My screen resolution suddenly decreased. I use (legal) win 10 for 3 years, reinstalled about half years ago. Last week my screen suddenly turned to black and then it came back with a lower resolution. Since then I cannot fix it, tried a lot of things.
- Desktop Resolution
Obviously first I've checked the Resolution in the desktop's properties. (The highest one is 1600x1200 and I've set that for comfort but it's scretched).
- Default properties
Then I checked the default properties where I saw (and I don't know if it was different before the problem but I guess) Processor, DAC, Adapter, BIOS details are unknown (Grafics mem/Shared mem: 3967MB,Dedicated/System videomemory: 0MB) in the modes I can't change for a higher resolution because the monitor goes off if I set any higher. The monitor type: Generic PnP Monitor and Microsoft Basic Display Driver.
- Update drivers
Then I've tried to update the adapter (auto detect says it's up to date, I don't know what does adapter mean so I cannot download a driver for it but I've downloaded "driver talent" that couldn't install a ATI Radeon 4000 HD because device was not recognized). Then I've tried to update monitor (up to date, and if I download the most recent driver it is not change anything, ASUS VW223D monitor type).
- Uninstall, disable
In device manager I've tried to disable monitor to force re-recognition but it didn't work. Then I've uninstalled and restarted the computer. It didn't work as well. Then I used Display Driver Uninstaller, PC showed blue screen death then restarted. It couldn't boot so I pulled off everything then back, turned off power took out little battery and the memory cards then back. Then after a couple restart it could boot. Problem was the same but I've waited because I thought it is because of the uninstall, and after 1 hour it worked. Changed the screen to the proper resolution. It took for 10 or 15 minute, then it turned back to the low resolution.
- What's next?
Some info: I have integrated video card, so the graphic specific stuff has always ran slow but it is acceptable for me. I use HDMI sometimes (but now it's not connected, and there's no other screen) I've checked cables, and screen with laptop (by the way it a desktop pc) and other monitor, everything worked well. Windows didn't update (I mean shortly) before the problem. CPU: AMD Athlon II X3 425
So I need solution, I don't want to reinstall windows (my experience it's not permanently problem will come back after a little time) or replace anything in PC. Is there any tips that I could try out?
I found some kind of solution with the GPU overclocking (on GPU with ATI Radeon driver) They suggest to raise the voltage or decrease the CPU clock. I don't want to try it before I'm not sure that It can't make any harm. Is there anybody who had used this solution for some problem?
PS: Sorry for my grammer mistakes!
