Hey @ric4001,
Thank you for letting us know more about your goals.
Yes, an HDMI extender solution will improve video quality.
HDMI is more modern and reliable when compared to VGA. An extender will transmit both video and audio and support higher resolutions. This may help if you are considering a 4K projector.
Review our HDMI Extenders or HDMI Cables and Adapters. We have boosters, extender kits, passive extension cables, and active extension cables. There are various length and resolution options.
We do not anticipate issues using an HDMI extender with a standard HDMI to VGA converter. Do use a converter that has supplemental power. Not all HDMI extenders will provide full HDMI power for a converter.
I am curious how you choose to proceed. Let us know if there is more that we can do to help!
