Design & Features

The LG 34WN750-B sports similar aesthetics as most UltraGear monitors. It combines its sleekness with some uncanny gamer-centric vibes. So as not to look too tacky like its competitors, the LG 35WN75C-B monitors have a black matte finish with red steaks in some discrete spots. The monitor has an extra-wide view, and the display is bezel-free on three sides; hence there will be less distraction while gaming or watching movies.

The LG 34WN750-B has a lightweight build as it’s mostly made of plastic. Its weight is reasonable for a 34-inches gaming monitor with an ultrawide view. You should carefully consider your desktop setup features if you’ll be using speakers.

That being said, it needs approximately three feet in width and almost a foot or more in-depth. As such, the LG 34WN750-B is bulkier than most of its competitors in the market.

Though made of plastic, it feels more durable than many budget-friendly models we have handled before. The choice of materials does not compromise the performance of the monitor. It does not exhibit cosmetic defects, nor does its stand wobble unwantedly while gaming.

To access The LG 34WN750-Band OSD, use the joystick under the bezel bottom and, in case you use the monitor as a desktop, use the LG s OnScreen Control feature. The OnScreen Control feature lets you tweak the monitor and its performance without going through pesky buttons fuss. You can quickly and easily adjust common settings amid your gaming session. We wish more manufactures would implementation comparable features in their products.

The LG 34WN750-B stand offers tilt, swivel and height adjustment, meaning that its stand does adversely affect your ergonomics. If you want to save space or intend to have multiple displays in your setup, it can be swapped with VESA or mounted. However, we have issues with its size, though it’s a fair trade-off for a premium monitor that is reliable and stable.

The LG 34WN750-B layout comes with two USB 3.0 ports to connect accessories, two HDMI 2.0 slots together with a Display port 1.4. These ports are enough for two next-gen gaming consoles. It comes with a 3.5mm jack pin for the headset, although it’s not practical since most gamers prefer to use a USB device or the motherboard with a soundcard.

Since most users prefer to use headsets for better immersion work, Th LG 34WN750-B does not have speakers. However, the use of headsets has some setbacks since they are heavy and take up the comfort of relaxation or sitting back while streaming or watching a movie. The lack of speakers is a missed opportunity in our eyes. Having a pair of decently powered speakers can make a massive difference to some buyers.

Display & Performance

The LG 34WN750-B features some advanced specs. It has a 34-inch Nano panel with a 160Hz refresh rate, a 3440X1440 resolution, and, importantly, a 1ms boosted response time. The backlight is spaced at 350 cd/m2. Unlike other Nano IPS models, it has a contrast ratio of 1000:1. And like the LG 34GN850, the LG 34WN750-B is VESA DisplayHDR 400 standard-compliant.

While the 34-inch Ultrawide screens are not the best in class regarding sharpness, they are, nonetheless, remarkable for immersive gaming and productivity. They offer exceptional horizontal space and the right mix of pixel density that yield amazing crispiness and details, making gaming and watching movies a delight. However, you need a beefy GPU to utilize the 160HZ refresh rate that modern titles require.

The LG 34WN750-B covers approximately 100% sRGB and about 80% DCI-P3. Unfortunately, this is slightly lower than what the 34GN850 offers. On the other hand, the default accuracy is much better, with an average delta E of 2.21 compared to the 2.76 the 34GN850 has.

You can use the monitor almost straight out of the box, and only a few minor tweaks are necessary to enjoy some gaming. This makes the monitor a good option for plug-and-play gamers.

However, you can still get excellent performance by honing the monitor’s performance with a colourimeter, whereby you can lower the dE average to about 0.98, which is much better than many expensive monitors. That being said, you should know that the performance averages can vary from unit to unit. This is also an indication that the two monitor models use the same panel but are tuned differently by the manufacturer.

The LG 34WN750-B isn’t perfect either. As far as imaging properties go, its contrast ratio of 967:1 at 60% brightness is its Achilles heel. While the backlight can reach around 455 cd/m2 in HDR mode and 390 cd/m2 in SDR mode, the black luminance the screen produces is less than stellar. Like most IPS panels, the screen does look greyish when used in dark environments. Only screen with VA modules and FALD units perform better.

The LG 34WN750-B has excellent response times when gaming at a 160HZ refresh rate. You do not have to use the Overdrive feature beyond the normal setting, given that the screen is blur-free. You should refrain from setting the Overdrive feature too high, as you run the risk of inducing unnecessary overshoots without benefiting from improved motion handling performance.

LG LG 34WN750-B monitors are compatible with G-sync and FreeSync for NVidia and AMD GPUs. This feature gives you the freedom to choose between the two leading GPU brands. Input lag is about 4ms at the maximum 160 Hz refresh rate. As such, you do not have to worry about delays while gaming.

Thoughts on the LG 34WN750-B

Despite the minor difference in their capabilities, The LG 34WN750-B offers the best choice since it’s expensive compared to the LG 34GN850. If you compare their imaging performance side by side, you won’t be able to tell them apart since the difference is negligible. Most users don’t mind the fact that the monitor packaging doesn’t come with an HDMI cable since other devices that connect to the monitor include one in their packaging.

In today’s market, The LG 34WN750-B is competing with more than the more expensive predecessor. The market is awash with €500 or less ultra-wide monitors with similar performance such as the Gigabyte G34WQC, which comes with a VA and better contrast as well. It offers a great deal, though it’s not the most practical gaming monitor with an ultrawide view that you can get at the moment.

  1. You sure you’ve got the model number right? The specs you’re listing for refresh rate, response time, speakers, G-sync, brightness, HDR are all completely different to any listing I can find for LG for that model number?
