Cannot find Roku Express 4K for screen mirroring on any device.

Just bought Roku Express 4K. Tried screen mirroring on both my Wi dows laptop and Android phone. Have tried all suggested tricks on the forums but still cannot find it for screen mirroring on any device.

@Rajat16 

Have you looked at Roku's Support Article "How Do I Use Screen Mirroring with My Android or Windows Device " located at https://support.roku.com/article/208754928.

Basically the configuration as stated in the above article is under Settings..System...Screen Mirroring.

Post back with more detail if still having trouble.  What exactly have you tried and what exactly are you trying to do, etc. including the steps you are using.

Re: Cannot find Roku Express 4K for screen mirroring on any device.

Hello, I have gone to the Roku device Settings>System>Screen Mirroring>set Screen Mirror Mode to 'Always allow' and Enabled 'Device Connect' in Advanced system settings. Still I am unable to discover Roku device in Windows or Android Screen mirror list.

You may have to try a few different Play Store Android apps for the mirror feature to work correctly.  Even the Android Apps that I use to cast streaming content to the Roku, including Web Video Cast, Rokify, and Castify do not screen mirror properly for me, even though an option. (Normally a box appears in the App that says no devices found).  They Cast content great, but do not mirror. (I think they are trying to use the Cast function in order to mirror, but not supported on all Androids.)

If you want to try an Android App that does mirror correctly, then try Screen Mirroring for Roku by 2kit Consulting version 1.19.21.  The free version makes you watch an ad here and there, but it is good for testing and maybe you will decide to purchase (I think $5 but not sure), if it suits your needs.  I do not regularly do a lot of wireless mirroring, but just verified that this App did mirror properly on my Ultra.  Normally I use an HDMI cable from my devices to the TV directly for any mirroring needs. (Basically extended desktop mode in a nutshell.)

I really do not use Windows anymore, except for win7 now and then, so not much help there.  Maybe someone else from the Roku community can assist with that one. Perhaps @atc98092 has some insight a to the settings needed.  I think those with win10 experience problems now and then with mirroring properly.

Wish I could be of more help.

Re: Cannot find Roku Express 4K for screen mirroring on any device.

@Rajat16 your issue sounds more like a network setting. For the Roku to be visible by other devices, the network WiFi must be able to see other devices on the network. Some routers come with this ability blocked, in the name of security. Different brands label it differently, so I can't say precisely what setting needs to be changed. But it should be labeled as allowing wireless devices to see other devices on the network. If you're using what many router label as a "guest" network,  that is almost assuredly turned on.

I haven't had an Android phone for about four years, but I could mirror the screen to my Ultra without a problem. But I had full control of the network settings, so no issues there. For Windows 10, I've only been able to screen mirror from a laptop. None of my desktops are capable of projecting to another device. I believe Windows requires a wireless adapter on the computer, even if it's using an Ethernet connection. The Miracast function isn't enabled unless WiFi is available. But my laptop projects to the Ultra just fine, and while the laptop is using WiFi, the Roku is hard wired, so they don't have to be on WiFi for it to work.
