Quick Answer

A monitor stuck at 60Hz after a Gen 5 NVMe SSD change is fixed in software nine times out of ten: open Settings, System, Display, Advanced display and select the higher rate. If 144Hz or 240Hz is missing, the cable or port cannot carry it and needs swapping.

Raise The Rate In Windows

Windows commonly pins a new or re-detected display to 60Hz. Go to Settings, System, Display, Advanced display, and choose your panel's top rate from the dropdown. If the higher numbers simply are not listed, Windows could not negotiate them, which means the signal path, not Windows, is the limit. A new Gen 5 NVMe drive shares PCIe lanes with the top GPU slot on some boards, so an aggressive M.2 setting can drop the graphics slot to a width that confuses the display chain.

Verify The Signal Path Can Carry More

60Hz is the safe fallback every display agrees on, so a cap usually means the link maxed out there. Move to the monitor's DisplayPort input with a certified DisplayPort 1.4 cable, roughly R250 to R450 at Evetech, since DP 1.4 carries 1440p 240Hz while older HDMI 2.0 tops out near 1440p 60Hz. Then open NVIDIA Control Panel or AMD Adrenalin and confirm the rate is set there too, not just in Windows.

TIP

Pro Tip

Test the monitor on its DisplayPort input before blaming the GPU; many 60Hz locks are just an HDMI cable that cannot go faster.

Clear Driver And Profile Locks

If the rate still will not climb, a stale or partial GPU driver can hide modes. Boot into Safe Mode, remove the display driver cleanly, then install the latest stable build and recheck Advanced display. Look in the monitor's own menu for an 'overclock' or 'high refresh' switch that must be on, and reset any saved vendor profile that may be pinning the desktop to 60Hz.

FAQ

Why does my monitor default to 60Hz after a change?

Windows resets a re-detected display to the universally safe 60Hz until you raise it. Setting the higher rate in Advanced display usually fixes it in seconds, with no hardware change needed.

How do I know if my cable is the problem?

If the higher refresh rate is greyed out or missing in Windows, the cable or port is the limit. Swap to a certified DisplayPort 1.4 cable, around R250 at Evetech, and the missing modes usually appear.

Could a driver reinstall bring back my high refresh rate?

Yes. A clean driver removal in Safe Mode followed by the latest stable install often restores refresh modes that a broken or partial driver was hiding.

Break the 60Hz cap with the right cable and a clean driver. Pick up a certified DisplayPort 1.4 cable and a high-refresh monitor from Evetech so your panel runs at the rate you paid for.
