LG Flatiron monitors.1st one on Dell pc works great. 2nd one in same household to Compaq pc still flashes faint pink on parts that should be white.


Probably just some color balance is of. Reset white to something different on the compaq. Try downloading nvidia-settings and see what happens when you mess with color balances. Mess around with some settings til it looks right, or see if you can reset the white balance to a different preset on the monitor's menu

M2N-MX SE Will Samtron 55V work?


Does not matter the monitor, has to work , probably u test it on a resolution or frecvency that u're display does not support, try to enter safe mode (for windows) by pressing F8 on boot up , and chose than safe mode, or VGA compatible mode, should work! Change the resolution/freqvency to one that u're display supports

If u have more than one video adapters (one onbord) try to see whitch one is enabled....
