How to Look for a Good LCD:
Here are some things to look for when buying a new LCD (not in any order)
1. Panel Type - Not all LCDs use the same panel. You will often (esp. on newegg) see TFT under panel. All LCDs have a TFT panel. The question is do they use a TN, IPS, MVA or PVA Panel.
TN Panel: The TN panel is the cheapest panel to produce and is the one most LCD manufacturers use due to this. These panels have the fastest reponse time, however, they produce the worst color and the color will slightly change when you move up or down / left to right. They also have limited viewing angles.
IPS Panel: An IPS is one of the best panels available for an LCD. These panels offer very good viewing angles and color. However, these cost much more than the TN panel and have higher response times.
MVA Panel: This panel is more of a hybrid between a TN and IPS panel. These panels offer a big viewing angle and color (IPS panel is still better in these departments) with a fast response time. However, these panels cost more than the TN panel, but less than an IPS panel.
PVA Panel: Very similar to the MVA panel. However, these panels offer much higher contrast ratios when compared to the MVA panel.
