LG 34UM95-P vs Dell UltraSharp U2715H

If you install LG's software, you will have access to numerous split screen layouts. Similar to stock Windows, you can snap windows to more pre-set arrangements. Support is included for 4 windows (one in each corner), 3 vertical windows, or 3 windows with one dominant window taking up half of the screen (in either horizontal or vertical configuration).

The display on the 34UM95 provides good uniformity in terms of brightness. The image is nearly symmetrical, and only has a noticeable deviation in the top corners. About 75% of the display is within 5% brightness of the middle set point.

As expected with an IPS screen, viewing angles were great. Not major color shifting occurred until 45 degrees - then the image got a bit darker.

Instead of separate buttons, there is a single joystick (located in the middle just below the LG logo) which is used to navigate the menus. It can be pushed in 4 directions (up/down/left/right) and can be pushed in which acts as the selection. It is easy to use, and easy to find even in the dark.

The 21:9 aspect ratio is aimed at productivity users. It fits two programs side-by-side much better than regular wide monitors (16:9), and is pretty much equivalent to a dual monitor layout without adding more displays which requires a powerful GPU. Viewing ultrawide content is fantastic - although not all movies or games make use of the extra space available meaning you could see some vertical black bars on the left and right edges.

Thunderbolt 2 is a new technology that allows for high resolution displays as well as insane data transfer speeds at the same time through a single port.

A single USB 3.0 port allows for very fast data transfer. It is supplemented by 2 USB 2.0 ports which can be used for less data hungry applications such as a keyboard and mouse.

60Hz is the standard refresh rate for monitors, but not all high resolution monitors are capable of 60Hz. Even with the high resolution, 60Hz is still possible providing you have the right cables.

The speakers get loud, and offer good quality audio. There are 2 7W speakers facing downward in the bottom bezel. They won't compete with dedicated speakers, but for most users the benefit of less hardware and cables on the desk will outweigh the performance improvement of dedicated speakers. The monitor is very wide (you could say 'ultrawide'), and already takes up lots of horizontal space on desks leaving less room for speakers anyways.

As expected from an IPS panel, viewing angles are great. Horizontal adjustments don't change the colors much at all. When tilting in the vertical axis, the image can darken slightly.

With 5 USB 3.0 ports (one of which can act as a charger), 2 HDMI ports (with MHL), a DisplayPort and Mini DisplayPort, as well as a DisplayPort out port for daisy chaining multiple screens

It has tilt, swivel, height adjust and can be pivoted 90 degrees in both directions.

The thin plastic bezel (1mm) and small 6mm screen boarder makes this a great screen to put side by side with another to minimise the deadspace between dual monitor setups. Also, an extra DisplayPort out means daisy chaining is possible.

Dell calibrates the U2715H's screen in the factory to very precise measurements, and each monitor will have their own unique calibration report.
