4K Upscaling, how does it really look?

I'm sorta on the fence when thinking about my new TV. I'm upgrading from a Panasonic Plasma ST50, I'm looking at a really nice 1080p TV or a Nice 4K TV. My main concern is upscaling because lets face it, for the next 2 years or so everything I do with the TV will be upscaled. So things that will get upscaled is 1080p content from my PC and 720p content from my gaming consoles. I have a pretty beefy video card and eventually I'll be able to do 4k gaming at 30fps, which reminds me can we currently only do 30fps at 4k right now with the HDMI Spec on video cards.

Seems like going with a 4k TV means putting up with a few years of running nothing natively.. At the same time I want to buy a TV that I will have for awhile, I'm sorta done with buying a new TV every 2 years.

I think the manufacturers have other plans for you.
I had a nice 70" Sharp Aquos 3D HDTV for 2 years and was waiting for
the satellite service and the local news remote cameras and the rest of the content to
deliver consistently good HD picture quality, then bam! 4K makes it all obsolete before
it even shakes out. I got a replacement on warranty this summer and it is a Q+, which
is supposed to deliver upscaled HD content with more vertical resolution.
It's better than the 2 year old set in brightness, contrast, resolution and it is a 240 panel.
These specs are better than the 4K sets in everything but resolution of actual 4K material.
I love it and would never see the difference from real 4K from a proper viewing distance.
Next year, Sharp is promising better color on the new generation of 4K, which I would
welcome more than the 4K, so my set will be obsolete in that way.
There is no way to stay caught up with technology, which is the flip side of progress...

4k upscaling looks really good I've seen a Sharp and Samsung brand that handled it really well. Playing games from pc at 4k 30fps does work I played a bit of tomb raider with a old video card nvidia 560ti. I much rather play at 1080p with higher fps the tv upscaler is more then fine.

I bought my first 1080p TV in 2007, a 42" set that cost about as much as the 65" UHD set I just purchased. At that time, "FullHD" was still in its relative infancy. Blurays had just come out (this was at the height of the HD-DVD and BD format wars), the new consoles like the PS3 and 360 limited support for 1080p gaming and videos and I was certain then that cable TV and satellite would soon follow. Now it's 7 years later, and the current consoles (PS4, Xbone) still have limited 1080p support (some games render at 720p, 900p, etc and upscale), and cable/satellite still primarily broadcast HD in 720p or 1080i (some exceptions for PPP or premium channels).

I'd say the industry has hardly caught up with 1080p, and there's even LESS support for 4K now than we had 1080p then.

Bluray hasn't caught up to 4K. HDMI 2.0 hardware has just showed up this year. Receivers and most TVs still don't support most of the 4K HDMI spec (HDCP 2.2 is noticeably absent from most receivers). Today's PC graphics cards can only push 2160p60 through Displayport 1.2 (which most UHD sets lack) or via quality-zapping hacks (reduced color) to squeeze the signal into HDMI 1.4's bandwidth.

Today's 4K TVs better have good upscalers, as they're going be used the vast majority of the time- and in many cases, exclusively. Currently, our only content for 4K are limited to a couple shows on Netflix, Youtube, (rather expensive) proprietary players, and a handful of movies downloaded from the internet. For gaming, the fillrate requirements alone are the limiting factor; today's PCs need multiple high-end GPUs to power games to maintain playable framerates 3840x2160 at high quality settings. Consoles? Forgetaboutit.

Needless to say, you have a while before your set is "obsolete".

I bought a close out Sony XB65X900A (last year's 4K) for a decent price. It does a very good job on 1080i content from DirecTV and pretty good on 720p from that and OTA. I learned very quickly to set the DirecTV box to native pass through and let the Sony do the upscaling. It makes a huge difference.

The real surprise is 3D content on this particular set. It is passive 3d, and since there are twice as many lines, 3D content looks really, really good on this set. It can actually display 1080p in 3D, rather than cut it down to 540.

It is a tough call, you can get a lot of screen for the money with a 1080p display. I figure on having it for years and so far, it is a good set and very happy with its HDTV upscaling.
