5 Best 4k G Sync Monitors: Reviewed & Compared

If you have an extremely powerful gaming rig that is capable of pumping out crazy high frame rates at a huge resolution, then there is absolutely no reason why you should not consider a premium gaming monitor.

The only issue, however, is with the adaptive technology featured on gaming displays. Basically, if you want adaptive technology, the options are binary, you either have to go for AMD FreeSync or Nvidia G-Sync.

It goes without saying that you would need the respective brand compatible graphics card. Meaning, AMD FreeSync does not support NIVIDIA graphics cards and vice versa.

Here we will check out the best 4k G Sync monitors for those who have a powerful Nvidia Graphics card.

Things to Note

These monitors can get very expensive.

The cheapest option you have is more than $500 currently, therefore, you will need to set a pretty significant budget for a gaming monitor with G-Sync at 4k Resolution.

As far as the price comparison goes, AMD FreeSync monitors are the cheapest for offering adaptive technology.

However, the latest AMD FreeSync 2 monitors are almost as expensive as the NVIDIA G-Sync enabled displays.

5 Best 4k G Sync Monitors Reviewed

1. Acer Predator XB281HK bmiprz – 28″ – For Casual Gamers – Most Affordable

Acer Predator XB281HK bmiprz 28-inch UHD...
  • 28" UHD (3840 x 2160) Widescreen with NVIDIA...
  • Response Time: 1ms
  • Pixel Pitch: 0.16 millimeter. Flicker less...
  • Signal Inputs: 1 x Display Port 1.2 & 1 x...

The first monitor in our list is also the most affordable option in this list.

Of course the term “affordable” here is relative since compared to the actual 27 inch budget displays, this costs about 5 times more.

This is also the only monitor in this list that offers a TN panel.

If you are aware of the different panel technologies, then you will be quick to note that TN panels do not have as great a color reproduction and viewing angles as IPS panels, but they have a very fast response time.

Another thing to note here is that not all panels have the same color quality. For example, despite being a TN monitor, it offers a 10 bit color depth as supposed to 6-8 bits on conventional TN monitors.

The higher the bit depth, the more colors the monitor can show.

Of course, the main highlight of the TN panel monitors is their very fast response time. This monitor has a response time of 1ms therefore, if you want to minimize motion blur/Ghosting effect as much as possible, then this is the way to go.

It also offers a fast 144Hz refresh rate for making your gaming experience smoother. You will need the cream of the gaming desktop to support gaming at ultra setting on 4K at 144 frame rates.

Finally, this is the only monitor in this list that offers larger than 27 inch display i.e 28 inch.

While the design of the monitor is quite appealing, the only issue it suffers from is the thick bezels. All TN monitors suffer from the same issue.

All in all, if you came here looking for a quality premium option at the most affordable cost, then this is one of the best 4k G Sync monitors out there.

2. Acer Nitro XV273K Pbmiipphzx – 27″ – G Sync Monitor for Gamers and Content Creators

Acer Nitro XV273K is a mid range monitor in this list that offers features to satisfy both the gamer as well as the designer in you.

Primarily, this is a gaming monitor with an IPS panel, 4K resolution and NVIDIA G Sync Technology.

The main highlight as far as the gaming in concerned is that this is one of a rare few monitors that offers an IPS panel with a response time of 1 ms.

The native response time is higher, however, the Visual Response Boost (VRB) technology enables this monitor to achieve the Moving Picture Response Time (MPRT) of 1ms.

While this a beautiful 27 inch IPS gaming monitor, it can do so much more.

For starters it covers 90% of the DCI-P3 color space as well as 100% of the sRGB color space. DCI-P3 is essential for video creators and sRGB is equally important for digital content creators.

You can even use these color spaces on your games. For example, the DCI-P3 will give your gaming experience a more cinematic feel.

In addition to that, it also offers the much coveted DislayHDR 400 technology. While HDR is great for photographers, you can use this color enhancement feature on gaming as well.

Finally, to further enhance the colors, Acer Nitro XV273K uses the Quantum Dot LCD technology.

In the end, if you are looking for a mid range all rounder option, then this is one of the best 4k G Sync monitors.

With this monitor we are venturing into the most expensive realm of computer displays.

This is a monitor that can cost as much as a fairly powerful gaming rig itself.

Whether this monitor is well suited for you depends on your needs as well as your passion for perfection.

For starters, this monitor covers the expansive Adobe RGB color space.

This essentially makes it a monitor that is perfect not just for gaming but also perfect for print media industry.

Furthermore, this also offers the rare Local Dimming technology. With this feature, the backlight is divided into several zones.

Therefore, depending upon the image shown, the zones turn on and off individually. As a result, the whites are brighter and the darker zones are darker. This adds more fidelity to the image.

Other than that, it offers a beautiful exterior, 144 Hz refresh rateQuantum Dot LCD, as well as the HDR technology.

There is absolutely no doubt that this really is one of the best 4k G Sync monitors out there for both gaming and designing.

Unfortunately, this may be beyond most people’s budget.

You don’t have to take my word for it, listen to what Linus has to say.

This a super expensive monitor slightly costlier than the Acer Predator X27 bmiphzx above.

While you can say that both ASUS ROG Swift PG27UQ and Acer Predator X27 bmiphzx offer more or less the same type of specs, the ROG certainly takes the lead.

Firstly, the ROG is a supremely beautiful display. It even features the ASUS Aura Sync technology that illuminates the RGB ambient lights and pulses them depending on the sound on your game or the beat of your music.

Secondly, it offers gamer centric features such as a 144Hz refresh rate, G Sync and several gaming modes.

Thirdly, it offers suitable features for designers and photographers such as DCI-P3 coverage and 100% Adobe RGB coverage.

Fourthly, it features color enhancing features such as Local DimmingHDR and Quatum Dot LCD.

As such, there is absolutely no stone that this monitor leaves unturned when it comes to the overall package.

Basically, if you have deep enough pockets, then this is not just the best 4k G Sync Monitor, this is one of the best monitors overall.

  • Brightness - 300 cd/m2, Dynamic Contrast...
  • Connectivity-Display Port 1.2, HDMI 1.4, (4)...
  • G-Sync Compatible, Speakers, Audio...

Finally we have this monitor that does not look as good as the others on paper, but has surprisingly garnered high popularity.

This is a mid range 4k G Sync monitor with a 27 inch panel60 Hz refresh rate, 4ms response time and an IPS panel.

Despite the fact that it neither features 144Hz refresh rate nor any color enhancing features, this has been loved by its buyers.

We personally find the Acer Nitro XV273K Pbmiipphzx as a much better option. It not only offers 144Hz refresh rate, 1ms response time and color enhancing features, but also costs almost the same.

Therefore, despite its popularity, we will suggest that you wait until a good discount is available for AOC Agon AG271UG if you are serious about it.


The best 4k G Sync monitors are expensive. They certainly do seem to cost a fortune.

However, if you have a powerful gaming rig with an NVIDIA Graphics card then there is absolutely no reason why you should not consider one of these displays.

Afterall, you shouldn’t bottleneck or waste your gaming rig’s potential with a lackluster monitor.

It is worth noting here that one of the best, if not the best, gaming monitors in the market is a 4K G Sync monitor i.e ASUS ROG Swift PG27UQ. It is really heavy on the wallet, but there is nothing like it in the market.

There are also some fairly good and relatively affordable deals in the market like the Acer Predator XB281HK bmiprz.
