16 months ago I posted a video showing the Panasonic 42″ GT25 being used as a main 3D Computer Monitor. Most people thought there would be issues like burn-in very quickly. As it turns out, there have been no issues except for temporary image retention that goes away after a few seconds at most. I have the display calibrated in THX mode with screen being driven in component mode. The pixel orbiter is set to 1 minute (I’ve never noticed it active) and set the Windows 7 taskbar to hide unless the mouse is over the bottom of the screen. No burn-in anywhere.
The only change has been an improvement in the display quality over the past few months. High Frequency noise in black areas has decreased, and the gamma shift related to shifting black levels has also greatly subsided, possibly even gone away. The monitor was a fantastic purchase at the time, and you’d be hard pressed to do better at the size. Pixel density may not be the greatest, but it’s as close to a large OLED screen that you will be able to purchase in the foreseeable future.
