The KTC H27P3 is a unique 27″ 5K 60Hz monitor with a 1440p 120Hz Dual Mode!

It offers an IPS panel with a high 2,000:1 contrast ratio, an exceptional color gamut, a high 500-nit peak brightness, USB-C with 65W Power Delivery and more – all that at a very attractive price of around $570! Let’s see how it handles our tests.

Image Quality

The monitor is based on BOE’s ME270L7B-N23 ‘True Black’ IPS panel, which boasts a static contrast ratio of 2,000:1, doubling the typical IPS contrast for noticeably deeper blacks.

Other panel-related specifications include a very wide 99% DCI-P3 and 99% Adobe RGB color gamut coverage, 178° wide viewing angles, dithered 10-bit color depth support for smooth gradients and a strong 500-nit peak brightness.

The 5K resolution of 5120×2880 pixels or 217 PPI (pixels per inch) is definitely its main selling point, especially considering that other 5K displays without the Dual Mode feature go for notably higher prices (~$850 – $1200).

To test the display’s capabilities and accuracy, we’re using our Calibrite Display Pro HL colorimeter paired with DisplayCAL.

Note that we’re testing the EUR-1.0.1 firmware version.

In the OSD (On-Screen Display) menu, under the ‘Display’ settings, you’ll find several ‘Preset’ options: User (Default), Movie, Photo, ECO, Reader, RTS and FPS.

Options other than ‘User’ just have different brightness, contrast, hue, saturation and Black Equalize values pre-set that cannot be adjusted by the user. So, for full customization, we recommend using the most accurate default ‘User’ mode.

If you scroll a bit further in the ‘Display’ section, you’ll find the ‘Professional Modes’ options, including Native, sRGB, DCI-P3, Adobe RGB and BT. 2020.

These modes (except Native) only lock contrast, gamma, hue/saturation and Low Blue Light settings and they clamp the monitor’s native color gamut down to the respective color space.

Color Gamut

The KTC H27P3 has an exceptional color gamut with 165% sRGB gamut volume and 99.4% coverage, 97% DCI-P3 coverage and 97.6% Adobe RGB coverage, making it fit for professional color-critical work involving both web and printing.

By default, colors will be oversaturated in Windows, so you can use the sRGB mode to clamp the gamut down to 101.8% sRGB volume and 98.7% coverage.

Image Accuracy

Due to its wide color gamut in the Native mode, colors will be oversaturated with high Delta E of 3.04 average (color deviation from the target, less than 1.5 is considered good) and 8.11 maximum (target is less than 3).

Gamma tracking, on the other hand, is excellent at 2.22 (target is 2.0), while color temperature is 6625K in the User mode (target is 6500K), which is close to ideal as there’s no noticeable tinting to the whitepoint.

The sRGB mode improves the average Delta E to 0.77, but the maximum is still a bit high at 4.04 for the blue color, while red is 3.0. It’s not ideal, but it’s good enough for basic color-critical work.

Average gamma is excellent at 2.2 and it follows the sRGB tone curve, but the color temperature is a bit high at 7004K in the most accurate User mode, resulting in a very minor bluish tint to the whitepoint. Luckily, you can adjust color temperature, as well as brightness, in the monitor’s sRGB mode.

We also tried using a software clamp, such as the one available in AMD GPU drivers, the novideo_srgb tool for NVIDIA or Windows 11 Color Management, but it resulted in a high Delta E of 1.92 average and 5.97 maximum.

For professional use, we recommend using a colorimeter and calibrating the display. Alternatively, you can try using our ICC profile to create a 3D LUT. With it, we got a more accurate Delta E of 0.44 average and 3.22 maximum.

We also tested the DCI-P3 and Adobe RGB modes.

The DCI-P3 mode clamps the gamut volume down from 116.9% to 103.3% with 97.2% coverage, Delta E of 0.73 average and 4.21 maximum, 6990K color temperature in User mode, and 2.21 average gamma.

The Adobe RGB mode reduces the gamut volume from 113.7% to 98.5% with 96.9% coverage, with a Delta E of 0.9 average and 4.11 maximum, 7004K color temperature (User mode) and 2.21 average gamma.

Calibration

For full calibration, we set the brightness to 19/100 for 120-nits and used the ‘Native’ mode with ‘Custom’ color temperature and red, green, and blue color channels set to 50, 49, 50, respectively, to get 6543K.

