4k v 1080p HD TV

InsideInsurance

If you cannot tell the difference between true 1080 and 576 then either you have a 3" screen or you really need to get so specsavers.

I will perfectly accept the argument that you dont NEED to be able to see every stray hair and wrinkle on the heroines face to make it a good movie but to say there is no difference is plainly wrong.

Of cause the problem here can be that (a) freeview is heavily compressed and so some of the extra detail is lost in the compression and (b) SD is upscaled to 1080p and whilst discussed at length already on this thread about the creation of detail out of nothing etc if you are talking a reasonably large screen I would argue that upscaling generally does improve the apparent picture quality to most. With these two factors the delta is probably smaller.

Dont know whats going on with your colours though, dont have any notable colour saturation difference between HD and SD. There is a modest picture quality improvement on Sky but doesnt equal that of BluRay. Mainly I switch to HD for the DD sound output and even on non-DD programs the sound comes out more "open" on the HD channels -v- the SD ones going via my amp

Personally I can tell the difference between SD and HD, a lot of people say they can't tell but it's blatantly obvious for may (maybe I just have good yes?)

Hop onto iPlayer and turn the HD on/off, you can normally tell straight away (assuming you have a reasonable quality monitor)

It all depends on the size of TV and how far you sit from it. I sit about 12ft from my 37in TV and can't see difference if I move closer I can.

here is a handy chart

Seems a lot of people need to visit the opticians. If you can't see the difference between SD and HD then something is either wrong with your TV or with your eyes.....

Have a look at the above chart

Never understand why people knock the "early adopters".

Without these people we would still be watching 40" CRT TVs and recording everything on magnetic tape.

....and your point is? You can spout all the science you want, however, if someone can't tell the difference in a home environment then something is either wrong with the TV or their eyes.
As far as 4K goes, as the prices drop to mid range HD set territory then given the choice I would go for the 4K if I was in the market for a new TV. I'm personally holding out for an OLED 4K so hopefully, summer next year will see the prices of the LG's become accessible, even sooner if someone else manages to crack the production process...;):D

Strider and anyone else who doesn't see the point in 4K TV - get yourselves down to Currys or similar and look at them. They ARE better than HD and you CAN see the difference at respectible viewing distances. If you don't, hopefully there's a Specsavers nearby, and hopefully you have someone to take you there!

A lot of shops used to sell over-priced HDMI cables like that. Two screens, side-by-side, one with all the controls set to make the picture look awful, the other tweaked to perfection (and coincidentally using an £80 HDMI cable).

I'm not saying that 4K screens aren't better, but shops play a lot of tricks when trying to flog the latest fad.

Yes, indeed they do.
I can't actually go into Currys/etc, because i've been known to tear strips off of salesman who try to feed me a load of BS. Especially if that BS is PC/laptop/audio or photography related.

The over priced gold HDMI cables (and SCART before them) was one of the things that used to wind me up.

Anyone who understands digital, will understand that by definition digital is simply binary code, 1's and 0's in fast succession, a 1 is either TTL 5v or CMOS 3.3v.
Basically it's either there or it's not, so unlike with old analogue signals fancy cables make NO difference at all, either it'll work or it won't. Just like when Sky TV went digital, now when the signal drops below a set standard your picture simply freezes, instead of being able to make out a picture through a wall of "snow" as you used to do on analogue.

Paying £90 for a HDMI cable doesn't make someone look like an expert, it makes them look like a f**king idiot. I don't know if it's the same now as it was some years ago, I suspect they're not that expensive anymore, but I also have it on good authority that PC world actually pay around £3 for those expensive HDMI cables (the gold Belkin one's).
