I’m assuming its a flat panel LCD screen….
Strictly speaking LCD don’t actually have a refresh rate, as they don’t refresh the screen the same way as CRTs
The phenonemenon you’re seeing is called ghosting, and is a result of a low response time of the screen(a response time is a measue of how quickly a pixel can be changed from one colour to another). Generally anything below 16ms will create ghosting. If you do a google search on your screen type I’ll bet you’ll find it has a response time of about 25ms, which aren’t really suitable for action movies, or gaming where the screen must update at a quick pace.
If it’s not an LCD ignore this babble :lol:
