Monitor does not come on

I have a new computer.

My monitor is brand new and it works.

When the computer is booted up, it does not come on.

Computer only has HDMI and a VGA connection.

Very surprised that it had no DVI output.

My monitor has VGA and DVI, but NO HDMI.

Any ideas ?

Try switching the monitor on ? Might be one where you put your finger
against the edge of the monitor . Look at the manual .

I've just had the same sort of problem when using an external monitor on
an elderly HP Pavilion ZD8000 laptop that I was given (a mighty 17"
wide-screen beast!).

Initially its own screen was obviously failing (loads of vertical lines)
- and after some use, the left half went completely blank.

Undeterred, I connected my normal (Philips) 4:3 ratio monitor to it, and
it worked find (although I did need to alter the display resolution to
suit). However. with a smaller spare LG Flatron, I could only get it to
show the initial Windows boot screen - and then it went totally blank -
showing a message something like "Unable to display these settings".

Using only the right hand side of the laptop's own screen, with some
difficulty I was able to play about with the resolution and refresh rate
- and eventually I hit on a combination where the external monitor
worked normally - except during the initial boot-up period.

I'm assuming that either the laptop or the monitor (or both) are not
automatically detecting and providing some settings which at least give
you a temporary - but usable - display - at least good enough for you
then to fine-tune things.

So, with the OP's problem, would it be worth while trying a different
monitor (if one is available)? If some usable display can be obtained,
then try a selection of different resolutions and refresh rates settings
(even if they are incorrect for the second monitor) - and each time,
swap the VGA over to the new monitor, and see if anything appears?

It turned out that the monitor connection was not all the way plugged in.
