About 4K video...

I still haven't seen any benchmarks that show if Thunderbolt 1.2 can drive a 4K panel at 60 Hz and run storage at full speed on the same bus...

Thunderbolt 2.
Displayport 1.2.
I call the new Falcon Ridge controller Thunderbolt 1.2. Apple calls it 2.0. They didn't make the total throughput of the bus any higher, it's a kludge to bond the channels so that it would support a single 4K signal. They did this so that they wouldn't look like total idiots in releasing a new "Pro" desktop that couldn't drive the new 4K displays. It means that you can't drive two 4K displays with one controller. The leftover data bandwidth is a little higher than SATA 3.0 and about equal to the PCIe SSD in the new iTrashcan.

DisplayPort 1.3 is expected to be finalized before July and DisplayPort 1.4 is starting to show up in spec sheets. The iTrashcan is DisplayPort 1.2. Official obsolescence of it's video output is only weeks away, and they way Apple implemented it means it can't be upgraded unless they can work near magic with a BIOS update.

I think 4k is a coming reality but I don't think most people will care or need it. It makes difference on very large screen.

I agree, on both counts.

While at Video Only, a local chain, I saw a an 80" Sharp TV with the typical factory demo loop. Standing four feet away, the detail was unbelievable. The picture was vibrant and sharp, truly impressive. Some of that was the tuned-for-store , but I give credit to Sharp's near 4K resolution mojo.

Not true 4K, not even Ultra-HD for all I know, but the detail was absolutely stunning. The thing is you needed that big screen to appreciate it. 80" screens in homes won't be rare, but they won't be common either.

So 4K is yet to be on my horizon.


since it you that inspired me to get a HDTV back in 2008.

Geeeze, have we been here that long?! I hope your TV has worked out well for you.


When you upgrade it's time for me to upgrade.

LOL, well I hope you're in no hurry. It takes me a while to wrap my head around stuff choose the road best traveled.

And that often requires some backtracking.
