"Use Centered Timing" in Catalyst Control Center Does Not Work on Certain Resolutions
In other words it doesn't work for _all_ 4:3 resolutions.
I see this topic several years old... Was it ever working ? Is there any solution for ATI users besides changing video card to nvidea ?
It's taken me a couple of days, but I've got it working. I think it could be fixed by using the official Catalyst drivers of at least version 8.4, instead of using the Omega drivers, but to be sure it's not something minor I'll include all the steps I've taken.
I'm using a Samsung 205BW connected by DVI to an ATI X1900XTX.
3 weeks ago: A new install of WinXP Pro, install Omega 8.4, monitor is detected as plug and play (works fine).
2 weeks ago: Windows Update overwrites Omega with some generic basic drivers. Reinstall Omega 8.4
Yesterday, spend a few hours on this forum, fiddle with Display Properties - Settings - Advanced. Omega drivers include plenty of options, changing the display settings to 'not scale' does nothing, 'maintain aspect ratio' is ignored. There are similar options in the ATI tray tool installed with Omega, but again these do nothing.
At this point it is impossible to get a 4:3 ratio / black bars at the left and right of my screen.
Today: Install PowerStrip, it's a fairly complex program, but fiddling with many settings I manage to get a 4:3 ratio, but only at odd resolutions (1400*1050), any old games automatically shift to popular resolutions (1024*768) which streches the screen. I try for a couple of hours, but cannot get a 4:3 aspect ratio at popular resolutions.
Install monitor drivers, it's a 100kb file and seems to just change the name of my monitor from plug and play to SyncMaster 205BW. I retest the previous steps, but the monitor drivers seem to change nothing.
I uninstall PowerStrip and the Omega drivers, and download the official ATI drivers with the bloated Catalyst Control Center, afterwards install .NET 3.5.
Start Catalyst - Advanced, Digital Panel - Attributes - Image Scaling, and it all works perfectly.
I can get a 1024*768 with huge black bars on all 4 sides, or have it streched and get small black bars at the left / right.
