I recently asked Which of VGA/DVI/DisplayPort/Thunderbolt/HDMI supports all the others?. It was closed and eventually auto-deleted:
The reason given was that it was a hardware shopping recommendation.
It wasn't a shopping request, though. The question was about compatibility of display adapters and protocols. There are many precedents, including but not limited to:
- Can I connect a DisplayPort monitor to the Thunderbolt port on a Mac, and vice-versa?
- HDMI vs Component vs VGA vs DVI vs DisplayPort
- Will a VGA monitor work if connected to 9-pin serial port?
- My monitor only has DVI ports, and my laptop only has VGA and HDMI ports
- What is the difference between DVI-I and DVI-D
- how do I connect an Apple Thunderbolt display to a PC?
- DisplayPort vs Mini DisplayPort
- Etc.
My intent was to ask a question about display adapter electrical compatibility for a specific set of connectors and protocols, not to ask for some sort of product that does something.
My question is: Why was this interpreted as a shopping request and how could I have worded it otherwise?
The word "shopping" was in the first revision of this question; not to ask for a product but to explain why I was looking (I was shopping for a crash card adapter, so I was looking for info about display compatibility), since I like to give some background to questions to avoid XY situations. During that time it received one close vote, and I immediately edited it out. The remaining four came much later, when the question was in the form it was in above.
