LG UltraGear 27G810A-B / LG UltraGear OLED 27GS95QE-B

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

Although sold in the 27-inch class, the viewable diagonal is 26.5 inches. OLED lights each pixel itself, so there is no backlight bleed.

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.

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

LG quotes 275 nits for a full-white screen (100% average picture level); small bright areas can be brighter.

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

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

A printed calibration report is included. Hardware calibration uses LG Calibration Studio with a compatible meter.

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.

GtG is the time a pixel takes to change from one grey level to another; lower values reduce motion blur.

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

DSC compression helps carry QHD at 240 Hz over DisplayPort 1.4. There is no USB-C video input.
