Some monitors have invalid EDID checksums. Blame the manufacturer.
Windows is more tolerant of EDID checksum errors than Linux is.
If switching monitors solves your problem, then a bona fide EDID checksum
error in the hardware is probably to blame. If you're willing to
build a custom kernel, you may be able to circumvent the problem by applying a
patch. See my kernel-building web page:
In "Step 7: Patch the kernel", there is a specific example of how to apply
this patch. Basically, it allows you to tell the kernel to ignore EDID
check sum errors by using the following setting in a file with the extension
of ".conf" under /etc/modprobe.d:
options drm edid_strict=0
This may allow you to use your faulty monitor anyway. Good luck.
