Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches.

The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10. The percentage of the approximate area, taken by the active part of the screen, to the total front area. The operating temperature shows the safe temperature range (from minimum to maximum), within which the display will function flawlessly. Outside this range it might operate improperly and/or fail entirely. The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen. There are some crucial differences between monitors and TVs that might influence you about which one to get. Monitors could need external speakers to output audio as they mostly don't have one, where as TVs always have speakers. Because of this, users may also require speakers or headphones to enjoy the audio from their connected devices. Iiyama ProLite X4373UHSU-B1: Cheap or Not?Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio.

All three major inputs are catered for, with DVI, DisplayPort and HDMI ports sitting side by side, and there are two conveniently placed USB-A ports on the left-hand side if you want to use it as a USB hub. Connectivity is another area where the NEC EA271U wins out, however, with a forward-looking USB Type-C input and an extra HDMI connector. Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality. The ProLite achieved some tremendous results in our technical tests, hitting a peak brightness of 355cd/m ²with a measured contrast ratio of 1,068:1. While its brightness wasn’t perfectly uniform – it fell off by between 6% and 11% at the edges – that’s still a very respectable result. And the undoubted highlight was an average Delta E of 0.33; any score under one is considered excellent, and even at its very worst this panel scored 0.63.

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC. Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases.

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.The operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. It sets a lower and an upper humidity level for safe operation and is measured in percentage. Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image. Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality. One area where the Iiyama falls behind is its on-screen display (OSD), which is counter-intuitive in almost every way. In particular, the left and right navigation buttons double as up and down buttons depending on the context, so if you’re deep in menus things get confusing. Still, once you get the hang of it, you can switch between standard, game, cinema, scenery and text modes by pressing the Exit button (see what I mean about counter-intuitive?), control the picture-in-picture window and tweak the colour balance. Another niggle is that the display didn’t always recognise when my laptop was resuming from standby; I had to press the input button on the monitor to wake it from its slumber.
