LG introduced a new generation of its gaming monitors last year, which it brings together called UltraGear. Among them are two models with an ultra-wide 21: 9: 38-inch 38GL950G aspect ratio, and a 34-inch 34GL750, available for a much more affordable price. We will just address the latter in this review after spending a few weeks with it, properly deployed to work, play and test the capabilities of the embedded IPS panel.
The UltraGear 34GL750 is the cheapest monitor on the domestic market with a combination of 34-inch diagonal, IPS panel and 144-Hz refresh rate. Nvidia has certified it as G-Sync compatible, which means that it guarantees completely correct adaptive sync performance when the monitor is paired with GeForce GTX 1000 Series and all RTX. Of course, adaptive sync technology works well on AMD graphics cards as well.
The specifications also highlight HDR10 support, but HDR content is not what you buy it for, since the built-in backlight do not meet the required technical requirements. Therefore, the fore-mentioned support for HDR10 should be interpreted solely in the sense that the UltraGear 34GL750 will be able to receive the HDR10 signal, but its effects will be emulated far beyond what the HDR display seeks to achieve. HDR on PC is widespread anyway and generally quite problematic, so we don’t use even without an LG monitor.
The native resolution of the embedded matrix is 2.560×1.080 pixels. At 34 “diagonal, this results in a pixel density of 82 PPI. Games, movies, series, and other multimedia look satisfyingly sharp, and with the usual sitting distance (70 cm or more), there is no problem with the sharpness of fonts, icons, and other interface elements. This is especially true for anyone who comes with 24 or 27-inch Full HD monitors. the sharpness of the panel of LG’s UltraGear 34GL750 could be insufficient.
The display bracket is designed so that the monitor can be adjusted in height, within 12 inches. We also find a headset holder on the carrier
The sheer width of the screen compared to traditional 16: 9 aspect ratio monitors is beneficial for games and everyday work, especially when using two or three applications at the same time
Thanks to the ultra-wide aspect ratio (21: 9), there is plenty of workspace. It is very easy to work in two applications in parallel, and we often used three of them at the same time (a common combination of Word, Excel and an Internet browser). The sheer width of the screen is particularly useful when working with tools that contain timelines, such as video and audio processing.
Of course, games are worth mentioning as well – titles that natively support the ultra-wide page ratio, and there are really so many today, they fill the field of view perfectly and look extremely appealing. This effect is further enhanced by the slight curvature of the screen. LG does not specify the selected radius of curvature, but it is probably 1800R. However, the curvature is so subtle that the monitor on the front looks completely straight, so there are no noticeable distortions of the image,
By default, the LG UltraGear 34GL750 is set to a fairly high white color of 7.345 K and a brightness of 312.09 cd / m 2 , which will undoubtedly be attractive to many users, but it is still wise to correct for long-term use. To bring the white temperature closer to the desired value of 6,500 K, in OSD, go to Picture Adjust> Color Temp, select the Manual option there, and then select a value of 6,000 K. Why 6,000 K, not the 6,500 K mentioned? For the simple reason that the values selected do not match the actual or measured values, which is a common occurrence for monitors that are not declared professional. When 6,000 K is selected, the actual white temperature is 6,526 K and as such is close to optimal.
When the gamma is set to Mode 2, the measured curve follows the ideal curve by almost a millimeter
In order to lower the screen brightness to near 250 cd / m 2 , which we consider to be optimal for combined day and night work without too much eye strain, in OSD we need to go to Picture Adjust> Brightness and select a value of 85. So with the model tested get a brightness of 251.51 cd / m 2 .
The other picture settings in the Picture Adjust menu need not be changed. Leave the gamma in the Mode 2 setting, since the colorimeter has shown us that it has the value closest to the desired one (2.2) and a truly minimal deviation from the ideal curve, which guarantees the correct display of light and dark details. When Mode 1 is selected, the gamma has a true value of 2.0; the Mode 3 setting is 2.4 and the Mode 4 setting is 2.1, with a noticeably larger curve deviation than the Mode 2 setting.
