Rank #5 in Best Ultrawide Curved Gaming Monitor 2026: 10 Ranked by Spec Sheets
KOORUI 34in 240Hz Curved Gaming Monitor, 3440x1440 VA
Price and rating as shown on Amazon when we collected them. Both change.
The KOORUI 34-inch curved gaming monitor is the fifth entry in this guide to ultrawide curved gaming monitors. It is a 3440 x 1440 VA panel with a 1500R curve, listed at £227.99 and rated 4.3 out of 5 from 197 ratings. Most of what the title promises survives a check against the spec sheet: the title says 240Hz and the Refresh Rate field says 240 Hz; the title says 3440x1440 and the Native Resolution field says 3440x1440.
Two things do not survive. The title's 1ms is a figure the spec sheet never repeats — there is no response time field on the page at all, and the bullets stop at "OD response modes". And while the bullets describe two HDMI 2.1 ports and one DisplayPort 1.4 port, the spec table carries the line "Total Video Out Ports: 1". Everything on this page is taken from the Amazon listing and its customer reviews — we have not measured this monitor ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Bought this on the 8th of July, came with everything I needed, easy to setup too onto a monitor bracket to have two monitors. The monitor has been perfect, no dead pixels or lines well worth the money! You definitely have to tweak the colors or change modes to make it look good as out of the box it can look to bright or over saturated with little sharpness. But once tweaked it looks really good.”
Verified purchase“I'm not a gamer. I'm a video editor. I work with an external broadcast monitor for colour work, so what I needed was screen real-estate. I bought 2 of these for £165 each. I had seen them for as little as 149, but had waited a while and wanted to get it sorted.Couldn't be happier. For that money to get 10 bit panels that are surprisingly colour accurate (to a trained eye only, but that's all I needed) was a pleasant surprise. I use them in a dark studio so brightness is not really a factor when I buy, but these can hold their own opposite a daylight window.As with most 'HDR' labelled monitors at this price point, it's a waste of time, but if you know that going in it's not an issue (Unless you need HDR of course)They are DDC compatible so are controllable by software.Viewing angles do fall off a bit at around 150 degrees, but again, at this price there is very little to complain about. Even comes with an HDMI cable. All told these are 5 star monitors.”

Questions people ask
Does the KOORUI 34-inch monitor really run at 240Hz?
The listing is consistent on this one. The title says 240Hz and the spec sheet's Refresh Rate field says 240 Hz. What the spec sheet does not carry is the 1ms from the title — there is no response time field anywhere on the page.
How many video ports does the KOORUI 34-inch have?
The bullets say two HDMI 2.1 ports and one DisplayPort 1.4 port, and that a DP 1.4 cable is included with 3440x1440 at 240Hz supported. The spec table's own line reads "Total Video Out Ports: 1" (as listed), which does not match that.
What colour coverage does KOORUI claim?
The bullets claim 99% sRGB and 90% DCI-P3 alongside HDR400. The spec sheet's Colour Gamut Value is listed only as "100.0" (as listed), with no unit and no standard named, so it cannot be checked against either figure.
Is the stand adjustable?
The listing says the supplied stand gives 110mm of height adjustment, -5° to 20° tilt and -15° to 15° swivel, and that VESA 75 x 75mm mounting is supported.
How is the KOORUI rated by buyers?
The listing shows 4.3 out of 5 from 197 ratings. The star breakdown shown alongside adds up to 100 (73 five-star, 10 four-star, 3 three-star, 2 two-star and 12 one-star), so the individual review counts are not given.
Anything owners flag?
One reviewer found it too bright and over-saturated out of the box until he changed modes and tweaked the colours, and reported no dead pixels or lines. Another bought two of them at £165 each, below the £227.99 shown on the listing.
