Windows 7: Running 2 Monitors, 1 or both will randomly start up inverted colors

07 Apr 2015   #1

Running 2 Monitors, 1 or both will randomly start up inverted colors

After lots of fiddling and frustration I have decided to give this a shot. I run 2 x Hanns-G HE245DPB LCD monitors, and often they start up with one or both of them having the colors inverted.

Sometimes a restart fixes this, and sometimes it doesn't. I have tried turning them on after my computer has started, turning on the secondary monitor after login, checking the connections... and it keeps happening. I have a fair amount of experience troubleshooting computer issues, and I haven't really seen anything like this before. If anyone has experienced this before I would GREATLY appreciate input!

Hi welcome to the forum

have you tested the monitors on another computer? this would tell if its the monitors or the computer. have you tried updating the graphics drivers? does it happen when just one monitor is hooked up?

edit: have you tried the intagrated graphics?

sounds like graphic issues... Did you have updated drivers?... did you change any settings for display?

Windows 7
Same problem

I have the exact same problem with the same monitors. However it is only my 2nd monitor that has inverted colours every day I start up my computer. The only temporary fix is to remove the DVI cable and plug it back in until the colour as back to normal. The other monitor is connected through a VGA cable with a DVI adapter. I have just recently updated the graphics driver. I am yet to try another DVI cable and see if the monitor drivers need updating. However it is only in one screen.

I have faced this problem with "second monitor" (Samsung TV connected through HDMI) on Win7 64bit (videocard ASUS 5770 1Gb DDR5).
Unplug/plug HDMI cable (or switch mode extend/dublicate) brings situation to normal but not longer than for 15 minutes (extremely annoying).
Inversion never seen on primary monitor (DVI-connected).
Any ideas on how to fix this?

Dual monitors aren't showing the same colors/display
So I recently got a second monitor so I can work with two screens at once. As I kind of expected, I had to calibrate the monitors so their colors, brightness and all everything else match each other. But how much I may try, I can't manage to calibrate them properly. Worse, both monitors seem to be...

Theme Colors in Explorer/Start Menu
So, I'm trying to install a theme (charleston2378's deviantART gallery) for my computer, and I think I'm mostly there. I've replaced all of the .dll files and applied the theme in the Personalization window. The only thing left is my Explorer and my Start Menu. It's supposed to look like the first,...
Identical Monitors, not identical colors
I received my 2 Samsung BX2431 LED monitors today, hooked them up, installed drivers. And now after wasting an hour on finding out that I had to do scaling on my card in the AMD Vision control center to get rid of the black bands, I still am left with the problem that one monitor is whiter than...

Running two monitors?
How can I run two monitors from one computer? Can I run a VGA and DVI from the motherboard into one video card which has VGA and DMI? Or do I need a dual VGA card?
