Black Screen with B580 over HDMI on older Samsung monitor

[Xul]

Hi my B580 (LE) only seems to output a black screen over HDMI on some monitors, although the particular monitor (a Samsung S24D300H just a spare monitor for testing, should be a HDMI 1.4 standard) recognizes a signal.

I first though that there might have been some hardware problem (because I didn't even see a splash screen/BIOs) after rebuilding my SFF-system, yet after I switched to another graphics card the monitor worked perfectly fine, also feeding the monitor with my Raspi 400 over HDMI was not a problem.

And to make things even MORE weird, the monitor was able to work with the HDMI-Output of the B580 when I fed him this very same signal over an adapter into the VGA port. Different HDMI cables also didn't change anything.

There seems to be some incompatibility with the HDMI output signal of the B580.

Since this is a machine for taking with me on holidays and travels this unreliability with different monitors is a major issue for me. There is no point in taking my PC when the graphics card isn't even able to display the BIOS on some monitors.

Hello Xul,

I understand that you are having display issues over HDMI with Arc B580. Please share the information below for me to address this properly.

1. What is the full model of the monitor that does not work with HDMI?

2. What is the graphics card that was used for swap testing?

3. Have you tried using higher HDMI cable version?

And also just to make this clear, the monitor is working when using an HDMI to VGA adapter?

I look forward to your response.
