34-inch 21:9 curved IPS display

The 34-inch IPS panel uses a 3800R curvature and a 21:9 aspect ratio to deliver an ultrawide viewing area for multitasking professionals. It shows 3440 by 1440 resolution at 60 Hz with 1.07 billion colours and 99 percent sRGB coverage. Anti-glare coating and 178-degree viewing angles keep the image consistent across the broad curve.

Capacity and headroom at 60 Hz

The 60 Hz refresh rate and 5 ms response time handle office suites, code editors and video playback without visible tearing. Colour-critical work benefits from the 1,000:1 contrast ratio and 300 cd/m2 brightness, while HDR10 support adds 1.04 billion colours for compatible content. Fast-paced gaming or high-frame-rate editing will reach the panel's limits quickly.

USB-C with 90 W power delivery

A single USB-C cable carries DisplayPort 1.4 video, data for the integrated USB hub and KVM switch, and up to 90 W of charging for a connected laptop. Two HDMI 2.0 ports provide additional video inputs for secondary devices. This connectivity mix decides whether the monitor fits a one-cable docking workflow.

Questions about this item

Will the 34BQ77QE-B drive a legacy 1080p display over its HDMI 2.0 ports while I keep the curved panel as my main screen?

Yes — both HDMI 2.0 inputs accept 1080p signals up to 60 Hz, so an older monitor can run alongside the 3440 x 1440 panel without extra adapters.

How do I confirm the panel is showing its full 1.07 billion colours and 99 % sRGB coverage after I connect it?

Open the OSD, select the sRGB preset, then run a software colour-space test; the monitor will report 99 % sRGB and 10-bit depth when the USB-C or DisplayPort 1.4 link is active.

Does the box include the USB-C cable that delivers 90 W power and the DisplayPort 1.4 cable for 60 Hz at 3440 x 1440?

The package ships with a USB-C cable rated for 90 W charging and a DisplayPort 1.4 cable; HDMI 2.0 cables are not included and must be purchased separately.
