After much anticipation, WePC finally gets its hands on the new ASUS ROG Swift PG42UQ gaming monitor – billed as the world’s first 42-inch OLED gaming monitor on the market. The new big-screen gaming display will come equipped with a 138Hz refresh rate (overclockable), 4K UHD screen resolution, near-instantaneous response time (0.1ms quoted), and HDMI 2.1 support – making it the perfect choice for both PC and next-gen console gamers.

Its large 41.5″ 4K OLED panel looks set to provide immersion in abundance, showcasing perfect blacks, an infinite contrast ratio, and 98% coverage of the DCI-P3 spectrum. It will also feature ASUS’ new internal heatsink that allows the OLED panel to perform in a more efficient manner – reducing its chances of image retention and permanent burn-in.

Despite being classed as a gaming monitor, the PG42UQ looks set to tick all the various boxes from both a gaming and productivity standpoint too. ASUS claim a pre-calibrated color preset of <2 right out of the box, alongside a plethora of additional gaming features in an attempt to seperate it from the market’s OLED gaming TVs.

Furthermore, ASUS has also installed a new brightness uniformity feature which provides better levels of consistency when it comes to brightness levels. This is ROG-exclusive feature that really helps the PG42UQ stand out from the competition.

All being said, we’ll be putting the PG42UQ through its paces in the following article to see how it stacks up against some of the market’s leading gaming monitors and TVs. We’ll be testing the display for gaming performance, color accuracy, build quality, and general functionality, concluding with our thoughts on its value for money.

So, will the ASUS PG42UQ manage to compete with the top LG OLED TVs or will it fall short of the mark? Let’s find out.
