I have a new pc. Unfortunately, I thought that my monitor supported HDMI, but unfortunately that is not the case. The graphics card on the new PC only has HDMI and display port outputs. The screen only has VGA and DVI inputs.
Fortunately, I still have an old laptop with me that has an HDMI OUTPUT. Now my question would be, can I use this laptop as a screen?
No you can't.
I've already tried and researched, so far no success.
Just buy an adapter
No.
Buy an HDMI to DVI adapter. Then you can use your monitor without any problems.
An HDMI output is input-capable in very few cases.
I use it myself, works fine.
Better display port on DVI is own. The same
