Pros
Pro Superb color accuracy and picture reproduction
ViewSonic takes color accuracy seriously with this monitor, as it is comes calibrated out of the box. The monitor uses a 10-bit panel and can display 99% of the sRGB color range. On top of that, it has almost no issues with screen uniformity, color accuracy and gamut. This makes it great for editing photos, videos and other types of work that require accurate colors.
Pro Plenty of input options
ViewSonic has equipped this monitor with very generous input options. It has three HDMI 2.0, one DisplayPort and one DisplayPort mini. It also has four USB 3.0 ports, two of which are on the right side of the monitor for easy access.
Pro Allows you to view from four inputs at once

Pro Easily adjustable
Its height, swivel, tilt and orientation can all be freely adjusted, and is attachable to a VESA compatible wall mount or stand.
Pro Excellent input lag, decent pixel response time
Input lag is almost non-existent on this screen, at only 9.9ms if the “Extreme” input mode is selected. This makes this monitor among the fastest in the market. Since it uses a slower IPS panel (compared to TN panels), the pixel response time measures just 5ms, which isn’t the best, but is good for most situations.

The LG 38UC99-W displays beautiful pictures, with deep and rich blacks, vibrant and accurate colors, and good-looking intermediate tones. Despite the fact that the monitor's native contrast ratio is only 1000:1, the dark scenes look deep and intense as the backlight of the 38UC99-W can drop below the brightness level of 0.15 nits, which only the best monitors can do. Colors pop and look vivid, as the 38UC99-W can sustain its brightness above the 300 nits mark. The mid-tones look lifelike thanks to the monitor's near perfect gamma value, which is only 1.3% off from the ideal value.
Moreover, the monitor's color inaccuracies can't be seen by the human eye because it only has an average color error dE of 2.12.
Cons
Con Gaming presets do not bring any real improvements to the visual quality
Although there are a lot of gaming presets to choose on the monitor, they are either too bright or dark and do not bring any real improvements on the visual qualities.
Con Very expensive
For the same price as this monitor, you can buy three decent 27-inch ultrawide monitors.
Con Bluetooth indicator is inconvenient
The monitor's Bluetooth indicator occupies the on-screen workspace. Unfortunately, there is no way to remove the indicator while using the Bluetooth speaker option.
Con Has an external power brick
The external power supply unit of the LG 38UC99-W might cause inconvenience especially if you want to mount this monitor on a wall since the PSU is quite bulky.
Con Wobbly
The stand isn't rigid, so you might observe some minor wobbling if your work desk is flimsy,
Con OSD is quite messy
The on-screen-display of the LG 38UC99-W does not have any programmable shortcut keys and is quite hard to navigate.
For example, to enable or disable the motion blur reduction feature, you’ll need to press more than 15 keys because the menu goes very deep.
Con Unsuitable for gaming
Gaming just doesn't feel responsive because of the monitor's massive input lag.
