    I have a 8 core 2.8 with the standard Radeon 2600 in it.

    I just got a Dell 24" ultrasharp (widescreen) to go along with my 22" Mitsubishi Diamond Pro 2070SB CRT

    So one is widescreen and one is 4:3 and at first glance the setup works, 1920x1200 on the dell lcd and 1600x1200 on the Mitsu CRT.

    However everything on the Mitsu looks slightly squished. Looking at a perfect circle is the easiest way to tell that something is wrong.

    So in doing some testing, I had a perfect circle up on the CRT and I kept trying different resolutions until the circle looked round. Turns out if I run 1792x1344 or 1400x1050 the circle appears round. Running 1280x1024 looks stretched horizontally as opposed to squished horizontally like 1600x1200.

    This is really weird because all 4 resolutions have the same aspect ratio. Is this some strange bug?

    Actually, 1280x1024 is a 1.25:1 ratio, not quite 4:3 like the rest listed. This resolution will appear like 4:3 on a CRT because they don't use fixed square pixels like most digital displays do.

    Are you mirroring your displays or are they running independent desktops ("extended" mode)?

    Independent desktops, thus the two different resolutions.

    Some CRTs I've used in the past had horizontal and vertical size controls that could be set set and memorized for each resolution or refresh rate. Might want to check how your CRT is set.
