Home Theatre newb. Questions about 4K, Cat5/Cat6, HDMI, etc..
 

Do you have a home theatre?

If so, can you help with some basic answers to a few questions?

We're moving into a new house next spring, I plan to have a 4K TV and 7.1 Surround in a home theatre in the basement, but want to have it pre wired. I want the TV to be against one end of the room, but the components such as the AV, DVR, Xbox & PS4 to be on the opposite side of the room.

Since the distance will be a little long, will an HDMI cable between the AV and TV still work? Or should I convert it to Cat5 ethernet? (Or Cat6?) Should I run 2 Ethernet cables instead of one?

From what I understand, Netflix will stream 4k content at about 15mb/s so a single Cat5 cable should do just fine, but someone told me that dual ethernet cables would be required, but I don't know why.

I'm also wondering about latency. If have to convert HDMI to Ethernet, there could be a delay in video which would push it slightly out of sync with the audio. Do modern AV units have an adjustment to tweak and fix this? (IE, can I delay the audio by a few milliseconds to fix the sync problem if there was one?)

Any HDMI cable will be just fine..
I don't think you are going past 100 feet..

If you endup having audio delay issues normally this can be corrected in the settings for the 7.1 system. (I can't see you having issues it's very rare and normally the stings for this are used to make the room sound stage larger not to correct time issues)..

Personally laughing at Netfix ...
True 4K stream (2160p) would be well over 15mb/s
4k @30fps, 48Mbps, AAC 121kbps
1080p @30fps, 17Mbps, AAC 121kbps
1080p @60fps, 28Mbps, AAC 121kbps,

I have a 140 inch screen i run in the bonus room. I had to run about a 27 foot hdmi wire from projector to blu ray player with no quality issues at all so you should have no problems there. Same thing with the Xbox no issues.

Just use hdmi. Run cat 6 instead of cat 5 for any network connections. Also consider prewiring some ceiling speakers for dolby atmos. Receivers are shipping with this now. This is why i went with a drop ceiling, in case i forget anything i can still run new wires.

I have a 40 foot hdmi with no issues. The redmere cables are good from monoprice for long distances.

Of course you're right, but not everyone has high speed Internet available. I do, but since many do not, Netflix probably has to compress the hell out of it just to get it down to 15mb/s.

Par, Toker, Tooth, on HDMI: Great, thanks for the info.


Yes already thinking about that. I won't be buying any hardware until next spring either but when I do I will be considering Dolby Atmos for sure. Let me know how you like yours when you get it?

it's where i go for audio advise...

hope it helps you or anyone in some way.

keep posting the updates. would like to see final outcome.

I think that acoustics are really underrated. As a musician yourself, I'm sure you understand how important they are. If I was dropping a lot of money on a great theater room, I would bring an acoustics guy out and get his input on speaker placements and padding. Of course you can always read about this yourself, but you would never be able to replicate a specialists experience.

Well maybe, but first I'm not doing all that just yet - I'm just checking in on the wiring at this stage. I want the wiring in place so that when I do start buying some hardware, that I can have as clean an installation possible.

I got a 4k tv a few months ago, but cant afford netflix... :(

home theatres usually have a 'tuning' app inside to set the sound up the way you want

yup even the $300 receiver I just bought comes with that.
VSX-824-K - 5.2 Channel Networked AV Receiver with HDMI 2.0 | Pioneer Electronics USA

I also just picked up a Samsung 55" 3D TV. I've had the 110" projection before but my current place is not that big so the 55" is perfect.

I'll step up to 4k in a few years when the price comes down and there is more to view in 4k.

Like others said just use HDMI.

That's like saying "my phone has a camera, why get a camera?"

I'll answer your questions.

never ever convert a source (hdmi ->cat)if you are concerned with maintaining quality.

hdmi cables are fine up to 30 feet, any longer you need an active hdmi cable. forget the whole deal if it needs to go 50+ feet

netflix streams to you receiver not your television. that 4k netflix signal will not be impacted by an hdmi cable connectioing the receiver to the tv.

7.1 is neat and all but you are asking for a nightmare install for very very VERY little in return. There are very few movies that take advantage of 7.1 and even then it's a very brief. I would not waste my resources on 7.1 I would spend extra on dynamite sonically matched front speakers, left right and center, then some matched lower-priced rears.

more like saying do not hire a sound engineer to come out to our place when and player will do the job :2 cents:
