At 10' - 20' you don't even need an active cable because all it does is ensure that the signal can pass without issues past the maximum certifiable 25'.
Shouldn’t all HDMI 2.0 18gbps cables pass HDR?
OK, my question. When an HDMI cable is 2.0 18Gbps why wouldn’t it pass everything we have so far? Why is HDR a yes/no a deal breaker in the wire specs when the cables are not concerned about 2.0a or 2.0b hardware/devices.
My Monopricec 2013 2.0 18Gbps active cables pass HDR, even though it’s not listed, but deep color is. So why does it have to say HDR in the specs if deep color is listed in the specs of HDMI cables.
HDMI cable vs HDMI device can be confusing. The reference numbers of 1.4 (10.2 gbps), 2.0, 2.0a, 2.0b (18 gbps) and future 2.1 (24gbps) relate to devices/hardware. HDMI cables also reference 1.4 (10.2) and 2.0 (18 gbps) as what bandwidth they will pass. HDMI cables are not referenced as 2.0, 2.0a or 2.0b.
I found this article on Trusted Reviews, HDMI 2.0 vs 1.4: What’s the difference?
This references HDMI 2.0
“As 12-bit colour ramps-up the specificity of the colour information that goes into rendering an image, the total number of possible colours is 68.7 billion. That exponential ramping-up of data is what makes transporting 4K 12-bit such a data-heavy task.
These higher colour bit rates are often labelled “deep color”, so if you see that term you now know what it refers to. It’s this ability that unlocks High Dynamic Range, which gives you video information required to more and brighter colours.”
So, I’ll assume if a 2.0 HDMI cable passes “deep color” it also passes HDR?
Some companies (let say Monoprice) provide specs that say the cable is 2.0 18gbps. Some says HDR, some do not, when both support Deep Color?
Monoprice Ultra Slim Certified Premium High Speed HDMI Cable, [email protected]
, HDR, 18Gbps, 36AWG, YUV 4:4:4, 6ft, Black…(lists HDR) (Supports Deep Color, up to 16-bits per channel, including Sony's x.v.Color™ standard)
Monoprice Ultra Slim Series Active High Speed HDMI Cable - 4K @ 60Hz, 18Gbps, 36AWG, YUV 4:2:0, 6ft, Black…(no mention of HDR and believe it has the newest active chip Spectral7, not redmere… but I’ll reference redmere in another paragraph ). (Supports Deep Color, up to 16-bits per channel, including Sony's x.v.Color standard)
Monoprice DynamicView Active High Speed HDMI Cable - 4K @ 60Hz, HDR, 18Gbps, 34AWG, YUV 4:4:4, CL2, 10ft, Black (lists HDR( (Supports Deep Color, up to 16-bits per channel, including Sony's x.v.Color™ standard)
Does YUV have anything to do with HDR? Active YUV 4:2:0, Certified YUV 4:4:4, DynamicView YUV4:4:4
With that said, I have some Monoprice 2013 18Gbps 10 foot redmere cables with red fabric. It passes HDR, yet it’s not listed as being able to do so in the specs.
Some say, including Monoprice when I spoke with them on the phone, that my 2013 cables should not pass HDR because of the older redmere chip. The Spectal7 should which is in their new cables. Yet, Monoprices description for their Ultra Slim Series Active High Speed HDMI 18Gbps cable doesn’t reference support/passing HDR, however the DynamicView does?
