I recently got a lovely new 4k/UHD TV. It's only a cheap Digihome 48" set from Tesco but at least it lets me join the 4k revolution

I haven't used it long yet but I'm already finding the default settings it came with typically dreadful being far too bright and seeming to lack the punchy impactful colour my last set had.

I saw a few recommended settings online for it and have tried entering them but they too seem too bright for my tastes as I tend to prefer a more understated, natural look to the picture but with a decent amount of colour.

Are there any good test images for getting the basic settings right on a 4K TV? I have a PC connected and the TV has Youtube built in so any good image/video links would be great along with tips of what to look out for when setting the various controls?

I am posting a separate thread in the Online Entertainment forum about 4k content, as that seems more relevant place, but am also looking for some good content that really shows off 4Ks advantage over 1080P. Ideally looking for cheap or free content as I don’t have the money to splurge on a UHD Bluray player after buying the TV, but do have Amazon Prime and may be persuaded to resub to Netflix if they have a good enough 4k library?

Any advice much appreciated.

A PC won't do you any good unless it supports 4K, which is highly unlikely.

Amazon Prime is your best bet. Netflix 4 K isn't cheap.

Well the PC should be fully 4K compatible since it has a GTX970 in it, which has the all important HDMI 2.0 connection. The TV recognises it at 4K at 60HZ so should be ok for 4K I would have thought.

I think I have now got the settings about right, found a set online that give a nice dynamic picture with tonnes of colour. Been watching 4K footage on youtube for the past couple of hours, some wildlife shots and various cities around the world, seriously impressive stuff. If only the film studios, tv companies etc would get behind this format full force and shoot some more stuff in it, would be great.

Only thing I notice on some videos with a lot of fast action (e.g. time lapse videos on roads, lakes, sky etc when there is a lot of fast movement the picture starts to get noticeable artefacts/blocking in places but suspect that is just as much to do with youtubes high compression of the video as anything with the set?

You have one of the few graphics cards that supports 4K. As you say, anything you stream or download is at the mercy of poor compression.

You can download from here rather than stream. Some nice quality 4K images without such hard compression.

Without wanting to hijack the op specific question I was wondering when 4k broadcasts will become more mainstream.

They are unlikely to, as there's little point in them - people don't want to view from as close as 4K requires - and if they used the same higher bandwidth (as needed for 4K) for existing HD broadcasts it would be superb anyway.

Demo material is largely a waste of time as it doesn't represent anything meaningful and is usually boring to watch anyway. Amazon now stock a limited range of 4K Blu-ray movies you may enjoy.

Its taken around 10 years to get where we are now with HD and technology is moving so much faster. We already have every premiership match in UHD and f1 will be next year also the new season of the blacklist and no doubt new ones due out next year. I reckon within 8 years we'll be where we are now only watching UHD.

It's £8.99 a month. Considering all you get for that and it being only £1.50 dearer than Netflix HD/2 Screens, I'd say it's very good value.

Amazon Prime Video is £5.99 per month, and only £6.58 per month (£79 per year) for the free delivery service and Amazon Music).

By comparison, Sky Q is £44 per month. Everything is relative I suppose.
