> The voltage level of the HPD pin is monitored by the Source Device. Upon detecting HPD high, the Source must read the link / sink status field, and if the link is unstable, read the link / sink capability field of the DPCD before initiating Link Training. When the pulse width is wider than this threshold, it is likely to be actual cable unplug / re-plug event. > (f) When the pulse width is narrower than this threshold, the Source must read the link / sink status field of the DPCD first and take corrective action. > (e) Sink generates a low going pulse within this range for IRQ (interrupt request) to the Source > (d) When a Sink Device is off, it must pull down its HPD output with ≥ 100kΩ resistor. > (c) Source Device must pull down its HPD input with a ≥ 100kΩ resistor. > (b) HPD signal to be detected by the Source Device > (a) HPD signal to be driven by the Sink Device | IRQ HPD Pulse Detection Threshold | 2.0 | | ms | (f) | | IRQ HPD Pulse Width Driven by Sink | 0.5 | 1.0 | ms | (e) | | HPD sink termination | 100 | | kΩ | (d) | | HPD source termination | 100 | | kΩ | (c) | | Hot Unplug Detection Threshold | 0.8 | | Volt | (b) | | Hot Plug Detection Threshold | 2.0 | | Volt | (b) | | Parameter | Min | Max | Units | Comments | Looking closer at Table 3-2 (empty Nom col removed, Comments col separated for clarity): To be sure, HPD assertion on "trickle" power is the monitor's requirement. HPD signal specification is shown in Table 3-2. > The HPD signal is asserted by the DisplayPort Sink whenever the Sink is connected to either its main power supply or “trickle” power. Looking at the normative language of the early DP v1.1a § 3.3 Hot Plug/Unplug Detect Circuitry: and I now see your response to an equivalent question. Ignoring the "repeater" terminology wank, that soundbite disclosed enough about the white label device's internal architecture for me to infer with confidence that even if EDID was properly implemented (the easiest part), the video interface is skimp and doesn't actually buffer frames in realtime.which means that on switch, the monitor's receiving ASIC will detect frame interruption as it starts to receive its new stream and blank for a second or two while it tries to reacquire.which is definitely not the instantaneous performance I was looking for. So use good quality cables, you'll be fine. So if you've got two 6-ft cables that pass through the KVM, it is like as if you have one 12-ft cable, and while one 6-ft cable might work, 1 12-ft cable will not because.(Jedi hand gestures).repeater. Like you go on Amazon, you order a DisplayPort cable, it doesn't work, and it's like, "Well, I have two DisplayPort cables that work independently, but when I plug both of them into the KVM, it doesn't work." The KVM doesn't have a repeater. > Most of the support on (their DisplayPort 1.2 KVM offering) have been down to bad or dodgy DisplayPort cables.
