KTC M27T6S Review: A Budget Mini-LED Powerhouse?

First, a confession. I'm not much of a mini-LED fan. You might even call me a dimming-zone snob. I've never found LCD panels with full-array local dimming terribly convincing, and of late it's been hard to argue with the latest OLED gaming monitors. So, it's definitely a surprise to discover that one of, if not the best mini-LED monitor I've yet seen is this new budget-priced model, the KTC M27T6S.

Am I giving away too much, too soon? Perhaps. But the fact that I came into this review pretty sceptical of LCD monitors with local dimming hopefully means that when I say I was impressed by the KTC M27T6S, it carries a bit more weight. This monitor does the local dimming thing remarkably well. Does it do it well enough to convert me to mini-LED technology? Now there's a question.

We'll answer that momentarily, but first let's cover the basics. This is a 27-inch model with a 2,560 by 1,440 native resolution. For gaming, that's just great. 4K is dandy in theory, but at just $290, this is not a premium-priced monitor and it's implausible to think the KTC M27T6S will be paired with the kind of $1,000 GPU you need to really make the most of 4K.

Key Specifications of the KTC M27T6S

Buy if... ✅ You want sizzling HDR performance: Rated at 1,000 nits and configured with 1,152 dimming zones, the KTC M27T6S packs quite the visual punch.

Don't buy if... ❌ You're very sensitive to black levels and light bleed: While the KTC M27T6S has an excellent dimming algorithm, its lighting still isn't as precise as OLED.

As for refresh, we're talking 200 Hz with an optional, and rather pointless ability to "overclock" to 210 Hz, plus pixel response of 1 ms (by the MPRT metric). The panel type is, as you would expect, IPS.

Of course, the whole point of LCD panels with full-array local dimming is to enable improved HDR performance. The KTC M27T6S duly has VESA DisplayHDR 1000 certification and can do fully 1,000 nits courtesy of 1,152 dimming zones. Youch. Then again, so can plenty of other LCDs with local dimming, and I haven't liked many of those.

Rounding out the details are a stand that adjusts every which way, including pivot into portrait mode, plus DisplayPort and HDMI connectivity. The HDMI ports will only hit 144 Hz, for the record, and there's no USB-C for single-cable connectivity, nor a USB hub. That's probably not a surprise given the competitive price point.

Still, it's pretty nicely put together monitor, albeit largely from plastic, and the design is certainly slick with slim bezels and a mix of black and pale grey plastics from which many more expensive gaming monitors could learn quite a bit. It doesn't look or feel cheap.

Image Quality and HDR Performance

The KTC M27T6S might be affordable, but it doesn't feel cheap. First off, there's no "zone popping" at all. That's a term I just made up and it concerns the really obvious switching on and off of individual backlight zones. You can induce it in many full-array dimming monitors by displaying a star field panning across the screen. And it can look absolutely awful as you track the zones popping on and off as stars pass across the screen.

The KTC M27T6S doesn't do that at all. It also handles a particular 4K HDR video of fireworks on a night sky—which I use as a mini-LED torture test—better than I've seen before on this class of display. It's not perfect. There's still some light bleed and some blooming. But the brighter explosions really light up your retinas. It's very impressive.

In-game is where I was really blown away, however. The brighter desert scenes in CyberPunk 2077 tend to find the weaknesses of OLED monitors; they simply can't handle how much of the panel needs to be driven hard to render the desert sun really well and so tend to look a bit dull. But this dirt cheap KTC monitor absolutely smashes it. The sun is so bright, it almost hurts your eyes. This is a genuine HDR experience and a level of realism that's completely different from your usual entry-level HDR 400 monitor.

The dimming zones are handled deftly, but you can still ultimately see where the zones are firing hard and where they are not. That said, if brighter scenes are where this monitor both literally and figuratively shines, it's after dark in Night City where things don't work quite so well. This is where the limitations of mini-LED technology start to show.
