ASUS is a leading light in screen production, and these two OLED screens are fine examples of why ASUS is the market leader. Today we will be looking at ASUS ROG Swift PG42UQ vs ASUS ROG Swift PG48UQ; which one is better and which one should you spend your hard earned money on?
The blacks and contrast that OLED screens and OLED TVs can produce are largely unparalleled. This means they are absolutely fantastic for gaming and watching movies and TV.
You might be wondering what the difference is between an OLED screen vs TV, well read on and all will be revealed.
First, let’s take a closer look at these ASUS monitors.

There is not much that separates these two models at all. In fact, the differences essentially boil down to just two things.
The main difference between ASUS PG42UQ and ASUS PG48UQ is the size. The PG42UQ has a screen size of 41.5 inches and the PG48UQ has a screen size of 47.5 inches. Other than this, their performance is going to be the same.
The other difference is that the PG48UQ has one more USB 3.2 port for a total of 5. The PG42UQ only has 4 USB 3.2 ports. Your decision here will be based on your external setup and the other devices you intend to use.
ASUS PG42UQ vs ASUS PG48UQ: Performance
As mentioned, these two screens are essentially the same, and as such their performance is going to be pretty indistinguishable.
One thing you might notice is the difference in these displays’ power consumption. The 42-inch model will use <220W, while the 48-inch screen uses <300W. If your bills have increased recently, like us, this may well be a factor to consider.
OLED display technology really is the gold standard now when it comes to getting the best contrast and the truest colors. Thanks to this and 98% DCI-P3 color spectrum coverage, the PG42UQ and PG48UQ deliver absolutely spectacular picture quality.
If you use an OLED TV as your screen, such as the LG C2, you get the beautiful picture provided by OLED, but your screen is still a TV; it is not designed specifically for PC use. These ASUS monitors are just that, monitors, and as such they have superb response times and fast refresh rates. G-Sync and FreeSync VRR support are also covered so you can make the most of the higher frame rate.
If you’re a console gamer and want to connect your Xbox or PS5 to one of these giant displays, don’t worry. Both of these models come with two HDMI 2.1 ports so you can get the most out of the latest consoles.
ASUS PG42UQ vs ASUS PG48UQ: Price
In the price department, there is again not much difference between the two. This means that your decision will largely depend on which size you prefer.
The ASUS PG42UQ is available from Amazon for $1,399. The ASUS PG48UQ is also available from Amazon, but for a slightly higher price of $1499.
These screens are undoubtedly quite expensive, but there aren’t many great OLED screens available right now, and for the luxury of OLED you have to pay a premium.
ASUS PG42UQ vs ASUS PG48UQ: Which is better?
Your decision between the ASUS PG42UQ and the ASUS PG48UQ is going to come down to your personal preferences. The main difference between these screens is the size. Therefore, depending on available space, you may want to go for the smaller PG42UQ. On the other hand, if space isn’t an issue and you can spare the extra $100, the 48-inch variant offers more visual real estate.
