Searching for HDMI to DisplayPort Dual-Monitor Splitter
Hi,
Is there a splitter converting HDMI to 2 DisplayPorts
Motherboard - ASUS PRIME X570-P
Specification
https://www.asus.com/Motherboards/PR...pecifications/
1 x PS/2 keyboard/mouse combo port(s)
1 x HDMI
1 x LAN (RJ45) port(s)
2 x USB 2.0
3 x Audio jack(s)
2 x USB 3.2 Gen 1 (up to 5Gbps) ports Type-A
4 x USB 3.2 Gen 2 (up to 10Gbps) ports (Type-A *)
* The USB ports under the LAN port can run at USB 3.2 Gen 2 speeds with 3rd Gen AMD Ryzen™ Processors
Thanks
Regards

I'll let you do a web search for a splitter yourself. I wouldn't use one except as a last resort There's several channels of very high frequency video signals going on there. A second monitor also doubles the current demand, inductive or capacititive load of the cables and video speeds selected could be wrong.
Consider this: X boots, and the video card says: "Hello, I'm your video card , so how fast can you go?" Then both monitors answer together. That's a recipe for disaster.

I have been searching a while before posting. What I found was DisplayPort monitor splitter to 2/3 HDMI ports, not the other way round.
"DISPLAYPORT SPLITTER TO HDMI"

You can get an HDMI/Displayport cable, and a displayport splitter, which should accomplish the same thing.

You can get an HDMI to DisplayPort adapter (or converter; one is active and the other passive), and split the DisplayPort...but you won't be able to get two DIFFERENT screens..just one, mirrored. Same with HDMI splitter. One HDMI port drives one monitor, and that's it.
You *CAN* get a dock or something else that has a video output, like another video card, but the best you can do with one HDMI is one output signal.

You can get multiple screens, side by side. Just as you can get mulltiple virtual workspaces on one monitor.

Yes, but with ONE HDMI you can get one screen. Virtual workspaces are not what the OP is asking about.
An HDMI splitter gets one signal to two monitors. HDMI to DisplayPort, then splitting THAT will do exactly the same thing. DisplayPort can drive several desktops, if that's what's going IN, but in this case, it isn't. The input signal is the limiting factor here...HDMI will only ever drive one 'desktop'. Mirroring it can be done easily. Anything more requires a second video output, whatever form that takes, whether it's a docking station, or either an external or internal video card.

Your advice noted and thanks.
The graphic of my PC comes from AMD CPU. For connecting dual monitors I must purchase a graphic card ?
Can I connect one display to ASUS motherboard and another display to the graphic card?
Or I have to purchase a graphic card with 2 DisplayPort and/or 2 HDMI?
Regards

Again, yes.

That's up to you...purchase whatever you'd like...re-read the previous replies. You can have ONE MONITOR per HDMI port...if you want three monitors and you have one port now, then you purchase TWO MORE. If you buy a card with a DisplayPort, you can daisy-chain multiple monitors off the one port.

Your choice. It may work with one attached to the mobo and one attached to the card and it may not, depending on both the mobo and the OS. I know that some mobos disable the onboard video when a graphics card is installed.
You can get a pretty good and reliable GEFORCE GTX 1050 or newer for about $80 or less if you shop a little. That card has one HDMI and two DP connections so you can attach 3 monitors to it easily. I use one in my main PC and in my second PC as well, and I use the nvidia drivers for them on linux.

Hi,
Thanks for your advice.

I wouldn't rely on the "Linux ready" label - most hardware works with Linux whether it has that label or not, and the label is no guarantee, due to the nature of Linux. It's just fluff.
That said, if this NVIDIA card has been on the market for +1 year, all's good I'd say.
