LG 38UC99 review: 4K UltraWide

LG brings 21:9 UltraWide to another level



The LG 38UC99 is a phenomenal monitor. The width of the screen means you have the work space of two full hd-monitors, while the vertical resolution is a lot higher. Fans of 16:10 1920x1200 monitors should realize that with this monitor they essentially have two 1920x1600 monitors in front of them: ideal for productivity applications. If you use a lot of different programs, photo- and video editing, spreadsheets and documents, dtp, web design and programming or other applications that can use the extra screen space on a daily basis, this is the monitor you want. The combination of the huge number of pixels without the need for scaling is a feature unique to this monitor at the time of writing. The monitor is usable for gaming, but that is not its primary purpose – if you only want to play video games and you have a budget that allows you to shop in this price range, you would be better off with a model that has less pixels but a higher refresh rate.

The image quality is without a doubt very good. We had hoped for a slightly better result, especially because LG claims that the monitor has a factory calibration, but even without calibrating it yourself you can definitely work with it. We would advise graphics professionals to calibrate the monitor, but for this also goes: if your first priority is absolute colour accuracy, you might want to choose another monitor in this price range that has slightly less pixels but a wider colour space.

In terms of connectivity the 38UC99 has everything you could wish for, although we would have liked to see more usb host-ports as well as a mini-displayport. There are not a lot of devices that support usb type-c, although this is increasing dramatically – in any case, you are set for the future with this monitor.

The inability to rotate as well as the on-screen menu that is not that intuitive are some points of criticism, although that does not diminish the fact that we cannot think of any other ‘ultimate’ monitors for those that need a lot of work space at the time of writing. For that reason we award the 38UC99 with a Hardware.Info Ultimate Product award.
