Hello,
A bit of context, recently I attempted to switch around my HDDs from two different desktops because the one on this device had a higher capacity and wasn't put to use. I've been using this as my monitor because it has an HDMI input feature which is button-activated.
Not only did I open my All-in-one, but I formatted the whole drive to support a different OS.
I doubt that it is a physical issue, more rather missing software or drivers or along that line. I had opened it carefully, but I am unable to point out the issue.
When the input button is pressed, nothing happens. I've already attempted the solution listed here: Solved: HDMI Input Button not working - HP Support Community - 6955042
My main PC is unusable until it's fixed.
Please, help!
