Many users like to have multiple monitors on their desks. Configurations with two and three 16:9 screens are not uncommon. But there’s always that dividing line, and the need to align the images. An ultra or mega-wide monitor solves that problem. There are many 21:9 screens to choose from, but if you truly want the equivalent screen area of two 16:9 panels, 32:9 is the answer.

LG has reduced the footprint requirement just a bit with the UltraGear 45GR75DC. Rather than the typical 49 inches, it has a 45-inch screen. The difference is small, but if you’re tight on space, those few inches might matter. And you can save a few bucks too. 49-inchers with similar quality and specs will set you back $1,000 or more. The 45GR75DC comes out of the gate at $800.

Its cred is large for both productivity and gaming. The 1500R curve lets you work on documents and photos without distortion. Color and contrast make photo editing and web browsing easy tasks. Gaming is a premium experience thanks to the 45GR75DC’s solid 200 Hz refresh rate and top-quality overdrive. And its Adaptive-Sync works flawlessly for AMD and Nvidia platforms. HDMI 2.1 ports support consoles with VRR. And you even get a fancy headphone jack with DTS Headphone:X processing. That’s something you don’t see every day.

Image quality is assured by reasonably accurate out-of-box color and a wide gamut. There is room for improvement in grayscale accuracy, but visually, that was a minor issue. Calibration took the 45GR75DC to reference level. Contrast is very high, and LG has included a field dimming option that took HDR dynamic range to nearly 20,000:1. And it’s very colorful too, with 94% coverage of DCI-P3.

There is little to dislike about the LG UltraGear 45GR75DC. It’ll save you a bit of space and cash over a 49-inch screen and it has everything else needed to qualify for premium status. If you were considering buying two 16:9 monitors, this one might be a better option. Definitely check it out.

    Have to admit, I really do like these Ultra wide monitors. My issues is that I'm partially blind in one eye, so something this wide would be ruined on me.

    Nice to dream though.

    What is it you like about them? I find them downright useless. It's like your squinting the entire time or something.

    I mean it's just a borderless dual 16:9 monitor setup. So if you're accustomed to that setup, it doesn't feel out of place at all. It's also neater since you have one less stand/arm and cables.

    Gaming wise it's more immersive. Downside is a lot of games don't properly support it.

    Aspect ratio does not equal dimensions. Take a look...

    Notice the height.* This thing is literally shorter, by nearly an entire inch. Keep in mind this is a 45inch vs a 32inch, too.

    Sure, the aspect ratio might be the same, but it's literally shorter, by a lot.

    Here is a monitor that I think is nice which is very wide, but also very tall.

    I mean yeah, aspect ratio and dimensions aren't the same considering that the ratio is width/height or more accurately our case horizontal/vertical pixels. Also the dimensions youre looking at are with the base. This LG is equivalent to 2 x 25in 16:9 monitors next to each other, so it's not going to be as tall as a 32in 16:9 or 38in 21:9 which are roughly the same height. The difference between the LG and the two you listed is around 3.5 - 4in in height. So yeah a big difference in absolute height. I'm not going to deny that. My point though is that if you've ever used 2 x 20, 22, 24, etc 16:9 setups (i.e your common office setups) this is basically the the same thing just without the border in the middle. Personally I've never found those setups to be "squinty" for lack of a better word.

    If your preference is for absolute height, I get it. Everyone has their own preferences and it really depends on your use case. Out of curiosity, do you find yourself squinting at anything smaller than than 16in of height in a monitor? Even a 25in 16x9 has a foot of height. Do you find things like phones and other small displays "squinty"?

    The article reviews and gives the discounted price for the LG 45GR75DC but links to it's less capable and cheaper twin, LG 45GR65DC, on Amazon. The difference is the 45GR75DC has USB-C for video input and 90W power delivery.
