Asus PG348Q Review
by Lim, May 2, 2017 10:15 pm

Asus PG348Q Review - The competition to HP Omen X 35. How good is the Asus compared to the HP and which disadvantages and advantages we will find within the PG348Q?


Ultrawide QUAD HD (3440x1440), 100 Hz overclocking, G-Sync, and IPS. While the HP Omen X35 is a VA panel, we want to find out which one of them is the better choice for which games or purpose. After I've tested the Omen I really was curious to find out everything within the Asus PG348Q. Compared to the Omen the Asus have a native 60 Hz refresh panel which can be overclocked while the Omen has 100 Hz without overclocking. This, unfortunately, causes an issue called "pixel inversion" in form of horizontal scan lines. I've tried to capture these scan lines on camera which you can find at review updates, but on camera, they are pretty hard to notice. In the video review, I'm trying constantly to compare with the Omen, to give you the best opportunity within your buying decision. At the end, of course, you have to decide with which disadvantages you can live rather. Everything else you will find out in the YouTube video review to the Asus PG348Q and within the review updates within this written review. 

Updates and new information around the Asus PG348Q can be found at the bottom of the article or in the table of contents (if available). Also available within the forum (click here).

Measurement data

The response time of 4 Ms and the overdrive function on the Asus PG348Q works very well. Compared to the Omen, on an IPS panel, you won't have smearing (slow GtB "Grey to Black" response time). 100 Hz vs 144 Hz? Well, you can see a difference. Some people see a very clear difference, some people less. What I really would wish, that the Asus would support ULMB, but as the Omen, it doesn't.

Review Updates

1. Update: Pixel Inversion (horizontal lines on 100 Hz)

Pretty hard noticeable (for me) but still an issue of the pg348q. It's also hard to see on photos and not easy to show how this looks in person, but in general, you have @overclocked modus very fine lines in uniform and brighter / medium image content such as the sky from the Nvidia g-sync pendulum. Thanks for the post@ youtube. I'm also only human and as I mentioned, updates will be posted here in this forum. The link will be in future under each of my reviews to avoid such problems.


2. Update: coil whistle

some users have problems with coil whistle when overclocking in combination with bright images. I tested this with OC to 100 Hz, Brightness 100 and a full white screen. I couldn't notice anything. I also hold my ear directly to the backside of the monitor.


Pros & Cons



- Good and very stable colors
- G-Sync with a range from 30-100 Hz
- Maximum brightness of 367 cd/m2 (300 cd/m2 on data sheet)
- USB hub with 4x USB 3.0 ports
- Very good sharpness - "sweet spot"
- 100 Hz with overdrive for a smooth gaming experience
- Solid build quality (design of course personal taste)
- Very good viewing angles
- Very good grayscale and good color banding abilities
- Very low input lag
- No frame skipping


- Build in speakers



- No gamma settings in the OSD :(
- Viewing angles in darker image content (IPS Glow / BLB).
+ The IPS glow issues on the PG348Q are very noticeable
+ In addition, the IPS glow is "yellowish" compared to AUO panels with a brown/blue Glow
+ Still a lottery, but I couldn't find any person who has a PG348Q with few IPS Glow
- Horizontal scan lines
- coil whistle (It can vary in each individual unit)

Good review :)

But if you had to choose between the both, Which one will you chose ?
Answer from Lim's Cave - December 30, 2017 5:36 am

Personally, the Asus. But maybe even rather the new Alienware AW3418DW, which I hopefully will review soon, because of less IPS Glow issues :)
