So they spent about ten hours today aligning the panels and doing firmware updates. They still have more panel alignment to do tomorrow morning. I expect they’ll start color calibration tomorrow afternoon finishing up Friday. Here’s a quick pic of the panels installed with the power off. Red lights are shining down from the top and soft white lights from the bottom and yellow wall wash lights at the side.

That looks incredibly good! - Like one large single element (just as you'd want) rather than 16 bits pressed together... How do they adjust the alignment? are there adjustment screws or similar?

This is shaping up to be something truly incredible

Ha! Good point Ptrubey - here in the UK 'Winter is coming....'

Any cooling fans (or mechanical noise of any kind) from these amazing panels?

I trust they are not done yet, as one can still see the 'squares' in the picture, i am sure they can make it look even better. Keep in mind that when installers started with the Onyx they took two weeks for the install/alignment and calibration, that should be one week now. Highly demanding applications still take time and attention.

To be completely fair I can't see the gaps here... on a medical-grade calibrated monitor, even zoomed-in - and that's with the panel lit intentionally in a way that's unlikely to happen in real use! But I appreciate you could have eagle eye-sight Donaldk, and you've been working with the best display tech for decades.

Gaps or the module/cabinet structure, two different things. I can't see the smd/circuit board structure. I can't see gaps, but the squares are visible, might be surface structure and reflection/colour variation, or something else.

I'm not sure what you're referring too as 'squares', sorry - I was looking for gaps or visible lines between the 16 individual rectangular panels (for example, there must be a joint right down the middle of both axes) - but I can't see it at all from this snap, which is very encouraging!

I can't see them either at least in that image. The important thing isn't when it isn't lit anyway but when it's on at viewing distance.

Art,
Like I reported after watching the Onyx in Houston - I walked up to this Giant 200 feet wide ONYX screen and could see hairline seams about 2 feet from the screen and at 4 feet nothing - both when the screen was lit up and not.
Samsung has nailed down the technology.

There are these sprocketted wheels on all sides that they adjust. They’ll move a panel up or sideways, make an adjustment and put it back. It is finicky and time consuming. They not only have to align it in the x and y axis but also the z axis.

Nope. The panels themselves are very quiet. Part of the reason for the vertical supports during install is to allow heat to rise up from the back. You have to make sure there is passive airflow around the completed panel.

The media box has fans, but that’s in the source rack along with all the other components that have fans.

Correct, it does not appear to support 3D.

That would make sense, this isn't something probably %99 of the population could buy and install themselves, there might be a handful AVS wise with enough knowledge to even attempt to install something like this themselves.

I’m a hands on kind of guy, but this absolutely can’t be done by a homeowner. I doubt panels of this size are ever going to be consumer installable products. They have to be split up into modules since they are too big to fit inside doorways and the like when assembled. I just can’t see technology getting that good to not require days of precise alignment plus a bulletproof backing site prep.

And yes, when the panel is off and you are a couple of feet away from it you can indeed see that each individual panel (16 panels) are themselves made up of, I think, 12 or 16 rectangles. But you certainly don’t see that when the screen is on.

TEASE.

Btw, re: the Z axis, are the panels perfectly flat to your eyes? IOW if laid down on a flat surface will all 4 corners and the center touch without any wobble? If not, then do the adjustments allow for 'twist'?

The Onyx screen is 'Prickly' in texture - how about the wall ? Prickly or Glossy like a TV?

So could you configure the panels to provide a 2.35:1 aspect ratio screen?

I don't think you would need to. The idea would be to just got the biggest 16:9 screen you can then only use necessary panels for desired AR. It wouldn't have the issues a projector has

I actually had that conversation with Samsung last year when I was considering purchasing. It turns out that 12 modules (4 x 3) gives around the same AR as 2.40:1 and also delivers the same image resolution as a 4K projector displaying 2.40:1 images!

Added bonus, you save ~$100K off the retail price.

What sort of front end is needed to feed the video signal for this though? I get using a lens to 'widen' an image to say 2.4:1, but how would that be accomplished in the scenario you outline? Sorry am not super well versed in aspect ratio changing.

Yes, but then you’d get less than 4K resolution when viewing 16x9 content. And that’s assuming the consumer version of the Samsung media box can handle such a set up (which it may, I just don’t know).

I was refering to Samsung Crew backing up Direct Sales versus 'an(y) integrator', not a DIY marketing strategy.

So after five very full days, The Wall has been installed. Most of that time was spent aligning the panels, and then doing “color calibration” which meant making sure the red, green, and blue led brightness was uniform across all sixteen panels.

It turns out the media box I got is the same one used for 8k installs. That would one huge display (4x the size of mine) and even more ridiculously expensive. But I’m sure there is some Saudi Prince somewhere...

Here’s what the media box looks like from behind. The two fibers connect to each half of my 4K panel. Then Ethernet, 4 HDMI inputs, optical out, and a 10 GBPs HDBT for connecting to a blue tooth/WiFi box near the panels.

Here are some pics. I’m still futzing with the brightness levels. It is probably too bright right now and it looks worse in these iPhone photos. Anyways here’s some content. Zootopia via AppleTV streaming. Rocket man via 4k HDR blu ray and an 8k Peru vid via YouTube streaming. The streaming is directly from the Samsung media box.
