Will a 4k TV make my blu-rays look crap?

I'm in the market for a new TV and am debating on whether to upgrade to 4k. I'm just a bit worried that the large blu-ray collection I've spent the last few years gathering will now look terrible when upscaled.

Is this a genuine issue, or do 4k televisions handle it quite well?

SD looks crap upscaled on a 4k TV.

Pretty much all HD sources look fine.

What size screen you looking to get?

Blu-ray looks great on my 49inch. Even DVDs still look nice IMO.

I have a 55 and it looks fine.

My mate has a 65 and Blurays still look fine on that. Anything SD is really ropey though.

I've just got a 65" OLED and Bluray still looks good on it. Heck, even my Frasier DVDs look good on it!

Similar, in the 40-something range. Thanks.

Just sit a bit further back ? Sounds flippant, but a serious solution if your room layout allows.

Also remember that a lot of 4K content, films especially, are derived from a 2K source so only slightly higher resolution than 1080p.

Sorry to upgrade an old thread but here is my twopenny contribution. Having upgraded to 4K all around recently, I have seen 3 'regular' blu-ray films - Airport (1969), Jurassic Park (1993) and Rouge One (2016) by playing them on a 4K BD layer and watching them on a 4K TV. In all 3 cases, there was significant improvement in PQ, especially resolution, from what I recall from our older flatscreen 'HD-ready' TVs.

With DVDs however, this upscaling was less noticeable and variable. Also, I felt that playing DVDs on DVD players (rather then the 4K BD players) that I have retained and linked to the systems but watching them on the 4K TV offered better results. But thus far, I have not encountered any deterioration of PQ compared with older TVs.

HD-Ready TVs were only 720p as far as I know, so you would see a bump just by virtue of the fact you'd be seeing the whole 1080p picture.

Even 720p looks fine on a 4K TV.

DVD can look quite poor and the low bitrate SD channels look dreadful.

The biggest issue with DVDs will be the compression rather than the resolution. It's a shame that DVDs are still stuck using quarter of a century old compression codec.

My own feeling is that DVDs look 'poor' because the resolution is not as good as BDs or 4KBDs and there seems to be only a little upscaling. We are now very used to Full HD and better PQ and so any SD looks poor by comparison.

But they certainly don't look worse than they did on older TV's. Last night I watched a couple of episodes of old X-files DVDs on my 65" OLED and the PQ, while clearly inferior to modern media outputs, was not 'crap' by any means.

I upgraded my Netflix to 4K (where broadcast) and this REALLY looks great on both the OLED 4K in the lounge and non-OLED 4K TV in master bedroom.

I noticed that some of the channels on Freeview SD are actually now using AVC rather than MPEG2 so should in theory look better (although they have blatantly just done that so that they can lower the bitrate even further to squeeze more rubbish channels in!).

The problem is the amount of upscaling required.

To make a 1080p picture fit a 4K screen is has to be "blown-up" to a factor of 4 and it looks good.

For a DVD on a 1080p screen it's the same and it looks fine.

For a DVD on a 4K screen it's 16x. There's only so much you can do with detail that isn't there, unless you have the technology they have on CSI of course.

Last night I took out my old DVD of The Hot Rock and watched it on my 49" Sony 4K TV. Watched through the 4K BD player, the PQ was a bit meh but then I swapped to my old (2006) Sony DVR with component video and coaxial audio. The PQ was quite good DVD standard (not BD or 4KBD quality but certainly no worse than before). No problem at all.

If you’re watching DVDs (well actually anything really), remember not to overdo the Sharpness setting. It can make things look artificial and bring out the worst in transfers like bad compression artefacts.

I’m guessing your Sony DVR is giving a softer image which may be easier on the eyes. Maybe try turning sharpness to 0 on both your TV and BD player
