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.

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.
7.5 Office

The LG UltraGear 27GR75Q-B is good 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 and decent reflection handling, 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.
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.
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
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
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.
  • 6.9 PC Gaming
  • 6.4 Console Gaming
  • 7.5 Office

Differences Between Sizes And Variants

We tested the 27-inch LG 27GR75Q-B, which is the only size available for this monitor. The full model code may change between regions and retailers, and the results are only valid for this model.

Model Size Resolution Panel Type Refresh Rate
27GR75Q-B 27" 1440p IPS 165Hz

Our unit was manufactured in November 2023; you can see the label here.

Compared To Other Monitors

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.

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.

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.

HP OMEN 27q

The LG 27GR75Q-B and the HP OMEN 27q are both 27-inch budget gaming monitors. The HP is the better monitor for PC gamers, as it has better gaming performance. The HP gets brighter in SDR and HDR, so it's better at overcoming glare. The HP also has significantly better HDR color gamut and volume, making colors more realistic and vivid. However, the LG is the better choice for console gaming, as it can display 4k @ 60Hz signals with the PS5 and HDR with the Xbox Series X|S, which the HP can't do.

Samsung Odyssey G5/G50D S27DG50

The LG 27GR75Q-B and the Samsung Odyssey G5/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.

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.
