Hi folks,

I have dual monitors. One is a 1280x1024 flat panel, and the other is a 1024x768 CRT. Until this morning, I did not realize that I could drive both from my nVidia card. After setting up TwinView, everything works great except for one thing: the CRT sometimes emits a high-pitched whistle/squeal. It is very annoying, and it gets worse when large white areas are displayed. Power-cycling the CRT or smacking it sometimes make the squeal go away temporarily.

This same problem occurred when the CRT was attached to the other video card (an ATI), and I solved it by placing the following modeline in the Monitor section for the CRT:

Modeline "1024x768" 88.50 1024 1088 1200 1376 768 769 772 804 -HSync +Vsync

Now that I only have one Monitor section, I've place the above modeline in there, but the problem persists.

I am using driver version 8776.

Any suggestions would be very welcome. Please let me know what additional information would be helpful. My xorg.conf is attached.

Thanks,

Reid
