HP Omen X 35 Review

HP Omen X 35 Review - 100Hz curved Ultra-Wide Gaming Monitor. In general an awesome image quality but still with a bigger problem and some downsides


Dude, I really was happy when the HP Omen X35 arrived. The design is something really innovative and new within gaming monitors and displays in general and I really like it combined with the 35" Inch. Oh, and yes, you can see a difference between 34" and 35" Inch. There is only few information about the Omen, so I was also really curious how good the Omen X35 will pass my test. I've got my Omen directly at the German HP store, with some student discount :P. But even with a discount, the Omen costs me 1090€, which is still really a crazy price for a monitor. So, HP attacks the Asus PG348Q and Acer X34A with the Omen. With a VA panel, you will have very good blacks but since only a VA panel does not promise you to have stable blacks within viewing angles in dark image content, you should take a closer look at this topic. The good, no clouding and backlight bleed, the bad, viewing angles are very poor at the Omen, even compared to other VA panels. The Omen uses an AU-Optronics panel. So, a 100 Hz native refresh rate, G-Sync, ultra wide, ultra-design, 3440 x 1440... The review is a bit long, but I still hope that it helps you within your buying decision :).

Measurement data

Within the response time of 4 Ms and the overdrive function from the Omen, in general, I was positively surprised. However, the disadvantage is that while using overdrive you will become problems with lags/stutters. This means, that every 4 - 5 seconds the image has extreme motion blur for some several milliseconds. It's curious that these intervals, where this issue occurs, sometimes need around 15 seconds before it occurs. Well, the positive thing, within games this issue isn't really that noticeable and while playing I couldn't notice it at all. So let's hope that HP will be able to release a fix with some firmware updates.

Some more "issues" with the Omen X 35


VA Smearing

If you buy a VA panel, you probably will know that you will have more smearing compared to an IPS or a TN panel in darker image content. It's just something which all VA panels have and what we can not evaluate as a negative point for the monitor.

Review Updates

1. Refresh Rate

The HP Omen X35 uses a native 100 Hz refresh rate panel (and not a native 60 Hz panel with overclocking abilities) Model number: AUO (AU Optronics) with the serial number M350QVR01.1.


2. Frame Skipping

As the question came @ youtube if the omen uses a native 100 Hz panel. One user told us, that HP has made a mistake on their page. The support in Germany really couldn't help me. At this test, we have frame skipping of "only" 1 frame each every 1.11 seconds. The video is taken with 60 fps and a shutter speed of 1/100, so you won't see each frame but you easily can see the "afterglow". Frame skipping results in stuttering. I couldn't notice any stuttering with the Omen X35 in games, only some in CS GO.


Here you also can watch a short video where I made the frame skipping the test.
Here is a short explanation of frame skipping.

Pros & Cons



- Intense and vibrant colors (consider viewing angles and more washed out colors on the left and right / above the 16:9 aspect ratio)
- G-Sync with a range from 30-100 Hz
- Max. brightness of 350 cd/m2 (300 cd/m2 stated)
- USB Hub with 3 x USB 3.0 ports
- Very good sharpness - "sweetspot"
- 100 Hz
- Very clean design and a solid processing
- Very nice blacks
- No clouding and backlight bleed
- Very good protected monitor in the box



- No contrast settings
- Actually buggy overdrive settings with lag (not really a problem in games)
- "slowest" panel technology with smearing in darker colors/objects
- Frame skipping (1 frame)



- No gamma settings in the OSD
- Viewing angles, especially in darker image content (silver shine effect)
+ Issues with viewing angles on the HP Omen X35 are very obvious(!)
