1080p scaling a 1440p Panel really that bad?

[phatboy]

If this has been asked before, apologies

So been looking at picking up the AOC 31.5" Freesync screen over the last few days but did some research and found the quality that a 1440 panel reproduces 1080 resolution in can be less than acceptable because of the way it creates the HD image

Not too worried from the PC's point of view but I have a PS4 and Wii-U also connected to the same screen that myself and the kids use and don't want to ruin the experience on those.

Been told that 4K recreates 1080p perfectly and would do a good job of 1440 as well???? so confuzzled!

Is it all really that bad?

Any help would be great as don't want to get overspend on a 4K panel I do not really have the power to drive unless I upgrade my GPU and then scale down on everything unless I really have to

Thanks

1080p will look pretty good , 1440p will look like ass.

I take it that's on a 4k panel?

Thanks for the extra information and experience,

I am getting close to just putting up with the times I do actually use the PS4 it's slightly degraded, the Biggest improvement I want is the PC
