Up until recently all 120Hz+ LCD monitor intended for gaming (regardless if for stereo 3D use or not) were using TN-based LCD panels due to the fact that this technology provides the best results in terms of pixel response and that is something you need if you want to have a higher refresh rate. TN LCD panels may be the fastest in terms of response, however they have other no so good aspects when compared to VA-based and IPS-based panels, but fortunately we now have what seems to be the first gaming oriented 120Hz LCD monitor with a VA-based panel from Eizo (it does not support stereoscopic 3D!). If you are not familiar with the name Eizo it is probably because up until recently the company was focused on professional monitors and it just recently started making monitors targeted at gamers.
EIZO Foris FG2421 is actually is not their first gaming monitor, but is the first one that is able to work at 120Hz refresh rate and as already mentioned it is nt with a TN panel. Eizo markets this monitor as a 240Hz gaming monitor, however this can be a bit misleading if you don’t read the details, in fact it is a 120Hz monitor that has a built-in processing to simulate 240Hz. Eizo calls this function “Turbo 240” and you can enable or disable it from the OSD menu of the monitor, what it does is doubling the frames (not interpolating, but doubling) and strobing the backlight in between them and the end result is a significant reduction in motion blur. This is pretty similar to how the 3D Lightboost technology on more recent 3D Vision-compatible monitors functions, although there is no frame doubling with them. Definitely an interesting thing to see as this Eizo monitor can turn out to be a great alternative to buying a 3D Vision-ready monitor that you may not use in stereo 3D mode at all, especially considering the fact that there are no other 120Hz displays out there that use better LCD panels than TN, so if you are not into 3D and hacking Lightboost to work in 2D mode you might want to check the EIZO Foris FG2421 out. Eizo also promises low input lag (less than 10ms) and no noticeable flickering with reduced brightness by using DC control and high rate PWM (Hi-PWM) control for driving the backlight instead just PWM.
