Haha. Yeah, that signal is definitely dying somewhere closer to the computer. You need to install something like an HDMI-Network extender pair of devices. It basically turns the HDMI signal into an ethernet digital signal.... transmits it.... then converts it back to HDMI on the other end. Honestly, it's magical and I didn't know I'd never need one until.... I needed one. Caveat, you need to power each of the devices for it to work.

I'm the same background as you (IT with interest in home theater) and had never heard of it until I read it here in this sub a few months ago. I needed to run a monitor in a public area that was over 100' from a computer yet have the display driven by a dedicated machine.

To add to this you can use an HDMI extender. You run CAT 5/6 between 2 boxes then break out to HDMI on the ends. Something like this https://www.amazon.com/J-Tech-Digital-Extender-Single-1080P/dp/B00G5RBX2Q/ref=sr_1_10?s=electronics&ie=UTF8&qid=1521811367&sr=1-10&keywords=hdmi+extender

I believe it is this one:

J-Tech Digital Hdmi Extender https://www.amazon.com/dp/B00G5RBX2Q/ref=cm_sw_r_cp_apap_WmBIdBfjdHfJm

I tried it with a couple cat6 cables, a 2' and a 140' one.

There are other ones that go longer for cheaper. It was just an example. And there are plenty of cheap HDBaseT pairs that will do 300ft. Here is one for $60. They also have a 400ft version for $130.

Its the full HDMI signal. No compression.

So I should get an hdmi splitter and split the hdmi output from the cable box to the splitter, then run 3 hdmi to ethernet extenders out to the tv's?

something like 3 of these: https://www.amazon.com/J-Tech-Digital-Extender-Single-Certified/dp/B00G5RBX2Q/ref=sr_1_3?s=electronics&ie=UTF8&qid=1509549170&sr=1-3&keywords=hdmi+cat6

and 1 of these: https://www.amazon.com/Splitter-Movcle-Adapter-Powered-Certified/dp/B0180PPTNO/ref=sr_1_3?s=electronics&ie=UTF8&qid=1509549474&sr=1-3&keywords=hdmi+splitter+1x3&dpID=311IVhqkBhL&preST=_SX300_QL70_&dpSrc=srch

There is definitely a solution. What you need is a balun at both ends. A balun will let you stream HDMI or audio or both over your ethernet cabling.

Sure thing, these are the ones I use:

1080p w/ IR: https://www.amazon.com/gp/product/B0764KX3JR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The ones that support 4K are at-least twice the price basically and if you want HDR 4:4:4 and all that jazz. I hope I'm not using the term "balun" incorrectly, but they are more or less extenders.

20 meters is a long ways, most things would be not cheap - you'd probably look at some fibre. OK I just did a quick look on Amazon, not too badly priced for consumers, the ones we use at work are I think around 300$

Thank you for the links. I just want to be sure I understand the products you are linking me to. The first one is basically 2 convertor boxes and you would plug a short hdmi cable from the splitter into an input box, then in lieu of using the 50 ft hdmi cable, you would use a fiber optics cable through the wall to connect the 2 boxes together, then plug another short hdmi cable from the output box into the TV.
Would this work?

If so, it'd be kind of pricey to set it up using these as I would need 2. Any chance of getting better 50' hdmi cables fixing this?

when it comes to video scources(with todays tech) you always want to go wired. in my expierance wirelss never works and is unrelaible even in the expensive options. but hdmi to ethernet adapters are affordable like this one. ive used them before and they work well. but if your stuck on wireless, id reccomend the extron elink 100, this one uasually works if the 2 point have line of sight if they can see each other and nothing comes between them they will uasually stay connected but it is something youd have to check every time you try to use the video scource. but like i said if you want reliablilty always go wired.

Theoreticals are above 25' for signal degradation. Then it depends on the vendor and quality. I'd say 25' is your max, and anything above that you'll want to use a HDMI extender.

Something like that. I actually just installed one about a few weeks ago. Works really well!

Speakers: I have no idea. I salvaged them from a classroom like 10 years ago, installed them into this room back then, and then we stopped using them like 5 years ago. We tried to figure it out before we bought the amp, but couldn't find any useful writing on them anywhere.

Switcher: https://www.amazon.com/StarTech-com-VS221HDQ-Automatic-Priority-Switching/dp/B00IUCVUB8/
We have one of that switcher, and one from the same company that's HDMI or VGA in instead of 2 HDMI. Same behavior is in each room.

There's a selection of HDMI over Cat6 adaptors on Amazon. Apparently you can now get ones that require only 1x Cat6.

Note that these usually need to be direct cables from point A to point B. They are not ethernet so you can't run them via a switch, over WiFi, or anything else.

I would try something like this: https://www.amazon.com/J-Tech-Digital-Extender-Single-1080P/dp/B00G5RBX2Q

If you're feeling up to running some cat6 - you can always get one of these (and some cable):

If you get an extra 21.1 remote (or repurpose the current tv2 remote, just sacrificing control of tv2), you can actually program it to operate tv1. You just have to flip the little number (after taking off the battery cover) to "1" and make sure the little toggle is set to "uhf". (the benefit of this being you wont need line of site to operate tv1)

Flip open the cover on the front of your receiver and hit "system info" then hit record on your newly repurposed 21.1 remote to pair the remote with your receiver.

Yes, if you get a sling adapter you should be able to see most if not all of your subscribed channels using dish anywhere - basically it uses your internet connection to upload compressed live straight from your receiver, over the internet, to wherever it is you are - so having a decent upload speed can help - at least 250kb or so upload will work for the mobile app.

Just be aware that the 722k is pretty much an obsolete receiver at this point - the only people eligible to get it are people who have it and get it replaced because it stopped working - or customers who have the older 525 and do a migration.

An alternative is to get the hopper, but only get it for two tv's. Get a wifi joey - it costs the same per month as a regular tv and has only a one time "fee" of $25. You can then move that receiver throughout your house - just needs hdmi and power. This is usually your most economical choice if you want to pay for as few tvs as possible.

Not Wi-Fi but the best I could think of is. And bear in mind this is Totally Theorerical. You could get a pair of Ethernet over Power Line adapters (best rated you can find) and then do HDMI over ethernet with a set of converters. In Theory this should give you enough bandwidth for 4k if your electrical wiring is half decent.

normally, one of the signals will cut out just briefly enough for the desktop to detect a lost connection which makes it refresh so then the other TV (and desktop monitor) briefly flicker. I'm sorry, we haven't though to take any pictures/vids.

the TVs are 4k capable but we are happy with 1080p, which is what we have been using.

We used J-tech as seen Here for the baluns.

We did two up close tests.

One with the TV on the floor (it flickered)
and with it mounted on the wall and the desktop on a table beneath it. In the 2nd setup on the table, I think was one of the only times we didn't see it flicker.

We have tried substituting a Apple laptop using a micro display port and my personal desktop with an HDMI port and both fell victim to the TVs flickering.
