Not on this chart, mainly because "ultrawide" is such a variable term, but generally most ultrawide resolutions fall somewhere between 1440P and 4K in terms of performance required.Umm, I seem to remember that there used to be ultra wide comments on the chart. I'm I misremembering, or...?
For example various manufacturers describe all of the below as ultrawide:
2560x1080 (2.76 MP)
3840x1080 (4.1 MP)
3440x1440 (4.95 MP)
3840x1600 (6.1 MP)
5120x1440 (7.37 MP)
5120x2160 (11.06 MP)
In comparison to:
1080P 1920x1080 (2.07 MP)
1440P 2560x1440 (3.69 MP)
4K 3840x2160 (8.29 MP)
