Screen tearing

Hey! I just bought my new computer with GeForce GTX 970 and Intel core i7 4790-k. I noticed, noticed or noticed. I’ve seen alot of screen tearing specially in Metal Gear Solid V. The only games that only shows a little that i almost doesnt notice is GTA 5 and sometimes The Forest. I tried V-Sync but it doesnt work at all. In games and the control panel. I even get the tearing in videoes on YT, Netflix, Viaplay and that kind of stuff. And it makes me mad. Im using the monitor PHILIPS 236VL if that has something to do with it. PLEAS HELP.
