With larger displays being more popular, many companies do not offer premium displays at the 22-inch size. ViewSonic is one of the few that have put together a display monitor that is compact but packs in a lot of features. It uses an IPS-based 21.5-inch display panel with a resolution of 1920x1080 with a modest 250cd/m^2 brightness level and an anti-glare coating. This makes it a great display that can be used is just about any location unlike many of the glossy coating models that can't handle bright light. Color and viewing angles are great. In addition to the display, it also includes a pair of 1.5 Watt speakers which is missing in most display in this size range. Video connectors include HDMI, DVI, and VGA. Sadly, it still only features tilt adjustment for the stand.
When it comes to gaming, it’s all about the display — on-screen performance can make or break the gaming experience. The ASUS VP228H is a standout option with a 1920 x 1080 HD display that features a one-millisecond response time for fluid video playback and a 75Hz refresh rate. HDMI, DVI and VGA ports making for a bevy of connectivity options. The VP228H also features GamePlus technology from ASUS, which gives users the option to enable crosshairs and a game timer. This monitor also has VividPixel technology, which enhances colors and reduces noise around blacks, and Eye Care technology to lower blue light and eliminate any screen flickering in the background, reducing strain on the eyes during longer gaming sessions. Additionally, the VP228H has dual built-in 1.5W speakers for a full sound without the need for an external speaker system.
Registering up to ten simultaneous touch points, the Planar PCT2235 is a brilliant choice for a 22-inch LCD monitor with touchscreen capabilities. It's exceptionally fast, registering each touch with no noticeable lag between a finger press and the response. The 1920 x 1080 resolution display rests on a stand that can be tilted from 15 to 70 degrees and offers 178-degrees of viewing angles for sharp images and vivid colors on every side. The Planar can also be angled back so far that it almost lays flat, which is particularly conducive with the touchscreen capability.
The edge-to-edge surface of the Planar gives the monitor a sleek, all-black design. It includes a built-in USB hub on the rear for easily connecting to an external device. Compliant with Windows 7, 8 and 10, Planar adds the company’s outstanding three-year warranty which includes a free two-day advance monitor replacement. Without the need for drivers to install, plugging the Planar into any PC or Mac computer allows it to start right up as a plug-and-play solution.
It seems that $100 is pretty much the lowest cost one can find for a small monitor and there are lots to choose from. The HP Pavilion 21.5-inch display sets itself apart from other displays because it offers an IPS technology panel. Most low-cost displays tend to use TN panels which while faster have narrow viewing angles and less than stellar color. Brightness is good but not great from its LED edge lighting but it still is sufficient for most users and the ultra slim design and bezel make it so that it can fit into just about any environment. Resolution is typical for monitors of this size at 1920x1080 which allows for full 1080p high definition video. Video connectors include HDMI and VGA. The stand only supports tilt but this is common to most low-cost displays.
Graphics work requires a high level of color support. Typically, this requires more expensive technology such as IPS display panels which provides the best overall color. Sadly, most of the companies that specialized in such displays have moved to only larger displays. This leaves mostly alright but not great choices for those that need a small display. Dell's Professional series uses IPS displays that offer good color but not the color gamut is still limited but better than most. The nice thing is that the stand offers a wide range of adjustments including height, swivel, and pivot that is not generally found on these small displays. It does come with two USB 3.0 and two USB 2.0 ports in addition to the DisplayPort, HDMI and VGA connectors.
