Any issues running a 10m HDMI cable

[richatnort]

Afternoon all,

I am wanting to move my PI with Kodi on it to a shelf under my Stairs and therefore need to run something to the TV for it. I've been looking at HDMI extenders over Ethernet and although they are fit for purpose i'm not wanting to spend that much especially if i want up to 4k quality through it so i'm looking at a simple option of just running a 10m HDMI cable from my PI under the stairs directly to my TV.

I am just wondering if there would be any major quality issues by doing this or is this distance OK for running up to 4k content down it? Again if there are other options to what i've mentioned that will do the job for a relatively cheap price please let me know and no keeping the PI where it is won't be a great option for me.

I use a 10m HDMI for my 1080p projector, not noticed any issues at all

I use a couple of HDMI extenders via Cat6 but don't use 4K, only 1080p

I use a couple of cheap powered ones from Amazon, but I'm finding I sometimes see a drop in signal, so I'm thinking about upgrading them to HDBT ones which are meant to be better (about £100)

10m is pushing it for 4k but you might be lucky.

And I know you said that you didn't want to keep it where it is, but is mounting it to the back of the TV an option e.g. https://www.modmypi.com/raspberry-pi/cases-183/ras...

Yeh i've seen these but i'm also getting a new TV and will be watching 4K content through the PI too using my NAS and for now don't have a spare £100 for some decent extenders so thought i 10m cable would suffice

Yes thought about this method and seems the most logical but it would mean getting power up to the TV, then hiding a 1m HDMI cable, etc and with everything else being stored under the shelf i kind of want a everything in one place solution for my OCD haha.

OCD aside, there's a good chance you can power the Pi from a USB port on the TV, and you can get really short (30cm) HDMI cables as well.

I've found it's hit and miss with the usb ports on TV's and depending on what you're trying to power. Have had the pi throw a low power warning on a Samsung TV that can run a firestick no problem, but on another Sony TV it's the other way round and that can run the pi but not the firestick.

Definitely worth a shot though!

Ah OK i may look into that then I think also reading about HDMI cables now a HDMI 1.4 which supports 4k shouldn't have a problem over 10m and for £14 on eBay i think it's worth a punt.

I think you will be very lucky to get a consistent 4K signal with a 10 metre HDMI cable. I struggled with 7 metres and have replaced it with a CAT6 ethernet option, though eventually I'll go for an optical cable. I'm mostly only sending 24Hz signal too, if you send 50/60Hz and at higher bit depth (ie 4:4:4) then you'll be at the full 18Gbps bandwidth, which will test any cable, let alone a 10 metre long one.

You need an Active Hdmi cable and you can get them 4k rated too. if you need longer then you will need an extender kit over cat6a (HDBT) you can get hybrid fibre HDMI cables but the cost takes it upto the extender kit area.

I would look at Fibre HDMI leads for 10m at 4K to garantee that you can run full fat 4:4:4 and HDR.

Just be cautious that you get them running in the right direction.

Make sure you test the cable first before you install it, if you're going to run it through walls etc I'd run in a CAT6 alongside, incase the HDMI cable ever fails.

I would check if the pi will even output a 4k signal. i use an HDanwhere active 4k cable for my sky q box over 15m that works well. you are looking about £40ish for the cable
