Does the monitor produce any noise now that it doesn't have a fluorescent backlight? Also, does this one have any fans like older & smaller led back-lit monitors?
If you put your ear to the back of the monitor, you will hear noise, but noise is not a problem when using the monitor.
I don't see or hear a fan, but there may be one somewhere. If there is one, it's very quiet.
The monitor runs remarkably cool - very little heat is generated.
It really is very nice other than the color instability at minimum brightness.
One other thing to note is that this monitor has no frills. Just one input, no OSD, and only brightness and graphics mode buttons. Build quality is about the same as the 305T - nothing fancy. It's one of those products where it's clear that there's a lot of scope for price reduction in the future.
It has a scaler - I tried scaling 1920x1200 to 2560x1600, and it works fine, but the quality of the scaling is not as good as on my 3008WFP.
