Overview

The cocopar HG-4K34C is a 34-inch ultrawide monitor built around a 3440×1440 UWQHD resolution and a 1500R curved VA panel. It targets users who want an immersive widescreen experience without stepping up to a premium flagship price. The non-glare finish keeps reflections down, which makes it a practical choice for both gaming sessions and long office hours.
A standout feature is the USB Type-C port with DP Alt Mode support. It carries video and delivers up to 15W of passthrough charging through a single cable, so laptop and tablet users can keep their desks tidy. The monitor also supports PIP/PBP, letting you view two input sources at once, which is handy for multitasking between a PC and a console.

Compatibility Guide

The monitor offers one DisplayPort 1.4, two HDMI 2.1 (TMDS), and one USB Type-C input. For the full 3440×1440@165Hz experience, you need to connect via DisplayPort or Type-C. Over HDMI, the maximum is 3440×1440@100Hz, with 120Hz available at 2K resolutions or lower.
For console users, PS4/PS5/Xbox support 4K60Hz and up to 120Hz at 2K or below. The Switch 2 supports 4K60Hz and 1080p120Hz. Note that the Switch Lite and Switch 2 cannot use the Type-C video input, so you will need the dock. When connecting a console, the default aspect ratio is 21:9, which can stretch the image; switch the monitor's "Aspect Ratio" setting to "Auto" to display with black bars instead.
The Type-C port requires a device that supports DP Alt Mode. A cable that only carries power will not transmit video, so using the included Type-C cable is recommended. iPad Air and iPad Pro users can use mirror mode or extend the display via Stage Manager on supported models.

Product Info

The cocopar HG-4K34C uses a non-glare VA panel with a 1500R curvature, 350 nits brightness, a 4000:1 contrast ratio, and 120% sRGB color coverage. It supports HDR and displays 10.7 billion colors (10-bit). For Xbox users, enabling HDR10 requires turning on the monitor's HDR setting and checking "Allow YCC 4:2:2" under the console's video mode settings.
In the market, this model is positioned as an entry-to-mid tier ultrawide monitor. It delivers the core specs that matter most—UWQHD resolution, 165Hz refresh, and a curved panel—at a price that undercuts most established brands. The bundled accessories include the monitor, stand, base, Type-C cable, HDMI cable, DP cable, power adapter, Japanese manual, warranty card, and VESA spacers. Note that the accessory set has been updated to include a 2-pin power adapter and two sizes of spacers.

Best Use Cases

  • Laptop users who dock at a desk daily: a single Type-C cable handles video and up to 15W of charging, keeping the setup clean. Not ideal for high-performance laptops that draw more than 15W under load, since charging will be slow.
  • Gamers who want an immersive ultrawide view: the 3440×1440 resolution and 165Hz refresh deliver a wide field of view in supported titles. Avoid if you only use HDMI connections, since that caps the refresh rate at 100Hz.
  • Multitaskers juggling a PC and a console: PIP/PBP lets you display two inputs side by side, so you can watch a stream or guide while gaming. Not for users who need portrait orientation, as the stand's pivot function may not cover that need.

Things to Consider

The refresh rate depends heavily on the connection method. DisplayPort or Type-C is required for 165Hz; HDMI tops out at 3440×1440@100Hz. The default setting may also be 60Hz, so you must change the refresh rate in your device's settings. If your device's specs cannot push 165Hz, the monitor will run at a lower rate.
Type-C video requires DP Alt Mode support on the source device. A power-only cable will not display anything, and the Switch Lite and Switch 2 are not compatible with the Type-C video input. Console users should also expect to adjust the aspect ratio setting, as the default 21:9 mode can stretch the image.
Finally, consider the physical footprint. The monitor measures 810 mm wide, 423 mm high, and 240 mm deep, so it needs a desk with enough depth. Check your setup for clearance before purchasing, especially if you have speakers or other peripherals on the desk.
