im on the look out for a new monitor, im after 27 inch.
Have been looking at Asus PG278Q ROG but the price tag is too much looking for somethink under 350 pound mark.
Does anyone have much info on these G-sync monitors are they worth getting ?
*Most of this post is my own opinion*
I just took a quick look at what you have specified, personally I think is a bit steep cost wise. Sure it is a nice monitor and G-Sync is kind of cool if your graphics card is not capable of maintaining the refresh rate of the monitor.
This particular monitor is quite a high spec but I am under the impression that it is a TN panel to achieve 1ms response with 144Hz refresh rate.
TN panels while they are great for no input lag they do lack the great colour reproduction of an IPS monitor. Certain IPS monitors are available that have lower input lag anyway. 5-8ms on an IPS monitor is not noticeable by most and is a small price to pay for amazing colours.
G-Sync basically matches the refresh rate of the monitor to the FPS that your graphics card is pushing out which is supposed to make the experience smoother than the standard way of halving the FPS (Like when you drop below 60FPS with Vsync enabled it will default to 30FPS) if you dip below the refresh rate of the monitor which is noticeable by most people and will b visible as a slight judder or slowdown.
I have never used a G-Sync monitor myself but that is one heck of a premium to have this function.
Obviously you will need an Nvidia graphics card but if you have a high end graphics card such as a GTX 780 you will very rarely dip below the refresh rate of a monitor anyway anyway.
