No hotspots around me. I've got 18 gbs with Verizon so if I need to I can use some of that I'll just have to monitor that so I don't go over. I also have a 4k tv and I heard dish was suppose to have some 4k content. I'm guessing it hasn't come out yet.
So if I can use dish anywhere in my network maybe I don't need the 3 receiver. I could just cast my phone or tablet to the 3rd tv.
Unless someone knows of a way to achieve this, you can NOT cast DishAnywhere from a mobile device to a TV, at least not an approved method, and I don't think talk of hacks regarding this would be allowed here.
Dish is set to release some sort of NEW feature that will replace the Virtual Joey: a Wally, I think. From FCC filings, it seems like it may be some form of "mirror casting" that allows a Hopper or Joey to be mirror cast to another TV in your home,
but what this new Wally feature will actually do is not known, but it is coming--soon? I don't know when other than what was filed at the FCC.
However, if you don't want to wait, you can use a Slingbox to Sling video to an HDTV using an Amazon Fire TV, which includes the FREE Slingbox App that Slings within your LAN for excellent full HD PQ. Ideally, you would want to use the analog connections such as component video for HD quality (or even the SD composite will work but is inferior PQ and aspect of HDTV channels), to the Slingbox so that you can view all channels regardless of HDCP. The HDMI connection is HDCP compliant and, on Dish, will not sling video from
ALL Disney owned channels (this includes ABC Family, ESPN, et al.) HBO, Showtime and Movie Channel at the least that I know of; there may be even more channels slammed down by HDCP via Dish I don't know about. So stick to using the analog connections.
Don't bother using the Roku for Slinging to a TV in your situation (the Sling App is FREE on Roku, as well) because the video is sent OUT to the internet and then back in. Further, the Roku device requires that it be initiated using a mobile device and then "cast" via the internet to your Roku connected to your TV, and then the Roku remote is DEAD except for the HOME key. All remote controls of the Slingbox/DVR/Dish box is using the mobile device as the remote control, but you can do other tasks on the phone or tablet while it is "casting" (via the internet) to your TV.
Keep in mind that while you are using the Slingbox, another person can not use the box the Slingbox is connected to because the Slingbox operates the DVR/Dish box as if you were there in the room controlling and watching it. The Slingbox within your LAN will NOT negatively affect your bandwidth or data-cap because the video is being Slinged within you LAN (home network) and never goes out to the internet, however, I think at start of session, a very small signal is sent to the Sling servers to verify your account, but that is a minuscule amount of data, but then again, if you don't have some form of internet for the verification, you won't be able to Sling even if it is only within your home network/LAN. That was a stupid change they made some time ago, but Slingbox does work great. I use it for LAN and remote locations and can be viewed on PC's, laptops, and mobile devices, as well.
The Roku and Amazon Fire TV are now the ONLY connected devices currently supported by Slingbox (Roku and Fire TV are the "NEW" official connected devices that Sling is promoting, so their support is fresh and should continue for a long time). Older connected devices have reports of being buggy and not functioning as before, so don't try to go legacy for this. I can tell you the Roku works very well, but it first goes out to the internet via your upstream and then back downstream to your network.
Amazon is taking per-orders for Fire TV to be in stock next week, I think. I have ordered mine because the Fire TV Sling App is like the old experience on the WDTV which is far more intuitive for my family to use because they find the Roku method too cumbersome. My family is NOT the least bit techie and need easy simple ways of doing things. Good luck.
