With a refresh rate of 144Hz and a 28" 4K IPS screen, Samsung primarily targets the gamer segment with this monitor. Its price as of its release has been set at ~$700, which indicates that it is one of the higher-end models. The monitor’s stand allows a wide range of motion, such as height adjustment, swivel support, and tilting. As far as build quality is concerned, there is not much to be excited about: it’s a fairly average run-of-the-mill plastic.

The monitor comes with one DisplayPort 1.4 and two HDMI 2.1 ports. The HDMI ports ensure an extremely fast data transfer rate of 40GBps between the graphics card and the monitor to meet the demands of the high refresh rate and the ultra-high screen resolution.

Samsung claims the response times are 1ms, but our test results indicate that this is an exaggeration, with the mean response times hovering around the typical 4-5ms range. However, a response time of 5ms is nothing to sneer at either.

The monitor also comes with support for both Nvidia’s G-Sync and AMD’s FreeSync. This adaptive refresh rate technology smoothens the gaming experience when the framerates are below 60 fps by synchronizing the monitor with the exact number of frames coming from the GPU output. This prevents screen tearing, a phenomenon where one part of the screen displays one frame and another displays another, which can be annoying.

The HDR support in this monitor is fairly basic at HDR400. This low brightness (440 nits, peak) coupled with a fairly average contrast ratio of 1000:1 means that the blacks would look more like darker shades of gray, which means the viewing experience would not be pleasant while viewing darker-looking scenes in games or movies.

As we remarked, the monitor targets gamers for whom HDR and contrast ratios may not be as important as smoother transitions. For that purpose, this monitor is plenty adequate.

  • Excellent refresh rate and response time.
  • Support for variable refresh rate.

  • Unremarkable HDR and Contrast Ratio.

The ASUS ROG Strix 27” comes equipped with a refresh rate of 170Hz on a 27” 1440p IPS screen. As mentioned in the very name of this monitor, this is a product geared towards those whose primary use case of this monitor is gaming. ASUS decided to set the release price of this monitor at $450, so it lies somewhere in the upper midrange category.

The monitor supports height and swivel adjustment but does not allow rotation. However, since this is a curved display, rotation is something other than what one might want to do on this display in the first place. As far as build quality is concerned, the base of the monitor stand is made of metal, providing some solid support.

The large screen size can also be used for office work which may involve multitasking and keeping many open windows side-by-side.

The ports included with the monitor are the standard one DisplayPort 1.2 and two HDMI 2.0 ports to provide a high refresh rate and resolution. The monitor’s very fast response time of 1 ms ensures minimal motion blur. This, coupled with a high refresh rate and support for Nvidia’s G-Sync and AMD’s FreeSync, results in an extremely smooth gaming experience.

The HDR quality and a peak brightness of 400 nits, coupled with a 1000:1 contrast ratio, leave much to be desired. This may be a dealbreaker if you want HDR content at its intended richness. If so, go with the ASUS VG27AQL1A, which has higher HDR quality but slightly slower response times, based on our tests.

This is a fairly good monitor if you intend to do high-end gaming that requires high refresh rates and graphics settings while being okay with an average dynamic range.

  • Below average contrast ratio.

The LG 27GL850-B is another addition to LG’s upper midrange monitors. With its 27”, 144Hz, 1440p IPS screen, thin bezels, and the absence of annoying RGB lights, which are common to gaming monitors, this monitor makes for a very graceful-looking device. The price at the time of its release was $500, which screams premium.

The monitor’s height, tilt, and orientation can be adjusted, but it does not support swivel. The casing of the monitor is made up of plastic. The monitor provides good viewing angles, which is generally expected from an IPS monitor. Its large 27” screen can also be useful for office work, especially when it involves a lot of switching between open applications.

The monitor has a very low input lag, translating into a smooth and refined gaming experience. This is a G-Sync-compatible monitor, which supports variable refresh rates and can be coupled with a GPU from either of the two rivals, AMD or Nvidia. There is one little catch, though, which we found from our tests: if FreeSync is used with an HDMI port, the peak refresh rate maxes out at 100 Hz.

