I hooked up the 920t to my test rig which runs an ATI Radeon 8500. It comes with dual analog and digital connectors, so it's useful when testing monitors.
The first user test I ran was just playing a DVD. I had the re-master Akira Special Edition on me, so I threw that in and fast forwarded to the stadium sequence. Lots of fast moving animation should give it a good workout.
Not much of any ghosting or slowdown during action sequences during playback.
I didn't have any games installed on this test rig, however, it did have 3DMark03 installed. So I ran the demo sequence to mimic gameplay.
Overall, the Syncmaster 920t provides great performance at 19 inches. Although the response time is only 25ms, ghosting was not as much of a problem. The brightness and high-contrast of the unit is great. The use of Magicbright is useful, as long as you do not install the Magictune software. Keep the adjusting to the unit, not the software in my opinion.
If you are in the market for a beautifully designed 19" LCD, check this model out, you won't be disappointed.
