LCD Loses Signal but CRT Find it! Tags: LCD Graphics Cards CRT Monitors Windows 7 Last response: April 4, 2011 1:59 AM in Windows 7 Share BigApeLikeThing April 3, 2011 8:44:21 PM Hi All, Just upgraded my system to Win7 Pro, with new mobo, cpu & ram. During final installation of windows the monitor kept losing signal. If I unplugged LCD from graphics card, and plugged in an old CRT, the picture was there. After a minute I could unplug the CRT and put the LCD back on and it would work. This happens when changing user, booting up (at Window’s login page) and often when installing software. The graphics card was fine in XP, this has only happened since installing Win7, which was yesterday.. I have turned off any sleep and power saving settings in Windows. I have the latest Nvidia drivers for my GTX275.
