Blank screen and not handshaking with graphics card even at POST. Firmware updated to 104, no change in behaviour

Just over 15 mins, normal OSD is back
Unable to get anything to handshake.
Power off and on using monitor button returned yellow OSD.
Help required. PC detects the monitor (going into display settings) but nothing will get a display

Hi Anubis,

I had something similar on my MBP.

Please change your ‘input source’ to -select automatically- then power cycle it. If the display does not show any picture, please then select the DisplayPort or HDMI source (whichever one you are using at the time).

On the second PS5 FW and all going well so far, that post was testing the first PS5 firmware which rendered my monitor useless. Thanks anyway.
