Question Any KVM module that integrated with a simple graphics chip and virtual monitor in it?

[CESTLAVDOE]

I build a home lab with AMD CPU(no GPU in it),P40 (no output port,no DP/HDMI/DVI/VGA output port) with windows server installed in it

so basically I could only install the Windows system with another GPU that has output like DP/HDMI then install the driver for P40,then enable remote desktop and then put the P40 back on motherboard then connect to this server by remote desktop.

I really wanna a virtual screen like KVM to help with maintaining it remotely,but there has no other PCIe ports free on motherboard besides the Power consumed by modern GPU is a little bit high.

I read about PiKVM and JetKVM,Tiny pilot,they seems like all need a HDMI in for video signal capture,so they don't integrated with a internal GPU to deal with simple graphics processing other than just capture them...

but I know on IPMI on industrial motherboard it has some virtual GPU works like an integrated GPU to deal with webconsole KVM ,it might not support 3D acceleration but enough to deal with simple 2D graphics like powerup BIOS post /OS loading screen video signal output etc...

Is there any option available for home lab?

hope it's PCIe X1/X4 standard with outside powersupply,so when motherboard doesn't power up it can show some screen like MACHINE POEWROFF,when motherboard power up,it act as a second GPU to deal with simple graphics processing like a KVM...

Any advice would be greatly appreciated!

Back to 2000-2006 I remember there has some motherboard has a internal GPU that was built in north bridge,so I think that simple 2D graphics GPU should be a mature technology,I might be wrong

What are the complete specs for the system you mentioned above (make/model of all installed components)? Knowing this may help come up with possible solutions for your stated need.

Thanks,I'm using the free spare components to build my home lab,
so the system was:

#CPU
5800x3d

#GPU
NVIDIA P40

#MEMORY
16G DDR4*4 3200hz

#Motherboard
MSI B450M MORTAR MAX

> the motherboard coming with 2 PCIe X16 and 2 PCIe X1 sockets,
first PCIe X16 has P40 on it
second PCIeX16 has Raid card on it,so there only left 2 PCIeX1 sockets available



the card P40 seems got no luck to simple resolder the missing DP port components on PCB board to make it work,nvidia has cut the output from the chips from some posts,,but it still a 24G gram card can do alot DeepLearning stuff and rendering

There are x1 GPUs that might simplify what you are trying to do. For example:

wow thanks,but the driver will be conflict with P40,Pascal series requires similar GPU to share the driver in system to work,but another Pascal card is kind of waste if I wanna it only deal with video signal output...

But you've inspired me to found a PCIEx1 card like this

Deal4GO 2X USB-C 1x DP PCIe Expansion Adapter​

it's PCIE x1 slot,and it has typec,typec(DP protocol),DP on it!
But I don't know if it will hijack the signal from system booting so it can show BIOS logo/POST/OS loading screen,or it's need to install driver in OS to work,if it need driver then it's kind of useless in this case

and cards like

Dell 0WCWRN TERA 4x Mini DP PCoIP PCIe x1 Remote Access Host Card​

but I saw it has miniDP(in) on it,so it was video capture like card instead of a simple video output card?

I don't think the device will do what you need.

Note the details in the description.

just checked it again and found the DP port has IN mark on it,and its specs said it's a input port...I thought I got some luck before..

As you say, I expect most people just remote desktop into their headless server.

A device that could passthrough video could be used to circumvent HDCP copy protection, so while the monitor could be attached to a KVM each PC would still require its own GPU.

But it's not like you require high refresh rates or high performance so a HD5450 would work. If you can't find a x1 model, then any <25w PCIe card should work if you have open-ended x1 slots, or carefully crack away the back of a closed slot. If you don't want to spend the ~19w or so such a card uses, then even a USB software GPU should work and would be closest to your idea of a GPU in the KVM, only with an extra cable and of course one for each PC. Just make sure not to get the higher performance Thunderbolt/USB-C type unless you actually have that.

There are also FireMV cards in x1 available at a high price new (eBay prices seem OK). Matrox G550 and P690 cards may be commonly available in x1 but drivers only go up to Win 7 and Win 8, respectively. And there was some noise about $100 DisplayLink DL-7400 x1 cards last year but haven't heard about them since. They seem to have focused instead on using it in Thunderbolt/USB-C docking stations to allow more than three monitors on Macs.
