Quick Answer

If a stuck pixel appears after a 240Hz monitor upgrade, inspect it within the return or warranty window, then try a pixel-exerciser, since stuck pixels often clear in 15-30 minutes. A new panel with a defect is the retailer's to address. A quality 240Hz monitor at Evetech starts near R6,000, with a dead-pixel policy worth checking at delivery.

Check a New Panel Early

A 240Hz monitor upgrade is the ideal moment to inspect for stuck pixels, while you are inside any return or dead-pixel window. A stuck pixel shows a fixed colour because a subpixel is locked on, and it often revives with pixel-cycling, so you may clear it yourself. If it will not clear, a defect on a brand-new panel is straightforward to claim. The refresh upgrade does not create pixels, but the fresh panel is exactly when to test the whole screen thoroughly.

Post-Upgrade Stuck Pixel Steps

Run a full-screen test on the new 240Hz panel, cycling solid red, green, blue, white, and black to find the stuck pixel's colour, a fixed colour is stuck, all-black is dead. Clean the screen of shipping dust. Then run a pixel-exerciser full-screen over the area for 15-30 minutes at native resolution and 240Hz, repeating a few rounds if needed. Inspect the whole panel, edges included, while the return window is open, and photograph any defect on a solid colour.

If Reviving Fails

If cycling does not clear the stuck pixel on the new monitor, raise it promptly with the retailer, citing the dead-pixel policy and your fresh proof of purchase. New-panel claims are usually the easiest, and a defect found at delivery has the strongest case. Keep your photos and packaging, and act within the return or warranty window so you can swap the panel for a flawless one.

FAQ

Should I test a new 240Hz monitor right away?

Yes. Inspecting immediately after unboxing, while the return window is open, is the best time to catch a stuck pixel. You can often clear it with cycling, and if not, a new-panel claim is the simplest path.

How do I try to fix a stuck pixel on the new panel?

After confirming it is stuck with a colour test, run a pixel-exerciser full-screen over the spot for 15-30 minutes at native resolution and 240Hz. Repeat a few rounds; many stuck subpixels revive this way.

Is a stuck pixel on a new monitor covered?

If it will not clear and behaves as a defect, new panels carry a dead-pixel policy and a defect found at delivery makes the strongest claim. Document it on a solid colour and claim within the return or warranty window.

TIP

Pro Tip

Inspect a new 240Hz panel the day it arrives, run a pixel-exerciser over any stuck spot for 20 minutes, and claim within the return window if it won't clear.
