What makes a 240Hz gaming monitor actually worth it?

I did some digging and found my winner for the best 240Hz gaming monitor,and the difference between 144 and 240 is there, albeit only if you have a GPU that can keep up with the faster frame rate. The refresh rate is only as important as the response time, a 240Hz panel that has slow response times will have ghosting in fleeting movements. Even bigger roles are assigned to the use of panel technology, as OLED panels here offer a significantly higher motion clarity and color accuracy than most IPS panels at the same refresh rate. If you are looking for higher frame rates, you will need to have adaptive sync support (G-Sync or FreeSync) to prevent screen tearing. For most competitive shooters, response time and input lag are more important than resolution; for all other games, it’s a balance.
