Screen mirroring from a Windows computer is usually more of a Windows issue rather than a Roku problem. Windows has very specific hardware requirements for it to work. I have found the screen mirroring works fine from Android devices, and it's almost impossible from Apple devices. There's just no "standard" for mirroring, so everyone does it differently. If I want my PC to display on the screen, I just connect it via HDMI or VGA connections. Mirroring is just too much of a pain.
Hello, I wish to warn anyone else thinking of buying a Roku Insignia Television to not do it!!! I've contacted Best Buy and Roku. Only to confirm it doesn't work and they don't care. I have an older model Insignia that mirrored for one year and updated to never mirror again. I had to add a Chromecast stick to my Roku TV!!
I think a non-smart TV per se with lotsa ports (as needed) is the wiser choice.
As far as mirroring,
If you have a spare HDMI port on your TV then you can get a Graphics card with one as well.
I dont use Windows except virtually and even then not much.
But I think you should be looking at a hardware solution.
Thats what Ive been using hdmi to hdmi flawless
I faced an issue when connecting Windows 10 to Roku. The screen mirror was not working, I don’t know why maybe the Roku might have stuck at a limbo state.
I wasn’t sure what to do so, I simply update my Windows to its newer version but it did not work. Then I remove the paired device from Roku and then added another device.
This time it worked, Windows 10 got connected with the Roku device and I was able to screen mirror the video from the device to Roku.
Actually, I found this solution in this blog- http://www.pcerror-fix.com/roku-screen-mirroring-not-working-windows-10
For those facing the screen mirrorning that gets listed by Windows (Or Android), but when you try to connect, it hangs in a limbo state, try to link your Roku with an US Account.
I bought my Roku in USA and the screen mirror was working fine, but after I did a factory reset and linked it with an account I created in Brazil, the screen mirrorning stoped working. I tried many things and many factory resets, but nothing fixed it.
It only started working again when I used a VPN to create an US account, did another factory reset and linked the Roku with this new account.
There is probably some channel that gets automatically installed for US accounts that make things work.
The miracast screen mirroring uses bluetooth to connect. The RokuTvs come with an IR remote.
So I thought maybe bluetooth is bust on the RokuTv. I paired one of my other Roku Bluetooth Remotes and it paired fine.
When I went back to my computer the RokuTv was now discoverable. I think you need to pair at least one device in order to get it to turn on the bluetooth R/T
Hope this helps
