I'm about to get a new monitor and I'm stuck on what type of connector to use to hook up to my laptop (not ideal setup but its an ISP monitor so worth it). My laptop only has VGA and HDMI outputs and from what I read, it seems HDMI is better but I'm concerned about the audio ouput that is available with HDMI. The way my audio is setup is via USB skipping the onboard sound to a DAC. I'm not sure that if I use HDMI, will the HDMI audio override my USB out. I'm sure sure if I will be able to disable the HDMI audio.
And if I can't, what are the drawbacks of VGA?
If you use an HDMI to DVI, the sound won't go through as DVI doesn't support it; anyway I think you can select the output device for sound so as long as HDMI isn't selected, no problem. I would definitely go with HDMI as it is a digital connection where VGA is analog. If you want to use the VGA anyway, make sure the monitor supports DVI-A, if it only supports DVI-D, you cannot use VGA (if it says DVI-I you are ok as well, it means both).
