Gaming monitors have come a long way since the days of bulky CRT displays. Nowadays, gamers demand the best specs and performance from their monitors, and manufacturers are delivering cutting-edge technology and stunning designs.

And two of the most expected upcoming offerings in the market are the ROG Swift PG27AQDM from ASUS and the Acer Predator X45.

Both are OLED gaming monitors, but both are very different from one another. So, who wins the battle between the ROG Swift PG27AQDM vs Acer Predator X45? Let’s find out.

ROG Swift PG27AQDM vs Acer Predator X45: Specifications

First up, we’ve got the ROG Swift PG27AQDM. This 27-inch OLED beast comes with a 2K resolution, which is great for those who don’t want to splurge on a 4K display but still want to enjoy crisp visuals.

And man, are those visuals crisp! With a refresh rate of 240Hz and a response time of 0.03ms, you’re just about the fastest gamer online. Plus, the anti-glare micro-textured coating ensures you can see everything clearly, even in bright lighting.

And let’s not forget the 1000 nits of peak brightness, allowing you to rock the soon-to-be-released updated Resident Evil 4 with no issues even with the sun beaming through your room.

Additionally, ASUS has gone above and beyond with this monitor’s design. The custom heatsink and optimized internal airflow channels keep it running cooler than other 27-inch OLED gaming monitors, which is great news for those who often find themselves playing for hours on end.

Now, let’s move on to the Acer Predator X45. This 45-inch monster is an ultrawide monitor with a resolution of 3440×1440 pixels and a staggering 800R curve.

Ever seen how captivating the Odyssey G9 is? Well, the 800R of the Predator X45 is even more encapsulating! But let’s talk about the refresh rate, shall we? The X45 supports a whopping 240Hz refresh rate, and with AMD FreeSync Premium, you won’t have to worry about any stuttering or the dreaded screen tearing.

Also, Acer Predator X45 is Eye-safe certified, with the peak of blue light shifted to less energetic wavelengths for optimal viewing comfort. And with a 98.5% DCI-P3 color gamut and per-pixel illumination, every color that eye can see unveils before you in all its glory.

ROG Swift PG27AQDM vs Acer Predator X45: Price

While it’s unofficial, the ROG Swift PG27AQDM is currently available in China for around $1200. By contrast, the X45 is expected to hit the market in Q2 2023 in the EU and US for $1699 – meaning the latter is a far more expensive prospect.

So, the size and the curve add to the price – it’s up to you what are you ready to spend your bucks on.

ROG Swift PG27AQDM vs Acer Predator X45: Which is best?

If a compact monitor that is cheaper but still packs everything the OLED technology has to offer is more for your taste, the PG27AQDM is the way to go.

Specifications-wise, both displays are fairly similar, with the same refresh rate and comparable resolutions. But if you’re someone who wants a larger, ultrawide monitor with more than an aggressive, violent curvet, the X45 is the clear winner.
