Another 720 Hz OLED monitor announced – LG and ViewSonic enter the game!

Calendar 12/12/2025

LG and ViewSonic unveil new 720Hz OLED gaming monitors based on the RGB Tandem panel. 540Hz at 1440p, a 720Hz dual-mode at 720p, up to 1500 nits HDR brightness and a 0.02 ms response time – we take a closer look at the specs, key differences and their true potential for e-sports.

The market for ultra-fast gaming OLED monitors is just gaining momentum. LG and ViewSonic have officially unveiled their first 540 / 720 Hz models based on the new RGB Tandem OLED panel (4th generation OLED from LG Display), which is set to be a direct competitor to QD-OLED.

So far, the fastest version of this panel has made its way into Asus and Acer monitors. The absence of LG Electronics among the launch partners was quite surprising, but the company is catching up by presenting the model LG 27GX790B. ViewSonic responds with the XG273F-2K-OLED design.

One panel, two modes: 540 Hz or 720 Hz

All four monitors – from Acer, Asus, LG, and ViewSonic – are based on the same 27-inch flat OLED panel with a resolution of 2560 × 1440. The specifications look impressive:

  • full coverage of DCI-P3

  • true HDR

  • brightness up to 1500 nits (window 1.5%)

  • 335 nits full screen, noticeably more than in the previous generation of OLED

  • response time of 0.02 ms G2G

The panel operates natively at a refresh rate of 540 Hz at 1440p, but with the dual-mode option, users can switch to 720 Hz at 720p. Importantly, at 720 Hz, OLEDs are likely to offer better motion readability than the upcoming 1000 Hz LCD monitors, precisely due to the extremely low pixel response time.

Differences in Execution and Connections

Despite the identical panel, manufacturers differentiate their models with details:

Asus

  • coating glossy

  • DisplayPort 2.1a (80 Gb/s)

LG 27GX790B

  • coating matte

  • HDMI 2.1

  • DisplayPort 2.1 (without confirmed bandwidth)

ViewSonic XG273F-2K-OLED

  • HDMI 2.1

  • DisplayPort 1.4

This shows that not only the panel but also the selection of ports can be crucial for the most demanding gamers.

Prices and Availability

LG and ViewSonic models will be available for sale soon, but their prices have not yet been revealed. We expect more details during CES 2026. For reference – Asus PG27AQWP is already available for sale.

What does this mean for the market?

RGB Tandem OLED is entering the market with a very strong impact. 540 Hz at 1440p and 720 Hz at 720p, higher brightness, and full HDR make it clear that we are talking about a new stage in e-sports monitors. If prices from LG and ViewSonic prove to be competitive, the LCD market may face a serious problem. It seems that 720 Hz OLED will become the new benchmark for the most demanding gamers.
