Can't screen mirror from Windows 10 laptop to Roku Streaming Stick+

Mon Sep 24, 2018 12:19 pm

New member here and I couldn't find a current post about this issue so I apologize if I overlooked something.

I have a Dell laptop running Windows 10 Home (Version 1803 Build 17134.228) and I'm trying to screen mirror to my Roku Streaming Stick+ Model 3810 on my Vizio Smart TV.  My laptop can see the Roku streaming stick but when I try to connect it gives me an error message "couldn't connect".  I went through the steps as shown in https://www.drivereasy.com/knowledge/windows-10-cast-to-device-not-working-solved as well as updating drivers and checking settings in both Windows and Roku.  I've enabled the screen mirroring mode on Roku to 'always allow' and Roku is running the most recent Version 8.1.0 Build 4155.  I am able to mirror my Android smart phone to the Roku as well as mirror my laptop to my old Roku 3 on another television.  All devices are on the same network.

Anybody familiar with issues mirroring with the Roku Streaming Stick+ Model 3810 from Windows 10?  I'm open to any and all suggestions as I've exhausted all efforts to fix this. :?

Thanks in advance.

Windows support something called Miracast, (typo in my original post) which has specific hardware requirements on the computer. Very few computers actually meet those requirements, and although they can see the Roku they can't cast to it. As you noted, Android devices are the ones that seem to work best, as iOS devices can't cast either.

In Device Manager, Miracast is configured for my Roku Player but for the Roku Streaming Stick+, the event log shows that it 'wasn't migrated due to partial or ambiguous match.'  Now trying to find a solution for this.

Just trying to level your expectations. Very few people have successfully mirrored a Windows PC to a Roku player. Android, no problem. No idea why it doesn't play nice, but from what I've read on other forums, Windows just isn't very successful with Miracast, regardless of the target platform. But I wish you the best of luck.  :D

Thanks for the response.  Had no problem mirroring with the Roku 3 last night but no luck with the streaming stick.  I was able to delete and reinstall the stick successfully in Windows without the migration error and Windows sees the streaming stick but can't connect.

Wonder if this conversation is still active.
I have a ACER SP513-52n with windows 10 Home.
I have been able to mirror to a Roku 3 without any difficulty. However recently I bought a Roku Ultra and have problems mirroring the laptop to it. When I go to the Action Center >> Connect the Roku Ultra is visible as is the Roku 3. I select the Roku Ultra and get a "Connecting --- Follow any instructions on your device message" and after about 15 seconds get "The device couldn't connect".
The Roku" pears do not show up at all (as they do when connecting to Roku 3). All permissions on the PC and the Roku Ultra are as suggested.
My display and other drivers show as up to date. Has some protocol on Roku Ultra changed that is preventing the connection?
Thanks

I had the same results as you.  I gave up trying to mirror to the streaming stick as I've been unable to find any fixes/suggestions on the web that work.  EDITED: My Android phone can connect to the newer Roku but not my Windows 10 laptop.  They both find my Roku 3 with no problem.  That leads me to believe that there is something in the newer Roku products that doesn't play well with Miracast.

I have a Roku Ultra 4640 and am able to mirror my Windows 10 desktop to it.  However, the Miracast connection almost always fails on the first try.  In order to get it to connect, I have to toggle my PC's wifi off and then back on.  It will usually then work, but sometimes more attempts at connecting may be necessary.  I should note that my PC is in a different room than my Roku so there is no line of sight to the Roku.  That could be the reason why establishing the initial connection can be problematic for me.

In the past, after having successfully mirrored to the Roku, the mirrored desktop would freeze or the connection would drop after a while, and there would frequently be audio problems.  To try to obtain a more stable connection, I made some changes to my wireless adapter's advanced settings.  Basically, I changed the settings so the 2.4ghz band would be preferred, a 20mhz wide channel would be used (to avoid interference with a neighboring wireless node on the same channel) and throughput booster was enabled.  Doing so seemed to provided a more stable connection.

