LG 38UC99 Front

The LG 38UC99 entered markets as one of the largest monitor’s ever released. LG defeated other manufacturers racing to release their ultrawide monitors with the release of it’s 38UC99, which is considered the world’s first UltraWide Curved monitor with an IPS panel. IPS fixes many problems with viewing angles, so it’s seen as the appropriate choice for a monitor that is going to be curved.

LG states on their website that this monitor is:

“ideal for designers, photographers, producers and other creative professionals who need more room for big ideas.”

Right off the bat, this indicates that the monitor is not aimed at the serious gamer, but rather someone who needs the screen real estate for creative purposes. But thanks to its addition of FreeSync and Motion Blur Reduction modes (MBR), it is obvious LG wanted this to be a monitor that can serve more than one purpose.

In case you need even more space, combining a pair or three of these monitors will not cause any problems, thanks in part to its significantly improved viewing angle.

Image Quality

The LG 38UC99 monitor comes in with a 38″ 21:9 Curved WQHD+ IPS Display (WQHD+ means it is (3840 x 1600) resolution). The monitor features vivid colors, 300 nit of brightness, decent blacks, and limited screen bleed in a dark room.

Some user’s may notice slightly more screen bleed than others, as indicated in the Amazon reviews. This is common for curved panels, which may be more sensitive to shipping damage when compared to flat panels, unfortunately.

Gaming Performance

Although it seems to not be geared towards the pro gamer, this monitor does feature AMD’s FreeSync technology and LG’s 1ms MBR (motion blur reduction) mode. With MBR off, standard screen response times are quoted as being 14ms GTG, or 5ms GTG with FreeSync activated. This is pretty excellent for a monitor this size.

The display has a native refresh ratio of 60Hz, but that can go up to 75Hz with a DisplayPort cable and FreeSync activated. This makes the screen a good contender for a casual gamer who is looking for something they can use for work and play.

Standout Features / Design

It is also obvious that the LG wanted the monitor to be more than just for content creators. It has USB 3.0 and USB C, which effectively allows you to double it as a charging hub – great for laptops with limited ports.

This monitor also comes with a pair of 10-watt speakers, a nice thing to include since many monitors are known for having the worse speakers.

With all of these features, it indicates that LG is aiming for this monitor to be paired with a laptop. It also comes with built-in Bluetooth connectivity, allowing users to pair it with their smartphones or other devices to play wireless search.

View / Ports

There are many ports on the back of this monitor, including a DisplayPort 1.2, two HDMI 2.0 ports, two USB 3.0 ports with fast-charging capability, and a headphone jack.


We can all thank LG for being the leader in making Ultrawide 21:9 monitors mainstream, and they continue to lead with the 38UC99.

Thanks to their efforts, this type of monitor is not a niche product, but one that satisfies a large audience of gamers, working professionals, and casual computer users.

Players, content creators as well as those who simply enjoy having a much better viewing experience now understand the benefits of investing in a large 21:9 display.

With the 38UC99, LG proves to lead once again. The company clearly has another winner here. Although the launch price of $1499 does put the monitor in high-end territory, its specifications and wide range of features, no doubt, make the monitor worth the expensive price tag.

Too wide for some, the LG 38UC99 may prove to be geared more towards content creators rather than gamers. But judging from it’s respectable 5ms lag time with FreeSync enabled, this monitor proves it can be good for both gamers and designers.
