Input Source: To choose an input source from the list of video signals that may be connected to your monitor Resolution: Unless you’re using your monitor exclusively for gaming or watching movies, an ultrawide should have a resolution of 3440×1440 or higher. That’s the same sharpness as a 1440p or “2K” resolution on a non-ultrawide. The text on every 1080p-equivalent (2560×1080) ultrawide we tested was pixelated and hard to read, and on those models the lower resolution negates the extra screen space that makes an ultrawide appealing. 4K- and 5K-equivalent ultrawide monitors aren’t widely available yet. To learn more about connecting your monitor to the PC, refer to the Dell knowledge-base article: How do I connect a monitor to a PC? Display technology and screen curvature: Ultrawide display panels come in two varieties: IPS (in-plane switching) and VA (vertical alignment). IPS is the better all-around choice, with more-consistent color reproduction and solid viewing angles. VA panels have better contrast ratios but suffer from significant color issues when viewed from an angle, which is problematic for a curved display. With few exceptions, 34-inch ultrawide monitors are curved slightly so that they bend inward toward you, making it easier for you to see the whole screen at once. The curve is measured by the radius; the smaller the radius value, the higher the monitor's curve. For example, a 4000R monitor is barely curved, and an 1800R model is more noticeably so. Most ultrawides are 1800R or 1900R.

The 21:9 widescreen ratio is better suited to working on documents side by side than 16:9 displays, and the flatter ratio also means you aren’t faced with the “wall of screen” effect that happens when you sit in front of a 16:9 32in monitor.

Size: Most ultrawide screens measure between 34 and 38 inches diagonally. You can buy a smaller option, but below 34 inches the advantages aren’t noticeable enough to justify the higher price. If you need something smaller, you’re likely to be happier with the resolution and picture quality of a 27-inch 4K monitor or a 24-inch monitor. On the other end of the spectrum, 38-inch ultrawides require a lot of desk space and cost much more than 34-inch models.The IPS panel itself is high quality, with excellent colour accuracy in the default mode: an average Delta E of 0.29 and a maximum of 0.95 are effectively perfect. In that mode, it covers 100% of the sRGB gamut with a 124% volume and 88% of the DCI-P3 space. Brightness consistency is even across the screen too, although it inevitably drops off (by around 10%) at the far edges.
