LG UltraGear 27G810A-B / ASUS ROG Swift OLED PG27UCDM

IPS panels offer wide viewing angles and consistent colour; black level stays behind OLED and VA panels.

The small pixel pitch (about 166 ppi) makes text and interface edges look sharper than on 27-inch 1440p monitors.

A small pixel pitch makes text sharper; 4K at 27 inches makes interface elements smaller.

Dual Mode lowers the resolution to Full HD to allow a higher refresh rate; the image is less sharp in that mode.

LG gives this figure for the fastest response time setting; it gives no figure for other settings.

Grey-to-grey transition time; because OLED pixels change much faster than LCD, motion blur depends mostly on the refresh rate.

1000:1 contrast is typical for IPS; blacks can look grey in a dark room.

1,000 cd/m² is a peak reached on a small area of the screen; a full white screen stays much lower. ASUS gives no typical SDR brightness value.

DisplayHDR 400 is VESA’s lowest HDR certification tier; HDR content plays but bright highlights stay limited.

The True Black tier measures OLED’s very low black level; 400 is the minimum peak brightness threshold in the certification test. Dolby Vision support lets compatible sources use scene-by-scene HDR data.

DCI-P3 coverage describes how much of the wide colour space used in films and games can be shown.

ΔE < 2 means factory calibration deviates from target colours by an amount most people cannot see; a calibration report is included.

Variable refresh matches the screen to the graphics card’s frame rate, reducing tearing and stutter.

DSC uses visually lossless compression to fit a 4K 180 Hz signal into DisplayPort 1.4 bandwidth.

The USB ports act as a hub; no USB-C connection for video or charging is listed.

Headphones or external speakers are needed for sound.

Pivot lets the screen be used in portrait; VESA 100 × 100 fits standard monitor arms.

The external adapter keeps the monitor thinner but takes extra space on the desk.

Use the weight without the stand when choosing a monitor arm.

No USB upstream cable is listed.

All inputs support 240 Hz at 4K; variable refresh prevents tearing and stutter as the game frame rate moves between 48 and 240.

USB-C takes video over a single cable and supplies up to 90 W to a laptop. The HDMI 2.1 inputs can be used for 4K 120 Hz on consoles.

KVM moves the keyboard and mouse attached to the monitor between two computers when the input is switched.

A headphone jack or external speakers are needed for audio.

OLED Care includes burn-in prevention functions such as pixel cleaning, screen shift, logo brightness adjustment and taskbar detection. The proximity sensor dims the screen when the user leaves, reducing static image time.

The tripod socket is used to mount accessories such as a camera or light on the stand.

Warranty terms can vary by country.
