4K Receivers

The HR54 Genie can only stream to 1 C61K at a time. There is no wireless C61K mini so is uses the same coax that is in use by the HR22.  If by chance the HR22 is connected to the internet with a Connected Home Adapter you need to remove it.

Not sure the projector would be supported. Requirements for a TV are HDMI 2.0, HDCP 2.2, and 60 FPS.

There isn't a 4K receiver. In fact, AT&T pushed DirecTV away from a traditional receiver setup. Hope the new co-owner changes that equipment direction.

The C61K is a Mini Genie, which is a Client. That is what you use for 4K.

Clients have no tuners or recording space of their own. If you replace the HR22 with it, then you lose 2 tuners, plus you then steal a tuner from the HR54, 500GB recording space, what is already recorded on it, and that TV becomes completely dependent on the Genie (HR54) to work.

The HR54 only supports a single TV using a 4K channel at a time, no matter how many C61Ks you have.

If you are offered the Genie-2 (HS17), say NO. Though it does support two C61Ks at a time using a 4K channel, it forbids receivers/HDDVRs from being on the account. That means every single box you have would be replaced. With those tuners, recording space, and independent reliability, that is a lot lost for barely any gain.

Unless you have more capability than you are using, I would keep your setup as it is. If you do end up replacing an HDDVR with the 4K Client, I would consider replacing the HR21. Not only is it the oldest model, but it has a smaller hard drive as the 500GB started with the HR22.

You can have up to 7 minis connected to the HR54 but only 3 at a time can watch live TV and they can all be C61Ks provide you have that many 4K TVs but there will still be the one 4K channel at a time limit.  The C61K still outputs 1080i or 1080p

Yes, the same coax will be used and if by chance the HR21 is connected to the internet with a Connected Home Adapter you will have to remove it.  The HR54 streams the tuner/recorded programs to the C61K.

The HR54 has the wireless CCK built-in to connect to your home internet. You can use a wired option instead. That is just for optional internet content (On Demand). This serves as the connection for the entire home.

Like most boxes, the C61K is wired only. The C41W and C61W are the only wireless models of Mini Genies so far, which require a wireless video bridge (WVB) on the coax to serve as the antenna to/from the main Genie to those two models.

Well 4K does require HDIM 2.0, HDCP 2.2, and 60 FPS. The C61K must be plugged into the correct port, as most TVs only have a single HDMI port that is to 4K specs.

On the C61K (the only 4K model), going into the display settings and under Resolution, uncheck everything but the highest and see if that kicks it through when on a 4K channel.

Keep in mind that DirecTV was designed specifically for a traditional TV set. There can be some unforseen quirks on either projectors or computer monitors.

Naturally the HR22 will not display 4K as is a model way before it. Though is still a good model so I wouldn't replace it with a client if suggested simply because of age. Though with it and a client on the same TV (projector), then you are paying for one more TV than you have.

If you click the ‘format’ button ONCE, a popup showing the current resolution will show.

*EDIT* I just noticed now the RC73 remotes don’t have the FORMAT button. You may need to fetch an older RC66 remote or similar WITH the format button in order to do this step.
