- You cannot use a cheap DisplayPort to DVI or DisplayPort to HDMI passive adapter / cable. DVI and HDMI outputs do not support passive adapters to DisplayPort input. Passive DisplayPort to DVI / HDMI adapters and cables will only work from a DisplayPort output (source) to a DVI / HDMI input (display). They will NOT work in the reverse configuration. A DisplayPort input on a monitor will ONLY accept native DisplayPort signals. A DVI to DisplayPort or HDMI to DisplayPort active adapter would be required to connect to it, but generally it is very difficult to find an adapter that supports >60 Hz operation.

- No, HDMI is not limited to 60 Hz. Only HDMI 1.0 and 1.1 were restricted to specific formats (which were all 60 Hz and under), but this restriction was removed in HDMI 1.2 in 2005, and HDMI has not had any hard limit on refresh frequency since then. 720p 120 Hz in fact is explicitly listed in HDMI 1.2 as a supported format, although at 1080p it was still limited to 60 Hz by bandwidth constraints. HDMI 1.3 in 2006 alleviated these bandwidth constraints, increasing it to surpass Dual-Link DVI, and 1080p 144 Hz has been allowed over HDMI ever since then.

Yes; these and many other 1080p 144 Hz monitors are equipped with HDMI 1.4a inputs, yet are still limited to 60 Hz over HDMI. This is just an unfortunate limitation of those particular monitors, it is not a limitation of the HDMI standard. Other monitors, such as the ViewSonic XG2401, the Nixeus NX-VUE24A, and the Samsung C24FG70 are also 1080p 144 Hz monitors with HDMI 1.4a ports, and they do accept 1080p 120/144 Hz over HDMI. It's purely a matter of manufacturer's discretion whether they want to implement that capability or not. Sadly, many instead choose to implement HDMI 1.4a with reduced bandwidth, presumably for cost-saving reasons.

- The long and short of it is, some displays support 1080p 120+ Hz over HDMI 1.4, some don't. It just depends on the display, so you'll need to do some research on whatever product you're considering.

But if a product doesn't support the full bandwidth of HDMI 1.4a, surely it can't be HDMI 1.4a-compliant!

- Unfortunately it still can. Support for the full bandwidth is not a requirement for a device or control chip to be HDMI 1.4a-compliant. Very few displays (certainly during the heyday of HDMI 1.3/1.4) have specs that can even use the full bandwidth, so it wouldn't make sense to require that all devices wishing to implement any HDMI 1.4 features must use a control chip capable of the full bandwidth, when virtually none of them actually need that.

Isn't the extra bandwidth in HDMI 1.3+ only used for 3D at 60 Hz per eye?

@@ -5284,7 +5277,7 @@ When the HDMI Specification "adds support" for a certain format, it doesn't mean it in the conventional sense of "adding the capability" as if it wasn't previously possible. They mean it in a more literal sense of adding supporting material to help strengthen it, by defining standardized timings for the format to help with compatibility and ease of implementation instead of leaving it purely to the vendor's discretion.

- A more obvious example of this usage of the term "support" is ultrawide formats; HDMI 2.0 "added support" for the 21:9 ratio, even though ultrawide resolutions were available before HDMI 2.0 even existed and were working just fine over HDMI 1.4a. "Adding support" in HDMI 2.0 just meant it added material to help establish standardized formats and timings, not that 21:9 formats weren't possible in previous versions. In versions prior to HDMI 2.0, ultrawide resolutions are still possible and valid, they're just implemented as a vendor-specific format, and indeed the majority of ultrawide monitors use HDMI 1.4a even though it "doesn't support" 21:9 ratio formats.
