recently I've bought a new 23" HP Compaq LA2306x monitor for my Lenovo Y50-70 laptop. Connected it via HDMI (from laptop) to DVI (monitor) cable and at first it seemed to worked flawlessly from the very beginning. And still works, until I run a game. I've tried playing Dishonored, which works flawlessly at highest resolution and medium/high graphic quality settings on my laptop, but after about 15 minutes the screen went completely black for about a second or two, and then turned back to normal. As if the power cable was plugged out for a second. After that it happens more and more often until the game is practically unplayable. In Portal 2 it doesn't seem to happen so often, but still does. When I browse the web, watch movies etc. everything works perfectly.


My laptop is getting warm after playing, but since I have a cooling pad under him, and it never caused any screen freezes or framerate drops, while using my laptop's screen it was never a problem to me. I play at the exact same graphic settings as before. Is it because of the overheating? The graphic card is too weak? Problem with a cable?


My specs:

nVidia GeForce GTX 860M

Intel Core i7-4710HQ @ 2.50 GHz

Monitor's refresh rate: 60 Hz

The monitor is overheating and the power supply is resetting itself.  Obviously the game play is too much and it goes into cascade where it happens more and more frequently.  If it's beyond warranty, try mounting a small fan to cool the unit.  Locate vents to insure they are clear and clean,  I have used hot glue to mount small fans in vents to help cool small CRTs it should work for the small LCD/LED monitors.
