Blurry text because the monitor is using 60i

Select a progressive native timing instead of an interlaced television mode.

Quick diagnosis

An active signal mode ending in interlaced “i” alternates line fields and is inappropriate for crisp desktop text.

Common symptoms

One display has combed motion or soft text while its mode is listed as 60i.
The behavior is repeatable with the same display state.
Changing an unrelated Windows preference does not reliably fix it.

Likely causes

The GPU selected an interlaced timing instead of the monitor’s progressive native mode.
A connection, driver, or configuration boundary affecting the display.
Hardware failure only if the symptom follows the same display across controlled comparisons.

Before changing anything

Record the current display settings and connection path.
Change one variable at a time.
Keep a known-good comparison device, port, mode, or application available.

Diagnose it in this order

1
Create a repeatable baseline
Reproduce the symptom in a simple Windows surface and record exactly when it occurs: One display has combed motion or soft text while its mode is listed as 60i.
2
Run the discriminating test
Inspect Advanced display active signal mode and compare the native progressive 60p/Hz timing.
3
Apply the narrow fix
Select the native resolution under the PC/progressive mode list and the progressive refresh timing.
4
Repeat the original comparison
Keep every unrelated setting fixed and repeat the baseline for longer than the normal failure interval.

Solutions

Blurry text because the monitor is using 60i

Select the native resolution under the PC/progressive mode list and the progressive refresh timing.

Verify the fix

Advanced display should report the native progressive signal and moving text should have no interlace combing.
Restart or reconnect once and repeat the same controlled test.
Confirm the change did not create a new failure in the comparison state.

Roll back safely

• Restore the recorded display settings, connection, driver, or mode if the result is not repeatable.

When to stop and escalate

• If the symptom follows the display across another PC or source after the documented checks, use manufacturer support or warranty service.

Frequently asked questions

Why test before changing several settings?

A one-variable comparison shows whether the proposed mechanism actually controls the symptom and preserves a safe rollback.
