It should work. I don't know why it wouldn't. Maybe the timings it chose for you aren't compatible.
Try these manual timings:
Horizontal front porch: 48
Active horizontal pixels: 1680
Horizontal total: 1840
Horizontal sync width: 32
Horizontal sync polarity: -
Vertical front porch: 3
Active vertical lines: 1050
Vertical total: 1087
Vertical sync width: 6
Vertical sync polarity: +
Then set the desired refresh rate to 75 Hz.
It will actually accept up to 76.647 Hz using those timings. Going any higher causes it to intermittently reject the resolution, so don't go above that. The monitor will report 77 Hz since it rounds up.
