Best G-SYNC Monitors [Buying Guide]

The FreeSync and G-SYNC versions are focused on the same 27′′ 4K IPS display with 120Hz native refresh rate, 400-nit peak brightness, 1,000:1 contrast ratio, 10-bit color depth, and a broad 90 percent DCI-P3 color gamut.

In addition, both monitors endorse the HDR and carry the VESA entry-level DisplayHDR 400 certification.

This is where the inclusion of the G-SYNC module has a dramatic impact on performance!

To begin with, the Acer XB273KS has a VRR range of 30-144Hz, while the FreeSync models have a more limited range of 48-120Hz.

Because 4K is very challenging to drive, your FPS rate will definitely drop below 48FPS every now and then in in the the most recent titles, and the G-SYNC module will guarantee that you get a much smoother performance in the lower 30-48FPS range.

The variable amplifier of G-SYNC also guarantees optimum response time performance with FPS variances.

In fact, with Acer XB273KS, you will allow G-SYNC and HDR at the same time that you can not do with FreeSync models – only one can be enabled at the same time.

Although these monitors provide some HDR entry-level assistance, which ensures that you don’t get the full HDR viewing experience, you do get a major boost over SDR due to the wide variety of colors and higher brightness.

Any way, HDR isn’t meant to be the best reason to purchase this monitor.

The Acer XB273KS is ideal for anyone who want a 4K IPS monitor for eye-catching data visibility and/or color-critical research as well as a fast 144Hz gaming refresh rate.

Bear in mind that you will need to use scaling as 4K has a very high pixel density on 27′′ screen size. Scaling reduces the amount of screen real estate, but further increases the sharpness of the image.

However many people find that 1440p is sharp enough on 27′′ monitors, and because it is much less demanding than 4K, 1440p 144Hz gaming monitors will be chosen instead of 4K.

Of course, if you have a decent 4K gaming PC setup, whether you require maximum fidelity for work or other purpose, 4K 144Hz is the way to go.
