I've bought Benq FP202WA, and after few hours of setting it up and testing I've realized that backlight is flickering at 40-70Hz, depending on brightness setting. With brightness set over 80-90 flickering is gone, but screen is too bright.
I've took to registered service center and after waiting for 2 weeks they've said that everything is fine. After another look at the picture it was obvious to me that screen is still flickering. And now, after sending it back to service and waiting for 2 more weeks they again said it's fine!!!
Any know how can a lcd backlight be tested for this kind of flickering? And how to explain the problem to the people in service center - I've told them already that backlight is flickering when brightness is lover than 80-90 and that it's flickering at 40-70Hz but they looked at me like I don't know what I'm talking about....
The only thing I could come up with is using digital camera and setting exposure time to 1/50 seconds (50Hz) when u can clearly see that backlight is pulsating / flickering...
