I have had this flickering issue ever since I updated to windows 10 2 years ago. My laptop is Lenovo y50-70.
I have updated the graphics card (and every other driver). Updated the BIOS. Played with the VGA intel driver settings (suggested by someone online). I dont have the "Panel Self-Refresh setting" option visible in my intel VGA settings, and my BIOS is already at 3.03 (Latest).
I also did the cpu processing throttle to 99% , and several other values like 1% , 5%, 70%, 100%, without success. Basically every suggestion found here in any online furom.
All of that and more and still the issue doesnt go away.
When it becomes so bad I open the laptop and deattach/attach the screen cable. This resolves the issue for a couple of days and it comes back even worse every time.
Although this may suggest it is a hardware issue, it never happened before the win10 upgrade. It also seems to happen more severly when certain websites are open, and also when certain programs are used. Check this video I uploaded to know what I mean.
A few months ago the problem suddenly was complicated and the screen went corrupt (green haze with white lines). I had to buy a new screen and install it. Things seemed fine after that for a month, and it is now back again flickering!
I have a separate monitor connected by HDMI to the laptop and it works fine (thus it is not a VGA issue)
I am frustrated and tired. I payed top-dollar (back then) for a laptop that acts as a workstation/gaming platform and this flickering is killing me (along with the heat in left side of keyboard during gaming, but ppl online says it is normal so I dont mind)
probably just coincidental with the upgrade, but to me looks like a bad cable connection. now since you wiggle the screen and it happens make me think you have an intermittent cable probably where the cable passes through the bottom deck to the screen beside a hinge. myself I would replace that entire video cable.
I have a feeling it would boil down to this cable as well, but the thing is some applications seem to have a severe effect (in the video I open my computer and the screen is unusable, but when I close it or move it to the adjacent screen the screen returns back)
Does this not indicate a "soft" issue instead of a "hard" one?
