Which ASUS limits are yours
ASUS’s pixel policy for its monitors has four rows. The Zero Bright Dot (ZBD) models accept no bright dot at all: PG series monitors during the first 12 months after purchase, with up to 3 allowed from month 13 to 36, and ProArt PA series monitors for all 36 months. OLED models are left out of both and have their own row: those ASUS names, the PQ22UC, MQ13AH, MQ16AH, PA27DCE, PA27DCE-K, PA32DC, PG27AQDM, PG34WCDM, PG42UQ, PG48UQ and PG49WCD, allow up to 3 bright dots for 24 months. Every other model is non-ZBD, with up to 3 bright dots for 36 months. All four rows allow up to 5 dark dots. Pick the row that matches your model under Your ASUS display.
How ASUS counts a dot
ASUS defines a bright dot as one sub-pixel that stays on over a black screen and a dark dot as one sub-pixel that stays off on every screen, so the check counts sub-pixels: a dot on black that mixes two primaries, yellow for instance, counts as two bright dots. The policy doesn’t say how it counts a white dot (a whole pixel lit) or a black one (a whole pixel dark). The check shows those as 1 to 3 and says possibly over when the answer hangs on it. ASUS also excludes micro dots of half a dot or less, so a faint speck smaller than the sub-pixels around it may not count at all.
On a PG monitor, the first year matters
On a PG series monitor a single bright dot is outside the policy only during the first 12 months; after that the limit is 3. If a new PG monitor shows one, pick the first-12-months row, download the report and contact ASUS while that period lasts, with the receipt that proves the purchase date. On a ProArt PA monitor the zero-bright-dot limit runs for the full 36 months. Dark dots are never part of Zero Bright Dot: every model tolerates 5 of them.
Before you contact ASUS
ASUS says that when a display falls outside its Pixel Acceptance Detail it may repair or replace the unit, subject to verification and exclusions, and that the ZBD and standard terms can differ by region. The numbers here come from the pixel policy on ASUS’s US model support pages. Newer OLED models may be missing from ASUS’s OLED list, so compare with the policy on your own model’s page. Other brands set other limits: the Dell check, the HP check and the Lenovo check use them, and the dead pixel test works on any display.
