MSI GP62 new screen installed

With the help of you amazing lads, i have been able to successfully replace my screen. THANK YOU GUYS! Did it 2 or 3 days ago, but have been busy ever since. The Bezel is SUPER THIN and you need to take care with it. Adhesive was the tricky part but gently prying for around 5 mins, lol basically romancing it gently did the trick. Without adhesive or double-sided tape on new screen, screen isn't exactly flush with the bottom part of the bezel area but i'm not too worried as it's not in 'bad' shape.

New screen is good. Higher Color Gamut (72% vs 45% sRGB on the LG), i think brighter too (300 vs 250 nits i think). However, i think i can notice some micro stutter in game i didn't notice on my old display. Lower response time? I don't know. It's like a half a second stutter noticed it in FIFA 17 and WWE 17. No Frame drops. Just those.

Can someone please check for me why? Screen names below
Old screen: LG LP156WF6-SPK1
New screen: AU Oprtonics B156HAN01.2

Can someone also recommend a good screen? Is LG LP156WF6-SPD1 a good screen? I love that it can get super bright too 400 nits i hear.

Anyways, opinions guys? Do i need to re-install something? I did re-install my Nvidia Driver already. I tried to do same for Intel, but apparently, 'a newer version of driver is already installed on your computer'.

See photos from my SURGERY below. Haha!