However, I noticed the connection would still freeze occasionally when I was using a bluetooth device.  Using a different bluetooth adapter eliminated that remaining interference issue.  Again, I'm dealing with a no line of sight setup, so that could why some of the changes I made worked for me.  It's definitely taken quite a bit of time for me to establish a stable connection on my Roku Ultra.  It sounds like if I had a Roku 3, it might have been much easier.

I had a similar issue streaming to an older Roku stick (bought in 2015) from a Windows 8.1 laptop - even though I had successfully streamed from it before. The laptop could see the stick but not connect to it. Various resets/reboots made no difference. But this worked:

Try going to Settings->System->Advanced system settings->network connection reset->Reset connection

to reset the connection to the router. You'll have to re-enter your router password.

I did that but it didn't help.

Re: Can't screen mirror from Windows 10 laptop to Roku Streaming Stick+

So, I thought I had tried EVERYTHING for my brand new Windows 10 laptop to connect to my brand new 55 inch TCL Roku TV. The laptop was finding my TV but I was getting the "couldn't connect" after about 30 seconds. To go straight to the one setting I found without reading that solved my "Cannot connect" problem, go to the bold red text. To go to an easy setup for a wired connection anywhere in your home, go to final paragraph.

When I went to another TV and connected my old Roku 3 box to it and changed the input to the HDMI port that Roku was plugged into, I got a message on screen asking if I wanted to allow device xxxx to connect (this is whatever the name of your device is that you are trying to connect). I selected ALWAYS (as opposed to "PROMPT" or "NEVER"). Simple enough. Now, I can connect the laptop to my smaller TV with the Roku attached. By doing this, I also ruled out the laptop as the cause of not connecting to the new Roku TV.

I checked every website/forum I could find (including the actual manual from TCL) and was failing miserably. Knowing that the problem had to be some setting buried in the TV menu and NOT in my laptop, I soldiered on. Eventually, the Eureka moment came! I have my Roku TV connected via a wired connection and my laptop on Wifi and I STILL made it work and it is flawless every time. All the information you will find online indicates that you need to have both units on the same wifi network. NOT TRUE. They simply need to be on the same network, regardless of connection methodology.

Here's my setup:
Roku TV connected to internet via wired connection (even though this isn't really necessary to accomplish what I did....the wired connection eliminates those annoying occasional 1-2 second sound drops because there's no signal interference AND the wired connection makes streaming load SO much faster than WifI). I'll explain my wired connection at the end of this post because it is not typical and was a $100 investment to avoid any cables in the wall.

Laptop set on Wifi to my 2.4 ghz connection (but I could just as easily use the 5 ghz with the same results)

Settings on Roku TV:
Settings>System>Screen Mirroring: "Always Allow" is checked (you could also use Prompt if you wanted to here but then you would always need to allow it via the Prompt on the screen)
*The setting here is what you will find anywhere you look on the web....including the TCL manual and the Microsoft website.

Settings>System>Advanced System Settings>Device Connect: "Enable 'Device Connect'" is checked. You MUST have this checked to be able to screen mirror.
*The setting here is NOT typically found in any search but the default seems to be set to Enable as I have never had to actually change this one.

Settings>System>Advanced System Settings>Control by mobile apps>Network access: "Default" is checked.
*This setting is the holy grail to making Screen Mirror work on my TCL Roku TV!!!  :D :D :D This was set to "Permissive". When I changed this to "Default" screen mirroring began to work PERFECTLY. My 17" laptop monitor duplicates to my 55" TV screen without any distortion or loss of picture quality.

I have found the most usefulness I have for this feature is simply for shared family viewing of websites/videos that do not have a casting option built in like YouTube. My son's football team uses the Hudl app for video review and there's no cast feature. By duplicating the laptop screen to the TV, we can both see things on the big screen comfortably and since the picture is the same quality but larger, we are able to easily see plays developing or breaking down. Because I am providing a public service here, I also put Chrome into incognito mode to see if it still worked. No issue at all. Everything still perfect.

