Question

Acer monitors display no signal and then goes black

by Mar 25, 2020 5:27AM PDT

Hi all,
I have a dell inspirion laptop that is currently hooked up to my TV via hdmi with no issues. I bought two used Acer monitors with new VGA-to-HDMI cords. When plugged in, the monitors have an orange light on the power button. After pressing the power button twice more, a green light comes on and the "Acer" symbol is shown on the screen followed by the "no signal" screen. This screen only stays on for 1-2 seconds before powering off and going back to the orange light. This process repeats itself when trying again. I don't believe it's the laptop because it can seamlessly project to my tv each time plugged in.

Any ideas/help?

Converter . . .

I've seen a lot of those converters just don't work. VGA is an analog signal and HDMI is a digital signal. A simple cable with no conversion network will not work.

hi, thanks for the response. As a technogically challenged individual, what is the solution then? Is there none? I figured VGA-hdmi cord would work or what's the point of it being invented.
What would a conversion network look like

Another example.

There are still USB to Firewire cables yet they do not work. When folk ask how to make it use the makers reply you need a driver yet the maker does not offer said driver. A good example of products that are offered yet do not work.

If you believe your VGA-HDMI cord would work, then you get back to the seller and maker to sort it out.

Here? I agree with Coryphaeus. VGA to HDMI requires more than a cord. What we use when we need multiple displays varies with the client but if the PC/Laptop doesn't have the right output we can use a converter or more often the usual USB to HDMI video card.