We got a Delta E of 0.3 average and 1.19 maximum, as well as improved sRGB tone curve gamma tracking with 2.22 average.

You can download our ICC profile here.

Brightness & Contrast

We measured a high brightness of 498-nits and a minimum of 34-nits, which makes the monitor suitable for use in both particularly bright and dim rooms.

At 200-nits, we measured a static contrast ratio of 2249:1, which results in noticeably deeper blacks than that of typical IPS panels with around a 1,000:1 contrast ratio.

Of course, blacks aren’t as deep as that of VA panels, which usually have a contrast ratio over 3,000:1, nor as deep as that of OLED panels and monitors with full-array local dimming, but none of those technologies are available with 5K resolution.

HDR

While the KTC H27P3 can accept the HDR10 signal, it doesn’t have proper display hardware (OLED panel or full-array local dimming) for a true HDR viewing experience.

HDR content can still benefit from the display’s wide color gamut for proper DCI-P3 mapping and dithered 10-bit color depth for smoother gradients, but since there’s no dimming control, details in shadows and highlights will be lost.

Now, HDR can still look subjectively ‘better’ than SDR to you on this monitor, but it won’t be an accurate representation of the creator’s intent and you won’t get deep blacks or bright highlights.

Again, this is an expected level of HDR support for a 5K display in this price range, especially after considering that there are no 5K monitors available with OLED or FALD technology. You can find proper HDR displays in this price range, but they won’t have 5K resolution or some of the features of the H27P3.

In HDR mode, the display clamps the gamut when viewing SDR content with 95.5% sRGB color space coverage and 105.9% volume. It has a maximum brightness of 431-nits, 6388K in the Warm color temperature preset, an average Delta E of 1.55 and a maximum of 5.79, and 2.18 average gamma.

Pixel Density & Dual Mode

The KTC H27P3 has a high pixel density of 217.57 PPI, which results in incredible detail clarity with sharp text and plenty of screen real estate available. It’s also a pixel density sweet spot for macOS due to Apple’s HiDPI / Retina rendering system.

In order to make small items such as text big enough to be easily readable, you’ll need to apply some scaling (200% recommended), which will decrease the amount of screen space but improve detail clarity and readability.

Gaming at 5K is quite demanding, but it’s feasible with mid-range GPUs thanks to upscaling technologies such as DLSS and FSR. Better yet, the KTC H27P3 has a 2560×1440 120Hz Dual Mode for smoother gameplay.

Now, because the monitor is displaying its non-native resolution at 2560×1440, the image won’t be quite as crisp as that of a native 27″ 1440p display.

Still, we found the image to be surprisingly sharp and usable due to the decent pixel density of 108 PPI, though the monitor is not using integer scaling, which would have displayed every 2×2 block of pixels as one pixel at 1440p (without interpolation) for an even sharper native-like image.

Below are microscope photos of a 1-pixel red crosshair on a black background. The left photo was taken at 5K, while the photo on the right was taken at 1440p. You can see how the pixels are simply doubled horizontally, but the vertical row is interpolated, causing minor blur.

Here’s a close-up of how this interpolation (and lower resolution) affects text.

Finally, here’s the image of the monitor’s RGB subpixel layout.

Performance

At 120Hz, you get drastically smoother motion clarity in comparison to the standard 60-75Hz displays. In fact, we find that the difference between 60Hz and 120Hz is much larger than the difference between 120Hz and 240Hz.

The higher refresh rate also makes screen tearing a lot less noticeable, and you get lower input latency.

For latency and response time testing, we’re using OSRTT.

The KTC H27P3 has five response time overdrive modes: Off, Standard, Advanced, Ultra Fast and Auto.

Here’s how the monitor performs at 5K 60Hz.

The ‘Auto’ mode is supposed to behave as variable overdrive, but at 60Hz, it just has the same performance as ‘Off.’

The ‘Off’ mode is too slow and shows the panel’s native performance with 23.51ms average GtG (gray to gray) response time. ‘Standard’ kicks it up to 17.26ms with a low 0.5% overshoot error, and ‘Advanced’ improves it even further to 12.74ms, but with a bit higher 4.9% average overshoot error.

