4K or 1080?

text is blurry on tvs even of the same sizes as monitors. its not just a scale factor issue but also that some tvs have a different pixel arrangement than monitors do which are better oriented for crisp display of shapes but not the horizontal and vertical lines of text.

the 30hz issue was for pre hdmi2.0.

now, would a 4k tv fix that? yes and no at the same time. at higher resolutions text will normally be smaller (and rather unreadable) however you can counter this by using higher than normal windows font sizes and internet zoom levels. not as big of an issue. the real kicker however is that icon sizes in programs and applications will be small and hard to see and some in-program text doesnt have an option for changing sizes which means it will be hard to read.

for this reason i would suggest 1080p in a television if you are going to use it as a pc monitor. i personally use a 40" 1080p tv myself and it works out fine. if you sit 5-7ft back from a larger 50-55 you should have a similar experience.

dont get me wrong... 4k displays are really nice but i'm not so sure it would work well for a pc monitor for anything other than desktop, web and gaming unless you bought one in a rather large size like 60"+ and sat rather close to it.
