I bought a Delta PC from you about two weeks ago. I also bought an LG E2250V 22" display.
Every so often the display goes blank whilst I am working or watching a YouTube video. After I tap the keyboard I get a message saying "DVI -D Power Saving Mode". The PC fails to respond to keyboard or mouse and I have to rebout the computer - very annoying!
I have set both Power Saving modes to 'never'.
I have installed the drivers for the LG display.
Any idea what could be wrong?
