I have wired RGBEHV to a VGA, tied H and S togeher. I am using a Radeon 9200SE via WinXP. Soft15 helped me output 25kHZ, per my crt manual instruction. Default video card driver has 640x480 32bit available and works well. The result is just the top part of the screen cannot be seen, which make sense based on the crt manual noting 640x350.
My board has a vertical position trim pot, but it doesn't seem to do anything at all - even when I short the pot legs hoping the screen will jump. The vertical size trim does work though. I used Catalyst to shift the screen, hoping I could change the size and shift, but it just isn't enough to fix my problem of the top part of the screen being cutoff.
I have made several attempts at changing the resolution: qres, 12noon, and a few others. I had success with PowerStrip to get 640x350; however, the monitor will not sync in this resolution. It may not be the resolution, necessarily. Leading up to this point, I started seeing the monitor go out of sync at computer start-up. I would need to power the crt off and the back on to sync - has been a good solution; started about the time I really refined the image by adjusting B+.
All of this leads me here now at your mercy. First time posting. Based on above, I have the following questions:
1. Is there another crt adjustment that I am missing for the vertical position?
2. Any idea why I now have to power cycle the monitor to sync?
3. If I get sync with 640x350, I wonder if that will even help the vertical position problem. Other ideas to solve my clipping at the top of the screen?
4. Will pictures help you guess with me?
