Guest Posted December 22, 2014 Share Posted December 22, 2014 Do modern BIOS's output to the HDMI port? I'm guessing no but just want confirmation. My relative is setting up a new PC as a present and they weren't getting a monitor signal and they told me they were using an HDMI cable. I told them they needed a DVI cable from the vid card to the monitor but wondering if I'm wrong and technology has moved forward. Link to comment Share on other sites More sharing options...
Tripredacus Posted December 22, 2014 Share Posted December 22, 2014 I guess it depends. The only one I have experience with is the Intel NUC... but then it only has an HDMI port and nothing else. :\ Link to comment Share on other sites More sharing options...
puntoMX Posted December 22, 2014 Share Posted December 22, 2014 On the systems I have and had it always showed the the same with HDMI as with VGA or DVI out. Link to comment Share on other sites More sharing options...
Guest Posted December 22, 2014 Share Posted December 22, 2014 OK thanks. I was under the false impression then. I thought maybe Windows needed to be running with the appropriate drivers. Wonder why they weren't getting any video then. I've never messed with HDMI ports as I don't own a cable and my monitor doesn't have an HDMI input but just noticed that my vid card has an HDMI out. I knew there was one on my mobo but never noticed the vid card one. If I ever get a monitor with an HDMI input will I see better quality video using that port over DVI?

jaclaz Posted December 22, 2014 Share Posted December 22, 2014 If I ever get a monitor with an HDMI input will I see better quality video using that port over DVI?That is what they (the cable sellers) want you to believe but no, it's just the same:http://www.cnet.com/news/hdmi-vs-displayport-vs-dvi-vs-vga-which-connection-to-choose/http://www.cnet.com/news/why-all-hdmi-cables-are-the-same/ The debate (if any) is whether on the relatively "low", "common" resolutions, and provided that good equipment is involved, there is an actual difference between VGA and any of the digital formats:http://www.msfn.org/board/topic/162901-computer-connections/(and no , there is nothing that you will be able to notice on a working setup). jaclaz Link to comment Share on other sites More sharing options...
Guest Posted December 22, 2014 Share Posted December 22, 2014 Ah cool. Thanks. I never new that HDMI carried audio also. Is that what this other audio device is in my device manager? I always wondered why I needed to load a driver for this "phantom" device. See pic.. Link to comment Share on other sites More sharing options...

You can "conventionally" think at DVI as "replacement for VGA" and at HDMI "replacement for DVI with a particular accent for multimedia" (less clutter because a same cable carries both video and audio). jaclaz Link to comment Share on other sites More sharing options...

GrofLuigi Posted December 24, 2014 Share Posted December 24, 2014 I had a computer (in fact, still have) where I could not get the signal from the UEFI on the monitor on the integrated card, neither with HDMI, nor through DVI (adapter). Discrete card worked. I suspect it was the monitor that didn't accept that particular signal. Link to comment Share on other sites More sharing options...
