i am trying to search/find info on the VX922 and its panel, a guy in another thread is saying something about the 8-bit vs. TN panel. I can't find anything on it and am starting to doubt his remarks but my testimony to the VX922, rather 2ms to 8ms response time goes like this. You CAN tell a difference between the speeds of these numbers as i have when i booted my pc up with a 214T Samnsung 8ms and my now only lcd the VX922 2ms (i had both lcd's at the time of my test) As soon as i saw the difference I couldn't justify the price of the 214T compared to the VX922's performance. If you know about the 8-bit vs TN panel difference and find it a factor in purchasing this monitor more power to you. My ignorance to the 8-bit vs TN panel is BLISS!!!
Thank You,

He's right. The VX922/930BF/940B are all 6-bit TN panels. They can display a maximum of 2^(6*3) colors, which equates to 262,144. With 8-bit IPS/VA panels, 2^(8*3) colors can be reached, 16,777,216. That's also as much as your computer can send it. "32-bit" = 24-bit color + 8-bit alpha. The 24-bit color in each of its components is 8-bit. The alpha can always be accomodated. I believe the graphics card does that job.
The way the TN panels get away with it is that they dither. Dithering is just creating one color from multiple ones, so it tricks your eyes. With dithering, 16.2M colors can be reached (still not 16.7M). But even the 16.2M colors aren't perfect. It's impossible to have one pixel next to another and both be out of the 6-bit LCD's range, thus there's a limitation, particularly in gradients. So an 8-bit panel will ALWAYS reproduce a greater range of colors given the same backlight/electronics as the 6-bit one. It so happens that TN panels also have inferior viewing angles.
The VX922 hits in the range of probably 8-10 ms. in reality. The 214T is probably more like 13-15 ms., so both are exaggerated by the manufacturer. A true 2 ms. might be indistinguishable from a true 8 ms., but we can't tell, because no LCDs have hit those speeds (at the maximum) yet.
