The 1440p 144 Hz resolution – refresh rate combination has almost become a new standard for gaming, as it has the best of both worlds: crisp visuals, paired with smooth framerates. Add to this the fact that new-generation consoles, like the Xbox Series X, can now natively support 1440p at 120 Hz – and the release of the new Nvidia GeForce RTX 30 Series and AMD Radeon RX 6000 Series GPUs, which have made this resolution & framerate combination more affordable – and we can see how it is slowly becoming the new norm for both competitive and triple-A gaming. 

Perhaps the most popular of all 27-inch 1440p 144 Hz displays, in an oversaturated gaming monitor market, is ASUS’s TUF VG27AQ. This monitor is time-tested and has made a reputation for its excellent performance and high durability. ASUS is generally known for manufacturing quality monitors with incredibly low input-lag, and have been a standard for many competitive gaming tournaments for this very reason.

To compete with this offering from ASUS, LG has released the 27GL850-B, which features a LG’s proprietary Nano IPS panel and a simulated 10-bit panel depth, used to generate over one billion colors. 

But does the LG 27GL850-B surpass the ASUS TUF VG27AQ in overall performance, and is it worth the extra cost associated with it? To answer this question we will compare both options – in terms of manufacturer specifications and real-world benchmarks – and declare a winner depending on different modes of application: like competitive gaming, triple-A gaming, or general use & productivity.

Appearance – ASUS TUF VG27AQ


Though beauty is in the eye of the beholder, it is difficult to argue that the ASUS TUF VG27AQ doesn’t have a much more sleek and simplistic design versus the LG 27GL850-B. The VG27AQ has a versatile look that can make it appropriate not just for a gaming setup, but even for an office setting. On the other hand, the LG 27GL850-B, with its plastic red accents running across the back and behind the V-shaped portion of the stand, give it an overall cheaper look.

Both monitors have equally thin borders, at 0.4 inches (1 cm), so they can be paired with other monitors for multi-display setups quite nicely. The overall thickness for the ASUS TUF VG27AQ (with the stand) is 5.4 inches (13.7 cm), while the LG 27GL850-B is quite thicker at 6.5 inches (16.5 cm). If you wish to remove the monitor from its stand and have it be mounted on a wall, the LG 27GL850-B does have a thinner screen at 2.2 inches (5.6 cm), versus the VG27AQ’s 2.8 inches (7.1 cm) of screen thickness.

Resolution & Refresh Rate – TIE

 The resolutions of these monitors are identical at 2,560 x 1,440, but when it comes to their refresh rate, the ASUS TUF VG27AQ does have the ability to be overclocked and increase its refresh rate to 165 Hz. The reason why this does not give the VG27AQ the edge over the LG 27GL850-B in this category is because this feature will only affect very few users. To reach a framerate high enough to take advantage of this overclocked refresh rate will require the best PC hardware equipment the market has to offer. According to benchmarks by Techspot, even the Nvidia GeForce RTX 3080 can only reach an average of 153 FPS at 1440p; in tests carried out for 18 different titles. Additionally, this overclocked refresh rate can only be utilized if the monitor is connected via a DisplayPort, as otherwise the monitored will be limited to 144 Hz when using HDMI.

Display – TIE

IPS monitors generally have great viewing angles, and these two models do prove this characteristic advantage. In the horizontal axis, both monitors experience a color shift at angles above 50 degrees and a color washout above 45 degrees. Their vertical viewing angles are not as impressive, as the colors displayed by the ASUS TUF VG27AQ begin to shift at an angle of 40 degrees from below and 42 degrees from above, while the LG 27GL850-B sees a color shift at just 33 degrees from below and 39 degrees from above. Though both monitors are excellent for screen sharing – used for multiplayer games, consoles, or just watching movies – they aren’t meant to be viewed from above or below; which should be taken into account for multi monitor setups.