When the monitor is set up as described, the integrated 8-bit IPS panel gives a natural and distinctly pleasing display, with vibrant colors, satisfyingly refined tone transitions and good dynamics in more complex scenes. The backlight shows no tendency to puncture on any part of the screen, including the edges.
The colorimeter showed us 100% coverage of the sRGB color space, which is more than the declared 99%. Adobe RGB color space has a coverage of 78%, DCI-P3 81%, and NTSC 75%. The screen brightness ranges from 62.4 cd / m 2 (when Brightness is set to 0) to 278.6 cd / m 2 (Brightness 100). Of course, these measurements were made with a white temperature of 6,500 K – if you raise it to a value above 7,000 K, the white color will go from natural to bluish, but the brightness of the image will reach about 320 cd / m 2 . The contrast ratio is around 940: 1 (at a brightness of about 250 cd / m 2 ), which is an expected and quite satisfactory result
When testing color accuracy, we measured an average ∆E of 1.85. All values of ∆E less than 3 are considered acceptable, since the average human eye can no longer distinguish discrepancies in color experience here. For graphic professionals, this limit goes down to 1, but as the UltraGear 34GL750 is not intended for professional editing of videos, graphics and photos, but for gaming and all other forms of home use, we consider it average ∆E commendable. The only color with a slightly higher accuracy difference (∆E 5.25) is a darker shade of cyan, though it is not one that may reduce your enjoyment of playing games or everyday work.
Color uniformity and brightness are two aspects where the LG UltraGear 34GL750 does not knock off its feet. When the same color is stretched across the entire screen, at higher brightness in the upper right corner it has a significant deviation from the lower left corner (∆E 8). However, at lower luminosities, this oscillation is noticeably smaller (∆E 4.9). The backlight is made so that the top third of the screen is between 10 and 21% darker than the center and bottom third (depending on the specific brightness). Fortunately, these anomalies will not be noticeable to the average users targeted by the UltraGear 34GL750.
PERFORMANCE IN GAMES
LG’s gaming monitor performance is excellent. Adaptive synchronization technology takes care of complete motion smoothing and excellent action fluidity. Its operating range is very wide – from 50 to 144 Hz. In other words, as long as your PC can hold between 50 and 144 frames per second in games, you will use adaptive synchronization in full luxury. And since the native panel resolution is a reasonable 2.560×1.080 pixels, you won’t need to have a beastly gamer configuration for this.
Input lag is low – we measured an average of 13.42 milliseconds, with a minimum of 8 ms and a maximum of 18 ms. In terms of responsiveness to the mouse-to-mouse motion-to-screen relationship, this makes it suitable for even eSports professionals.
LG points out that the pixel response time can be as low as 1ms, which is feasible by turning on the 1ms Motion Blur Reduction option. It is a technology that switches backlighting to stroboscopic mode, which really increases the sharpness of moving objects, but with two side effects: the image becomes noticeably less bright (maximum brightness drops to 202.47 cd / m 2 ) and strikingly flickers. Therefore, we suggest not using MBR. Good sharpness of moving objects is also obtained in standard mode by setting the Response Time option (in the Game Adjust menu) to Fast. You can also try Fastest, which in darker scenes results in even greater sharpness of everything that moves, but in brighter ghosting occurs .
At the back are the DisplayPort, two HDMIs, a 3.5mm headphone output and an external power connector.
The OSD uses a four-way joystick , located below the bottom edge of the screen, in the plane of the LG logo. Combined with well-organized and logically arranged menus, adjusting your monitor settings is pretty intuitive. Also useful are the shortcuts assigned to said joystick , which help us quickly access screen brightness, sound volume (in case we use the rear headphone output – no built-in speakers), select inputs (DisplayPort and two HDMIs), and image profiles (Gamer 1, Gamer 2, FPS and RTS – We recommend you use the settings we provided earlier in the description).
With all of this in mind, the LG UltraGear 34GL750 is becoming a great choice for home users. In all important aspects, such as ergonomics, gaming performance and everyday usage, it offers everything the target audience might want, and some of the flaws (color and brightness uniformity) will only be relevant to more advanced users, to whom LG has already targeted other models from this series. As it is the most affordable monitor with incredible combination of features on the market, it is ultimately getting a lot more visibility than expected.
