Cannot get screen mirroring to work via direct wifi using any device

So I absolutely cannot get my Roku express to mirror the screen from any of my phone's (an LG Stylo 5 or a Moto g stylus) or my computer, which runs on windows 10. My brother has the exact same roku as me and is one room away and uses screen mirroring all the time. For some reason, whenever I try, it will say it is connected and take me to the screen where it is connecting, my devices name will be listed at the bottom of the TV and a bar will be on the TV, yet it will get stuck at halfway across, so the screen will never actually start mirroring. I've checked to see if it's updated- it is. I've turned it off and on...nothing works. I'm at a loss of what to do here. I think I may have just got a **bleep** Roku. Since I can't watch HBO max on Roku, I was hoping to st least be able to mirror it onto my screen.

Re: Cannot get screen mirroring to work via direct wifi using any device

1.) Go to Settings/System/Screen Mirroring/Screen Mirroring Devices and remove all allowed and blocked devices.

2.) Go to Settings/System/Screen Mirroring/Screen Mirroring Mode and set it (and leave it) at Prompt.  If your Roku is "always on", Restart the Roku.

3.) Disable the WiFi on your phone, re-enable the WiFi on your phone, then attempt to screen share it to the detected Roku (make sure its the correct Roku - yours, not your brother's) - be patient, connecting can sometimes take 30-60 seconds.

4.) Once connected, you will be presented with a dialog box with the following choices:  "Always Allow, Allow, Block, Always Block" - choose  Always Allow (your device will then be listed under allowed devices once it successfully connects).

5.) If you ever have trouble connecting after that, first try Disabling/Enabling WiFi on your phone - If you still cant connect, restart the Roku, then Disable/Enable WiFi on your phone and try again.

Note 1:  Since the Express is a 2.4Ghz-only device, and since Miracast (mirroring/screen sharing) prefers 2.4Ghz for negotiation, make sure your phone is connected to your wireless network via 2.4Ghz before screen sharing if you're having problems.

Note 2: Do not manually use/connect the WiFi Direct function in your phone before screen sharing (the phone's/devices screen sharing function will handle all this).

Re: Cannot get screen mirroring to work via direct wifi using any device

Okay, so both of my phone's, that I know of, don't have any screen mirroring options on them. The only way to connect them is via the manual direct connect with wifi. Is there an app that I can use that actually works? Also, I don't actually have any phone's listed on my allowed devices, it wouldn't let me put anything on there, even once the phones were connected. I don't understand the 2.4 GHz thing either. Is that what kind of wifi I'm on or ....sorry, I'm not very "techy"

Re: Cannot get screen mirroring to work via direct wifi using any device

I had a Samsung S8, and it screen mirrored with my Ultra 4640 without a problem. I had to install an app, but it's been too long and I don't remember what the app was. I no longer have any Android phone, so can't say what works now.

For Windows computers, you have two requirements that I am aware of. The computer must have a wireless adapter, and that adapter and your video card must support Miracast. I cannot mirror any of my Windows desktop PCs, as none have a wireless card. The laptop I am currently using will screen mirror with no problem to any of my Roku devices (players and TVs). 

On your Windows 10 computer, run DXDIAG and save the results. In the saved file, look for this line:

Miracast: Available, with HDCP

This is what my laptop reports. If Miracast isn't available on your computer, it will say so here, and you won't be able to screen mirror. I tried it on one of my desktop PCs, and it reported Miracast: Available, no HDCP. So if I added a wireless card to that computer, I would be able to screen mirror from it as well.
