Hi:

I was considering a new monitor and I need some advise from experts here.

My PC used mostly on gaming, and working. I am using 10 year old Acer 24 inch FHD monitor currently, thinking of getting another one due to the old monitor getting dimmer now.

Still want to run on FHD resolution, but would like to have some upgrade:

Perhaps 27 inch FHD? or should I stick to 24 inch?
Looking for 75Hz refresh rate, will it gives smoother experience on Windows and Games? (My GPU is GTX 1060 and might upgrade to 1070Ti or 1080.)
IPS panel, will it makes huge difference than TN?
Response time 5ms or less.

Any recommendation/advise on my requirement above?

VX2458-C-mhd, this model G-sync ready?

Need to know is VX2458-C-mhd G-sync compatible?

Thanks for your info.
