    While none of us need this yet sounds like things on the audio video front as still changing pretty rapidly.


    Anyone want to guess if/when TiVo releases a DVR (or provides the software for a third party DVR) that supports it? My guess is 3 years.

    For over 60 years we watched TV at 525 with 4X3 CRT, the biggest CRT I know of was 40". Now the TV designers can keep upgrading from the new 1K standard, to 4K, 8K, 10K, etc. but IMHO you can't walk into a room with a 4K TV and tell within a few seconds if the picture is coming in at 1K or 4K, you can tell if it an old 525 transmission. Most people with HDTV can't get the full range on their HDTV because of the compression that both the cable and most OTA do to the signal, only a BD player with a well made BD movie disk do you get the full 1K on your HDTV, even that is not mind blowing, but I do try to watch most of the movies I can on BD (over 30Mbs to my 80" HDTV TV).

    I've been reading about HDMi 2.1 coming for over year now.
    It will still be awhile until it shows up in all the TVs. I'm fine with my HDMI 2.0a or b HDMI inputs for now.

    Although the biggest thing I would want to use from HDMI 2.1 is eARC. Since it would allow all the Advanced audio codecs to be used over the ARC. Of course the source device, TV, and receiver would all need to have HDMi 2.1.

    You can easily tell right away whether you have a 1K/720P source or a 4K/2160P source on a UHD set. The difference is very obvious between a 1K source and a 4k source.

    Even more advanced HDR sounded interesting, but ya the whole idea is you will need to replace everything again. Will be interesting to see if stuff starts to come with HDMI 2.1 at this years CES.

    Side by side your correct, but just walking into a room with a 4K HDTV I can't tell 1080i from a 4K transmission on say Netflix, I have not seen the new 4K BD player loaded with a BD 4K movie, so that may be a difference I could see quickly. The 4K TV I see is at a friends home and it is a 60" OELD, picture is great, but I still can't tell by just looking if it is 1080I cable (say CBS) or 4K Netflix. (4K Netflix is his only option to get 4K now). I never checked the degrade of a 720P xmission, but I don't see much of a difference on my 80" HDTV. (CBS vs ABC)

    Not necessarily. If your device's SoC is of recent vintage and has the capacity, I believe the manufacturer could conceivably provide a FW upgrade to enable at least some of the HDMI 2.1 features such as eARC and/or HDR10+ (although the latter should not require the new HDMI version).

    Here is a chart from the article that shows what each version of HDMI added:

    Netflix is low bitrate rate UHD. But even without being side by side, if it's a good quality UHD stream, it's still easy to tell. And a UHD BD with a 4K DCI, there is no comparison. SInce there is just so much more detail on the screen.

    But just like with HD, with UHD there are good looking titles that show the benefits of the UHD resolution. And bad titles, that look like they are in a lower resolution.

    I've always thought the biggest benefit is with HDR. Because you can see the difference that makes no matter how far you are from the screen,

    What source today will give you HDR on a HDR ready 4K TV ? (Besides a 4K BD player with a good 4K movie.)

    In addition to my Sony UHD BD player for HDR content. I use a Roku Stick+, 4K FireTV (2017), Popcorn Hour Rockbox, Xbox One X, and PS4 Pro. As well as some of the internal apps from the TV play back HDR content.

    Streaming sources such as Amazon, Netflix, and VUDU offer titles in HDR. I am currently watching them via the apps on my 4K TV and they do show up with the HDR encoding.

    Game consoles support HDR too. PS4 requires Dolby Vision (it's how they get it on all the consoles), Xbox One X uses HDR10.

    The PS4 is HDR10. It's just only 1080P but still uses HDR10. When I had a PS4 I got HDR from it. And my setup is only HDR10 and HLG capable. I have a PS4 Pro now. Which of course still has the same type of HDR. HDR10.
