TL;DR: Good, but with some quirks, worth it if you can get it at a good price.
My KTC M27P6S finally arrived. After using it for 2 days I'm going to write my impressions and thoughts.
Manufacturing date: July 2026
Firmware version: EUR-1.0.1
I will compare it to other high end displays like the PG32UQX MiniLED, an LG CX77 OLED, and my old but trusty PG279Q.
I genuinely think that it is a decent product, but with some quirks that I will explain in each section.
IPS Panel
A regular run-of-the-mill modern fast IPS panel.
Like modern IPS monitors, this has some vignetting on the sides, with the edges of the screen appearing slightly darker. This is visible only at an angle or if you sit close to the screen like me.
My PG279Q from 2015 had zero vignetting, my PG32UQX did have it, and the CX OLED has none. My speculation is that this is due to changes in panel manufacturing in recent years.
Not a dealbreaker, but something you will notice if you are used to an old IPS panel like me and sit close.
Glossy Coating
The most interesting thing of this monitor. This model and a few of other INNOCN monitors that are not widely available are the only ones to offer a glossy coating, so this is something that will attract the attention of many people.
The coating is like the coating on LG OLED TVs, so if you've seen one, this is about the same.
It has some sort of anti-reflection layer because reflections are not fully mirror-like (in a good way). The reflections are mostly noticeable on black areas, but they are subdued in intensity, rather than being fully reflected as they would be in a mirror.
Dust is more visible than on a matte coating, and I already left some fingerprints on the corners while I was handling it. I did not test the hardness of the coating, nor do I want to (lol).
Thanks to this, the image quality is excellent, with zero haze from a matte coating and better perceived black levels when there is ambient light.
Compared to the PG32UQX, this is night and day. The PG32UQX had a terrible, very grainy coating; it introduced a lot of graininess to the image, while this one has none.
The PG279Q had a decent light matte coating, almost no graininess, so these are both equally good in their respective ways.
Overall, I liked it. This is the standout feature of this monitor, so for glossy lovers, this is the only option available right now.
While a glossy coating has better image quality than a matte one, I still would not recommend a glossy monitor for someone who does not like reflection or has a bright room.
STW polarizer
This is the second standout feature of this monitor. I was skeptical about this since reading a review, but I can confirm that it has one.
This feature is also very rare in monitors, only very old IPS panels had it, and then manufacturers stopped implementing it.
Compared to the PG32UQX, this is also night and day. The PG32UQX had a lot of blooming at an angle; this has none, it has the same amount of blooming as when looking at the center, or even less. So, very good.
PG32UQX vs PA32UCG Image is not mine, but this is roughly how my PG32UQX looked at an angle. These polarizers make a big difference in reducing blooming and IPS glow.
On a full black screen with local dimming disabled, there is no IPS glow. Everything looks almost uniform, and there isn't any of the usual yellow glow on the corners. Image from Chimolog Review on a black screen, zero ips glow.
I stress-tested the M27P6S at unrealistic angles, and I could only see a very faint magenta tint at the corners in a fully dark room, so this is excellent.
Local dimming
The local dimming algorithm is dark-biased, something that I personally like. Upon enabling it, especially on SDR, you will notice a decrease in overall brightness.
I tested it in both a bright room during the day and a fully dark room.
During the day, it will be very hard to notice the blooming. In a fully dark room, it is noticeable in complex scenes, but somewhat decent, much better than the blooming that my PG32UQX had.
I hated the local dimming on my PG32UQX, it blasted small elements at full brightness, and the blooming was unbearable (video is not mine, but i swear it was like this).
Thankfully, I can confirm that this does not happen with the KTC M27P6S. It reduces the brightness of small elements so they produce much less blooming (and the STW polarizer also helps a lot!).
I know some people won't like that it is dark-biased, but for me this is good.
You can still customize the degree of blooming you want from the OSD with the "Halo control" option, but I did not fiddle with this that much since it was good for me out of the box. For those who like to prioritize brightness over blooming, it's good that you have the option.
For those who want to keep local dimming enabled at all times on SDR, this is actually somewhat usable. My PG32UQX had a lot of inverse blooming, especially on grey backgrounds. This monitor does not seem to have as much, with just some brightness changes when moving windows and opening context menus.
