I have a samsung ultra hd tv but most stuff looks sharper and clearer in normal HD, even the sky tv guide doesnt look as sharp in 2160 res, Why?
 
Are you playing back UHD BD's? Typically you'll have settings per input and per resolution, and whether it's SD or HDR.

Make sure you adjust picture settings, out of the box Samsungs are pretty bad. Set in vivid, contrast, sharpness to max, all picture processing on, frame interpolation on- all bad.
 
So you have the 2TB Sky Q UHD box?

What looks worse? Because Sky doesn't broadcast a lot of UHD content, you tend to have to download/stream it.

If you are watching an only fools and horses episode on GOLD or something and expecting it to be better because you are watching in 'UHD' then think again.

I don't know if the UI on the SKY Q box is 2160p to be honest.

Have you tried the native apps - Netflix and YouTube etc and found some proper 4k content?
 
I have gone back to the 1080p setting on the sky q box as 90% of stuff looks not rubbish in 2160 but noticeably not as sharp.. And when getting the tv I spent days of fine tuneing the picture settings as the defualt picture settings made the tv look ****... Why are TVs you buy now come with a rubbish picture out of the box, because I can remember the days where you bought a tv and the picture settings were fine and didn't need changing, or Im I just fussy?

There's lightly some truth to that, depends on many variables though such as TV type and cost of TV. I think HDtvtest on YT covered this slightly at some point and rtings.com also. TVs do have a hell of a lot of settings now to be fair as well as decompression being highly relevant, so if you want a preferable picture you're going to need to understand and have a play with what you've got. But that's part of the fun of it imo.
 
I have noticed that a lot of tv's you buy now comes with rubbish powersaving mode enabled, making the picture quality even worse out of the box.
Have you tried the "IMAX Enhanced" stuff on Disney+ or anything on Apple TV?
No, but with it being the tv in the main sitting room I cant be always changing it between HD and UHD, so I just leave it on the HD on sky q, as there's not much UHD being aired atm.. But I just think its kind of bad if you have a 4k tv and have it setup in 4k, but the non 4k content looking noticably worse then in the non 4k setting.. I wonder when 4k becomes the standard in a few years will the quality of 1080p and lower content improve when tvs are set to 4k,, I noticed this a few years ago bewteen 720p and 1080p, that 1080p didn't look as sharp and good as 720p

That's likely because the sources were 720p or 1080i and 1080i was worse.

Thread makes no sense. Clearly 4K UHD is better than 1080p.

This sounds more like an issue with Sky.

I don't understand why you wouldn't just view 4k content in a native app quickly to check what it should look like, if it bothered you enough to post here.

What model TV is it?

You have supplied your own answer to the question.

I thinks its Samsung AU7100 55 Inch

It's an ok TV but anything that's in any way upscaled will look poor on it, loss of detail etc. It's not great for 4K HDR either.
 
Its just annoying that a lot of content on sky q looks better in 1080 than it does in 2160 and that the whole point of the higher resolution, so that stuff looks better not worse.

Output 2160 from Sky box = Sky box handling the upscaling
Output 1080 from Sky box = TV handling the upscaling, or at least doing a decent job of running a 4:1 pixel ratio

That's the Sky box causing you trouble, not the TV.

Even though the compression rate is quite high - at least try some native 4k content through Netflix or Amazon or Disney+ or similar... should be much better. Make sure you run it from the TV's built-in app, not from the Sky box app.
 
It will be better when 2160 becomes the norm and the broadcasters use 2160, then there wont be any need for upscaling. As Im guessing most channels are broadcasting in 1080 now, even when showing lower quality content so no upscaling is needed when on 1080p?

Is it still the case with the Q box that if only a 1080p output is selected on the q box the user can no longer view/watch sky UHD content.
If you set the Q box to 1080 you can't watch any UHD stuff. It will say you need a UHD TV

I have LG CX and the UHD looks miles better than the HD stuff.

Watching non UHD stuff selecting the box at 2160 or 1080 makes no difference to the quality
