    Sorry,

    Another Newbie question. But what does IPS and TN stand for and what is the difference?

    Monitor challenged.

    No point going in to specifics here as it is covered very well on wikipedia:

    Most people buy them for the better viewing angle (multi-monitor arrangements and rotation of displays benefits here) or for colour accuracy - something that is important for print work and the other key area TN panels lack in comparison to IPS.

    This video highlights differences in viewing angles between IPS and TN:

    TN stands for "twisted nematic." Almost every laptop screen or inexpensive LCD monitor you'll run into uses a TN panel. TN panels offer very fast pixel response times, but they often have somewhat poor color fidelity, and poor off-axis viewing, meaning that you will see a noticeable shift in colors if you look at the screen from an angle. Additionally, many seem to be 6-bit panels, which means that they can actually only display about 262,000 colors, but use dithering to approximate the "millions of colors" you expect a modern display to show you.

    IPS stands for "In-Plane Switching." The iPhone, iPad, iMac, and Apple Cinema Displays all use IPS panels, but no Apple laptop ever has, unfortunately. Many moderately-priced LCD monitors use IPS panels (though some, and many LCD TVs, use MVA or PVA panels). IPS panels offer slower pixel response times, but they have very good color fidelity, and have excellent off-axis viewing angles (generally 178 degrees).

    If you are looking for an external display, definitely have a look at both panels styles to see which fits your needs best. Many people who like to watch movies or play games seem to like the fast response times of TN displays. For my money, I definitely prefer IPS - color shifting annoys me so much. Anyway, hope this helped.
