HI. all have a small query relating to lcd monitor. i have seen lot of people talking abt premium panel or Tn panel pane...can ya let me know what exactly does it mean ? what effect does it have on LCD ..Wanna understand about this .. if someone can let me know what exactly it is ...:) ty u
 
TN = Twisted Nematic. Most of the LCDs on the market today are TN panels (as they are very cheap). TN panels are characterised by low input lag and fast response times and are hence, very popular with hardcore gamers. But they have very bad viewing angles and inferior color reproduction. A premium panel, on the other hand, is a very broad term and can represent anything; from a high quality TN panel to an IPS or PVA/MVA one. IPS is the highest quality panel, it gives the best color reproduction, black depths and best viewing angles; but at the expense of high input lag (in some cases as high as 60ms) and slow response time. PVA/MVA are a compromise between TN and IPS, combining good color reproduction (but not as good as IPS) and fast response times (again, not as fast as TN). PVA is similar to MVA but has higher contrast ratio. Now Dell has come out with a new "premium" panel, the 2209WA, which is an "eIPS" (enhanced IPS). It promises to give the image fidelity close to that of an IPS panel, but with lower input lag and faster response time and of course, lower cost. All this is a very general answer to your question, you will have to search on the internet for more information about all these panel types.

Correction - IPS panels have lower input lag and lower response times than P-MVA/S-PVA. The latter however have better black levels.

I was of the opinion that SPVA and MVA have faster response times than IPS? Wasn't MVA a commercially viable solution to IPS panels at some time? I could be wrong though.
 
S-IPS panels have better input lag than S-PVA/MVA It is a well known fact techster. PVA/MVA technology was Samsung's answer to LG-Philips IPS iirc as a cost cutting measure, not to improve on the response times for which overdrive was implemented. Overdrive and scalers infact increase the input lag.

Respose time != input lag

Frame delay = Response Time + Input Lag
 
How does TN panel ones affect gaming

one that i know of is the viewing angles, which for a single player looking straight wont affect

AFAIK, response time is best in TN, which helps

Any other major(NOTICEABLE) issues with TN panels for people to buy the IPS ones, even if they are twice as costly

TN is actually considered the best for online competitive gaming. It has very low input lag and very low response time (almost equal to CRT) so it makes that panel type the best one for hardcore gamers. TN panels are acceptable with respect to image quality when viewed straight on, but this also has its limitations. For eg., if you tilt your head slightly, you will see color shift. Also, TN panels that are 24" and above have color shifting (at the top and bottom of the display) by default because of the sheer size of the display.

In addition, color fidelity is not the best on a TN, as it is a 6 bit panel and does not reproduce all the 16.7 million colors accurately. Indeed, they have to use techniques called dithering and Frame rate control to simulate the required color. IPS panels are 8-bit, so they can display all colors accurately. Viewing angles on an IPS are very good, so you will see little to no color shift if you view the display sideways. Also response time of current IPS panels is almost equal to that of TN, so ghosting is not a problem with these panels. However, the input lag figure is still higher on IPS panels, it is not high enough to be noticeable if you are a casual gamer but for competitive gamers it is a disadvantage, as they will see their opponent 10-20ms after he has already seen them. But this input lag again is not too high, in real life it equates to about 1-3 frames slower than on a TN panel monitor. So for single player gaming an IPS panel is best, since you get amazing color reproduction and quite low input lag.