About the wired connection setup: pick up the Netgear Powerline 1000 or Netgear Powerline 2000 at your local electronics store. You will spend between $75 and $110 depending on model. These will convert your existing home electrical wiring into a wired network connection between your router and wherever you plug these in. The only difference in the 1000 and the 2000 is that the 1000 has one ethernet port while the 2000 has 2 ethernet ports. So if you have a Roku TV with Xbox hooked up, you could have a wired connection to both with the Powerline 2000. Setup for me was literally "Plug and Play". Whichever model you select, it comes with 2 units inside. On one unit, plug it into the wall near your router and then connect one of the router's ethernet ports into one of the ports of the unit you plugged into the wall. Note: while the router and the Netgear unit do not need to be plugged into the same outlet the do need to be on the same circuit. Plug the other Netgear unit nearby wherever you need a wired connection. This unit does not need to be on the same circuit as the router. After plugging it in the wall, connect an ethernet cable from your device into the unit you just plugged in. After about 60 seconds, all 3 indicator lights will be solid green if connected correctly. Need to add even more ethernet ports to your home....like into a garage or a bedroom far away from the wireless router, just buy more sets of Powerlines. Just note that all units must be on the same overall electrical box to work so if you have a separate panel for a detached garage, this won't help you. For my family, we just have the one set (one connected to the router and one connected to the Roku TV). But if my kid wants to download a game to his Xbox, we just unplug the unit from the Roku TV (change the TV connection to wireless if you want to stream....if just watching non-streaming TV you don't have to do anything) and he takes it to the basement to do the download and when he's finished he plugs it back into the Roku TV on the main level.

Thank you Haptad. Your suggestion to reset the network connection worked after I had almost torn what little is left of my hair out trying to mirror to a new ROKU Ultra (old Roku had worked fine).  In Fact, thank you thank you thank you

Howdy,
Please help, I'm at whits end this evening.  Trying to get Screen Mirroring from a Windows 10 PC to work. My mother had a Roku Express, but had to dig and find out it was the 3700 from 2016 and doesn't support it.  Found Roku Media Player and was able to access my files, but subtitles didn't work.  Added to the fact the RMP wouldn't do all that I wanted it to do and the Roku was slow as snot, I purchased a Roku Ultra (4660X). It's been updated to OS 9.0.0 - Build 4142-46. It has the Screen Mirror option and my phone can connect fine.

My computer is a Windows 10 x64 (Build 1803). It uses a GTX1080 and an Asus x99 Deluxe II with Broadcom 802.11ac Wi-Fi Network Adapter. There are two ethernet ports on it, but I'm staying on Wi-fi for testing purposes as I couldn't get this to find the Roku Ultra as a Display when using Connect regardless of wired/wireless. The Windows Connect app shows ready for you to connect wirelessly (Version: 10.0.17314.1). Using PowerShell I've confirmed all wired/wireless network interfaces utilize NdisVersion 6.5 (except my VPN, which I do not have turned on).

Here's what I can and cannot do.  If I go to the Action Center > Connect, it'll search forever and never find the Roku Ultra.  If I go to the Bluetooth & Other Devices menu > Add Bluetooth or Other Device > Wireless Display or Dock,, it'll never find the Roku Ultra. Oddly enough, if I go to Devices and Printers > Add a Device, it does see the Roku Ultra as a Multimedia Device that I can't really do much with.

I have Reset the network connection on the Roku. I have reset the Roku itself. I have disabled/enabled my network adapters on my PC and fully reset the home network several times.  Suggestions Please?!

I have a Roku 2 that always found my wireless connection so I could mirror from my laptop to the tv It always worked until the windows spring 2019 update1903. Now It will find my Roku to cast to tv but when I logg off my computer I have to go through the same process again to find my roku in the bluetooth section of windows 10 settings. I want to know why it won't stay connected all the time like it used to.

I think you answered your own question. If it stopped working the same time a Windows update was applied, it's most likely the Windows update that caused it. Most likely nothing that Roku can do, as Microsoft has always been a little iffy with their support for Miracast.
