Controls and OSD

The KTC OLED G27P6 uses a single 4-way joystick to navigate the OSD. The main part of the OSD is opened by clicking the button, but you can also pull it in either direction to access four quick menus. By default, they're brightness, input selection, KVM switch and gaming setup (timer, crosshair, FPS counter). You can change the left, right and bottom quick menu to something else, like contrast, volume, factory picture profiles, HDR toggle, and similar. Only the upper quick menu is locked to input selection.

The main part of the OSD is split into the following sections: Display, Color, Gaming Setup, Input, System Set, and Advanced Settings.


The Display menu is where you can adjust the brightness, contrast, black level, aspect ratio, and sharpness, and select one of two picture presets: Standard or User. As soon as you change any setting in the OSD from its default value, you're automatically switched to the User preset.


The Color menu contains the usual color temperature, gamma, hue and saturation settings. Here you'll also find the blue light filter, HDMI color range selection (if you're using that input), and the color gamut settings: sRGB, DCI-P3, Display P3, and Normal. The latter is the default setting, and the only one that doesn't lock you out of adjusting other values in the Color menu, as well as contrast from the Display menu.


The Gaming Setup menu contains all of the gaming-related settings of the KTC OLED G27P6, such as adaptive synchronization toggle, virtual crosshairs, FPS counter, timer, colors and effects of the rear-facing glowing logo, and even a Low input lag toggle, which isn't documented in the user manual or anywhere else, but we'll see what it does in the gaming performance section of the review.


The Input menu lets you toggle automatic input switching on and off (keep it off if you're using the KVM switch), select the active input, as well as control the KVM switch, which you can use manually or just let it automatically adhere to the currently active video input, which is what I found to be the most intuitive option in practice.


The System Set menu offers OSD-related options (position, transparency, timeout), quick menu reconfiguration, volume control and even sound profiles (the default one is called "Nomarl" – oh, the irony!). The most important option here is LED Indicator, because you can use it to turn off the annoying front-facing power LED.


The final menu, called Advanced Settings, is where KTC decided to put all three burn-in prevention techniques offered by the KTC OLED G27P6. They're OLED Pixel Refresher, OLED Expert and Screensaver. I didn't find a word about them in the user manual or anywhere else on KTC's website, so you're on your own in figuring out what they do. The OLED Pixel Refresher can be set to Auto, Enable, or Start at shutdown. It's just a standard LG Display's pixel "cleaning" algorithm which comes on all monitors built around their WOLED panels. The OLED Expert is a shorter, 1-minute panel maintenance program, which can be started manually whenever you spot any signs of burn-in, or something more benign, like brightness and color uniformity inconsistencies. Screensaver is exactly that – an integrated black screen screensaver, that turns on when you're not active on your PC for a set amount of time (5, 10, 20, or 30 minutes). You can also deactivate it and simply let your computer's power settings turn the monitor off.

Two OLED-specific options are obviously missing from the OSD: pixel-orbiting and Auto Brightness Limiter (ABL) toggles. The pixel-orbiting feature moves the picture by several pixels in random directions, at random intervals. I didn't find it overly eager or too distracting, nor did I run into any issues with useful screen elements getting hidden from sight, so I don't see the lack of a pixel-orbiting toggle as a big issue. The ABL toggle is a different story. If you can't get used to the fact that the brightness of the panel constantly (and visibly) changes depending on what's shown on the screen, then this will be a dealbreaker for you. Most other OLED monitors let us turn this feature off to get a constant level of brightness at the expense of maximum brightness, which gets locked to around 200 cd/m². For most users – myself included – that's an acceptable compromise. KTC likely has the possibility of adding this feature in a future version of the firmware, assuming they decide to do so, but as it currently stands you can either accept the admittedly unobtrusive ABL or look elsewhere. I'm told by the company that ABL can be turned off by switching the monitor to the so-called Reading Mode, but this is a feature apparently reserved for US versions of the monitor. As I reviewed the EU model, I can't comment on the characteristics of the Reading Mode or what ABL behaves like when Reading Mode is activated. I find it bizarre that such feature would be region-specific, but it is what it is.
