Correct me if I'm wrong but they rather say more resolution = better fractional scaling.
In the hope that scaling artifacts will be hidden more efficiently if there's enough room for better resizing calulation.
That however seems to depend heavily on the said resizing method and is something true in the context of using a PC/GPU covering the full output resolution.
Cooperative software is sine-qua-non.
Personally I prefer integer scaling since it's easy and very light, it's right, fecking flawless, and either black bars or 'overscan' are problems only for those who can't deal with those, too OCD maybe (I don't laugh since I used to be like that)
Still, for more refined effects and indeed more occurrences when integer scaling offers useable correct ratios, a higher resolution is beneficial too, of course.
Yet even on a Full-HD panel integer is still awesome to have, plenty of source resolutions can be integer-scaled leaving either only slim black bars or little overscan.
And when there aren't good factors available, well, integer scaling is optional ya know. :p
Back on the topic of TVs (and external sources), I don't know if they do or don't, the thing is most manufacturers on first look use very basic/shitty interpolation, which seems to break things in most cases.
You can see the Sony sets do pretty good scaling,
apparently integer, though it might really be 'close-to-integer with gentle~good interpolation' instead.
I'm okay with that, it's just too bad most review websites don't test TV's upscaling quality using revealing patterns but random pictures.
