Fast and vibrant review of LG 27GX790A OLED monitor, boasting a swift 480 Hz refresh rate.
The LG UltraGear 27GX790A OLED monitor has made a name for itself in the gaming world, standing out for its exceptional brightness and contrast performance compared to other OLED gaming monitors. This 27-inch QHD OLED panel boasts a peak brightness of around 1300 nits and covers an impressive 98.5% DCI-P3 color gamut, delivering vivid colors and deep blacks that are characteristic of OLED technology.
Unlike many earlier OLED panels, such as the MSI MAG 272QP X50 which reaches about 302 nits full-screen white brightness, the 27GX790A's brightness is significantly higher, making it more suitable for use in brighter environments.
Regarding contrast, the 27GX790A benefits from OLED's inherent infinite contrast ratio, due to perfect black levels when pixels are off, similar to other OLED monitors. This results in contrast that is essentially unmeasurable in terms of typical numeric values but is perceived as exceptional across OLED models.
Calibration on the 27GX790A generally involves reducing brightness to a target luminance level (e.g., 200 nits) for better color accuracy without impacting its infinite contrast capability. After calibration, the brightness may be dialed down significantly for more accurate SDR levels, but contrast remains unaffected because OLED black levels stay perfect regardless.
The 27GX790A also offers a 480Hz refresh rate and very low response time (0.03ms GtG), making it exceptionally suited for competitive gaming with no compromise on visual quality. Its performance with regard to brightness and response time places it ahead of many comparable OLEDs, including the MSI MAG 272QP X50 and the Alienware AW3425DW.
In summary, the LG UltraGear 27GX790A offers superior brightness performance and maintains OLED’s infinite contrast advantage, with calibration primarily optimizing brightness for accurate color reproduction without sacrificing black level quality. This makes it one of the top-tier OLED gaming monitors in brightness and contrast compared to peers.
| Aspect | LG UltraGear 27GX790A | Comparable OLED Monitors (e.g., MSI MAG 272QP X50, Alienware AW3425DW) | |----------------------|---------------------------------------|-----------------------------------------------------------------------------| | Peak Brightness | ~1300 nits (peak HDR) | ~300 nits (SDR typical) | | SDR Brightness | ~37.5% higher than older LG OLEDs | 240–302 nits | | Contrast | Infinite (perfect blacks via OLED) | Infinite (standard for OLED) | | Calibration Impact | Brightness reduced for accuracy; contrast unimpaired | Similar effect; calibration reduces brightness to ~200 nits without contrast loss | | Refresh Rate/Response | 480Hz / 0.03ms GtG | Up to 500Hz (QD-OLED), similar response times; depends on model |
In the realm of smart-home devices and technology, one could argue that the LG UltraGear 27GX790A OLED monitor shares similar characteristics with advanced gadgets. The monitor's exceptional brightness performance and preservation of infinite contrast, traits typically associated with OLED technology, are elements that set it apart much like how innovative tech products distinguish themselves.
When it comes to calibration, the LG UltraGear 27GX790A behaves similar to smart-home devices that require adjustments for optimal performance, with the process primarily focusing on brightness for accurate color reproduction without compromising on black level quality, just as one might adjust settings on their smart gadgets for best results.
