Nothing else to do here. The Nvidia drivers will intuitively detect your monitor’s capability to support G-Sync. If it does, it will automatically be enabled via the Nvidia’s Control Panel.


Verdict and Conclusion

We put the AGON Pro AG276QZD 27″ Gaming Monitor through several hours of 1440p gaming, and I’m happy to say I more than pleased with the results. The OLED screen is bright and clear, with deep blacks and vibrant colours. It offers an impressive contrast ratio of 80M:1 with an an eye-popping refresh rate of 240Hz and a fast GtG (Grey-to-Grey) response rate of 0.03ms. All these great features delivers a much smoother gaming experience.

The monitor is equipped with 2 x DisplayPort 1.4 ports, 2 x HDMI 2.0 ports, 2 x USB 3.2 ports, 2 x 5W speakers and a 3.5mm output jack. In order to get the full 240Hz refresh rate, I highly recommend you use some high quality DisplayPort cables that can support v1.4.

Other video features which make this monitor stand out from the crowd is the support for HDR10 and it’s compatible for Nvidia’s G-Sync as well as AMD’s FreeSync Premium. And as I mentioned earlier, the monitor is also compatible with PS5 and XBox offering QHD gaming at 120Hz, which great news for console owners.

So a 27″ monitor good enough for 1440p gaming? In my opinion … yes, as long as your graphics card can handle 2560×1440 resolution, then it shouldn’t be an issue. As you are aware, this monitor is flat and NOT curved, and comes with an aspect ration of 16:9. This makes it ideal for both gamers and content creators. Remember, not all curved monitors can be good for gaming. In most cases, a flat monitor with a high refresh rate and low response times could be better.

Now let’s talk price. For those who don’t know … most monitors on the market that are compatible with Nvidia’s G-Sync, cost quite a lot more over FreeSync compatible monitors. Wny? G-Sync monitors contain the extra hardware needed to support Nvidia‘s version of adaptive refresh, with a typical price premium of $200 or more over a monitor of similar spec.

So with that said, the AGON Pro AG276QZD 27″ Gaming Monitor right now costs a whopping USD $999 (but recently reduced to $799).


Final Words

If price is of no concern, then the AGON Pro AG276QZD 27″ Gaming Monitor is definitely a luxury item for the hardcore gaming “whale” or esports professional. The premium price is easily justified by its high specs, which includes a lightning-fast refresh rate of 240Hz, an unmatched GtG response time of 0.03ms, and an OLED display supporting HDR10 and G-Sync compatibility.
