If you see the “No 144hz” symptom, candidate causes include cable bandwidth limitations, resolution/refresh rate combination limitations, etc. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
Solving Order
We've organized the methods starting with the simplest and least expensive ones. Please check the solutions one by one, starting from the top.
Please check them in order from the top. If the issue is resolved, you do not need to proceed to the next step.
You can correct incorrect resolution, refresh rate, HDR, and expansion settings.
confirmation point
After these steps, see if the “No 144hz” symptom decreases or disappears. If there is no change, check for possible cable bandwidth limitations in the next step.
High resolution and high refresh rates are limited by cable and port bandwidth.
Outdated or corrupted graphics drivers can cause the symptom.
The combination of variable refresh rate, HDR, and overlay may create flickering or transition issues in certain environments.
This is the most reliable way to isolate whether the problem is with the PC or the monitor.
We've put together a list of things we frequently check regarding this issue.
If the symptoms do not match exactly, please check the issue below.
If you see the “Resolution not selected” symptom, possible causes include not installing graphics drivers, cable/adapter restrictions, etc. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
If the symptom of “one side of the dual monitor is not working” appears, possible causes include cable/port problems, display mode settings, etc. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
When troubleshooting a screen that keeps flickering or flashing, it is important to rule out the causes one at a time. Based on the “screen flickering” symptom, check for graphics driver, refresh rate, or cable issues before proceeding to the next step. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
If “screen tearing” repeats, it is better to narrow the scope to frame and refresh rate synchronization issues and V-Sync/VRR setting issues rather than changing several settings at once. Resolution, refresh rate, HDR, VRR and cable bandwidth must be checked together to distinguish between setup issues and hardware limitations.
