HP All-in-One Desktop PC 27-cb1000i - 686V0PA not connecting to a low resolution Projector / SmartTV

New HP All-in-One Desktop PC 27-cb1000i - 686V0PA not connecting to a low resolution Projector (EPSON EB530) or a Smart TV (AMSTRAD - IMPEX) HP All-in-One Desktop PC 27-cb1000i - 686V0PA. But it works fine while connected to a Branded LED TV (Panasonic - Samsung).

Tried many ways but the above Projector or the TV is not identified while trying Detect Multiple Display or trying to Duplicate Display.

I believe something wrong with the Graphics Display driver updated the latest driver. Contacted HP Online Support but didnt get any proper solution. Support team suggested for a format and re-installation of the OS.

It is not the problem of the Projector nor the TV. Do anyone suggest any solution for the above issue without formatting the system.... Expecting a Solution, will be appreciable if i get it at the earliest.

What is your PC 27-cb1000i (4N1Q8AV) machine ? It could be one of the following over 100 machines

For example:     HP All-in-One 27-cb1018ci All-in-One PC

They probably use SAME motherboard    https://support.hp.com/au-en/document/c08204228   which shows it has HDMI 1.4 out port. As you says, you can connect to a TV.

Did you allow your projector or AMSTRAD - IMPEX to accept source from a computer ?
