samsung's website has windows drivers for that monitor, I would download them and install them and see if that fixes his problem.

Is there a monitor shut down period?

If not in the OS then on the monitor itself?

Highly doubt its driver related.

 I didn't know that monitors had drivers. I installed the drivers and it didn't seem to make a difference. thank you for the help though :)

the monitor just suddenly goes blank. the monitor seems to be working fine, it's just no longer receiving a signal from the computer through the hdmi cable. we've tried different hdmi cables, but that doesn't fix it. the monitor only has hdmi and vga, and the GPU has hdmi and dvi, so trying a different connection isn't an option.


it genuinely seems like the GPU stops sending signals.
