4K TV Upconversion?

[The DirtMerchant]

I seem to remember a lot of discussions back in the S&V days about Upconversion to 1080P and 1080i and 720p from DVD.
So with the advent of 4K displays I am looking for a refresher discussion.

In my theoretical system:
I have 1080p signal coming from a blu-ray connected via HDMI to a quality receiver with HDMI switching.
Then an HDMI cable connected to the 4K display.

The display will have to do the upconversion at this point, right?
Since the receiver is just a pass through? Do receivers do video upconversion to 4K? Will they ever?

Yup

Since the receiver is just a pass through? Do receivers do video upconversion to 4K? Will they ever?

Right now I'm not aware of any receivers that do 4K upconversion and considering that 4K TVs and players will have to be able to upconvert, I'd bet that receiver makers won't bother to add that ability.

I could see receiver makers adding that ability once source material in 4K becomes more common.

Displays would HAVE to upconvert it now, but what I've seen is that TV scalers can be pretty stinkin' iffy at times on anything in the lower half of the market. That's one reason why I set up my great room TV to run everything through the receiver (much as my theater does)... because the scaler in even my cheap Yamaha receiver is leaps and bounds better than that in my LG TV.

A quick check of Denon's site shows their AVR-E400 will indeed do conversion to 4K.

Their AVR-Xxxxx series will also scale to 4K, but the E400 is the cheapest they show as having that ability- at $600, that's a surprisingly reasonable spot for that capability in a receiver.