Local dimming does not increase input lag that much on SDR, but it does on HDR. I'm not able to test the exact amount since I do not have the required equipment, but my PG32UQX also had noticeable input lag when using local dimming.
Due to my GPU's performance, I hover around 60 fps with adaptive sync. This means about 60 Hz or even lower, and I can definitely feel it, but the input lag is similar to that of the PG32UQX. You will definitely feel it in first-person shooters. For competitive play, always disable local dimming on any Mini-LED monitor.
Not a dealbreaker for me. Maybe this can be solved with further firmware upgrades, but it is something to take into account.
Local dimming has an "Auto" setting that is Off for an SDR signal and High for an HDR signal. Sadly, I was not able to save different local dimming settings for SDR and HDR signals.
Anyway, I still usually disable local dimming on SDR (unless I'm playing or watching a dark game/video), since, with the coating and the polarizer, the black levels are actually decent, and local dimming introduces some gamma and color changes on Mini-LED monitors.
HDR
I have to confess that the PG32UQX was better. Since its algorithm always wanted to prioritize brightness, it was much more spectacular.
This is still good, but the PG32UQX was a night-and-day difference between SDR and HDR.
Overall, I still prefer this one since, as I said, I can't stand blooming.
Those who come from edge-lit displays or other non-high-end Mini-LED monitors will still be happy.
You can somewhat customize HDR to your preferences if you do not like the overall presentation, since these OSD settings are still available on an HDR signal: Color temperature, six-axis color saturation, Brightness, and Black Equalizer.
One thing that I noticed is that the algorithm of the monitor does not like to turn the zones fully black if there are elements with medium-to-high APL on the screen.
This was noticeable in a fully dark room when watching an HDR movie. The top and bottom black bars were not fully black at 0.00/0.02 nits unless the screen was almost completely black.
Not noticeable for most people, but I always test in the harshest environment, such as a fully dark room.
Build Quality
The only thing that concerns me about this monitor and that I did not like is the power supply. It is internal. So if it goes bad you are out of luck.
I'm also concerned that if I put my ear right up to the upper vent of the monitor, I can hear some noise. I think it is coil whine from the power supply. I can't hear it when using the monitor at my usual distance (I use the monitor close to my face), but I'm still worried about it since I'm not too sure whether it will increase or whether it is even a fan and I will hear it in a fully silent room.
Quality Control
Bad but I'm still somewhat lucky.
5 dead pixels at the bottom-right corner of the monitor. It would be much worse if those were stuck pixels and closer to the center of the monitor.
Since they are near the corner of the screen and the monitor has a high pixel density, they do not bother me.
(To European Redditors) Buying it from aliexpress
As far as I know, the monitor is only available in the United States and Japan through the official KTC Store.
In Europe, I could only find it from AliExpress. I purchased it from a seller called Ansett Store. The seller always replied to my questions, such as when I asked when it was going to ship or whether the monitor was the European version. It came from Poland.
The monitor I received was indeed a European version. It came with the EUR-1.0.1 firmware, a European Schuko (Type F) plug, and the European energy label on the box, plus the usual accessories like cables, stand, etc.
I do not know if it will be available from other sources. This is speculation, but it seems like this seller is either KTC in disguise or someone in charge of selling to the European market.
I managed to get it for €345 (~$388) thanks to AliExpress coupons, so make sure to take advantage of those.
Conclusion
I like it overall, specially at this price point, seems like my old PG279Q can finally retire (11 years old!), The only concern I have right now is the power supply.
I consider this worth it, especially if you are after the specific, somewhat niche feature set that this monitor has, such as the glossy coating combined with a MiniLED backlight.
A few months ago, I was eyeing an equivalent 4K 27-inch OLED, and the prices were almost double that of this one. Combined with the fact that my usage is 60% static and 40% gaming, this was a no-brainer at this price point. Fingers crossed it lasts me as long as my PG279Q!
So personally:
Pros:
- Glossy coating
- STW polarizer
- Shadow-biased algorithm
Cons:
- Internal power supply
- High chance of dead pixels
- Higher input lag when using HDR with Local Dimming
