Can a PowerMac 8600/200 run in 1280x1024?

I just picked up a PowerMac 8600/200 with 256MB. https://lowendmac.com/1997/power-mac-8600/ says that the video supports 1280 x 1024 at 8 bits with 2 MB VRAM but I'm unable to get the Monitors control panel to show anything over 1152x870, even when 256 colors or grays is selected.
I'm using a Dell 1905FP monitor which supports 1280x1024.
I've tried two different DB15-to-VGA converters: One with no dip switches, which results in no video at all. The other with 6 dip switches with listings for 8 different modes on the back (21" multimode, 17" multimode, 13" multimode, VGA/SVGA, 21" 1152x870, 19" 1024x768, 16" 832x624, and 13" 640x480). I currently have the first mode selected.
Perhaps I need a different DB15 to VGA converter?

Yes. The 8600/200 can definitely do 1280x1024. This seems to be an adapter issue.

OK, that's good news. Are you running with a DB15-to-VGA adapter? If so, which one?

Could be refresh related, try a CRT monitor if you have one.

I don’t know why your power mac 8600 doesn’t have a PCI video card. Mine came with one. With one of those you’d be all set. No need for adapters.

Try the 17" mode. If that doesn't work, try the VGA mode.
