xh90 / x900h - native youtube app isn't 4k? Viewport is 1080p

Hi all

Has anyone else noticed (via "stats for nerds") that your "viewport" isn't 4k (obviously when viewing 4k content), it's 1920 x 1080.

It should be 1920 x 1080 *2 if it was 4k. I believe.

Cheers J

What does it say the current res is though? What about the bandwidth?

If you could attach a picture, it would be great.

Has @Win_88 wrote, you are displaying (see current resolution) at the maximum 4k@30fps , so what's the problem that will affect everyone? that the label says wrongly that you have a fullhd screen?

Do please correct me if I'm wrong, but a 1080p "Viewport" - means you're watching everything, 360p, 2160p content, at 1080p...

This TV, it's native youtube app has no way of setting a 4k resolution / "viewport" and defaults to 1080p.

Yes you are wrong , BTW you are right it should display the view port as 4k (1920x1080x2 God know why they don't write 4k explicitely ;), but if you look at the stats it also say that your are viewing the video at 3840x2160@30fps out of the native 3804x2160@30fps so at the maximum resolution available...

Ok. so you're 100% certain, that the viewport is shown incorrectly on this TV, and the actual resolution is 2160p while watching 4k? Have you verified this with Sony / your own equipment?

To me, logically, I'm watching 4k content, "downscaled" to 1080p (much like we could watch 4k stuff, if we're mad enough to, on a 720p laptop display.)

There is only one thing certain in anyone life and I have no way to check it with Sony, but if you watch downscaled 4k content on a 4k display you would watch it in a smaller window. If you look at a 4K video on an HDready display this is what you get (that is far from what you get on your tv). Nonetheless if you are looking for an official answer from Sony you should open a ticket to their support service.

Ok cheers, I'm not sure the window would be smaller.. The TV can fill the screen running lower resolutions just fine! I might get round to it at some point.

The tv normally upscale to 4k any content (since it is 4k) even in lower resolution, but following your reasoning you are assuming that: the tv identify itself as a FHD display, the youtube app in any case stream the content at 4k than downscale it to FHD and later on the TV identify that youtube display a lower resolution than the tv is capable of and upscale it again to 4k....a little complex, isn't it? as you can see in the picture I sent Youtube app identify the display as HDready, stream HDready@30fps and display HDready even if the video is available in 4k@60fps...

That also makes sense mate, but we don't know if it's rendering a 1080p viewport, with 2160p inside it, stretched up to 4k lol..

Yes it could be... but if this is the case, at least getting real close to the tv or with the right pattern you should notice a downscaled/upscaled content, and if you don't ... does it really matters? enjoy your tv and take care

I'm sorry to hear it, is it only one? Unfortunately it could be better if it is a cluster that can be covered by the warranty....
