HANNS-G HG24DPB Startup Screen Problem

[xrad]

Hi Folks

New here.

I don't have much experience with displays mainly PC's Laptops etc.

I have a HANNS-G HG24DPB with a strange problem.

1) I disconnect the vga from the monitor while pc is on, or pc is turned off before the monitor which causes a problem with the monitor.

If the above steps are carried out when I reconnect the vga while the monitor is on or I boot up the pc and then turn on the monitor it will take up to 2 hours for the display to show the vga pc image. During this time their is a light hissing noise a bit like caps charging and discharging.

In other words if their is a live vga signal to the monitor the above happens.

Monitor works fine when I turn it on before the pc so switched on (before the vga signal reaches the monitor).

Could this be a vga card problem in the monitor?

This was tested on 3 different pc's same results.

Hope all that makes sense!!!!

Regards,
xrad

Ok I typed the above in a panic to simplify the giberish,

If the PC is switched on before the monitor it stays black
for about 2 hours with a light hissing noise then I eventually
get the pc desktop picture.

The monitor must be turned on before the pc so that the pc
desktop image shows up on the monitor straight away as
normal.

Any ideas...