The contrast ratio of 700:1 on this monitor is below average, which is outrageous for a device that almost costs a small fortune. If you can’t compromise on this, you might be better served with the AOC CQ27G1, which produces blacker blacks but is similar in most other important aspects. Not all is lost, however. The monitor has support for 1B colors, covering almost the entire sRGB range, which means that, besides gamers, it also is a good option for professional photo editors.

So, suppose your budget is not a handicap, and you are serious about building a gaming computer with all the usual bells and whistles but are not too hung up on its mediocre contrast ratio. In that case, this might be the right addition to your build.


Reasons to Buy

  • 1000R curved display.
  • Excellent response time.
  • Remarkable contrast ratio.

Reasons Not to Buy

  • Poor ergonomics.
  • Low peak brightness (250 nits).

With a decent feature set at an equally reasonable price of ~$300, the SAMSUNG 32" Odyssey G5 monitor can be a very good display choice for entry-level gaming, general usage, and content creation. However, the strongest selling point of this monitor is its 1000R curved display, whose importance can become more and more apparent as screen sizes rise.

Like most other gaming monitors, this one, too, comes with a refresh rate of 144Hz and a 2560x1440 WQHD resolution. The large 32" screen provides plenty of real estate for office work which may involve lots of switching between open windows. The casing is the usual plastic build that is characteristic of most screens in the market these days.

However, the ergonomics of this model could be more impressive as no adjustment can be made to the height, tilt, and orientation. If that is your pet peeve, you should check the Sceptre E325B-QPN168, a similar model for height adjustments.

The response time, at 1 ms, of this monitor is remarkable. The Odyssey G5 also supports AMD FreeSync Premium, which prevents screen-tearing, resulting in a much smoother experience.

With an above-average contrast ratio of 2500:1, this monitor, unlike most of its competition, doesn’t disappoint. It is also HDR10 compliant, meaning it has a color depth of 10-bit instead of the usual 8-bit. However, this is a bit misleading as the monitor is 8 bits but uses the A-FRC technology to simulate color artificially. So, it’s better than a typical 8-bit screen, but it’s not 10-bit in the truest sense of the word.

The brightness of the Odyssey G5 is a little too low at 250 nits. This may be fine, though, since you would usually use your desktop indoors, where this brightness level can be quite adequate. So, to sum up, if you are on a budget and are interested in a mid-range, good-value monitor, then the Samsung 32" Odyssey G5 might serve you very well.


Reasons to Buy

  • Good performance specifications but nothing out-of-the-ordinary.
  • Decent contrast ratio and brightness.

Reasons Not to Buy

  • Overpriced.
  • Design is not very user-friendly.

Following Apple’s footsteps, Razer, too, has started the tradition of releasing exactly one variant of their monitors each year. This year’s model features a 27" QHD 165Hz IPS screen. Razer released it for $699, which is a little too much to ask, considering the features it provides. The main highlight of this monitor is its slightly unusual design.

To keep things simple, the monitor only allows two movements, height adjustment and backward tilting up to 90°. This large tilt angle is required for connecting the cables, which is a bit of a hassle. The cables feature 90° connectors at their ends. This isn’t a user-friendly design, and someone might likely break their cables, whose replacement, as you might have already guessed, would come from Razer to keep design harmony.

The monitor also features thin bezels at 2.3mm to provide an immersive viewing experience. On its backside, we find a fabric finish, a design unique to Razer. There is also a small joystick on the backside at the lower right end, which can adjust the monitor’s display settings.

There is little to say about the performance aspects of this monitor, as these are the bare minimum at this price point. The monitor provides a decent response time of 4ms GtG and 165Hz refresh rate to ensure smooth gameplay. It is also G-Sync compatible and comes with support for AMD’s FreeSync. The contrast ratio at 1000:1 and a brightness of 350 nits are pretty decent, too, and result in an overall pleasant viewing experience. That being said, there is nothing particularly other-worldly about these specifications.

So, to conclude, this monitor is only for some, especially for someone who wants the best bang for their buck. If that sounds like you, then our recommendation would be the ASUS VG27AQ which offers almost identical specs at less than half the price. However, if brand loyalty is a bigger consideration for you than pricing, then, by all means, go for the Raptor.
