Samsung SyncMaster 2233RZ 120Hz Monitor

Check out the review of the new Samsung 120HZ refresh rate monitor is from Nathan at Tweeknews. The 22 inch widescreen is one of the first to feature a refresh rate double the standard 60hz:

"Till now, most monitor releases have been carbon copy releases of technology that has been out for over three years. An image quality tweak here, a design tweak there was all the consumer could expect. But this monitor is different in a big way. The technology difference contained within this rather standard monitor screams out loud in a crowd of your average everyday LCD computer monitor. No longer does the gamer have to settle in order to enjoy their games and no longer do they have to wait. The 120hz technology is here and I hope it is here to stay."
