Alienware AW3226Q / LG UltraGear 27GR93U-B

At 27 inches, 4K means high pixel density; text and detail look very sharp, though Windows usually needs scaling. IPS panels offer wide viewing angles and good colour, but blacks are not as deep as OLED.

Up to 165 refreshes per second. Dell lists both DisplayPort 1.4 and HDMI 2.1 inputs as reaching 165 Hz at 4K; USB-C does not accept video.

Pixel transition specification, not total input lag.

8-bit + FRC imitates 10-bit gradations with rapid dithering; usually invisible to the eye. Hardware calibration writes settings to the monitor’s own memory.

DisplayHDR 400 is the entry tier of HDR certification; without local dimming, the bright-to-dark range of HDR content stays limited. HDR Effect is a picture mode that makes SDR content look more HDR-like.

Matches the refresh rate to a varying frame rate to reduce tearing.

4K/165 Hz requires a graphics card that supports DSC.

HDMI CEC must be enabled for audio return.

PiP shows a second source in a small window; PbP shows two sources side by side.

Flicker-free refers to brightness dimming; reviewers separately saw VRR flicker in dark scenes.

Terms from the US model page; coverage can differ by country.

Portrait use is not supported.

LG notes that 1 ms is only achieved with Game Adjust → Response Time → Faster. 144 Hz requires a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1.

1000:1 is ordinary for IPS: blacks can look grey in a dark room. No local dimming is listed.

Matches the monitor’s refresh to the game’s frame rate, reducing tearing and stutter. According to LG, VRR needs a graphics card with DisplayPort 1.4 (DSC) or HDMI 2.1.

DSC (Display Stream Compression) compresses the 4K 144 Hz signal, which exceeds DisplayPort 1.4 bandwidth, with no visible loss. There is no USB-C input and no built-in speakers are listed.

Black Stabilizer brightens dark areas so opponents in shadow are visible; Crosshair places a fixed aiming point at screen centre. Crosshair is unavailable while FPS Counter is on.

Per LG Canada dimensions, height with stand ranges from 467.7 to 577.7 mm, so about 110 mm of height adjustment. Pivot turns the screen to portrait; swivel is not listed.
