Using a DVI port to replace VGA output

[bina0910]

I have an Acer laptop. Recently, my VGA port output into a digital projector has started flickering and/or showing no connection. I've tried multiple VGA cables. I've set the output resolution to the lowest possible level. No fix.

I also have a DVI port on the laptop. I bought a DVI/VGA converter - but that has resulted in no projector display at all. Do I need to change any settings to make the DVI convertor work? Any other suggestions? I can try USB conversion, but need to display PowerPoint slides, video, and an interactive hardware/software program. Most of the specs I've check state the USB to VGA conversion is not recommended for videos.

What kind of converter did you bought ?

I bought a 24+1 male DVI to a15 pin VGA female converter plug.

What you bought is an "adapter" from DVI to VGA. What you need is an Active DVI-D to VGA, something like this : http/www.startech.com/AV/Converters/Video/DVI-D-to-VGA-Active-Adapter-Converter-Cable-1920x1200~DVI2VGAE
What is the model of your Acer?

It's an Aspire7720

OK, you have a DVI-D connector, so you need a converter like the link I gave you above.

will this converter allow me to project slides and video?

one more question. Is this a better option than buying a USB to VGA converter? Thank you so much for your help.

Yes, the same output as the regular VGA connector.

I don't know enough about these converters to give you a fair answer.
