the desktop is stretched, blurry, too large/small or using the wrong resolution
This symptom concerns the display path. Start with a neutral DeviceOK test where available so the next step is based on evidence rather than a generic reset sequence.
Do not jump to the most invasive fix
Avoid destructive resets, unofficial driver packages, firmware flashing, or replacing hardware before the simpler detection, permission, connection and configuration checks are exhausted.
Retest the same condition
After every meaningful change, repeat the same test under the same conditions and compare the result.
Rule out the simple causes
- 1
Run DeviceOK Screen Resolution Test and note the screen/viewport values.
- 2
Open the OS display settings and choose the resolution marked Recommended where appropriate.
- 3
Check display scaling separately from resolution.
Work through the problem in order
- 1
If the OS offers the expected native/recommended resolution, select it and retest text/sharpness.
- 2
If the expected mode is missing, inspect cable/adapter/dock capability, display identification and the official graphics/display driver path.
- 3
For external displays, verify the selected monitor and refresh rate in Advanced display settings.
A correct OS/native mode with persistent blur shifts attention toward scaling, app rendering, cable/display processing or panel characteristics.
A missing expected mode requires connection/display/GPU capability troubleshooting rather than a browser fix.
