I guess the whole consumer electronic industry might need a way to work better together on standards at least for such common functionality across different sectors.

To make an analogy, if I hack together a way to attach a printer to my PC, using USB protocol, over an HDMI cable, that doesn't mean "HDMI supports printers".

I agree with most of what you say, but I'll take issue with the part about the C64. It did have the ability to output a composite video signal, but it also had split chroma/luma signalling for improved video quality. Even then video quality was more important on computers than it was on consumer video gear.
Now, I think the Atari 400/800 might have had composite only. The Timex/Sinclair TX81 had composite only.

AFAIK, DisplayPort is the technically superior standard. Unfortunately, HDMI got a head-start and is only used because to support DP only on a consumer equipment would be almost suicidal.

There is no way HDMI to be replaced by DP. The only solution is it to become royalty free and be merged with DP, but even them the connector would remain, since is WAY more common than DP. The better they can do is adopt USB C connector like there is no tomorrow and that could regain market on the consumer products, maybe.

I know of the attempts, but it is still very much divergent.
Each contemporary generation of all these protocols all use the same base SerDes available on the ASIC market for transmission anyway.

Originally posted by SyXbiT View PostI'm not an expert, so I'm happy to be corrected. It used to be that DVI was for monitors, and HDMI (because it could carry sound) was for TVs. Then DVI got support for sound. Then DisplayPort replaced DVI.
DisplayPort and HDMI both transfer sound/video and are both fairly small in size (both have mini ports as well), and both handle really high refresh rates and resolutions.
Are there pros/cons that make one better suited to TV or Monitor, or do we have two similar standards just for historical reasons?
DisplayPort is free to use.
Use DisplayPort when possible.

DP is a free standard though, so for example DP's Adaptive Sync can be implemented by every vendor, meanwhile HDMI only allows these things as vendor-specific extensions (which means others can't do it unless the vendor specifically opens it up)
