Hardware.Info published a review on the To eat or to be eaten: Acer Predator X34P ultrawide G-sync gaming monitor A quote from the article:

The Acer Predator X34P has it all: the extra wide 34 inch monitor has both a high resolution and a high refresh rate, with G-sync as the cherry on top. In doing so, the screen promises to be a worthy successor to the old Predator X34 without 'P' from 2016, which was basically the ultimate gaming monitor at the time. However, competition in the ultra-widescreen monitor segment has become fiercer than ever in recent years. Will the X34P be able to hold its own?

For a long time Acer's Predator X34 was the cream of the crop when it came to gaming monitors. The giant had an extra wide 34 inch IPS panel with an aspect ratio of 43:18 - in layman's terms also known as 21:9. Not only was the resolution high with 3440 x 1440 pixels, but also the refresh rate was not modest at 100 Hz. The presence of a G-sync scaler is the cherry on top.
