Desktop Displays
Information Systems & Computing (ISC) recommended a 17-inch cathode ray tube (CRT) monitor as the desktop standard for nine years. Beginning with the 2007-2008 desktop recommendations, the display standard was revised to a 19-inch liquid crystal display (LCD) and, for the 2022-2023 desktop recommendations forward, a 24-inch display is specified. While ISC believes that the 24-inch LCD standard will suit the needs of most users, it's important to be aware of other considerations that may influence your specific requirements.
ISC recommends purchasing displays that specify a 16ms or lower response time (gray-to-gray) and using a digital video input, such as DisplayPort, Thunderbolt, USB-C, or HDMI, to reduce the effects of input lag—typically appearing as “smearing” or “ghosting” when on-screen items are in motion. Most users are also well served by monitors using in-plane switching (IPS) display technology. IPS panels are often regarded as having significantly better color reproduction capabilities and viewing angles than competing technologies, and they are suitable for office use and for visual media where accuracy is paramount.
ISC strongly recommends purchasing displays toward the higher end of the market, especially since it is common practice at the University to retain the same display for two system life cycles. The preference for displays is WUXGA resolution or above (with an absolute minimum of Full HD), though higher resolutions such as QHD are appropriate for some users. Generally speaking, modern high-resolution displays are also associated with visual quality improvements, such as high dynamic range (HDR) color and faster refresh rates, which might be suitable for visual media production and playback. ISC has had good experiences with Dell's UltraSharp, Professional, and Pro Plus displays and with Lenovo's ThinkVision displays. Displays from LG and Viewsonic also have a good reputation at Penn.
Notebook Displays
Notebook displays are necessarily constrained by size, with about 90% being in the 13-inch to 16-inch range. ISC believes that resolution is important, and specifies a minimum of WUXGA for all but value systems. Brightness is also relevant for notebook displays, and ISC recommends a minimum of 300 nits for both mid-weight and lightweight systems. In general, there is more variance in notebook displays available from Dell and Lenovo than there is in those from Apple and Microsoft.
