It seems to be an AMD-specific driver issue, but I don't know how to trigger it, so I don't know how to work around it. What does the device manager show for the monitor when that happens? The device manager doesn't list a monitor at all when this occurs, but if I unplug / plug the DVI cable back in the monitor will show up in the device manager within the first few tries and everything will work fine after that (at least until I reboot or wake my PC). I spent some extra time troubleshooting this today with two LCD monitors and both AMD / NVIDIA cards. With the NVIDIA card (8800 GT) everything works fine, I can use CRU to set the custom refresh rates that I want and after rebooting there is no problem with either monitor. With the AMD card (HD 7870) only one monitor works without issue (ViewSonic VP2365wb), but my other older monitor that I wish to use (LG L227WTG) experiences the problem. |
