Installed a Radeon card, and now monitor is correctly identified as a Dell (1680x1050)
Pull Radeon card and boot with VESA driver, and now monitor incorrectly identified as a Viewsonic, and 1680x1050 not available.
How is VESA driver obtaining EDID info from the monitor? Something is broken.

Found a solution.
Currently I have two PC's connected to a shared monitor with a KVM switch. When I connect the PC's directly to the monitor, then the monitor is correctly identified as a Dell. I also found this post in the forum, which describes the same issue: https://discuss.haiku-os.org/t/force-specific-resolution-in-vesa-driver/3702

That is a pretty good indication that the problem is your KVM switch, not Haiku. I'd say we should close this as invalid; we don't really have any problems reading EDID.

Remove milestone for tickets with status = closed and resolution != fixed
Probably your graphics chipset adds the native resolution in the extra resolutions area. Try a cold reboot.
