as a resolution I personally prefer 1440 to remove the need for scaling.Wouldn't use a TV for anything demanding accuracy or colour correct work personally. Wouldn't want to be sat that close to a large display either.
Give me a pair of Dell ips 27" 1440 all day long.
But the truth is these users don't have high end 1440 ips monitors and with current pricing and market trends they are unlikely to any time soon. What they have is 1080 tn panels and little interest in high end colour calibration. To a degree in digital design, for the wide array of end users I design for (both their screens and perception) these are likely to differ widely from mine anyway!
text readability is highly desirable at small sizes, but to my eye it far exceeds their current setup once hdr is switched off.
