How to Fix Lag Spikes on a Mechanical Keyboard
Lag spikes on a mechanical keyboard often have a fixable cause. Separate accessory latency from network, driver, display, and system causes before blaming the device or buying a replacement.

A stuck pixel on a RTX 5070 build build is still a screen issue first. Test solid colours, the monitor menu, another cable, and another output before blaming the build component. If the dot stays fixed on the same panel area, collect evidence for the display rather than replacing working PC parts.
A stuck pixel normally stays one colour while the rest of the panel changes. Test red, green, blue, black, and white at native resolution, then open the monitor menu over the same area. If the coloured dot appears in the menu, the panel is the target; if it moves in screenshots, check cable or driver output.
If the mark is a stuck colour rather than a black dead pixel, try the monitor pixel refresh, panel refresh, or a short moving-colour test. Keep the session reasonable and stop if the panel becomes warm or uncomfortable to watch. Do not press hard on laptop, OLED, or handheld screens.
Use a reference such as GeForce RTX 5070 build and test desktop UI plus a game menu. A 1440p 144Hz or 165Hz monitor should show crisp UI text, while 1080p stretched to 1440p can look soft. High-end GPU builds may run esports titles above 144 fps, but a panel pixel remains fixed when FPS changes. Broad SA PC baskets can run from R8,000 to R35,000+. Evetech listings can help later, but first separate panel fault, cable issue, Windows scaling, and monitor setting. Keep one full-screen photo, one close-up, the resolution, refresh rate, and whether the mark appears in the monitor menu.
For SA support, keep the invoice, serial number, and photos in normal room light. Match the result to the symptom: fixed black dot, stuck coloured dot, soft text, flicker, or cable artifact.
No. A stuck pixel is normally panel behaviour, not a direct fault from the RTX 5070 build. Treat the named device as context unless the display output path changes the result.
Sometimes a stuck sub-pixel recovers after a panel refresh or moving-colour test. A dead black pixel is less likely to recover, so document the difference first.
Use photos on solid colours, the monitor model, serial number, purchase proof, refresh rate, and cable type. Clear evidence reduces repeat testing during support.
Use pixel refresh only after colour tests prove the mark is stuck; if it remains, keep photos and model details ready for support.
