders thoresson]

Hi,

I've just installed a Sapphire Radeon 9100 in my computer, to with a
Samsung Syncmaster 171s TFT-monitor is connected. The monitor is on a pivot
stand, but I haven't installed the pivot software yet. I just found out
that my new graphic card can do screen rotating by itself. But when I try
to rotate my desktop 90 degrees, I get an error telling me that at my
current settings the screen can't be rotated. Rotating 180 degrees works
fine though.

I'm on a Win2k-computer, SP4 and using ATI driver 6.13.10.6218.

Is this a known problem?

It might have to do with the resolution you have set your LCD to. Just a
guess, but you might wanna try another resolution and see if it works.

If I go down to 1024x768 from 1280x1024, I can rotate the screen 90
degrees. But on 1280x1024 I get the message saying that rotation can't be
done at with the current settings.

Why not? My monitor's native resolution is 1280x1024 and it shouldn't
matter wether I want to use it for 1280x1024 or 1024x1280?

I get the same response, I assum that the 1280 resolution cannot then be
displayed horizontally, I drop the resolution then rotate the screen on the
PC, then physically, then up the resolution......

Are you doing like this: 1280x1024 -> enter 1024x768 -> rotate 90 degrees
to 768x1024 -> change resolution to 1024x1280?
