The ASUS TUF Gaming VG27AQGL1A is a 27-inch monitor with a QHD (2560 x 1440) IPS panel and a 170Hz refresh rate. This is the ZAKU II Edition. The 1440p resolution sits between Full HD and 4K, which makes it a common size for PC gaming. Here is what the key specs mean.
Why 27 inches at 1440p
At 27 inches, 2560 x 1440 gives noticeably more detail and desktop space than Full HD, without needing the graphics power that 4K typically demands. For many gaming PCs, it is a practical balance between sharpness and frame rate. IPS panels are known for wide viewing angles and consistent colour from the side.
170Hz and 1ms MPRT
The refresh rate is the number of times the image updates per second. ASUS lists 170Hz as an overclocked rate, with 144Hz also supported. The 1ms figure is MPRT (moving picture response time), a measure of how long each frame is seen; it relates to motion clarity and is not the same as grey-to-grey response. Higher refresh rates only help when your graphics card produces matching frame rates.
G-SYNC Compatible and ELMB SYNC
Variable refresh rate technology matches the screen's updates to the graphics card's output, to avoid tearing and stutter. ASUS lists NVIDIA G-SYNC Compatibility and says it works with Adaptive-Sync, including AMD FreeSync on Radeon cards. NVIDIA support is listed for GeForce GTX 10 series, GTX 16 series, RTX 20 series and newer. ASUS's Extreme Low Motion Blur Sync (ELMB SYNC) lets low-blur backlight strobing run alongside G-SYNC Compatibility, aiming to reduce ghosting and tearing at high frame rates.
HDR, colour and Shadow Boost
The monitor meets the DisplayHDR 400 certification, an entry level of HDR, and ASUS lists 130% sRGB coverage. Shadow Boost brightens dark areas of a scene to reveal detail without over-exposing bright parts.
Eye Care features and stand
ASUS Eye Care includes flicker-free and low blue light technology certified by TÜV Rheinland, according to the listing. The ergonomic stand adjusts for tilt, swivel, pivot and height.
Connections and power
Inputs are one DisplayPort 1.2, two HDMI 2.0 ports and two USB 3.0 ports. The monitor accepts 100-240V, which suits different regions. It measures about 24.2 x 15.9 x 8.5 inches in its box dimensions and weighs 14.6 lb.
Who it suits
It suits PC gamers with a mid-range or better graphics card who want a sharper-than-Full-HD display with a high refresh rate and an adjustable stand.
What to check before you buy
- Graphics card: confirm it can deliver high frame rates at 1440p and has a DisplayPort or HDMI 2.0 output.

- Desk fit: allow for the stand's footprint and the monitor's height.
- HDR expectations: DisplayHDR 400 is a basic tier.
