After few weeks I noticed distubring issue with this monitor. I'd like to know whether it is design problem or just my unit is defective.
The monitor is connected via DVI-D using native resolution. The problem can be demonstrated by displaying blue color (default Windows XP desktop backgound) or dark-grey (default Windows "empty" workspace color) on the whole screen. I notice some "flickering" or "wave motion" in the solid color similar to slow refresh rate on CRT monitors. It can not be a backlight issue because it is not visible on white color at all. Setting CONTRAST to the default value 50% (which is too high for normal usage) seems to help a bit but I prefer values around 37% and BRIGHTNESS 19.5% where it is very visible. Especially if you look slightly under the bottom side of the monitor.
I bet most of people wouldn't notice it at first glance. Unfortunately I'm sensitive to such effects, I couldn't stand any CRT monitor with refresh rate under 90 Hz.
Can anybody confirm this problem ? Thanks in advance.
