Roon core only launches if second monitor is disconnected

Core Machine (Operating system/System info/Roon build number)

Windows 10 v1909, Dual Monitor, Dual Graphics cards (Intel HD Graphics (on-board) & external PCIe NVidia GEForce GT 710, Roon version 1.7 build 571, 16GB RAM, Intel Xeon E3-1225v2(3.20GHZ)

D-Link DGE-528T

Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)

Description Of Issue

Roon app only launches when the monitor connected to the Intel HD Graphics card is disconnected. Otherwise, it hangs and eventually declares that it’s ‘not responding’. I have a dump file created from the process if that can perhaps provide more info. I used Windbg to debug but couldn’t translate the info to something understandable at my level of comprehension.
In terms of timing, the issue has only started occurring post 571 build update. Hoping you can help locate root cause.

Many thanks

Hello @Moss_5000, thanks for the report! I am currently running 571 and my PC has 3 monitors, but I’m not experiencing this issue. Are your drivers up to date? Have you rebooted since experiencing this issue?

Hi and thanks for your message. Yes the graphics drivers are all up to date. I seem to have made some progress by shutting down the core overnight. The app now starts up OK and discovers the audio devices and zones. I am then able to select any album of choice and play it. But once I minimise the app, upon maximising it again, I am met with a blank white screen.

Any suggestions?

Are the Intel drivers up to date from Intel site, not what windows update says.

:slightly_smiling_face: yes

Hello @Moss_5000, thanks for checking that! We are seeing a few reports of this same behavior elsewhere, can you please provide the following so I can add this data with the others?

Hi Nuwriy,

Please find the diagnostic info here:

If you require any further info, please let me know.


Hey @Moss_5000, thanks for the info! I have added your details to our ticket system, we’ll be gathering data from users experiencing this so we can submit a full report to our QA team. Thank you for your patience and I’ll be back once I have more info.

Thanks Nuwriy. A quick update, I’ve managed to get a workaround.

I disconnected the second monitor within Windows, launched Roon and then minimized the app. When clicking on the app to bring it up it works just fine. I reconnected the second monitor (extend display within settings) and now the app can be minimised and maximised successfully.

Not a fix but something in the short term to get around this issue.



So both monitors are now connected to the same graphics card (NVidia GeForce). Secondary card (Intel HD built-in) disabled. Roon now launches and can be minimized and maximised without issue.

You’re probably wondering why I had each monitor connected to a seperate graphics card. As well as my desktop PC (Roon core) I also have a docking station for my laptop which also connects to both monitors via various ‘limited’ inputs. I can switch inputs on the fly depending on which device I need to use.

Hopefully that provides some insight as to the reason for the issues I’ve been experiencing. It seems Roon can’t handle multiple monitors/graphics cards.
