TN (Twisted Ne­matic) dis­plays are the most widely used panel type dis­plays that make use of LCD tech­nol­ogy. Be­ing cheap and in­ex­pen­sive to make, they are suited for fast-paced gam­ing, as in games like Counter-Strike and Call of Duty.

Un­like other pan­els, TN dis­plays have rather snappy re­sponse times. The re­sponse times of cur­rent TN pan­els range from 1ms to 5ms. There are nor­mally two val­ues for re­sponse times, BTB (Black-To-Black) or GTG (Gray-To-Gray). Re­sponse time mea­sures the time taken for a pixel to go from black to white, and back to black again (or gray in the case of GTG). Faster re­sponse times re­duce the ef­fects of ghost­ing in fast-mov­ing scenes of movies and es­pe­cially video games. Mod­ern TN pan­els can also have a fast re­fresh rate, up to 120Hz and even 144Hz, which makes them suit­able for 3D con­tent.





TN dis­plays’ weak­nesses are that they have the worst color re­pro­duc­tion, low view­ing an­gles (un­der 170-de­grees), and con­trast ra­tios of any LCD panel tech­nol­ogy. Un­like most 8-bit IPS/VA based pan­els, TN is only 6-bit, which makes them un­able to dis­play a full 24-bit depth, 16.7 mil­lion color pal­ette. While they can mimic the 16.7 mil­lion col­ors of 8-bit pan­els (through a process called dither­ing), the re­sults aren’t par­tic­u­larly im­pres­sive or note­wor­thy. Who is it for: TN pan­els are the cheap­est of the lot, so they’re usu­ally the go-to mon­i­tor for those on a bud­get. How­ever, gamers ac­tu­ally ben­e­fit the most from the speedy re­sponse times, as color qual­ity and view­ing an­gles nor­mally come se­cond to a mon­i­tor’s abil­ity to keep up with the high frame rates and fast-paced ac­tions of mod­ern games.
