Hello everyone.
I would appreciate some help if possible please.
I am planning to build a budget PC with these components:
-MSI B450 MORTAR MAX
-AMD Ryzen 3400G
And I will not buy a dedicated graphic card (GPU), because I want to use only the integrated graphic card of 3400G processor (APU).

I need to connect to this configuration, 2 HDMI monitors by HDMI cable.

MSI B450 MORTAR MAX has 2 video outputs: HDMI and DisplayPort (DP).
AMD Ryzen 3400G supports video output for both: HDMI and DisplayPort (DP).

The question is: Can I work with 2 monitors in this configuration at the same time, one connected to HDMI output of MSI motherboard, and the other connected to
the DisplayPort (DP) output of the motherboard with a DisplayPort (DP) to HDMI converter?

I need that Windows 10 can detect both monitors at the same time, in order to expand desktop and I can see different images on every monitor (screen extend mode)

I tried to investigate, and I did not find if it is possible in MSI B450 Mortar Max.

Another motherboards like Asus B450 Steel Legend, have this functionality.

Has anyone this configuration?

Thanks!

Hi,

B450M MORTAR MAX with 3400G should support dual display, but I'm not sure if it will work or not with a DP to HDMI converter.
One DP + one HDMI should work without problems.

Hi Jabirikama. I am sorry but I do not have a solution to my question. I am waiting to buy components to build my PC, but I need to know if MSI B450 Mortar Max and AMD Ryzen 3400G can use HDMI and Display Port connections simultaneouly in order to work with 2 monitors in Windows 10.
Are you in the same problem? Best regards.

I am running with the same configuration. I came across your query when I was unable to connect DP -> adaptor > HDMI which didn't work. (testing, I interchanged two adaptors and two HDMI leads which didn't work, so I just bought DP -> DP. (v1.4)
All working fine as follows
I have one screen connected HDMI to HDMI
I have one screen connected DP to DP

@mcarr126b02a7 You'll need a DP to HDMI adaptor to connect two HDMI monitors. It's hard to say if an adaptor will work... better buy a monitor that supports DP.
