LG 29UM68-P vs ViewSonic XG2700-4K

Because of the wide aspect ratio, LG offers a built-in picture-in-picture mode (referred to as Split Screen) to display two inputs at once.

The LG 29UM68 uses has great viewing angles, both vertically and horizontally. Color shifting (distortion of colors when viewed at a wide angle) doesn't occur.

The monitor doesn't allow any light of the backlight to get through, which results in no noticeable backlight bleeding: that means dark areas remain dark as intended.

The LG 29UM68 is relatively inexpensive compared to other 21:9 displays and is a great budget choice if you're specifically looking for an ultra-wide display.

The LG 29UM68 is a display with a rather unique 21:9 aspect ratio, which is ultra-wide. The difference with a regular 16:9 display is that there are added pixels on both sides, which increases workspace. It's also ideal to watch movies as most recent movies are filmed in a widescreen aspect ratio. Some games also offer support for 21:9 monitors and will allow you to have a greater field of view.

The IPS-panel used in LG's monitor offers great image quality, especially compared to the more common TN-panels. Contrast is great with a 1000:1 ratio (better blacks), luminosity is excellent, images are vibrant and the color reproduction is great as well. These attributes are all due to the fact that an IPS panel was used.

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.

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.

If needed, the monitor allows you to view from four inputs at once, or to show them picture-on-picture.

Its height, swivel, tilt and orientation can all be freely adjusted, and is attachable to a VESA compatible wall mount or stand.

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.
