ASUS VG248QG 24-Inch 165Hz G-SYNC Gaming Monitor: specs and who it suits

The ASUS VG248QG is a 24-inch gaming monitor with a Full HD (1920x1080) display, a 165Hz refresh rate and NVIDIA G-SYNC. It is aimed at fast-paced games where smooth motion and quick response matter more than screen size or resolution.

What 165Hz and 0.5ms mean

The refresh rate is how many times per second the screen redraws. A standard monitor does this 60 times a second, so 165Hz shows up to nearly three times as many frames, if your graphics card can produce them. ASUS lists the rate as overclockable, meaning the monitor ships at a lower default and you enable the higher setting in the on-screen menu or graphics driver.

The 0.5ms (GTG) figure is the response time, how quickly a pixel changes from one grey shade to another. Manufacturers measure it under best-case conditions, so it is a brand-rated number rather than a guarantee for every colour change. Lower times typically mean less smearing behind moving objects.

G-SYNC and smoothness

Tearing and stutter occur when the graphics card and the screen are out of step. NVIDIA G-SYNC lets the monitor adapt its refresh rate to the card's output. ASUS says it removes stutter and screen tearing. G-SYNC requires a compatible NVIDIA graphics card, so owners of other cards should check what their hardware supports before relying on it.

Image and game modes

The panel is 24 inches at 1080p, a common pairing that keeps pixel density reasonable and is easy for a graphics card to drive at high frame rates. ASUS quotes viewing angles of 170° horizontal and 160° vertical (CR≧10). The listing also mentions two ASUS tools: GameVisual, which has preset colour modes for different kinds of content, and GamePlus, which adds overlays such as an on-screen crosshair or timer.

ASUS Eye Care is the brand's name for flicker-free backlighting and a blue light filter, and the company says these minimise eye fatigue. Use the on-screen menu to try them, and take regular breaks regardless.

Stand and connections

The stand tilts, swivels and pivots, so the monitor can rotate into portrait orientation, and it adjusts in height. The monitor can also be wall-mounted. Inputs are DisplayPort, HDMI and DVI. As a general rule, the highest refresh rates need DisplayPort, and G-SYNC on this type of monitor is typically used over DisplayPort, so check the manual for which port supports 165Hz.

The listing gives dimensions of 8.3 x 22.1 x 14.1 inches (about 21 x 56 x 36 cm) and a weight of 11.5 lb (about 5.2 kg).

Who it suits

It suits players of competitive shooters, racing and action titles who have an NVIDIA graphics card and want smooth motion on a compact screen. It also works as a second display on a desk where space is limited. Someone who wants a larger or sharper picture for photo editing or watching films may prefer a higher resolution.

What to check before you buy

• Graphics card: confirm it is an NVIDIA card that supports G-SYNC and has a DisplayPort output.
• Cable: make sure you use a cable that carries 165Hz, and check the manual for the right port.
• Frame rates: a high refresh rate only helps if your PC can produce high frame rates.
• Desk space: measure for the width and stand depth.
• Resolution: decide whether 1080p at 24 inches suits you.
• Mounting: check the VESA pattern in the manual for any wall or arm mount.

The short version

• A 24-inch Full HD gaming monitor with a 165Hz (overclockable) refresh rate.
• 0.5ms (GTG) response time as rated by ASUS.
• NVIDIA G-SYNC to reduce stutter and tearing.
• Tilt, swivel, pivot and height adjustment, plus wall-mount capability.
• DisplayPort, HDMI and DVI inputs, with GameVisual and GamePlus tools.
