The LG 27GR75Q-B is a 1440p 27-inch budget gaming monitor. It joins a number of other monitors in the 27-inch budget gaming segment, like the Dell G2724D. It's a lower-cost entry in LG's UltraGear gaming lineup and is less expensive than other UltraGear monitors like the LG 27GP850-B/27GP83B-B. However, it still provides a number of gaming features, like a 165Hz refresh rate and FreeSync and G-SYNC compatibility. To reach its budget price, it doesn't have many added features, like USB. However, it has some of LG's gaming-specific features, like a black stabilizer, crosshairs, and an FPS counter.

How We Test Monitors

We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.

Our Verdict

6.9
PC Gaming 

The LG 27GR75Q-B is okay for PC gaming. It has FreeSync and G-SYNC compatibility to reduce screen tearing, and its 165Hz refresh rate is good enough for most gamers but not competitive gaming. It has low input lag for a responsive feel and a fast response time at high refresh rates, but it's worse at lower refresh rates as there's blur. However, its mediocre contrast causes deep blacks to appear gray in a dark room, and highlights don't pop in HDR.

Pros
  • Fast response time at high refresh rates.
  • Low input lag.
  • Supports FreeSync and is G-SYNC compatible.
Cons
  • Highlights don't pop.
  • Low contrast makes blacks look gray in dark rooms.
  • More blur and inverse ghosting at 60Hz.
6.4
Console Gaming 

The LG 27GR75Q-B isn't bad for console gaming. It has a fast response time at 120Hz, but it's slower at 60Hz, as there's more blur and inverse ghosting. It also can't take full advantage of the PS5 and Xbox Series X|S due to the lack of HDMI 2.1 bandwidth, but it still works with most signals with either console. It also has low input lag for a responsive feel while gaming. Unfortunately, though, it has limited picture quality as blacks look gray in the dark, and colors aren't vivid.

Pros
  • Fast response time at high refresh rates.
  • Low input lag.
Cons
  • Can't take full advantage of consoles.
  • Low contrast makes blacks look gray in dark rooms.
  • More blur and inverse ghosting at 60Hz.
7.4
Office 

The LG UltraGear 27GR75Q-B is decent for office use. It has good text clarity, and its 27-inch screen is large enough to open two windows side by side. It also has good brightness, so it can overcome glare unless you're in a very bright environment. However, it can't swivel, so sharing your work with a colleague is more difficult.

Pros
  • Bright enough to fight glare in most well-lit rooms.
  • Wide viewing angles.
  • Good text and image clarity.
Cons
  • Doesn't swivel.
  • No USB hub.
  • Distracting reflections in really bright rooms.

6.9
Editing 

The LG 27GR75Q-B is okay for content creation. It has good text clarity, and you can open two windows side by side due to its large 27-inch screen. However, it only has satisfactory color accuracy before calibration, and you need to calibrate it for the most accurate colors. Additionally, it displays a limited range of HDR colors, so it can't display some colors if you're editing photos or videos in a wider gamut. It also can't swivel, so sharing your screen with colleagues is more difficult.

Pros
  • Bright enough to fight glare in most well-lit rooms.
  • Wide viewing angles.
  • Good text and image clarity.
Cons
  • Doesn't swivel.
  • No USB hub.
  • Needs full calibration for most accurate colors.
  • Distracting reflections in really bright rooms.

6.7
Brightness 

The LG 27GR75Q-B has okay brightness. While it's bright enough to fight glare in most well-lit rooms, it can't overcome glare in really bright environments. It also doesn't make highlights pop in HDR.

Pros
  • Bright enough to fight glare in most well-lit rooms.
Cons
  • Highlights don't pop.
7.7
Response Time 

The LG 27GR75Q-B has a good response time. Its response time is fast at high refresh rates, but there's more motion blur at lower refresh rates.

Pros
  • Fast response time at high refresh rates.
Cons
  • More blur and inverse ghosting at 60Hz.
4.6
HDR Picture 

The LG 27GR75Q-B is terrible for HDR. It has a low contrast ratio, so blacks look gray in dark rooms, and it lacks a local dimming feature. It also fails to make colors look vivid.

Pros
None
Cons
  • Low contrast makes blacks look gray in dark rooms.
  • Lack of local dimming feature.
6.6
SDR Picture 

The LG 27GR75Q-B has okay picture quality in SDR. Its main strength is that it displays a wide range of colors, but blacks look gray in dark rooms due to its low contrast.

Pros
None
Cons
  • Low contrast makes blacks look gray in dark rooms.
7.7
Color Accuracy 

The LG 27GR75Q-B has good color accuracy. However, you need to calibrate it for the best accuracy as colors are oversaturated before calibration.

