Troubleshooting
Problem: The desired resolution isn’t listed.
Solution: Update the GPU driver and monitor driver; the correct driver exposes all supported modes.
Problem: Screen looks blurry.
Solution: Set the native/Recommended resolution and match the scaling under Display settings.
Problem: Screen went black after changing.
Solution: Wait 15 seconds — Windows reverts automatically if you don’t confirm; or boot into Safe Mode to reset.
Problem: Resolution resets after reboot.
Solution: A driver or dual-GPU conflict may override it; update drivers and set resolution in the GPU control panel too.
Conclusion
Changing resolution is easiest through Settings > System > Display, where the Recommended value gives the sharpest image. For quick switching, command-line tools like QRes or a hotkey utility offer fast alternatives.
