Hello everyone,
my U2413 Rev A00 has a strange brightness problem. I was wondering if anyone else has noticed this behaviour and if there's a solution. I usually set brightness to 25, and use the preset mode "color space / srgb". Strangely, the brightness is very low at times (like it is set to 0-5), but also very high (max I think). Even when I change the brightness setting (say, go from 25 -> 100 because it is so dark), the brightness changes but not like it should. So when I go to 100, it becomes a bit brighter, but only to a level that might be 25 on the normal brightness scale. Then I have to change preset modes and change back to get a normal brightness level again. I have not figured out when or why this happens. I only noticed it after 5 months now. It used to happen earlier as well but then I regarded it as "my mistake", but it definitely is not my mistake. I'm pretty disappointed with this after spending almost 500 EUR (650$) on this thing.
