Quick Review of LG 27GX790A: Shining in Brightness, Vibrant Colors, and Speedy Performance in 480 Hz OLED Display
=================================================================
The LG 27GX790A, a desktop OLED display, stands out for its impressive HDR performance. Tom's Hardware, a reputable source for tech reviews, employs a rigorous testing methodology to evaluate monitors' HDR capabilities. This process involves measuring grayscale and luminance tracking, examining color charts for oversaturation and gamut coverage, and checking peak brightness and HDR mode effectiveness [1].
One of the key features of the 27GX790A is its ability to automatically sense and switch to HDR10, eliminating the need for calibration in HDR mode [2]. The display offers a nice pop with extra verve, retaining fine detail in all parts of the image [3]. Luminance tracking on the 27GX790A is accurate, with the option to change it if desired [4].
The 27GX790A's hue accuracy is excellent, and colour temp presets and RGB sliders remain available in HDR mode [5]. Adjustments can be made to the colour temperature to achieve a cooler look, if preferred [6]. The peak brightness can be adjusted, and variable brightness can be toggled on for HDR gaming [7].
The Electro-Optical Transfer Function (EOTF) of the 27GX790A tracks close to the reference, with a slight dip as it approaches the tone-map transition at 60% brightness [8]. The display delivers accurate HDR color tracking with a slight oversaturation [9]. If greater BT.2020 coverage is desired, a Quantum Dot screen would be needed to beat the 27GX790A [10].
LG claims the 27GX790A has a maximum brightness of 1,300 nits for a 1.5% window, and the display can deliver more brightness than nearly all its competition [11]. The contrast of the 27GX790A is infinite due to its OLED technology [12]. Saturation tops out at 85% red, 75% green, and 95% blue [13].
The HDR grayscale tracking in the Gamer 1 mode of the 27GX790A is slightly warm [14]. However, this does not detract from the overall impressive HDR presentation offered by the 27GX790A, which is one of the best desktop OLED displays for HDR content.