Pros
  • Good gray uniformity.
Cons
  • Needs full calibration for most accurate colors.

    Popular Monitor Comparisons

    The LG 27GR75Q-B is a decent budget gaming monitor. Its 165Hz refresh rate is good enough for most entry-level gamers, and fast-moving objects look crisp. However, there are better gaming choices you can get for a low cost, like the LG 27GP850-B/27GP83B-B, which has a higher max refresh rate of 180Hz and USB ports but costs more. Even the Dell G2724D is another good choice as it gets brighter than the 27GR75Q-B and has more consistent motion handling.

    For more options, check out our recommendations for the best budget and cheap monitors, the best 1440p gaming monitors, and the best 27-inch gaming monitors.

    Samsung Odyssey G50D S27DG50

    The LG 27GR75Q-B and the Samsung Odyssey G50D S27DG50 are 1440p 27-inch gaming monitors. Both monitors are similar, and you may prefer to get whichever is less expensive. However, the Samsung is better if you plan to use the monitor in a bright room, as it gets much brighter.

    LG 27GP850-B/27GP83B-B

    The LG 27GR75Q-B and the LG 27GP850-B/27GP83B-B are 27-inch budget gaming monitors. However, the 27GP850-B/27GP83B-B performs better and is the better choice for most people. The 27GP850-B/27GP83B-B is better at overcoming glare, has a higher refresh rate, and displays fast-moving objects more crisply.

    LG 27GN800-B

    The LG 27GR75Q-B is a newer model than the LG 27GN800-B, and both are entry-level 1440p gaming options. The newer 27GR75Q-B improves in some areas, like the fact that it comes with a more ergonomic stand, but overall, both monitors are very similar.

    Dell G2724D

    The LG 27GR75Q-B and the Dell G2724D are both 27-inch budget gaming monitors. However, the Dell is the better choice for most people. The Dell gets far brighter in HDR and SDR and is better at overcoming glare. The Dell also has better motion handling, so fast-moving objects look more crisp. Finally, the Dell supports VRR with the PS5, and the LG doesn't.

    This monitor has a gamer-oriented design with a dark gray plastic body. Though the monitor body has a simple aesthetic from the front, both the appearance of the tripod-based stand and the back of the monitor make it clear that LG designed this monitor for gaming.

    Build Quality

    The build quality is good. Though the stand is mostly plastic, it's solid, and there's almost no creaking. The monitor body is well constructed, and the bottom bezel is flush across the entire bottom of the screen.

    The ergonomics are decent. It has a good, smooth height adjustment system, so you can easily place it in your preferred position for a long gaming session. However, it can't swivel, so it's more difficult to share your screen with another person while co-op gaming or working. The stand features a hook for cable management.

    The SDR brightness is good. It remains consistent with different content and gets bright enough to fight glare in a well-lit room. However, it has more trouble overcoming glare in brighter environments, particularly if the sun shines directly on the screen. These results are from after calibration in the 'Gamer 1' Game Mode, which is the picture mode setting, with the Brightness at its max and DFC turned off. If you're looking for a monitor that gets brighter, check out the Samsung Odyssey G5/G50D S27DG50.

    The HDR brightness is mediocre. It doesn't get bright enough for highlights to pop against the rest of the image. Additionally, it has a slow roll-off towards its peak brightness, so highlights don't get the brightest they could. These results are in the 'Gamer 1' Game Mode in HDR with the Brightness at its max.

    The accuracy before calibration is decent. Colors are relatively accurate but significantly oversaturated because the monitor lacks an sRGB mode to control the color gamut. Also, the color temperature is too cold, though the white balance is good. Finally, dark scenes are too dark, and bright scenes are too bright. There aren't any locked-out settings when using the 'Gamer 1' Game Mode.

    The LG 27GR75Q-B.AUS has good motion handling across its VRR range. The 'Normal' Response Time overdrive setting provides the consistently best performance, but it has more motion blur at lower refresh rates. The 'Faster' overdrive has such a high CAD that it passes the limits of the chart, and you can see it in an alternative chart here.

    The CAD at 120Hz is good. Unlike at its max refresh rate, the 'Normal' overdrive setting provides the best motion handling, so you may have to switch the setting if you change games or sources. It has the quickest response time, but there's still some blur, and 'Fast' and 'Faster' have noticeable inverse ghosting.

    The CAD at 60Hz is decent. There's noticeable blur and even inverse ghosting with the 'Normal' overdrive setting. If that bothers you, turning it off results in no overshoot, but it has more blur than using the 'Normal' setting.
