No signal to monitor after underscan correction

I’ve recently corrected an underscan problem using the reg hack detailed here:


I did this when I got a new 1080p monitor/TV  and it worked fine, but the problem reappeared after installing the latest version of Win 10. The reg hack still works to solve the underscan, but when I start the machine, the monitor no longer picks up the signal. My older 4:3 monitor, which use as a second screen, still works ok though.


As the 1080p monitor/TV is my primary screen, I really need to fix this. Strangely, if I reboot, the screen will work, but not from a cold start.

Hope someone can help.


My system:

Dell Vostro 430

I7 860

ATi Radion 4300

8gb Ram

Samsung SSD 840


Primary Monitor: LG Flatron M2280D Monitor TV

Secondary Monitor: Dell 1024x768
