ASUS ROG Strix XG349C 34-inch Ultrawide Monitor: features and specs

The ASUS ROG Strix XG349C is a 34-inch curved ultrawide gaming monitor with a UWQHD resolution of 3440 x 1440. Its wide panel gives more horizontal room than a standard 16:9 screen, which helps in games that support the format and for work that benefits from side-by-side windows.

What UWQHD means

UWQHD (3440 x 1440) is the ultrawide relative of 1440p. It has the same 1,440 rows of pixels as a regular 1440p screen but is wider, giving a 21:9 shape. In practice you get a sharper picture than Full HD and a wider field of view. Your graphics card will need to drive more pixels than at 1080p, so check it is up to the task at your target frame rate.

180Hz and 1ms

ASUS lists a 180Hz refresh rate, described as overclocking, so it may need to be switched on in the monitor's menu. A higher refresh rate shows more frames per second, which generally makes motion look smoother. The 1ms figure is a grey-to-grey (GTG) response time on the Fast IPS panel. It is a brand figure, measured under favourable conditions.

Motion blur and variable refresh rate

The monitor is G-SYNC Compatible, with variable refresh rate (VRR) on by default. VRR matches the screen's refresh to the frame rate your computer produces, which reduces tearing. ASUS's ELMB SYNC technology lets Extreme Low Motion Blur work together with G-SYNC Compatible, aiming to reduce ghosting and tearing at the same time.

Colour and brightness

ASUS lists 135% sRGB coverage, typical brightness of 360 cd/m², and DisplayHDR 400 certification. Coverage above 100% sRGB means the panel can display a wider range than the sRGB standard. DisplayHDR 400 is the entry level of that HDR certification scheme, so expect a modest HDR lift rather than the punch of a high-end HDR display.

Connections

The XG349C has DisplayPort 1.4, HDMI 2.0, USB-C and a USB 3.0 hub. The USB-C port carries video as a DisplayPort signal and works as a hub, so a compatible laptop can drive the screen and connect a keyboard, mouse or drive through one cable. Check that the USB-C port on your device supports video output.

Size and weight

With its stand, the monitor measures about 16.2 x 32.1 x 11.0 inches (41 x 82 x 28 cm) and weighs about 20.3 lb (9.2 kg). That's a wide screen, so measure your desk.

Who it suits

It suits gamers who want an immersive wide screen, plus people who like a wide workspace for editing, spreadsheets or multiple documents.

What to check before you buy

• Desk space: about 32 inches wide with the stand; also check depth and viewing distance.
• Graphics card: confirm it can output 3440 x 1440 at 180Hz over DisplayPort or HDMI.
• Cables: confirm which cables are in the box, and whether your device needs a different one.
• USB-C: check that your laptop supports video over USB-C.
• Game support: not every game handles ultrawide resolutions well.
• Mounting: if you plan to use an arm, check the VESA pattern in the manual.
