The answer to this question depends greatly on how you will use your gaming monitor. If you are using it for your leisure time or competitive gaming, a TN panel will be perfect. As we have mentioned above, this type gives you a response time of only 1ms. Another advantage is that these panels are usually more inexpensive than the others as they are cheaper to manufacture. However, the colors do not look very good from certain angles.
On the other hand, if you are planning on using your panel for professional gaming, we suggest that you get an IPS panel, as they have much brighter and more vivid colors. You can notice much smaller details with this type of panel. Finally, if you are looking for normal use, a VA panel is enough.
