ASUS VP227HE 21.5-Inch Full HD 75Hz Monitor: features and who it suits

The ASUS VP227HE is a 21.5-inch Full HD monitor with a 75Hz refresh rate and a frameless look. It suits a home office, a study desk or a second screen, and it connects through HDMI or VGA. Here is what its listed specs mean for everyday use.

Screen size and resolution

The panel measures about 21.45 inches diagonally and runs at 1920 x 1080 pixels, known as Full HD. At this size, Full HD gives a reasonably sharp picture for documents, browsing and video. ASUS lists a 178-degree wide viewing angle, which generally means colours and brightness hold up when you look at the screen from the side.

What 75Hz and Adaptive-Sync do

Refresh rate is the number of times the screen updates each second. Many basic monitors run at 60Hz, so 75Hz is slightly smoother for scrolling and moving images. ASUS also lists Adaptive-Sync/FreeSync, a technology that lets the monitor match its refresh rate to the frame rate of a compatible graphics card. This reduces tearing, where parts of two frames appear at once. It needs a compatible graphics card and a suitable connection, so check your setup.

Contrast ratio

The listing gives a contrast ratio of 3,000:1. Contrast ratio compares the brightest white with the darkest black a screen can show, and a higher figure typically means deeper blacks in a dim room. It is a manufacturer specification and is measured under particular conditions.

Eye Care features

ASUS says the monitor uses flicker-free and low blue light technologies, certified by TÜV Rheinland. Flicker-free backlighting avoids the rapid brightness changes that some screens use to dim themselves. Low blue light modes shift the colour balance warmer. These are display settings, and the listing makes no further claims.

Connections

The ports are HDMI (version 1.4) and VGA. HDMI carries digital video and works with most current laptops, desktops and consoles. VGA is an older analogue connection found on older computers and projectors. There is no DisplayPort or USB-C input listed, so check that your device has an HDMI or VGA output, or use an adapter.

Design and mounting

The frameless design keeps the borders thin, which helps with side-by-side setups. The stand tilts, and the monitor is wall mountable. The listed size is 8.0 x 19.4 x 14.0 inches and the weight is 6.1 lb (about 2.8 kg). The stand tilts only, so there is no height adjustment listed; if you need that, a wall mount or monitor arm with a compatible VESA pattern may help. Check the VESA size in the manual.

In the box

ASUS lists an HDMI cable, a power cord, a quick start guide and a warranty card.

Who it suits

The VP227HE suits everyday computing: email, documents, streaming and light gaming at 1080p. It is less suited to people who need a higher resolution or a larger workspace, or to colour-critical work.

What to check before you buy

• Your ports: confirm your computer has HDMI or VGA output.
• Desk space: measure the width and depth, including the stand.
• Height: only tilt is listed, so check whether the screen height suits your seating.
• Adaptive-Sync: check that your graphics card supports it, if that matters to you.
• Wall mounting: check the VESA pattern against the mount you plan to use.
• Warranty: read the warranty terms for your region.
