In your search for the top gaming monitor you may have come across someone talking about why they’d purchase an IPS panel, TN panel, or vice versa.
TN or twisted nematic panels are used for most consumers because they are less expensive, more energy efficient, and have lower response times which allow them to have smooth video and gaming sequences. TN panel monitors are generally not used for photo editing because they only use 6 bits per RGB color for a total of 18 bits. In order to produce the full 16.7 million colors available for “true color” dithering is normally used.
IPS or in-plane switching monitors use at least 8 bits per RGB color (24 bits) and can display accurately the 16.7 million colors for true color. Some have gone beyond 8 bits for 10 or even 12 bits per color allowing them to produce over 1.07 billion colors. The advantages of having an IPS panel for gaming is really all in the picture. If you do choose an IPS panel monitor I recommend you find one with a pretty low response time like the Dell UltraSharp U2711 which has a 6ms response time, quick for IPS, and a 2560×1440 resolution beyond full high definition which looks unbelievable in games. On the downside if you want to purchase an IPS panel like the UltraSharp, then you should be prepared to spend over twice the price of what you would for a standard gaming monitor.
A good 27 inch gaming monitor TN alternative would be the Viewsonic VX2753MH-LED. This model has a fast 1ms response time a 1980×1080 resolution and at under 10 pounds is extremely portable for carrying to LAN parties and trips. With a 30 million:1 contrast ratio and LED technology that allows it to completely turn off the LED lights you also get a great looking picture. Although this is one of the best gaming monitors it’s important to note that it is not VESA compliant and if you want a monitor that is you’ll need to look elsewhere.
Overall some have experienced the tearing that occurs from a low response time, but with new IPS technology that has lower response times this is pretty much unnoticeable. If you have the extra cash, and don’t need 3D capability, then strongly consider going with an IPS panel monitor.
