Too late, you already said MAC...<G>
Read this thread, especially the post by Scott Pearson:
Since you were not specific on a processor, I picked one for you:
Read the "Processor Graphics" section.
Additionally, you did not read the thread I linked to, with Scott Pearson's response. So, here it is for you:
"A device called a Level Shifter Protocol Converter (LSPCon) can be used to convert a DisplayPort output stream into a HDMI output stream. These are currently being used on PC motherboards, in IC (chip) form, to convert one or more of the the processor's output channels, configured as DisplayPort 1.2 output channels, into HDMI 2.0 output channels. This overcomes (albeit at a cost) the processor's HDMI 1.4a limitation."
It only affirms my question
”Max Resolution (HDMI 1.4)‡4096x2304@24Hz“
No HDMI 2.0, no 60 Hz. In fact I couldn’t find a single CPU, any gen that supports it. Fact or fiction, what gives?
What gives is you are not reading the response above. Fact: HDMI 1.4. But, if the board uses LSPCon, it can create HDMI 2.0 output. It is up to the board manufacturer. Expensive boards may have LSPCon, cheap boards probably not.
No one is misleading anyone. The processor supports what it says it supports, and the board manufacturer supports what it says it supports. Sometimes, it is up to the end-user, such as yourself, to ask the question and do a little bit of research.
Thank you for giving me the opportunity to help you understand the confusion.
It is misleading if the gap is not up-front explained and/or the presence of an LSPCon (an imperfect workaround that bypasses native HDMI and serves up a spoofed version) doesn’t show up in System Information or is otherwise unverifiable.
However, fudging HDMI 2.0+ appears to be an industry-wide problem (outside of Intel who, to their credit, make no claims about it). Hopefully everyone will get their ducks in a row soon. The lesson for me is to stick to 1.4 for now irrespective of what’s claimed.
