LG OLED G6 New Firmware Crazy Performance: Up to 3,350 Nits and Full Screen 540 Nits Achieved
Korean manufacturers are making a surprising move with their latest firmware update.
LG has done it again. The LG OLED G6 has significantly increased its brightness with the latest firmware update. Just a few months ago, an update raised the brightness of small screen areas (1% and 5%) to up to 3,500 nits. However, the brightness for 10% area and full screen remained relatively low at 2,500 nits and 400 nits respectively.
This latest update has increased the 10% area brightness to 3,350 nits and the full screen brightness to 540 nits. This surpasses the pure brightness of Samsung's S99H in all measured areas. These figures were measured in FILMMAKER mode, which is aligned with movie standards, not in unnatural settings like Vivid mode.
OLED ABL Limit Overcome: G6 Achieves 3,350 Nits for 10% Area and 540 Nits for Full Screen
These figures are remarkable. Just a few years ago, it was rare for OLED TVs to exceed 1,000 nits. Now we are on the verge of achieving 4,000 nits, which means that the tone mapping process will essentially become unnecessary. This doesn't mean that the entire screen will always be blindingly bright, but rather that the highlight expression of HDR content such as gunshots, explosions, car body reflections, and direct sunlight will become more refined.
The full screen brightness (general TV brightness standard) has reached 540 nits. Previously, OLED panels used an automatic brightness limit (ABL) function to protect the organic light-emitting diodes and reduce power consumption, which limited the full screen brightness to around 150~200 nits. The 540 nits of full screen brightness measured by TecTracks HD completely solves the problem where the screen appeared dark in bright spaces.
The fact that these performance improvements have been made through sequential firmware updates suggests that LG built a significant safety margin into the G6's hardware design. At the initial launch, the latest heat sink and panel potential were not fully verified, but continuous testing seems to have opened up the panel's performance as much as possible.
How to Apply Firmware Update 43.21.62
The procedure is simple. To apply the new firmware to your LG OLED G6, download the zip compressed file through the provided link. Alternatively, you can visit the 'Manuals & Software' section on the official LG support page and search for your TV model name to download the firmware zip file. Unzipping the downloaded file will create a final update file with the extension epk.
Connect a USB memory stick to your computer and create a folder named LG_DTV in the root directory. The folder name must be entered in uppercase letters exactly. Copy the epk file into the created folder and connect the USB memory stick to your TV. When the 'USB Update Ready' message appears on the TV screen, select 'Install' to proceed with the update. After the installation is complete and the TV restarts, the new firmware will be applied, allowing you to experience enhanced HDR brightness.
