LG UltraWide 34U65ZA-B 34"

Manufacturer: LG

The LG UltraWide 34U65ZA-B is a 34-inch curved ultrawide monitor built around an IPS panel with LED backlighting. It targets users who need broad horizontal screen real estate alongside accurate color reproduction, offering 99% sRGB coverage and support for up to 1.07 billion display colors. The matte, anti-glare panel surface helps reduce reflections in typical office or studio lighting conditions.

The display outputs a 3440x1440 resolution at 60Hz with a pixel density of 109 ppi and a 5ms response time, while wide viewing angles of 178 degrees in both directions are supported. Connectivity options include two HDMI ports, one DisplayPort 1.4 output, USB Type-C, four USB ports, and a 3.5mm audio jack, with Ethernet also built in. The stand supports tilt, swivel, height adjustment, and portrait rotation, and the monitor is VESA-mount compatible. Stereo speakers and Picture-in-Picture functionality are included, and operating power consumption is rated at 29W.

Pros

The stand supports tilt, swivel, height adjustment, and portrait rotation, offering meaningful ergonomic flexibility for different workstation setups
Wired Ethernet connectivity is built in, removing the need for an external adapter in network-dependent environments
With 99% sRGB coverage, 1.07 billion display colors, and support for color calibration, the panel is well-equipped for color-sensitive workflows
Four USB ports plus USB Type-C provide a reasonable number of peripheral connections directly from the monitor
Picture-in-Picture support allows content from two sources to be viewed on screen at the same time
VESA mount compatibility gives users the option to use third-party arms or wall mounts instead of the included stand

Cons

The 60Hz refresh rate and absence of any adaptive synchronization technology make this monitor a poor fit for fast-paced or motion-sensitive tasks
A 5ms response time is relatively slow for motion-heavy content, which may result in noticeable blur during fast sequences
Thunderbolt is not supported, limiting high-bandwidth single-cable workflows for users who rely on that interface
Wi-Fi is not available, so network connectivity depends entirely on a physical Ethernet connection
No ambient light sensor means the display cannot automatically adjust brightness based on room lighting conditions
There is no remote control included, so all adjustments must be made directly on the monitor itself

Who is this for?

This monitor is a solid fit for users engaged in color-sensitive workflows such as graphic design, photo editing, or digital content creation, given its 99% sRGB coverage, color calibration support, and 1.07 billion color depth. The wide 34-inch ultrawide curved panel also suits professionals who benefit from extended horizontal workspace, such as those working across multiple documents or applications simultaneously. Additionally, the built-in Ethernet, four USB ports, USB Type-C, and flexible stand adjustments make it a practical choice for structured office or studio desk setups where connectivity and ergonomics matter.

Who is this NOT for?

Users looking for a monitor for fast-paced gaming or motion-heavy content will find this display limiting, as its 60Hz refresh rate and 5ms response time are not well-suited for smooth, responsive visuals in those scenarios, and the complete absence of adaptive synchronization further reduces its appeal in that context. The lack of Thunderbolt support also makes it a poor match for high-bandwidth single-cable workflows common among certain creative professionals using MacBooks or similar devices. Users who prefer a wireless desk setup will also be at a disadvantage, as Wi-Fi is not available and network access depends entirely on a wired Ethernet connection.
