This is an old thread, but in case anyone comes across it while searching for the topic, the latest Samsung G7 Odyssey panels from Samsung don't have any ghosting or smearing. With the latest firmware update, there's no flickering, either. I've got the 27" version and the image quality is awesome - much better than any IPS monitor (I've tried the LG 27GN950 and the 27GN850 but couldn't stand the massive IPS glow and BLB issues). The only downside is the extreme 1000R curve which is unnecessary on a 27" 16:9 screen, but if you can live with that, look nor further. After colour calibration, the picture looks so good that I doubt we'll see anything better until or unless OLED-based gaming monitors start to become available.
