Thank you guys.
I've decided to go with 27" IPS 1080p Monitor. I will visit saddar after tuesday and purchase some of HP ZR2 series or equivalent.
I've decided to go with 1080p resolution instead of 1440p because I also play PS4 and I've read on multiple places that ps4 graphics get blurred on 1440p native monitor because of upscaling.
If any of you guys had experienced opposite then do let me know.
