AM350M-HDV Problem with HDMI output

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi!
I have a AM350M-HDV motherboard with AMD Ryzen 2400G processor. 

I built myself a computer with this motherboard and two memory modules 4GB DDR4 2400 Crucial.

My intention is to leave this machine connectet to a TV by HDMI, not using VGA port, but it doesnt work properly. Sometimes everithing is fine, but in many occasions, when I turn on the computer it shows noting in screen until Windows load (normaly you can see Asock Splas an boot options). When this happens resolution gets stuck in 640x480 and there is no way of changing it. Also, sound doesn´t work, as no digital output connection is recognised. If I change some parameters in BIOS it boots properly a couple of times, but after that it fails again.

Things I tried:
-Changed several paremeters in BIOS (now is at default). Bios version: P4.90
-Changed TV
-Changed HDMI cable
-Replaced motherboard
-Reinstalled Windows with latest drivers from website
-Reinstalled Windows with latest drivers from AMD website

Any help?
