questionshow do you stream video signal to multiple tvs at…


I've thought about running a single video out from my graphics card into a box that will split the signal (think 1 in, 4 out type of splitter/booster) and shoot that signal out as additional monitors.
The TVs all have HDMI, Coax, Composite, and Component, but no VGA/DVI.
If I went out of the computer on VGA and then in as HDMI, that might be an option, but my longest run will be close to 150 feet. Can I get send VGA that far on just a standard splitter/booster?
All the TVs are a minimum of 75 feet away.

I've also thought about options of getting a modulator and then shooting the signal out over Coax, but wasn't sure how to do that.

Any thoughts or ideas or am I missing something super simple?


I am by no means a techie, but googling 'How do you stream video signal to multiple TVs at once (same signal, in sync)?' provided a bunch of results, though many of them were dated 2 or more years ago. My first instinct would be to call a local media company that does commercial & corporate video systems and pick their brains for a few minutes. They can probably point you in the direction of some starter components, and will likely want to sell you stuff if they have it. The advantage will be their experience and direction toward current technology.


I have not tried this but

Find a HDMI splitter that will broadcast 3+ at the same time, plug this in at the PC and use HDMI to Cat5e extenders.
If you do this and it works please post a new 'question' saying it worked and what you did with any problems you had. extenders


Same signal in sync to me says ATSC RF Modulator. That is, have your own virtual HDTV channel. Antenna cable is much cheaper than anything but network cable, and you'd stay in perfect sync and at high quality. Connect it to the video output of the computer that's playing the video.

It's an expensive device, somewhere between $500-1000 is what I'm seeing. But it would be really easy to add additional TV's. The ChannelPlus 5415HD is the cheapest one I can find, but it only has component input (which isn't a terrible choice, but fewer computer video cards output to that).


@caffeine_dude: This is the best and cheapest answer. Split the HDMI signal into 2 ethernet signals, then run the ethernet (not a problem at all with a 150 foot run) to the remote TVs, then convert back to HDMI at the display. Easy-peasy.

EDIT: The J6 types did this for the big displays at the JOC. Worked great.


@wilfbrim: That would be a slightly better picture quality than my option. But looking at the cost, it's about the same, possibly more expensive.


@zippy the pinhead: Yes, I've spent a few hours researching different things -- agreed, most of it was from a few years ago.
I put out a couple of feelers to some tech companies last night and I'm awaiting call backs on those. We've worked with a local A/V company before -- I think I'll give them a call or stop over today or tomorrow.

@caffeine_dude: Thanks for the link to the HDMI over Ethernet Extenders. I've debated this too, seems to be a lot of mixed reviews to include things like screens blacking out for a few seconds every couple of hours. Not sure if that's isolated to some bad components or something else. Either way, possibly a good option.

@omnichad: Exactly. I was looking at something like the ZvPro 280 ( as a potential option. I have a call out for current pricing. This seems like the most simplistic option.


@wilfbrim: Thanks. I've seen two different styles of converters. There are some that seem to push it over just 1x CAT6 line and some that seem to require 2x CAT6 lines.
Have you used either, or any recommendation on which would be better?
This uses 2x CAT5e/CAT6 lines:

This is an all-in-one splitter and Extender, but only uses 1x CAT6 line.


@sgrman05: screens blacking out would be due to dropouts in signal. This might be dependent on the quality of the cabling or going over the max distance.


@sgrman05: the following experience likely does not apply directly to your situation, but it illustrates why taking advice from a qualified expert is key...

Several years ago a big international company I used to work for wanted 3 big glorious flat panels in prominent locations in the building to display the latest company ads, sales, etc... + DirecTV/video conference smaller flat panels in all the conference rooms. Cost was not an issue. Over a million $ later we had 3 beautiful huge Panasonic Plasma displays (don't recall whether they were the 103's or 150's but they cost close to $70K EACH).

You can imagine the nasty burn-in (not really a problem if you take care of a Plasma) when static sales charts were left in place for 12 hours straight day after day. A self-important corporate clown had heard that Plasmas had the best picture (they do, but for the right functions) so he over-rode the concerns of our very experienced A-V consulting firm.


@omnichad: that's an option i've been wondering about for a few years.
I have a Couple TB's of Video on my PC, and would like to basically set up an in-house station,complete with "broadcast schedule"(while not broadcasting a signal to anyone outside these 4 walls.)
something i could keep very senior end user friendly. (tune to this channel @ this time kind of thing) but was hoping for a Shoestring Budget.. no such luck.


I have installed many HDMI extenders, some using cat6, some using 2 cat5. Sometimes they work, sometimes they don't even when using them within correct distance on tested cables, Turning the resolution down to 1080i or 720p has always solved the problem for me.
