Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
The comparison group is almost all 32:9 monitors like the 45GR75DC. The lone 21:9 example is Corsair’s Xeneon Flex, which is of similar resolution and speed. Also here are Samsung’s OLED G9 and LC49G95T, Monoprice’s 43305 and Viotek’s SUW49DA.

END PHOTO ALBUM
The 45GR75DC hums along at 200 Hz with a 5ms panel draw time. Along with a top-shelf overdrive, it maintains excellent motion resolution in fast-moving objects with no visible trail artifacts. I didn’t miss the backlight strobe; it’s simply unnecessary when frame rates stay above 150fps, and the overdrive is this good.
Input lag is about average for the category. The 240 Hz screens have a slight advantage, but the 45GR75DC is close behind with 27ms of total lag. This is quick enough for skilled gamers and casual players alike.
Test Takeaway: Overdrive makes a huge difference in motion quality and the 45GR75DC has an excellent one. Lag is low enough for gamers of all skill levels to have a positive experience. Aiming and movement are as precise as the best gaming monitors I’ve reviewed.
Viewing Angles
The 45GR75DC’s VA panel has great contrast but off-axis image quality isn’t as good as an IPS monitor. Sitting on center, the image is solid from edge to edge with no visible problems. But at 45 degrees to the sides or top, light falls off by 50% and color shifts to red. Sharing is possible if two users sit close enough in a split-screen configuration. This is typical performance when compared to other VA displays.

Screen Uniformity
To learn how we measure screen uniformity, click here.
Though the 45GR75DC comes last in the screen uniformity test, it performs well considering its sheer width. I could see a slight hotspot at the center and in the lower left corner of a black field pattern. This was not visible in actual content. Brighter fields and colors showed no anomalies.

Roland Of Gilead 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.Reply
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.Roland Of Gilead said:Have to admit, I really do like these Ultra wide monitors. -

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...

My monitor ^
Dell S3220DGFPanel Dimensions WxHxD w/base27.9 x 18.6-24.4 x 9.8 inches (709 x 472-620 x 249mm)
LG UltraGear 45GR75DCPanel Dimensions WxHxD w/base42.7 x 17.7-22 x 12.9 inches (1085 x 449-559 x 328mm)
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. -
brandonjclark Here is a monitor that I think is nice which is very wide, but also very tall.Reply

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"? -
StevoReno 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.Reply
