The LG 34GL750 manages to deliver both an immersive image quality and a fluid performance in fast-paced games thanks to its ultra-wide resolution and IPS panel. The price could be a bit lower though and the HDR support is essentially useless.
The LG 34GL750 monitor combines the immersive ultrawide viewing experience with a fast refresh rate and a quick response time speed.
Moreover, it offers lots of features including AMD FreeSync, 1ms Motion Blur Reduction, and HDR (High Dynamic Range).
The LG 34GL750-B is based on an IPS panel with true 8-bit color depth, 99% sRGB gamut, a 300-nit peak brightness, a static contrast ratio of 1,000:1, and 178-degree wide viewing angles.
Now, while it does feature HDR, the support is software-emulated only. In other words, the display doesn’t have any special capabilities that would actually improve the HDR image quality; it can just accept and display the HDR signal.
In fact, the LG 34GL750 doesn’t even qualify for VESA’s entry-level DisplayHDR 400 certification, which requires a wider color gamut (at least 90% DCI-P3) and a higher peak luminance (at least 400-nits).
Basically, you can ignore the HDR spec on this monitor. Some HDR content may look slightly (and arguably) better, but most of the time, you’ll just get washed out colors. What’s more, you can’t use FreeSync and HDR at the same time.
HDR aside, you do get an immersive image quality thanks to the accurate, consistent, and vibrant colors of the IPS panel. The 21:9 aspect ratio further improves the viewing experience as you get a wider field of view in video games and extra horizontal screen space for other use.
2560×1080 resolution isn’t ideal for a 34″ ultrawide monitor as you get a mediocre pixel density of roughly 82 pixels per inch (same as 1080p on 27″ screens). So, the image is more pixelated in comparison to the 3440×1440 models, but these higher resolution ultrawides also cost more and are more demanding to drive.
The LG 34GL750 input lag amounts to only ~4ms at 144Hz, which makes for imperceptible delay while the response time speed of 5ms (GtG) is sufficient to eliminate virtually all trailing of fast-moving objects in fast-paced video games.
There are four response time overdrive options (Off, Normal, Fast, and Faster), but we recommend using ‘Fast’ as ‘Faster’ introduces pixel overshoot (inverse ghosting).
Alternatively, you can use the 1ms Motion Blur Reduction technology, which via backlight strobing (at 120Hz or 144Hz), further upgrades motion clarity. While this feature is active, screen flicker is present (though invisible to the human eye), the maximum brightness is reduced, and FreeSync cannot be used.
AMD FreeSync allows you to synchronize the monitor’s refresh rate with the frame rates of a compatible GPU. The result is a variable refresh rate (VRR) that removes all screen tearing and stuttering within the VRR range, which is 50-144Hz/FPS over DisplayPort and 60-144Hz/FPS over HDMI on this gaming monitor.
Although the LG UltraGear 34GL750 is not certified as G-SYNC compatible by NVIDIA, there are no VRR issues when using FreeSync with compatible NVIDIA cards.
Update: The LG 34GL750 has been added to the list of NVIDIA-certified G-SYNC compatible monitors with the 431.36 WHQL drivers.
The OSD (On-Screen Display) menu of the LG 34GL750 144Hz gaming monitor is quite user-friendly and easy to navigate with thanks to the joystick that’s placed beneath the screen.
You can also download the On-Screen Control application, and adjust all the OSD-related settings there using your mouse/keyboard instead.
Interesting gaming features include Black Stabilizer (increases visibility of objects in the dark), Crosshair (customizable aim points), and pre-calibrated picture settings for FPS and RTS genres plus two customizable Gamer profiles.
Other features include flicker-free backlight, Reader Mode (low-blue light filter), HDR Effect (emulates HDR for non-compatible content), and standard picture adjustments such as contrast, brightness, sharpness, color temperature, and four gamma presets.
Design & Connectivity
The LG 34GL750 features thin bezels and a sturdy design while the ergonomics includes height adjustment up to 120mm, tilt by -5°/20°, and 100x100mm VESA mount compatibility.
Further, the screen has a low-haze 3H matte anti-glare screen treatment which eliminates reflections. Connectivity options include DisplayPort 1.4, two HDMI 2.0 ports, and a headphones jack.
Price & Similar Monitors
The LG 34GL750 price amounts to $550. The LG 34UC79G, which offers the same specifications minus HDR, however, is usually available around $500.
Now, the software-emulated HDR of the 34GL750 isn’t worth the extra $50 over the 34UC79G. If the LG 34GL750 had a wider color gamut and a higher peak brightness, then it would be worth it.
This way, the LG 34UC79G offers better value for the money; it even has a dual-USB hub. In case the pricing is different, you can just go for whichever model is cheaper.
We also recommend you have a look at the AOC CU34G2X which is a 3440×1440 144Hz ultrawide curved gaming monitor with a VA panel.
It offers a significantly better image quality for the same price, but it has a bit slower response time.

Overall, the LG 34GL750 is a great gaming monitor, but it doesn’t really bring anything new to the table. The previous model, the LG 34UC79G, offers just as good image quality and performance at a lower price.