We didn’t notice any pixel overshoot (inverse ghosting) in real use with the ‘Advanced’ mode, so we recommend sticking with it at 60Hz. ‘Ultra Fast’ is too aggressive with 24.8% overshoot error.

Although most transitions are in red in the heatmaps above, 83.33% of all pixel transitions are made within the 16.67ms refresh rate window using the Advanced mode, so it’s a decent result for 60Hz.

Regardless of the response time speed, 60Hz will feel choppy in comparison to 120Hz, which is why you should use Dual Mode whenever you play games.

Here are the response time results at 120Hz.

At 120Hz, ‘Auto’ has the same performance as ‘Standard’, both of which are too slow. Instead, you’ll have to use Ultra Fast, which won’t have as much inverse ghosting as it does at 60Hz.

You get an average pixel response time speed of 10.39ms, which is a bit slower than the 8.33ms refresh rate window. There’s a 7.67% average overshoot error, but it’s not noticeable during everyday use.

Overall, the pixel response time speed at 120Hz is subpar, but this is expected from IPS Black panels. Most importantly, there’s no dark level smearing associated with most VA panels and for most users, the amount of ghosting will be tolerable or even negligible.

Of course, if you mainly play fast-paced competitive FPS games, the monitor’s response time speed is far from ideal, but if you’re after a display for eSports titles, you should be looking at higher refresh rate monitors in this price range anyway.

For casual gaming, the pixel response time of the KTC H27P3 is good enough.

Here’s how the monitor performs in Blur Busters’ UFO ghosting tests. We’re using the 960 Pixels Per Sec test with the camera’s shutter speed set to 1/4 of the refresh rate with fixed focus, ISO and color temperature.

Below, you can see how it compares to several other displays we tested.

Moving on, the KTC H27P3 supports variable refresh rate (VRR) with a 48-60Hz range at 5K or 48-120Hz at 1440p for tear-free gameplay.

Another advantage of IPS panels is smooth VRR performance without brightness flickering that’s associated with VA and OLED panels.

The KTC H27P3 also supports MBR (Motion Blur Reduction) via its MPRT feature in the OSD menu. This technology uses backlight strobing to reduce perceived motion blur at the cost of image brightness (limited to 178-nits). However, there’s too much strobe crosstalk (image duplication), so we don’t recommend using it.

You also can’t use MBR at the same time as VRR and it introduces screen flickering that’s invisible to the human eye, but can cause headaches after prolonged use to sensitive users.

The backlight of the monitor is otherwise flicker-free, and there’s a low-blue light filter option available as well.

Next, here’s a look at display latency.

We measured a display latency of 8.67ms at 5K 60Hz and 5.12ms at 1440p 120Hz. Both results mean that there’s no perceptible delay between your actions and the result on the screen. The display latency is a bit higher at 1440p 60Hz, as we measured 12.94ms, though it’s still below the 16.67ms refresh rate cycle.

Next, we didn’t find any excessive IPS glow or backlight bleeding, dead or stuck pixels, inversion artifacts or frame skipping issues.

However, there was a small 2mm long speck of dust beneath the screen layer, but it’s in the bottom-right corner and not noticeable during everyday use.

Lastly, here’s the image uniformity test result.

The brightness and contrast uniformity are decent. The bottom-right part of the screen is a bit darker than the rest (up to around 25%), but we didn’t find this to be noticeable during everyday use.

Features

On the rear of the monitor, there’s a directional joystick for quick and easy navigation through the menu. Moving the joystick up, down, left or right also serves as a quick menu for certain functions that can be changed in the menu. To turn the monitor on/off, press and hold the joystick for a few seconds.

Possible hot key shortcuts include brightness, volume, mute, Game Assist, Preset, Color Temperature, Black Equalize, HDR and Aspect Ratio. Sadly, Overdrive and Dual Mode options cannot be assigned as shortcuts.

Besides typical image adjustment tools (brightness, contrast, color temperature), there are some advanced settings available too, including sharpness, aspect ratio (full, 16:9, 4:3, cannot be changed with VRR enabled), gamma (from 1.8 to 2.4), hue/saturation and automatic input detection.

KTC also offers a desktop application called MMC (Monitor Management Center), which you can use to make all OSD-related adjustments, assign keyboard hotkeys for certain functions or picture modes to different applications.

