So i got 2 BenQ RL2455HM but one of them seems brighter then the other ive tried messing around with the settings but i dont completely understand how i can make them look the same. Please help!
If the two displays were purchased at different times or places, there is also the possibility that they will be different due to variations in LCD panel and backlight characteristics between component batches.
They usually have a preset for several picture modes, like "gaming", "text", "photo". Try setting everything to the same values (brightness, contrast, etc... or just reset the settings) and then ONLY change the color mode. What I usually like the most is the text setting.
