How much did you lower your settings? To medium or low? Because that is what I would have to in order for 4K to look worse than Ultra 1440p in my experience.Hmm, I've very recently tried this and have to disagree.
IMO 1440p Ultra looks better than 4K lowered settings.
EDIT: Actually I am going to partially take that back. I think it depends on the game. Some do look better in 4K at lowered settings.
These days most games there is very little difference in IQ between Ultra and High, but a huge impact in fps. Coupled with not needing as much AA the grunt needed for 1440P Ultra to 4K High is not that huge. But there is a very visible difference in IQ. Going forward the gap in IQ from 1440p and 4K will only widen as more games target 4K also.
