Why bother with such high resolution?

3840x2160 resized to 1920x1080 generally does look better than native 1080p after compression

In reply to a post by MrSaffron:

Graphics card and PC speed will be a factor with rendering and handling any downsizing needed.

Remember frame rate issues back in 2001 when the first 2 Mbps streams from Apple Quicktime trailers were around.

Sure - also on my pc Firefox seems to handle the downsizing of 2160p better than Chrome although Chrome is smoother for 720p and 1080p at full screen (1920x1080)

it says to select original but I have no original as an option, its max 720p.

but on the subject of resolution, personally I find it hard to see the difference between watching netflix at 720p on my pc browser (as netflix in IE silverlight can only do max 720p) and super hd on my ps3.

There is a big difference in quality on netflix from 360p to 480p which I suspect is due to encoding more than resolution, and a moderate difference again to 720p but above that I barely notice.

on youtube I usually watch in 720p, and only bother to use 1080p if I need to read fine text in the video or something.

To me 4k is a clear fad. Sort of like HD on phones.

ok your link and batboy's link I can play in 4k in IE (firefox the option isnt there in menu).

Both no stuttering but I do get a momentary glitch after going full screen.

Basically default youtube behaviour unless unticked hardware acceleration box is this.

Software video rendering, hardware video decoding in window
Hardware video rendering and decoding full screen.

So try full screen if window is stuttering and it may well be smoother.

Mine is ok in both tho, maxes at about 20% gpu usage and not much cpu usage.

I have a haswell 4670k overclocked to 4.3ghz and gtx 760.

On the quality, looks no different to 1080p videos to me.

Have you tried the 1440p version of http://www.youtube.com/watch?v=WHvuHj5ssEc - that's certainly the best option for my hardware and bandwidth - really clear image and no frame drop

in IE I did the highest one there which said 4k next to it.

With XP running Firefox v30.0 I get these options: 2160p 4k, 1440p hd, 1080p hd, 720p hd, 480p, 360p, 240p, 144p and auto - if I select auto in full screen then it plays at 1080p. 2160p will play in full screen (with some frame drop) but I get a more comfortable buffering margin with 1440p (and no frame drop) and the image is a little crisper than 1080p even though 1440p is re-scaled to fit my monitor at 1920x1080.

We queried it and that was what we are assured they are doing, which makes it pretty cheap when TalkTalk charge £13.50 for 40/2 product

Once I see a speed test with high upload I'll be less sceptical

I changed to the 40/20 product yesterday and would happily show you a speed test but can't see an option to add an attachment.
The BT speed test shows an upload profile of 20Mb.

For the BT speed test copy and paste the contents of the two text boxes of results, where you read the upstream IP Profile. (FYI the upstream IP Profile is always the value of the upstream maximum of the product. The downstream IP Profile is 0.9679 of the connection speed).

For the thinkbroadband speed test and the speedtest.net ones, they provide a link you can publish/post for people to click.

here is one from - I assume - a different customer http://community.plus.net/forum/index.php/topic,1286...
