I just got my ultrafine 4k hooked up to a 2016 mpb 13 no touch bar. I noticed this row in system information: Pixel Depth: 30-Bit Color (ARGB2101010).

thought it was a 8 bit monitor.
 
Interesting. On my MacBook (Retina, 12-inch, Early 2015) the LG UltraFine 4K shows as "32-Bit Color (ARGB8888)".

Also interesting: at native res or higher, System Information shows it running at 48 Hz; lower resolutions show 60 Hz.

Are you running macOS Sierra?

The first 8 might mean something else and the three 8 after means 8 bit/color. like argb8 888. Its argb2 101010 on my mbp.

I've been looking into the Ultrafine monitors to go with my yet to arrive mbp. I was settled on the 4K until I saw it was 8 bit with the 5K being 10 bit. Why doesn't Apple put this vital info in the products page? It's a pretty huge difference between the two to not mention it. Especially when they rave on about the P3 colourspace. When you're using colour gamut as a selling point then bit depth is rather vital. Now I'm going to have to splash out for the 5K.

I wouldn't trust the product page. On apples swedish page the 5k has millions instead of billions of colors. Maybe the 4k is 10 bit.

the 4k is not 10 bit, it is 8 bit.

Could you explain this from system report then?

But the tech specs say otherwise:

This is what i think. Someone att Apple don't know the difference between million and billion.

5K iMac. Apple.com product page: millions
4K iMac. Apple.com product page: millions
5K LG. Apple.com product page: billions
5K LG. Apple.se swedish product page: millions
4K LG. Apple.com product page: millions

you're confusing pixel depth and color depth. they have different values which is why you see 30 bit in system report. the 4k only supports 16.7 million colors, not sure why you keep pushing the idea that the 4k and 5k is the same panel.

Care to explain the difference between pixel depth and color depth?

I have seen that article. Where did Anandtech get the information? Could it be the millions vs billions from apples product page?
 
This is kinda disappointing. I was looking to pick one of these up for work to set on my desk to dock. I was hoping it was 10 bit.

I am still hovering on the 5k since it has so many issues.
