Dune HD Realbox 4K Early Feedback
« on: May 21, 2020, 08:29:51 AM »
The first test results of the new Dune HD Realbox 4K are already showing up.
https://www.avsforum.com/forum/39-networking-media-servers-content-streaming/3142112-dune-hd-realbox-4k-rtd1395-thread.html
What is really good news that nobody reported any kind of instabilities even giving the box a hard time. This is amazing for a new SOC. So porting FW the Dune way using its own GUI/OS seems to work out very well here.

It has above all a few quirks you need to know but then does more or less everything promised on its initial factory FW release including exact frame-rates, HDR10+ new SOC related goodies. Good expectation for HD Pro 4K II (Plus) which should be blazing fast compared.

Reader arrived in France very quickly ...... thanks to FUTEKO !!

Well yesterday I spent about ten hours, grinding it in all directions. I tried all the possible settings and especially watched the series and film in 4K!

My installation is special, but it is done, from readers to two diffusers, so that the image quality is at its peak (calibration with test patterns and my eyes). For me the image quality goes above all other criteria ......

Let's start with the annoying problem: the image quality, at first glance it is very beautiful, but very quickly in the interior or dark parts of a film, a 'posterization' effect appears especially on my SAMSUNG 82Q950 in 8K, Which for me is irremediable. In projection on my EPSON LASER EH LS 10000, no posterization but a curious image a bit like an almost unreal 'ghost' effect, finally not easy to explain.

This problem I compare with my HIMEDIA Q5 4K and my APPLE TV 4K, which do not have this effect on the screen ..................... so for I'm going to go 'green' for a while while waiting for the next major update, because currently there have been only two minor 'beta' ...........

And that's a shame, because the device is very responsive, stable, perfect auto framerate, reading ISO BD and BD 4K nickel, responsive cover software because on practically 4000 covers I had to search for it (very easily) Ten and about the same in the covers with film error!

So camera rather well born ................... on one condition that this image problem is corrected .............. ...... I leave him a year to know which reader I keep!

You are expecting top quality picture on the cheapest product of the line using high end products to test with? Realbox 4K is meant to score on value/money which it frankly seems to do pretty well also in your tests.

I really expect the top grade RTD1619 SOC paired with a quality power design (for optimal testing with also an adequately sized Linear PSU) to do better on the nitty gritty details. It would be nice if you can repeat your tests on such box when available.

Can you provide an example/scene from a movie so we can check that as well?

More ............ my image problem comes only on UHD HDR, because HDR does not connect and gives this curious image !!

So big problem with HDR ............ let's wait for a correction from DUNE, hoping that it comes quickly!
