USB-C can carry a picture, peripheral data and up to 98W of laptop charging. Some high-power laptops may still need their own adapter.

The USB-C ports do not provide laptop charging, so a separate charger remains necessary.

The matte Glare Free treatment diffuses direct window and lamp reflections far better than many glossy OLED competitors.

The glossy screen makes color look lively but can reflect room lighting, so glare control is worth planning.

Near-black adjustment can reveal hidden dark areas, but too much lifting washes out blacks and some HDR configurations still crush detail.

Dark environments retain strong visual depth and useful shadow definition without washing the scene out.

Sharp 240Hz motion, near-instant response and low lag make it a strong option for fast competitive games. VRR flicker controls can introduce unwanted latency.

The quick OLED response and wide field of view help, but esports-focused players may prefer a smaller 240Hz-or-faster display.

The matte finish is excellent at softening reflections but adds haze and grain compared with glossy QD-OLED rivals. A few users find the texture intrusive.

The glossy finish gives blacks and colors extra depth, especially in controlled lighting.

DisplayPort 2.1, two HDMI 2.1 inputs and USB-C video/charging make this a particularly flexible premium monitor. Missing KVM limits shared-peripheral switching.

HDMI, micro-HDMI and DisplayPort are practical, but the limited video inputs and lack of USB-C video leave less flexibility than some rivals.

The newer Tandem structure aims for better light efficiency, allowing stronger brightness without the same immediate dimming.

Bright scenes can draw substantial power from the expansive OLED panel, adding a small running-cost consideration.

At 240Hz, motion is notably fluid, particularly in fast PC games. Fully exploiting that ceiling requires a PC capable of delivering high frame rates.

144Hz is plenty smooth for many games, yet notably behind the 240Hz alternatives aimed at enthusiasts and competitive players.

The supplied stand adjusts height, swivel, tilt and pivot over a useful range, making ergonomic positioning straightforward.

Smooth height and tilt adjustments help positioning, although swivel and pivot are not uniformly available or practical.

Standard 100 × 100 mm mounting allows an arm or wall mount instead of the bundled stand.

Monitor arms are possible, but the screen’s weight requires a heavy-duty mount and there are differing accounts of adapter requirements.

The high pixel density minimizes subpixel artifacts at normal distance, but slight green or magenta edges remain visible around some close-up text.

Small text, particularly white type on black, can show distracting color fringes for sensitive users.

The rear Core Lighting ring offers pleasant customizable ambient light and screen-synced effects, though broader PC-lighting synchronization is limited.

There is no rear RGB show, which can be a welcome absence for buyers who prefer an understated desk.

PlayStation 5, Xbox and Switch 2 are well served by 4K, HDR and modern HDMI support. Console output tops out below the monitor’s full 240Hz capability.

HDMI connections can accommodate a console alongside a PC, although the limited number of inputs reduces flexibility.

Achieving the full 4K/240Hz experience takes a strong gaming PC and suitable connections, while older DisplayPort hardware may need DSC.

Driving 5120×1440 at high frame rates needs a capable gaming PC; the big display is not a free performance upgrade.

Blacks look exceptionally deep in dark rooms, yet can take on a purple cast under strong ambient light. Some HDR configurations also crush the nearest dark shades.

Deep OLED blacks are one of the screen’s standout strengths, bringing dramatic depth to dark games and movies.

Heavy hardware, a broad panel and the need for a strong monitor arm make relocating or mounting it demanding.

One owner needed to install the Samsung driver before the monitor was recognized when first connected.

The OLED panel exhibits highly even color and illumination without familiar LCD backlight problems.

A reported bug resets HDR brightness to zero after sleep or restart, creating a frustrating repeated setup burden.

The base feels stable in normal use, but light contact can make the whole monitor visibly vibrate.

The immersive 32:9 view is a highlight in supported games, though uneven ultrawide support and high GPU demands are caveats.

The two USB-A ports can serve connected peripherals, and compatible USB-C devices can use the hub through a single cable. Data bandwidth may trade off against maximum video mode.

Color and contrast remain very consistent from the side, making the screen easier to share than many LCD alternatives.

Common adaptive-refresh standards are supported, which is helpful for changing frame rates. Dark-scene flicker means compatibility is not always trouble-free.

Frame-rate fluctuations can cause distracting flashes in dark games. Stabilizing settings may mitigate this, with possible added input lag.

Larger bright scenes retain more output than on earlier OLED designs, although brightness limiting has not disappeared entirely.

Shadow controls can bring hidden dark objects into view, but aggressive settings wash out the contrast that makes OLED attractive.

The QD-OLED layer maintains vivid saturation even as bright HDR elements intensify, keeping colorful scenes energetic.

Full-bandwidth DisplayPort 2.1 is powerful enough for uncompressed 4K/240Hz on compatible hardware. One owner reported intermittent DP signal dropouts that did not occur over HDMI.

With a full UHBR20 connection and compatible GPU, the reviewer verified 4K/240Hz without compression. DSC remains a visually lossless fallback for older links.

There is no integrated KVM switch, so moving one keyboard and mouse between computers is less convenient than on some rivals.

A conventional joystick menu makes key settings accessible and avoids Samsung’s older smart-TV interface. The compact layout and abundance of picture settings still take learning.

Showing two sources at once is a genuinely useful feature, especially across this wide panel, though mode changes can take a moment.

Not every game handles 32:9 correctly; incompatible titles may require fixes or compromise the immersive view.

Xbox users do not get Dolby Vision on this monitor, so the other available HDR formats become the practical options.

Two HDMI 2.1 inputs accommodate modern consoles and other fast video sources, including 4K at 120Hz console modes.

Some multi-device cable arrangements reportedly struggle to maintain the intended resolution and refresh rate together.

Gamma is imperfect before calibration, so exact tonal accuracy may require additional tuning.

HDR offers many detailed settings and two tone-mapping approaches, but dialing in shadows and brightness can become frustrating.

Static mapping better preserves the intended light balance; Active looks livelier but can lift midtones and alter bright detail. Some peak modes crush shadows.

Samsung Display Manager makes the many image and split-screen settings easier to handle than navigating the on-screen menu alone.

Without integrated Tizen apps, this version depends on an attached device for streaming services.

Samsung’s official Windows driver and color profile are useful for proper device recognition and configuration.
