Today, LG has again proved why it is at the forefront of OLED display technology. The South Korean tech giant has unveiled “the world’s fastest OLED monitor panel,” a 27-inch (QHD) 540Hz gaming monitor which can be boosted all the way up to 720Hz with help from Dynamic Frequency & Resolution (DFR) technology.

The announcement comes as LG shows off its latest OLED panels at K-Display, taking place in Seoul between the 7th and 9th of August. In a press release, the company details the new fastest panel, also noting that its highest resolution OLED is viewable at the event – a 21:9 ultrawide with a 5120 x 2160 pixels. Possibly the LG UltraGear OLED GX9, which launched a few months back.

In addition, it is unveiling the world’s fastest OLED monitor panel for the first time. LG Display’s 540Hz 27-inch OLED panel (QHD) applies Dynamic Frequency & Resolution (DFR) technology to achieve an ultra-high refresh rate of up to 720Hz (HD) depending on the user’s needs. Combined with fourth-generation OLED technology, it boasts the highest level of picture quality among OLED monitor panels, with 99.5% DCI-P3 color reproduction and a maximum brightness of 1,500 nits.

Due to DFR technology, the higher frame rate comes at the cost of resolution. While the OLED panel will be able to achieve 540Hz at its native 1440p resolution, if you want to boost the refresh rate higher, the resolution will have to be compromised. To manage the full 720Hz refresh rate, that means dropping the resolution down to just 720p, which is half of native.