You can download the MMC app here, though you’ll need to change your browser’s preferred language to ‘Chinese (Simplified)’; otherwise, it will just take you to the English homepage. Alternatively, use this direct download link (clicking it will start the download immediately).

You can also use third-party apps, such as ControlMyMonitor, to make the following OSD settings:

Useful gaming features include Black Equalize and Night-Vision (improve visibility in dark scenes by altering the gamma curvature), crosshair overlays (including Auto Crosshair that changes color depending on the background), Eagle Eye (puts a highlighted rectangle in the center of the image), a refresh rate tracker and an on-screen timer.

Other OSD settings include language, OSD setup (position, timeout, transparency, style), power LED indicator (on, off), audio, USB Upgrade (for firmware updates) and factory reset.

Although there is a ‘KVM’ option in the OSD menu, the KTC H27P3 doesn’t have built-in KVM functionality since it only has one USB-C port and two USB-A 3.0 ports.

In order to get 5K resolution over USB-C, the ‘KVM’ option needs to be set to ‘Type-C USB 2.0’.

Design & Connectivity

The monitor’s design features a minimalist aluminium stand. It’s tilt-only, but the screen is VESA mount compatible via the 75x75mm pattern. Most of the design features a textured matte finish, while the upper part of the rear is glossy.

The rear KTC logo also emits a subtle white glow.

Next, the screen has a light matte anti-glare coating that diffuses reflections without making the image appear too grainy.

The bezels are ultra-thin (1mm) at the top and at the sides, while the bottom bezel is a bit thicker at 17mm. There’s also a 5mm black border (2mm at the bottom) around the screen before the image starts.

Connectivity options include HDMI 2.0 (limited to 4K 60Hz or 1440p 120Hz 8-bit), DisplayPort 1.4, USB-C (DisplayPort Alternate Mode, up to 65W Power Delivery), a headphone jack, and two USB-A 3.0 ports with firmware update support.

To use the USB-A ports on the monitor, you’ll need to connect the display’s USB-C port to your PC.

In the box, along with the monitor, you also get the external power supply, a power cord, a DisplayPort cable, a USB-C cable, a screwdriver for assembling the stand, a user guide/warranty card and a factory calibration report.

Price & Similar Monitors

The KTC H27P3 goes for $750, but it can often be found on sale for $570. Even at $750, it’s the most affordable 5K display available, and the only model with 1440p 120Hz Dual Mode (at least in the US).

15% off code on Amazon: 15KH27P3（~2026.1.1）

On KTC’s official store, it’s available for $520 with the 12% off code: sitewide.

The Philips Brilliance 27E3U7903 is another popular 5K model with an IPS Black panel. It doesn’t have 1440p 120Hz Dual Mode, but it has a glossy screen surface. It’s not available in the US, though.

Other models based on the same (or similar) panel, include the ASUS PA27JCV, the BenQ PD2730S and the ViewSonic VP2788-5K, none of which have Dual Mode and go for $800 – $1,200.

Finally, there are older 5K models, such as the Apple Studio Display and the Samsung ViewFinity S9, but these use typical IPS panels with a 1,000:1 contrast ratio and go for up to $1,600.

Conclusion

Overall, the KTC H27P3 is an excellent monitor for the money. It’s the most affordable 5K display yet it offers very useful features, such as Dual Mode and VRR, which aren’t available in some other, more expensive models.

The sRGB mode factory calibration could’ve been a bit better, but this is easily fixable with a colorimeter, which any serious photo/video editor should have. You can also use our ICC profile to improve this.

Further, the pixel response time speed isn’t ideal for 120Hz, but this is the limitation of IPS Black (or BOE’s True Black in this case) technology, and it is fast enough for casual gaming. More importantly, there’s no dark-level smearing or VRR brightness flickering.

We would’ve liked to see proper integer scaling implemented as well as an additional USB-B port for KVM functionality, but this would’ve also increased the price.

The 5K resolution delivers excellent detail and ideal pixel density for macOS, the 500-nit peak brightness helps cut through glare in well-lit rooms, the 2000:1 contrast ratio offers noticeably deeper blacks than typical IPS panels, and the wide color gamut makes it a solid choice for work across various color spaces.

On top of that, you get plenty of gaming features, such as the 1440p 120Hz Dual Mode and VRR support for smooth and responsive gameplay, which is why we highly recommend this monitor to anyone looking for a great hybrid monitor for both work and gaming.
