If you want to increase visibility in shadowy areas, reach for the black stabilizer slider. Gaming options are many and include FreeSync 2, along with three overdrive levels, a selection of aiming points and blur reduction. It can’t be calibrated but doesn’t need to be. sRGB mode is very accurate and locks out all adjustments except brightness. The 34GK950F is a DCI-P3 monitor, so unless you choose the sRGB mode, your content will be rendered in that gamut. You can adjust the RGB sliders in the Custom slot. Use the latter on a case-by-case basis as it’s not always a pleasing change.Ĭalibration is possible in most modes with four gamma presets and four color temp modes. There are eight picture modes, including an accurate sRGB preset and an HDR Effect setting that attempts to enhance SDR content. Options are evenly split into five sub-menus. At the top, you’ll always see the refresh rate, FreeSync status, blur-reduction, response time setting and HDR info. The OSD is appropriately styled for gaming with a deep red and black color scheme. The result is an inexpensive way to increase a monitor’s color gamut without resorting to exotic RGB LEDs. While quantum dots emit red and green light when excited by a blue LED, extending the gamut volume of those primaries, KDF phosphors work with white light and emit red and green. When the phosphor is excited by the backlight’s LEDs, it emits light of its own, which not only increases color saturation but reduces the backlight’s power requirements. Explained simply, phosphor material is deposited onto a layer of plastic or glass, which goes between the backlight and the thin-film transistor (TFT) or LCD pixel layer. It’s similar to the quantum dot backlights seen on monitors like the Samsung C49HG90.

The 34GD950F’s main draw is its wide gamut, which comes courtesy of a new technology called KSF phosphor. LG 34GK950F (34-inch LED) at Amazon for $804.99 (opens in new tab).
