July 20, 2025Jul 20 Hello,I am not sure in which sub-forum this specifically fits so in case I missed the right one I apologize. Also, I could not find any adequate other posts - hopefully I did not miss any.I have the situation that I would like to use my unraid server (7.1.2) as or with a Win11 VM for some remaining things where I need Windows for. The server is located in my office. It is a modified old "normal" PC. I am adding the configuration below. My wish is that I could use a discrete graphics card with its outputs to directly display on my dual monitor setup which is close by. Here is where the issue starts and I believe meanwhile that it is due to the graphics card I am using: an old Radeon 6450. When the graphics card is installed in the VM Windows 10 (multifunction on, everything seems to be correct with drivers), I do get an image on one of the outputs (DP) but not the other (DVI). But also, the resolution is limited to 1600x900 which is very low. I also tried using Rustdesk to remotely use the VM without cable connection to my monitors and it also shows me very limited resolution options.Windows 11 is not working as there is actually really no driver anymore for this graphics card (at least I could not make it work).So the main 3 questions I would have:VMs can / should generally have no issues with multi monitors etc right?is it really likely the case that the graphics card is limiting everything?if so: is there any recommendation of a very basic but more modern graphics card that should have no issues running in such configuration?(btw. I have another Arc 380 in my server for transcoding which works well - but I had actually a lot of troubles and could not make the VM work nicely with it - hence a preference for AMD for such task) I hope I didn't forget any important info.Thank you up front for the support.Model:CustomM/B:Gigabyte Technology Co., Ltd.

July 27, 2025Jul 27 Author Thank you very much for your response!I realize I indeed did not explicitly state that it is a pass-through system: yes. And inside Windows everything looks totally fine regarding drivers etc. That is why I believe meanwhile that it is "just" a hardware limitation of a super old card.It is good that you mention that AMD seems to be a bit less reliable - I might just directly buy a new card. Nothing too expensive anyhow. Actually I was considering an NVIDIA T600 as it is made for workstations and gaming etc. is anyhow not relevant so purely for Windows that might be best. Do you know if those T600 cards work well?What card do you use and do you also have the Server physically linked to your monitors?

July 27, 2025Jul 27 Author ok... wow. That is quite a lot :)Thank you once more - then I will likely got for either this T600 or a 16xx series one. T600 seems to be great because it does not require additional power.
