You can trying playing with "modelines" where you reduce the screen refresh rate to 30Hz to keep the "dot frequency" below the card's limit. Contrary to CRT, current displays tend not to need as high a refresh rate to avoid flicker. Of course a lower refresh rate may encounter other problems (e.g. your display may simply refuse to display it). Stefan

I believe that the DAC on the G550 is only good up to 2048x1536 (DVI) or 1600x1200 (VGA). It was pretty good when it was introduced 20 years ago, and not too bad when the PCIe version was made 15 years ago. -dsr-

If your HP G200e is working, then so should Chris' be able to as well. The G200e is a special evolution of the original G200/G400/G450/G550/G650 series that last I knew was no longer supported upstream since KMS matured. AFAIK, the G200e was supposedly the only chip supported by MGA X driver patches intended to keep X viable on HP servers without anyone willing to provide kernel support for KMS on Matrox. I do have the MGA driver xserver-xorg-video-mga dysfunctional on (an AGP) G550 in i686 Bullseye by disabling KMS via nomodeset on, and adding iomem=relaxed to, the kernel command line, without installing firmware-misc-nonfree. The dysfunction is the screen blanks momentarily at random times, but is otherwise normal as long as xrandr is not needed to configure the screen. Installing firmware-misc-nonfree doesn't help. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!
