After my review of the LG 40WP95C-W, I promptly switched my setup over to an Ultrawide monitor – and never looked back. It seems more and more people are doing the same thing, because the popularity of Ultrawide monitors in recent years has skyrocketed.

Similarly to a multi-monitor setup, they offer plenty of screen real estate, but unlike a multi-monitor setup, you don’t have the monitor bezels in the middle. This was a massive annoyance to me personally because I’d constantly have to shift my gaze either slightly to the left, or right.

And while ultrawide monitors tend to be more pricier than typical 16:9 aspect ratio monitors, LG Electronics has a few options for the budget-conscious users, one of them being the LG 34WN750-B.

This UWQHD (Ultra Wide Quad High Definition) monitor with a 34” diagonal checks all the boxes when it comes to an affordable ultrawide monitor that you can use for work, and a bit of casual gaming. It’s overall a great monitor for users that want that extra horizontal real estate without spending too much, so let’s jump straight into my review.

What is the LG 34WN750-B? 

Before I get into the monitor’s aesthetics and performance, let’s take a look at the spec sheet. The resolution is UWQHD, which translates into 3440 pixels wide by 1440 pixels high. This is around 35% more horizontal screen real estate when compared to a conventional 16:9 aspect ratio QHD monitor. The 34” panel has a refresh rate of 75Hz, as well as a 5ms grey-to-grey response time and 99% coverage of the sRGB color gamut. 

The monitor also comes with 7W, two-channel speakers built in (they sound a bit tinny though), as well as a stand that lets you adjust height and tilt angle. LG also offers the LG 34WN780-B ultrawide monitor, which has the same panel as the 34WN750-B, but comes with LG’s Ergo Stand that offers more placement versatility. 

With the specs out of the way, let’s take a look at the LG 34WN750-B in a bit more detail – kicking things off with the IPS panel.

Display Panel & Color Accuracy

The 34WN750-B comes with excellent color and image performance, especially when you factor in the price. It covers 99% of the sRGB color space, and comes color calibrated from the factory. Although content creators typically prefer the DCI-P3 color gamut, which offers a wider color range than sRGB, this is a general use monitor, so I can’t complain about LG focusing only on sRGB. 

What I can complain about, though, is LG’s claims of HDR10 content. Even though technically, the LG 34WN750-B does support HDR, the peak 300 nits brightness isn’t enough for a quality HDR experience. If HDR10 is a priority for you, there are better LG monitors out there. To add to this, the contrast ratio is far from impressive, with blacks looking gray in a dark room. 

While you can play with display settings in order to get the image as close to your liking as possible, I wouldn’t recommend the 34WN750-B if you’re doing any kind of color-accurate work. LG’s Nano IPS models might be better suited for that, albeit at a higher price. If, on the other hand, you use it for day-to-day tasks and productivity, the image quality is absolutely fine and in line with most IPS panels. 

Aesthetics and Build Quality

When you look at the 34WN750-B from the outside, the looks are in line with most of LG’s more affordable monitors. The monitor is all black, with slim bezels and an overall minimalist aesthetic. It’s worth mentioning that this is a flat panel rather than a curved monitor, which may be a benefit or a drawback, depending on your personal preference. 

The stand is LG’s curved stand, which does tend to take up plenty of desk space and isn’t exactly a crowd favorite. I much prefer the flat stand on the Dell P3421W. LG, if you’re listening – PLEASE change the base of this stand to something that doesn’t take up half the real estate of my desk!

The 34WN750-B does offer height and tilt adjustment, which is more than most other brands offer in their affordable monitor lineups. Although, if you’re just not a fan of the stand, you can always remove it and use a VESA monitor arm instead.

Overall, I think LG went for a safe approach with the LG 34WN750-B, but that’s not necessarily a bad thing. Despite it’s budget price and obvious cost cutting in some areas, the monitor is built fairly well, feels solid, and is in line with other monitors in this price range. 

Ports and Connectivity

The LG 34WN750-B comes with two full-size USB ports at the back, as well as a DisplayPort port, two HDMI ports and a 3.5mm audio port. There is also a USB downstream port that you’ll use to send the USB device signal from the monitor to your computer. 

What I love about the LG 34WN750-B and the port selection is the placement of the ports themselves. They’re right next to the stand and they’re ever so slightly recessed. This makes it easy to access them at all times, which is not the case with many other monitor models where the ports are on the underside of the chassis.

Unfortunately, this being a value monitor rather than a premium one, it lacks some connectivity features like USB-C, power delivery or Thunderbolt. All of these are nice-to-haves for any monitor, but the same applies as with the panel – at this price, again, I can’t complain. The main selling point is the ultrawide functionality.

Using the LG 34WN750-B

When it comes to actually using this LG ultrawide monitor, I like it quite a bit, but I don’t think it’s perfect for everyone. I have to say I prefer the look of one ultrawide monitor when compared to a dual-monitor setup, and for day-to-day tasks and general productivity, the 34WN750-B is ideal. You can easily have multiple windows open at the same time thanks to the QHD resolution and 21:9 aspect ratio. 

I often have two documents and a website open all side by side when researching, and the large horizontal real estate makes it perfect for multitasking. I’ve used a dual-monitor setup before, and this kind of bezel-free situation is just better. The only downside is the on-screen control software, which is somewhat limited in terms of functionality. You can make better use of all that space if you use a third-party tool for window management. 

What I also liked were the viewing angles, both horizontal and vertical. That, combined with the matte coating on the panel made for a very pleasant viewing experience, which is to be expected with IPS panels. It may not have the best contrast ratio or brightness, but unless you’re doing something that demands color accuracy, such as video or photo editing, you’re not going to have a problem. 

When it comes to gaming on the 34WN750-B, in theory, you can game on it. But whether you should is a completely different story. Most gamers require at least a 1ms response time and a refresh rate of 144Hz or higher when it comes to gaming features. The 34WN750-B has neither, with a grey-to-grey response time of 5ms when set to “Faster” in the menu settings, and a maximum refresh rate of 75Hz, and the input lag isn’t too impressive, either. 

Does that make it bad? Not really, but it’s not going to be ideal if you want to play fast-paced, competitive shooters or racing games. It does however come with AMD FreeSync – which reduces tearing or artifacting. It wouldn’t be my first choice for a gaming monitor, but it’s perfectly suitable for casual, single-player games if you want to wind down at the end of the day.

Pricing & Competitors

Arguably one of the highlights of the monitor is the pricing. LG has managed to keep the price to a reasonable level and push this monitor to market with an MSRP of $499. This is far from budget for a monitor, but when you consider that it’s an in-plane switching panel with a UWQHD resolution and solid build quality, that’s not too expensive. 

Alternatively, you could look at the other LG monitor I mentioned, the 34WN780-B, which has a more ergonomic stand but costs $100 more and offers less value.

I also like the Dell P3421W with almost identical specs, but offers increased functionality with it’s USB-C capability that provides up to 65w of power delivery and outputs an image to the screen at the same time.

Final Verdict

Unless you’re a hardcore gamer that wants the highest refresh rate, lowest response time and input lag possible, or a content creator after high contrast ratio and impeccable accuracy and color depth, the LG 34WN750-B is an excellent monitor to buy. It checks all the boxes from a picture quality and build quality standpoint, and you’ll be hard pressed to find better options for day-to-day use.
