The LG 34GL750-B is a reasonably-priced gaming monitor with attractive specifications and an immersive 34-inch ultrawide IPS screen. It’s a sought after combination in the gaming market, but the lower 2560 x 1080 resolution isn’t attractive due to the resulting lower pixel density. Let’s check out if the LG 34GL750-B can provide a performance that makes up for that limitation.

Design and Features
The LG 34GL750-B is an entry-level option in the brand’s ultrawide product line, but its still an Ultragear monitor that has a unique, and premium design. The monitor has a matte black chassis that’s accented with red streaks in discrete spots so as not to make it too gaudy and out of touch with LG’s branding. The display is bezel-free on three sides, but panel borders will become visible when it is turned on.
The LG 34GL750-B isn’t a modest monitor at all, requiring almost 3 feet of width and around 11 inches of depth on your desk. Its stand is attractive, but it can eat up space that you could otherwise use for your peripherals such as speakers and stream decks. However, this model isn’t too heavy at 18.3 lbs for a 34-inch model.
The curved screen is partly to blame for the LG 34GL750-B’s depth, but the 3800mm radius isn’t as steep as you would think. This characteristic works two ways in the sense that it adds a hint of immersion to the visuals, but it also doesn’t distort the image too much.
Build quality for the LG 34GL750-B is excellent thanks to durable plastics and well-structured design. The device doesn’t have cosmetic imperfections such as uneven gaps or seams, plus the stand doesn’t wobble even if you type heavily. The monitor feels like its more expensive than its actual cost, indicating that the brand’s quality control did an excellent job.
Another characteristic we love about LG’s monitors is they don’t need OSD buttons since most models already include their OnScreen Control feature. You can directly access the monitor’s tools and settings in Windows, so pesky buttons will be a thing of the past. You also get a joystick with this model that is easy to reach and use so navigating the various submenus won’t be as complicated.
The stand included with the LG 34GL750-B that has a base in the shape of plane wings is attractive, but it also has some functionality to it. It offers tilt and height adjustments which frankly, is all you will need for an ultrawide display. You can also opt for VESA mounts which can become necessary due to the depth and width of this part.
Your connectivity options with the LG 34GL750-B is quite limited, but it has everything you will need to utilize its massive display. The panel at the rear includes DisplayPort 1.4 and two HDMI 2.0 slots which can be used for secondary devices like gaming consoles. There is also a 3.5mm jack for headphones, but there are no USB slots for your peripherals.
The older LG 34UM69G is better equipped to be honest since it has a USB-C slot and a pair of decent-sounding speakers. The LG 34GL750-B has none, and we think that the brand could have inserted it somewhere to create better value for the consumers. Gamers will prefer headsets or dedicated headsets, but it would be nice to have a decent pair that you can use when its time to sit back and relax.
Display and Performance
The LG 34GL750-B sports a 34-inch curved IPS panel with a 2560 x 1080 resolution, 144Hz refresh rate, and a 5ms response time that can be boosted to 1ms MBR. The backlight goes up to 300 cd/m2, while the contrast ratio sits at 1000:1 like most IPS panels. this model also advertises HDR10 compatibility, but it doesn’t have the necessary specs to produce considerable improvements.
The primary issue many will have with the LG 34GL750-B is its low pixel density of around 81 PPI which is comparable to a 27-inch 1080p variant. It’s not as crisp as a 1440p model or a smaller 1080p one, but you still get decent clarity and excellent visibility. You also get a bit more room for multitasking which isn’t too bad as well.
The LG 34GL750-B covers 99% of the sRGB gamut which falls within its claimed specifications on the box and official product page. However, its default accuracy could be better since the deltaE average is a bit high at 3.23. Some shades may look incorrectly saturated to trained eyes, but the color temperature is only a few notches below the ideal 6500K point.
You can calibrate the LG 34GL750-B if you have a colorimeter to get a considerably lower dE average of 1.98. however, spending the extra for it is impractical and it may put you in range of a higher model with better imaging performance. We recommend tweaking the screen to your liking instead unless the default setting already looks good to you for gaming.
The LG 34GL750-B posted a 1080:1 contrast at 50% brightness, but some blacks and dark scenes can still look grayish when viewed in the dark. Adjusting the backlight accordingly can help this aspect along with the gamma which sits closer to 2.1 rather than 2.2. This is a common issue with IPS models, but we know of some LG monitors that perform worse in this regard.
Panel uniformity for the LG 34GL750-B could be better since there is a backlight leak on the far side of the screen. There is a noticeable loss in contrast in the affected quadrants, and it can become visible in some murky scenes. Thankfully, not every unit will be affected since there are manufacturing tolerances to consider.
The LG 34GL750-B is great when it comes to pixel responsiveness thanks to its 144Hz refresh rate and a very effective overdrive feature. Setting the latter to its Faster setting cleans up the screen without any visible overshoot. We recommend sticking to this level since anything higher is counterproductive due to the advanced ghosting that will appear on the screen.
The LG 34GL750-B is a FreeSync monitor, but its also certified to be G-Sync compatible by Nvidia. Monitors with this capability offer fantastic value since you will always get to enjoy adaptive sync even if you switch brands. Input lag sits at 10ms at 144Hz so there are no delays even if that isn’t the fastest time we’ve seen.
Thoughts on the LG 34GL750-B
The LG 34GL750-B is a decent monitor if you want a large display with good gamut coverage and responsiveness. The FreeSync/G-Sync compatibility is a huge plus for gamers who plan on keeping their monitors even if they swap GPUs. We like the aesthetics as well since it isn’t too aggressive for a gaming variant, but it could use some slimming down in the dimensions department.
Buying the LG 34GL750-B means you have to live with the lower pixel density which can be an issue if you are used to 1440p or even 4K. The poor factory calibration can also be a negative factor here since not everyone has access to a colorimeter. However, the main problem for this model is its price which rides pretty close the likes of the AOC CU34G2 which already has a QHD screen.
- Excellent Design
- FreeSync/G-Sync Compatible
- Good Color Coverage
- Superb Responsiveness
- Poor Factory Calibration
- Pricey When Compared to Budget QHD Ultrawides
