LG has presented its latest display innovations during the K-Display event in Seoul, featuring its 4th-gen OLED panels. Among these, we find the world’s first 27in 540Hz OLED panel, with support for an even faster mode at lower resolution. The brand also showcased new 83in TVs boasting up to 4,000nits of brightness, for a blasting a rip-roaring HDR experience.
Based on LG’s Primary RGB Tandem OLED technology, this new high-refresh monitor aims to give demanding users the speed they need without having to settle for a TN LCD panel. It delivers up to 540Hz refresh rate in QHD (2560×1440), with the possibility to reach 720Hz by lowering the resolution to HD (1280×720). Unlike existing dual-mode displays, which switch between 4K/QHD and FHD, this time LG went further down to enable this outstanding speed. However, while more speed is welcome, opting for a four-times lower resolution to unlock 33% more frame rate may be too much to ask from many users.
The brand also indicated that thanks to the new OLED panel, this unnamed monitor can reach up to 1,500nits peak brightness, while covering 99.5% of the DCI-P3 colour gamut. By separating the yellow-emitting layer of the 3rd-gen OLED into distinct red and green layers, the Primary RGB Tandem technology enables higher brightness and contrast than ever before. LG claims that 4th-gen OLEDs boost colour brightness by 40% and peak brightness by 33%. Furthermore, the improvements brought to the diodes and panel power supply are said to reduce consumption by 20%.
These specs look quite similar to the 720Hz OLED monitor recently announced by Chinese brand SDC, which is also based on LG’s 4th-gen OLED panels. Thus, we can expect LG’s solution to also offer HDR True Black 500 and ClearMR15000 certifications, not to forget OLED’s renowned 0.03ms pixel response times.
But that’s not all, LG also unveiled a new 83in OLED panel powered by the Primary RGB Tandem structure, enabling it to hit up to 4,000nits. This one will be perfect for those watching movies, delivering an impactful HDR representation and bringing OLED’s brightness up to Mini-LED and other LCD-based solutions, while maintaining excellent black levels.
Either way, these 4th-gen OLEDs tick all the boxes for an excellent experience, probably at a price to match their greatness. If you want to get a taste without waiting for the faster 540Hz model, the Asus ROG Swift PG27UCDM at £1,098 is a nice option, trading speed for a higher 4K resolution.
