LG 38UC99-W 38-Inch 21:9 Curved UltraWide QHD+ IPS Monitor Review

LG 38UC99-W 38-Inch 21:9 Curved UltraWide QHD+ IPS Monitor Review


Edge cutting screen quality: the WQHD + resolution offer the most impressive color production you will ever find on the market. It will remain top of the line for several years to come. IPS monitors of the last past decade still offer better value than most advanced monitors of this generation.

USB C-type: the addition of this feature testifies to the futuristic design of the LG monitor. You can attain up to 40GBps transfer rates by connecting a Thunderbolt 3 cable to this port. You can also use the port for faster charging of your mobile device.


Split screen: It is the main fail of LG monitor. The display can only be split into two screens managed by two different inputs. Despite the information on LG’s website, the monitor does not feature any split screen patterns. It cannot be split into three screens nor can you have the splits in different width. If you are used to Windows’ split screen capability, then you will understand why the Split Screen 2.0 in this monitor is overrated.

Technical knowledge requirement: It is no doubt that the 38 inch LG monitor comes with exceptional technical features. However, to enjoy the incredible performance of these features, you need to beef up your technical knowledge. The 3840×1600 resolution, for example, only works best with a Thunderbolt 3 USB type C cable. Therefore, you need to understand the specs to look for when choosing your cable. The same applies to HDMI connectors. Unfortunately, suppliers are very thrifty with these specs.

No standard interfaces: the LG monitor is too next gen for interfaces such a DVI, dual-link DVI and VGA. Well, this should not be categorized as a bad thing since it is not LG’s deliberate omission. Any of these connectors cannot achieve the high bit rate requirement of the 3840×1600 resolution screen. They are simply not good enough. Nevertheless, it is mentioned here so that you do not go wondering where the VGA is at.


The LG 38UC99-W 38-Inch 21:9 Curved UltraWide QHD+ IPS Monitor is the king of all monitors available on the market today. It delivers the best view of your design work and high definition movies. Its FreeSync-ed screen also provides a smooth picture rendition for high-performance graphics cards. The two control options give you a choice between sophistication and simplicity with each offering intuitive interface.

While this incredible monitor remains the unrivaled leader, it has gaping flaws that LG should work on before you invest your hard-earned cash in it. The speakers are great for general multimedia applications, but gamers will find the audio quality cheap and irritating. Additionally, the high cost of the cables needed to ensure optimum performance of this monitor tempts most prospective buyers to lobby for a 25% price cut on the machine.

Life is good is the sentence that underscores all LG products. The fact that they are among the leaders in the electronics industry shows that they walk the talk. Still, it seems LG decided to make life better by launching the first 38-inch curved screen; the LG 38UC99-W 38-Inch 21:9 Curved UltraWide QHD+ IPS Monitor. There is way too much to say about this incredible monitor but too little time and space so let’s cut short the introduction.


The LG 38UC99-W monitor has a diagonal panel size of 37.5”, a half inch less than the 38” selling pitch. But this black hat marketing technique sinks into oblivion as you dig deeper into the nitty-gritty of the LG 38UC99-W.

The display panel is of the AH-IPS type, a technology that is recognized for wide viewing angles and high color accuracy. It beats the average color reproduction of standard IPS screens by delivering a color gamut that is above 99%. Due to this, the LG monitor is the best option for professional graphic designers and other experts whose jobs deserve high color rendition.

Screen resolution

The monitor comes with Widescreen Quad plus High definition (QWHD+) screen with a resolution of 3840 x 1600 pixels. The result is an immersive viewing experience and out of the box picture quality. This impressive resolution, however, has a few glitches which are highlighted at the end of this review.

Joystick and onscreen controls

You need at least 15 minutes to learn how to use the joystick, but its performance is better than you can expect from the first impression. It is intuitive and controls everything in the monitor. If you prefer a more sophisticated operation, then you can use the on-screen control. It has all the essential monitor settings such as volume, picture mode presets, dual controller, brightness, and Screen Split.


Game enthusiasts understand the frustrations that result when the monitor’s refresh rates and the graphics card’s frame rates are out of sync. The 38 inch LG monitor eliminates the possibility of stuttering and tearing with a FreeSync technology. It ensures that the rate of frame production is in sync with the monitor’s refresh rate.

Another feature that boosts the gaming experience is the 1ms Motion Blur Reduction. It enhances the monitor’s response time. The effect of having a 2ms response time is a more precise game reaction with reduced blurring.

Connectivity features

The LED backlit 38 inch LG screen comes with several ports; you will have to move the monitor to reach some of them. It has 2 USB 3.0 ports, 1 USB type C ports, and HDMI 2.0 ports and a display port, version 2.1. The two USB 3.0 ports can be used to connect a keyboard or mouse. They are located at the back of the monitor. You can use the Type C port to charge your phone or laptop.

Bluetooth Audio connection

The LG screen uses Bluetooth to connect to your phone, and other Bluetooth enabled devices within range. Unfortunately, this feature could not be turned off in the earlier versions of the monitor. This resulted in irritating popups as other devices tried to connect to it. We hope LG considers sorting this issue in its upcoming firmware upgrade.

Power consumption

LG reports the average rating of this monitor as 70W. However, you can avoid this as a manufacture’s selling pitch and prepare for 120W which is the highest rating.

Possible applications

The best applications for this monitor are graphics and picture quality sensitive programs such as Adobe and CADs. Heavy coders and web designers will also find this monitor more than sufficient. Using this monitor for an MS Word job is underutilizing its capability. The lowest you should go for Office applications is a large spreadsheet. Even then, you will be tempted to split the screen
