That super low price means a few things have been left out. There are no USB ports, speakers, or LED lights. But there are some gaming aids like aiming points, a timer, and an FPS counter. Local dimming has four levels, and HDR includes four modes of its own. You also get a somewhat unique look with areas of light gray in the back and on the stand, which makes a refreshing alternative to the usual black. It’s hard to overstate the value of a $290 monitor that offers this much.
Aside from a few simple white graphics, the M27T6S’s carton does nothing to attract attention. Only a small label on the side tells you what’s inside. The screen and upright, along with the base, are packed in crumbly foam and assembled without tools. A 100mm VESA mount is provided for aftermarket arms, but you’ll have to source your own fasteners. The cable bundle includes IEC for the internal power supply plus DisplayPort.

Black accents are textured and look a bit like carbon fiber. A purple KTC logo graces the back of the panel, and though it seems to glow, it is not backlit. The front bezel is flush and narrow with a tiny logo front and center. Reach around the back right to find the OSD joystick, which is the only control.
The upright includes a small cable clip and delivers full ergonomics. There is a 5.2-inch height adjustment, plus 5/20 degrees of tilt, 45 degrees of swivel, and a 90-degree portrait mode. Movements are firm, but there is a little wobble at the fulcrum. The M27T6S is stable, but you’ll need to tweak it a bit to get the screen exactly where you want it. The stand is tall enough to set the panel vertically while centering your eyepoint.
The input panel faces downward and includes two HDMI 2.0 ports, which top out at 144 Hz in QHD resolution. They are compatible with consoles and support HDR and VRR. A single DisplayPort 1.4 supports the full overclocked 210 Hz, along with Adaptive-Sync and HDR. There is a USB port, but it is only for service; it doesn’t accept peripherals or provide power. Audio is only available through the 3.5mm headphone jack; there are no internal speakers.

After brightness and contrast, there’s a black equalizer control that brightens up shadow areas for better visibility. I found no need for this when local dimming was engaged. Preset is where you’ll find the nine picture modes. Changing any parameter puts the M27T6S into User mode, where all controls are active. At the bottom, Professional Modes contain the five color gamut selections. Native shows the monitor’s full color, which covers over 117% of DCI-P3.
Advanced Settings is where you’ll find the four HDR modes, which work when an HDR10 signal is present. HDR Cinema is the default and best choice there. If 1,300-nit highlights are too bright for your environment, the HDR600 mode dials back the peak. Or you can just lower the brightness slider, which remains active in HDR mode. Here also are the local dimming options with three fixed levels and an auto mode. They bump contrast up to over 41,000:1 and are especially effective for HDR content.
My M27T6S was a little cool in tone out of the box, with a lighter image than I expected. Gamma is set to 2.2 by default, but it measured closer to 2.0. A few tweaks of the RGB sliders and a change to the gamma 2.4 preset set things right. The Native color gamut setting is very colorful, especially in red and blue. It will appeal to most users, but if you want to dial it back just a bit, the Professional Modes include P3 and sRGB options. My recommended settings are below.
The value quotient was uppermost in my mind as I put the M27T6S through its paces. The gaming experience was on par with the best monitors I’ve reviewed, thanks to low input lag and an excellent overdrive. Though variable OD is an option, I found it worked best when set to Advanced. That tracks because my GeForce RTX 4090-equipped system pegged the frame rate at 210fps. QHD will let you do that with a wide variety of video cards. There was no need for additional processing to keep the action smooth and free of artifacts. Blur was minimal, not quite gone but well below the level of distraction.
Control response reminded me of the fastest monitors I’ve tested. You’ll see on the next page that it measures up to many faster, more expensive screens. Mouse and keyboard inputs were instantly translated into 180-degree turns and precise circle strafing. I could aim easily and consistently as well. The M27T6S is fully competition worthy.
The HDR picture was breathtaking in both color and contrast. The Mini LED backlight has 1,152 dimming zones, so it is very effective at boosting dynamic range. I measured almost 45,000:1 in HDR mode, and it presented an almost OLED-quality image. Blacks were true and finely detailed while highlights popped from the screen. I could see a case for the HDR600 mode or simply turning the brightness down because some flashes were a bit too dazzling when playing in my dimly lit office. The M27T6S is one of the few HDR monitors that lets you dial down the output. I noted that there were no internal speakers, so game audio had to be relegated to headphones, which I plugged into the 3.5mm jack. There are also no USB ports so those needing a hub won’t find it here.
For everyday use, the M27T6S works well with its 109ppi and a sharp image. Color is the star with vivid primaries that make it look even brighter. I normally set the peak to 200 nits for testing, but I found I had to reduce it a bit to 180 to keep fatigue from setting in. This is a seriously bright display that stands out from its competitors. My only complaint is that the stand is a bit wobbly. It keeps the display rooted, but adjustments take a little more trial and error to get right. I was happy to see a large height range so I could set the panel at vertical with my eyes at center screen.
Takeaway: The M27T6S is a great all-around display and an excellent gaming monitor. Though there are higher refresh rates out there, it made the most of its 210 Hz with a precise overdrive and completely usable MPRT backlight strobing. With low input lag, it delivered a competition-level play experience. The picture is incredibly bright and colorful for any purpose, from work to entertainment. With such a low price of admission, it’s hard to fault.
