AMD launch was yesterday! Today’s topic is HDR (High Dynamic Range). Monitors with corresponding hardware in the form of Full Array Local Dimming (FALD) in combination with an IPS or VA panel have been around for a long time, but they are still quite expensive and only a stopgap solution in my opinion. The KTC (Key to Combat) G42P5, in turn, is – in that respect – anything but a stopgap. This monitor houses a current LG OLED C2 panel. This means we are dealing with a W-RGB subpixel layout. Furthermore, this already tells us that it’s a newer WBE OLED-Evo panel (about 20% more peak brightness) and where the journey will go in terms of color space coverage. DCI-P3 here we come!
But let’s take it one step at a time. Unknown to me so far, KTC is a Chinese manufacturer that currently wants to gain a foothold on the European market. In principle, I don’t think that’s a bad thing at all, because as long as the goods are good and the support also works in the event of an RMA, then that helps us here in Europe immensely to swirl the otherwise much too high prices a little. KTC had my test sample delivered to me from Hungary. Whether there is a distributor there or only import into the EU zone – I have not researched.
The G42P5 was delivered in typical gaming packaging. The panel is well protected in it and should arrive at the customer without damage. The price for the panel only is currently around 1,199 Euros. If you need a stand, you have to order it as well. Here are another 100 euros on top. Sounds funny, but that’s how it is. Don’t kill the Messenger… I don’t do these insane prices. At the end of the day, the price is on par with the Alienware QD OLED. Of course… According to KTC, the RRP is 1,399 Euros with stand. Interesting!
The OLED panel has been made more or less non-reflective by KTC with a matte coating. Thus, reflections are also significantly lower than on my LG OLED C1. I personally don’t like this matte finish, I would prefer a glossy display. But, that’s just my opinion. We’ll take a quick look at the rest of the technical specs – advertised by KTC.

You can believe the 99% Adobe RGB, but you don’t have to. LG’s OLED panels are geared towards HDR content, which is known to take place in the DCI-P3 color tree. And, the LG OLED panels do not use quantum dots to extend color gamut coverage. Let’s measure everything, but for now we’ll leave it as a marketing joke. The HDMI 2.1 ports do not come with the full 48 Gbit connection as usual. The HDMI 2.1 ports are limited to 24 Gbit/s. For the consoleros among you, you can use the 2160p @ 120 Hz, but only with 10 Bit @ 4.2.0 Chroma. On a PC with a GPU that supports HDMI 2.1 with DSC, 10 bit @ 4.4.4 Chroma will also work. No need to understand why KTC limits the bandwidth here so much.
KTC apparently doesn’t let itself down either and has had the monitor calibrated. According to the protocol, the sRGB mode should have an avg dE 2000 of 0.62 and the DCI-P3 mode a dE = 0.88 in terms of color accuracy. This, too, needs to be examined. It is already clear that the Adobe RGB with a dE of 3.34 cannot have a color space coverage of 99%.
So, let’s take a closer look at the hardware. I don’t expect many surprises today, since I’ve been using an OLED TV myself for a long time, but you never know…