Contrast & Brightness – ASUS TUF VG27AQ


The trade for the excellent viewing angles of the IPS panels is the poor contrast ratios that go with them. That being said, the ASUS TUF VG27AQ does have one of the best native contrasts found in any IPS-panel monitor. The contrast of IPS panels usually ranges from 800 to 1,000 to one, but for the VG27AQ it was measured to go beyond its advertised 1,200 to one, reaching 1,247:1 during tests carried out by Compare this to the LG 27GL850-B’s benchmarked 735:1 contrast ratio, and we see a huge discrepancy between the two.

Brightness levels are very similar between both options, with the ASUS TUF VG27AQ reaching 311 to 329 nits at SDR, and 329 to 357 nits for HDR, while the LG 27GL850-B reaches 315 to 347 nits for SDR, and 341 to 362 for HDR peak brightness.

Because of its far superior contrast ratio, the advantage here must go to the ASUS TUF Gaming VG27AQ.

Color Range – LG 27GL850-B

LG 27GL850-B

Where the LG 27GL850-B lacks in contrast, it makes up for it in its color reproduction. With the use of Frame Rate Control (FRC) – a function which quickly cycles between color to give the impression that intermediate color tones are being generated – the LG 27GL850-B is able to reproduce over a billion colors. Add to this the light absorbing nanoparticles on the backlight – that rid the display of excessive wavelengths – and this monitor can display an impressive array of colors.

To be more specific, the 27GL850-B can reproduce 135% of the sRGB color space, 84.2% of the Adobe RGB color gamut, 98% (77.8% benchmarked) of the DCI P3 color space, and 68.4% of the Rec. 2020 color spectrum. The ASUS TUF VG27AQ can recreate 99% of the sRGB color space, 74.2% of the Adobe RGB color gamut, 69.8% of the HDR DCI P3 color space, and 56.7% of the Rec. 2020 color spectrum.

Overall, a considerably wider color gamut range for the LG 27GL850-B.

Response Times – LG 27GL850-B

LG 27GL850-B

The LG 27GL850-B also holds a lead in regards to response times, where it has a total response time of just 8.3 milliseconds in its native resolution and framerate; with an overshoot error of 5.4%. This is in its “Fast” overdrive setting, the others being Off, Normal, [Fast], and Faster. At 60 Hz, this value barely increased to just 9.6 ms, with only 1.3% overshoot on its Normal setting.

The ASUS TUF VG27AQ has six overdrive settings (0, 20, 40, 60, 80, 100), and on 80 – which has the best balance between response time and overshoot error – we see a total response time of 11.5 ms with 5.8% overshoot. At 60 Hz the monitor has a 16.9 ms total response time with no overshoot error (at the “0” overdrive setting). 

At 60 Hz the difference in response times between the monitors is quite sizeable, so if you plan on playing games at 60 FPS (like fighting games that can only play at 60 FPS) then there may be some motion blur with the ASUS TUF VG27AQ.

Input Lag – ASUS TUF VG27AQ


If you don’t mind the motion blur, the ASUS TUF VG27AQ does have lower input lag at both its native resolution and framerate, as well as at a 60 Hz refresh rate: 3.5 ms for the former, and only 8.3 ms for the latter. With VRR (Variable Refresh Rate) enabled, these metrics increase to 6.3 ms and 9.3 ms respectively – which is still superb.

The LG 27GL850-B has 4.3 ms of input lag at 1440p and 144 Hz; which goes up to 14 ms at 60 Hz. With VRR enabled the 144 Hz input lag increases to 4.7 ms, and the 60 Hz input lag decreases to 13.2 milliseconds. Not as good as the ASUS TUF VG27AQ, but still respectable results for the LG 27GL850-B.

Ergonomics – ASUS TUF VG27AQ


In terms of ergonomic flexibility, the LG 27GL850-B is quite limited, only allowing for a height adjustment of 110 mm, a right pivot of 90 degrees, and a forward & backward tilt of 5 and 15 degrees. On the other hand, the ASUS TUF VG27AQ allows for a height adjustment of up to 130 mm, a clockwise and counterclockwise pivot that can reach landscape and portrait orientations, a left and right swivel of 90 degrees, and a forward and backward tilt of 5 and 33 degrees. Overall, a much more versatile monitor when it comes to ergonomics.

