SpecPicks Verdict

SpecPicks scored LG 34WN80C-B UltraWide Monitor 34” 21:9 Curved WQHD IPS Display using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming monitors category. LG's gaming monitors lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for gaming monitors of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

What resolution is the LG 34WN80C-B?

It runs WQHD 3440 x 1440 across a 34-inch 21:9 curved IPS panel, which is about 35 percent wider than a standard 2560 x 1440 display.

Will one USB-C cable charge my laptop and drive the display?

Yes. The USB Type-C port supports 60W power delivery alongside video and data, so a compatible laptop charges over the same cable that carries the picture.

Is this monitor good enough for gaming?

Response time is rated at 5ms, which suits casual and story-driven gaming. Competitive players who need 1ms panels should look at dedicated gaming ultrawides.

How accurate is the color for photo and design work?

The IPS panel covers 99 percent of the sRGB gamut with 178-degree viewing angles. It is sRGB-focused, so check the listing if your workflow requires DCI-P3 or Adobe RGB.
