1080p Dead Pixel Test

Click Full Screen and scan each color. At 1080p, individual pixels are large enough to spot easily from your normal viewing distance — a single dead pixel is hard to miss once you scan systematically.

Testing a 1080p Monitor for Dead Pixels

Full HD (1920 × 1080) packs 2.07 million pixels — four times fewer than 4K. At 24 inches, pixel density is 91 PPI and each pixel measures 0.28 mm across. From a normal 50–70 cm viewing distance, a dead pixel on a 1080p monitor is clearly visible to the naked eye. You do not need to lean in close or test at maximum brightness — though both help you catch faint stuck pixels.

Go full screen and work through the colors in order: black first (reveals bright stuck pixels), then white (reveals dark dead pixels), then red, green, and blue to expose sub-pixel faults. Gray is useful for catching pixels that appear correct at full saturation but fail at mid-brightness. Spend five seconds on each color, scanning in horizontal strips from top to bottom.

What to Do If You Find a Dead Pixel

If the pixel is stuck on a color rather than fully dark, try the stuck pixel fix tool for 10–20 minutes. Most 1080p monitors use TN or IPS LCD panels, which respond better to rapid color cycling than OLED. If the fix fails or the pixel is permanently dark, check your warranty status and contact the manufacturer. For a step-by-step guide to making a claim, see the dead pixel warranty guide.

1080p Dead Pixel FAQ

How visible is a dead pixel on a 1080p monitor?+
Very visible compared to higher resolutions. A 24-inch 1080p panel has 91 PPI — each pixel is 0.28 mm wide. At a 60 cm viewing distance this is clearly distinguishable by the naked eye. A single dead pixel on a 1080p monitor is hard to miss once you know where it is.
Will a manufacturer replace a 1080p monitor for one dead pixel?+
Unlikely under standard warranty. ISO 13406-2 Class II permits approximately 4 bright and 4 dark defects on a 2.07 MP 1080p panel. In practice, a single dead pixel near the centre is worth reporting within 30 days — retailers are more flexible than manufacturer warranty channels.
Can I fix a dead pixel on my 1080p gaming monitor?+
Stuck pixels (glowing a fixed color) sometimes respond to rapid color cycling. Open our fix tool and run it for 10–20 minutes. Truly dead pixels (permanently dark) cannot be fixed in software. 1080p gaming monitors typically use TN or IPS panels, both of which respond better to the cycling method than OLED.
Is it worth upgrading from 1080p if I have a dead pixel?+
Dead pixels are equally possible at any resolution. If your 1080p panel is within warranty, pursue a repair or replacement before spending money on an upgrade. If it is out of warranty, a dead pixel on a 1080p monitor at arm's length is more noticeable than on a 1440p or 4K panel at the same size — it may be a reasonable motivation to upgrade.
