Hi we recently moved to a new home with an existing media room the house was built in 2007 and there is an existing hdmi cable for the projector in roof that can not be changed out due to finished drywall basement there are the markings on cable: LWC Digital media Interconnect E190607-E We were wondering if a cable this age would support a new panasonic 3D projector?? Thank for any help
What do you mean "in the roof"? Do you mean in the attic?
Age shouldn't matter unless it is outside. Length, gauge and whether it is High Speed or Standard Speed matters.
I suspect in this case, the answer is going to be to try it. If it doesn't work it will be obvious. If it doesn't work, then you can worry about how you are going to replace it. 3D is less bandwidth than 1080p/60, so if you can do 1080p/60 right now, you should be OK for 3D.
OK, the best thing to do is to try it. If you get a solid picture for five minutes and there are no lines or sparkles or large blocks of a single color then your cable is working. Try it at 1080p/60 until you get your 3D projector.
If it doesn't work, your only option is to run another HDMI cable (unless you have a Cat 6 connection as well). Drywall can be opened and repaired. An experienced drywaller can clean it up so you can't tell. But, hopefully it won't come to that.
If your test shows sparkles or drop out all may not be lost – you may find adding a powered extender to the Sink (Display) end of the cable run will resolve any problems the cable may be introducing!
Be careful with the Connector/cable Interface – that is where many ‘older’ cable designs physically ‘fail’ if they have been bent too tightly (over stressed), tugged when moving kit around or used as a ‘pull’ point when the cables are being installed!
Do you know what cable length the manufacturer was referring to? Does the E109607-N number indicate the cables length?
I say that because usually manufacturers certify to a cable length and then anything less than that length is usually included. Any greater than that length can be a problem since the greater the length the more errors will creep in.
You have nothing to lose by trying the cable and you might find with your length and for that particular cable that you can do a bit more (or less) than 1080p/60 with deep color off.
I have not measured it but my run is likely 25 feet given the distance between the t.v. and the location of the components. I just wanted to let Bobo generally know what the likely specs are for his cable. I am looking at upgrading some of my components and will do the old try it first before replacing, but if that does not work, do you have any opinions on Monoprice's redmere HDMI cables--30ft? I have seen mixed reviews from their customers.
The 25 foot is a big consideration for whether an HDMI cable will be able to work with higher bandwidths. The bit rate is obviously derived on the allowable bandwidth of the cable. So, a shorter cable will allow a higher bitrate (all other variables being equal). That's why the length of the cable is so important. A 4 foot HDMI cable will likely allow a much higher bitrate without error than the exact same cable at 25 feet. So, it's actually a big consideration for someone in the 25 foot range.
I now recommend Redmere for anything over 25 feet to as far as Redmere will go. The first Redmere cables from Monoprice off the assembly line had problems but the general consensus on newer cable is that they perform well. For in-wall (in-ceiling) make sure you get the CL2-rated versions.
