LG 38UC99 37.5 inch curved UltraWide with 3840 x 1600 resolution
Many users find the combination of 34” screen and 3440 x 1440 resolution enticing, offering a nice combination of pixel density and physical screen space. But others find the height in particular (similar to a 27” 16:9 model) a bit restrictive, and want something bigger that maintains a similar ‘UltraWide’ aspect ratio and pixel density. The LG 38UC99 (also known as 38UC99-W or 38UC99-B depending on the colour of the rear) may be just the sort of product these users are interested in. Aesthetically this model is fairly similar to the 34UC98, with the bezels being a bit thicker and the screen itself larger. The stand colour and side trim for the bezels is now a champagne colour rather than silver, too.
The monitor uses a 37.5” AH-IPS panel with 3840 x 1600 resolution (LG LM375QW1), providing a 24:10 (2.4:1) aspect ratio and 2300R (moderate) curve. The screen therefore has a similar (very slightly higher – 110.93 PPI vs. 109.68 PPI) pixel density compared to a 34” 3440 x 1440 UltraWide. It also just over an inch taller and around 3 inches wider, so is quite a physically imposing screen. Users thinking of using this for gaming may be concerned about the ‘unusual’ aspect ratio and resolution. Really, though, there is no need to worry. Games that work correctly in 21:9 should work just fine in 24:10 as well – 21:9 support is drawn with the same brush as support for surround setups and suchlike and isn’t something that is specifically coded as the addition of 21:9 only. Other aspects of the specification which will be of interest include a 1000:1 static contrast ratio, 60Hz refresh rate (52 – 75Hz variable, with Adaptive-Sync) and the use of a very light matte anti-glare screen surface. 178°/178° horizontal/vertical viewing angles are specified with the panel type known for strong viewing angle performance and colour consistency. 10-bit colour is supported (8-bit + FRC dithering) and a flicker-free WLED backlight is used with a specified 99% sRGB coverage. A 5ms grey to grey response time is specified.
Aside from support for AMD FreeSync (Adaptive-Sync) on the monitor, a number of other gaming-oriented features are included. There is DAS (Dynamic Action Sync), which minimises input lag, and the ‘Black Stabilizer’ which artificially boosts dark shades so they appear lighter and more detail is revealed in dark areas. Interestingly the ‘Motion Blur Reduction’ strobe backlight feature is also included, but presumably with some sort of frame multiplication technology used. Such a setting would provide an unacceptable level of flickering at 60Hz and rather a lot at 75Hz. Much like a 60-75Hz CRT monitor, which most of us who are old enough to have used will want to stay well away from. The monitor also includes software that provides the user 14 different split-screen layouts, to enhance multi-tasking potential.
The rear of the monitor is glossy white with the included stand being detachable to make way for 100 x 100mm VESA holes. This stand provides tilt and height adjustment. The ports of the monitor face rearwards in a slightly recessed area to the left of the stand. These include; USB-C, 2 USB 3.0 ports (with fast-charging), DP 1.2a (supports Adaptive-Sync), 2 HDMI 1.4 ports, 3.5mm headphone jack and a DC power input (external power brick). 3840 x 1600 is supported via USB-C or DP at the full native resolution (60Hz), whilst Adaptive-Sync required DP to be used. HDMI will only support the native resolution at 30Hz on this model. Two 10W speakers are integrated into the monitor, firing downwards, which on paper are rather powerful as far as integrated monitor speakers go. The monitor also supports Bluetooth, so you can wirelessly stream audio from phones and other devices straight to the monitor.
Further details can be found on various regional LG websites (including this one, in German). This model is now available in the US for under $1500 and is expected to reach wider availability in regions including the US and UK shortly. We will look to review this model if there is sufficient demand.