Both monitors can be removed from their stand and mounted via a VESA mounting interface standard of a 100 x 100 millimeters.  

Power Consumption– LG 27GL850-B

LG 27GL850-B

Despite both monitors having similar performance, the LG 27GL850-B consumes only 39 Watts on average, whereas the ASUS TUF VG27AQ consumes 65 Watts on average – making the 27GL850-B more power efficient by up to 40%. The LG 27GL850-B has a B energy efficiency class, a maximum power consumption of 65 Watts, and an estimated annual power consumption of 57 kWh per year.

Connectivity – LG 27GL850-B

LG 27GL850-B

More and more gaming monitors are utilizing USB 3.0 ports, allowing one to plug their peripherals directly to the monitor, which is itself connected to the PC via an upstream USB 3.0 port. 

Unfortunately, the ASUS TUF VG27AQ is devoid of any such ports, having only two HDMI 2.0 slots, one DisplayPort 1.2 socket, and one 3.5 mm audio-out jack. On the other hand, the LG 27GL850-B has two USB 3.0 downstream and one USB 3.0 upstream ports, two HDMI 2.0 slots, one DisplayPort 1.4 socket, and one 3.5 mm audio-out jack.

Both options have High-bandwidth Digital Content Protection (HDCP) for their connectivity.


Feature wise, these options have much of what one would expect from a gaming monitor. 

The ASUS TUF VG27AQ has a 5-way OSD joystick to better navigate its menus, AMD FreeSync and Nvidia G-Sync compatibility, Flicker-free technology, ELMB (Extreme Low Motion Blur), GameFast Input technology, GameVisual, Shadow Boost, Trace Free technology, and GamePlus (with a crosshair overlay, a timer overlay, an FPS counter, a display alignment tool, and a Sniper mode which places a dot in the center of the screen and magnifies a small area around it).

The LG 27GL850-B also has AMD FreeSync and Nvidia G-Sync support, Flicker-free technology, a black stabilizer, and a crosshair overlay; as well as DDC/CI (for calibration input), Dynamic Action Sync, and LG’s Sphere Lighting. 


Comparing the current prices of these monitors, the difference is only in the range of 18%. The LG 27GL850-B is more expensive by about $74, but is it worth the extra cost?

Best for Competitive Gaming – ASUS TUF VG27AQ


For competitive gaming, function is much more important than in-display looks, and this is where the ASUS TUF Gaming VG27AQ excels. It has incredibly low input lag and a plethora of gaming features which ultimately make it the superior option, especially when taking the price into account. It may not be able to reproduce the same number of colors as the LG 27GL850-B, but its extra OC framerate and overall functionality make it the more suitable option for this type of use.

Best for AAA Title Gaming – LG 27GL850-B

LG 27GL850-B

For triple-A titles, it can be argued that the LG 27GL850-B will provide more immersive visuals; given its larger color gamut, its low motion blur, and faster response times. Additionally, the extra convenience provided with the USB connectivity, paired with its lower power consumption, are always a plus. 

Best for Console GamingTIE

Though current generation consoles will not fully take advantage of the capabilities of these monitors, they can still be connected to them. Neither the ASUS TUF Gaming VG27AQ nor the LG 27GL850-B are ideal for the Playstation 5, as this console does not support 1440p at 120 Hz when connected via HDMI 2.0 – which is quite odd because the Xbox Series X supports 1440p at 120 Hz just fine through HDMI 2.0. Both monitors can downscale 4K to 1440p, but they will be limited to 60 Hz.

Best for General Use – TIE

For general use and productivity, choosing between these two monitors will solely depend on your preferences. The ASUS TUF VG27AQ has a more simplistic and stylish exterior design, better contrast ratios (if you like working or watching movies in the dark), as well as better ergonomic flexibility; while the LG 27GL850-B has a wider color gamut, consumes less energy on average, and has some added connectivity that can be useful. The price difference is not significant, so, depending on what you value most, each monitor can offer in its own unique advantages to your setup.
