IPS Glow vs. Backlight Bleed: How to Tell the Difference
The definitive angular viewing test to distinguish inherent IPS technology traits from hardware defects.
1. The 30-Second Head Movement Test
1. Set the room lights low and open the ScreenCheck Backlight Bleed Test on full black.
2. Look at the bright corners of your monitor.
3. Slowly move your head from left to right, or stand up and look down at the display.
• If the glow changes color (often shimmering between gold, silver, or purple) and disappears or moves as your angle changes, it is IPS GLOW.
• If the bright patch stays locked in the exact same spot along the frame edge regardless of your head position, it is BACKLIGHT BLEED.
2. Practical Ways to Minimize IPS Glow
• Sit further away: On large 27" and 32" screens, the corners sit at sharper angles to your eyes. Sitting an extra 15–20 cm back dramatically reduces perceived corner glow.
• Lower your brightness: Standard office displays are often shipped at 100% brightness (350+ nits). Reducing brightness to 30–40% (around 120 nits) dramatically diminishes glow without sacrificing color.
• Use bias lighting: Placing a neutral 6500K LED strip behind your monitor raises ambient pupil contrast and makes corner glow virtually imperceptible.

Frequently Asked Questions
Will manufacturers accept returns for IPS Glow?
Generally no. Manufacturers consider IPS glow an inherent technological characteristic of the panel type, whereas genuine backlight bleed that intrudes on normal content is covered under warranty.
