Franc Zabkar squeaks:

I have 15" CRT monitor VISION DX-1564 (~1998), operating at 1024x768.
It supports refresh rate of up to 75Hz at 1024x768 and 60Hz at 1280x1024.

I wish to use 75Hz refresh, but when I put 75Hz refresh rate, the image
has very bright lines.

Do you mean retrace lines?

OK, most likely, I didn't knew the term in English.
