USB <span style="white-space:nowrap">Type-C</span> to DisplayPort adapters operate passively via the <i>USB <span style="white-space:nowrap">Type-C</span> DisplayPort Alternate Mode</i> protocol, which allows native DisplayPort signals to be sent through the USB <span style="white-space:nowrap">Type-C</span> interface. These adapters do have a chip inside to negotiate the initial USB connection and switch the host port to DisplayPort output mode, so it is more expensive than a typical passive adapter, but there is no active format conversion involved with the actual video transmission.<br /><br />

No. Although this is not theoretically impossible, it is practically impossible at the moment, as there are no adapters (at the time of writing) from DVI or HDMI to DisplayPort that are capable of 120 Hz. DVI/HDMI to DisplayPort adapters are uncommon and unreliable even for standard 60 Hz video.<br /><br />

Yes. An <b>HDMI to DisplayPort</b> active adapter is required. Please note this is <b>NOT</b> the same as a <b>DisplayPort to HDMI</b> adapter. Standard DisplayPort to HDMI adapters are for connecting DisplayPort sources to HDMI displays, not for connecting to DisplayPort displays.<br /><br />

Please note that the inexpensive DisplayPort to HDMI and DisplayPort to DVI adapters and cables that can be commonly found will only function from a DisplayPort source to a DVI/HDMI display. They cannot be used to connect a DVI/HDMI source to a DisplayPort display. A much more expensive converter device is required for this, and I do not know of any that support >60 Hz video.<br /><br />

For example, if you want to know whether or not DVI ports can support passive adapters to VGA, DVI being a digital format doesn't have anything to do with VGA adapter support, because the DVI format isn't being used when you're using a passive adapter. The correct question is, "are DVI ports capable of sending VGA signals instead of DVI signals?", and the answer is "yes, if it's a <span style="white-space:nowrap;">DVI-I</span> port". Thus, passive DVI to VGA adapters are possible, despite the DVI format itself being digital.<br /><br />

Likewise, if you want to know whether DisplayPort to VGA passive adapters exist or not, asking "is the DisplayPort format digital or analog" is completely irrelevant, because there aren't any DisplayPort signals involved when a passive adapters is used. The question is "are DisplayPort ports capable of sending VGA signals instead of DisplayPort signals?", and the answer is "no", so DisplayPort to VGA signals are therefore not possible. It has nothing to do with the DisplayPort format being digital, DisplayPort simply wasn't designed with the ability to alternatively send VGA signals, while DVI was.<br /><br />

There are no rules of thumb, like "digital to digital is possible passively, analog to digital isn't". The compatibility of passive adapters is completely arbitrary and just comes down to what capabilities each video standard was designed with.<br /><br />

Please note that the convention for talking about mixed display interfaces is "[source] to [display]", so for example the term "DisplayPort to DVI adapter" means an adapter that connects a DisplayPort output (PC/laptop/etc.) to a DVI display, not the other way around. Most adapters are not reversible, so a DisplayPort to DVI adapter is not the same thing as a DVI to DisplayPort adapter.<br /><br />
