Hmm, interesting... Guess I'd better accelerate my plans to move to an external site

Google delisting helpful information to increase dependence on AI? ¯\_(ツ)_/¯ But could just be because it's not too active, I think they tend to prioritize newer things.

Docks are usually capable of only half the normal rate, because in order to support USB superspeed on the dock they can only allocate half of the high speed lanes for DisplayPort, the other half are used for USB. So it may support HBR3 transmission speed (DP 1.4) but only 2 lanes instead of 4. That may be the case here.

Yes, HDMI 2.2 will be added in the next update. CVT-R2 is CVT-RB v2. v3 is almost the same as v2, but overhead is slightly increased, I think it's not of too much interest to people for calculation purposes, at least not enough for me to add it right now. I'm only doing small maintenance now, not adding new features. Invision is removing the ability to post direct HTML/JS content, so this guide won't be maintainable and needs to be moved to an external website.

Can you provide a source for this measurable and tested difference?

Power factor isn't an efficiency rating, it's not wasting the difference as heat. 1000 VA / 550 W means it will support devices that use up to 550 W even with a power factor as bad as down to 0.55. But that 1000 VA capability will almost never be used because any PC power supply will have power factor correction so they're unlikely to use more than 600 VA or so at 550 W.

No, the 40-series is affected by this limitation, so you will be limited to 2 monitors in your case.

Probably the monitor uses custom timings instead of CVT-RBv2 to get a slightly lower data rate, so it falls within HBR2 limits to maximize compatibility.

V-Sync produces a frame on the vertical sync pulse, which happens once every refresh, so if you are running at 120 Hz there are only 120 vertical sync pulses per second, so it will only render 120 frames. Sounds like you want fast-sync.

Yes, for 4K 60 Hz RGB. The TMDS transmitters on RX 400 series supports up to 600 MHz since it's required for their HDMI implementation.

Should be supported on that GPU. Works fine on my RX 480. You'll just need to use the AMD pixel clock patcher to remove the driver limit. Refer to the pinned thread. https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?output=DVI&input=HDMI

HDMI doesn't have the ability to send multiple video streams from a single port.

I see. Generally this indicates a miswired DP cable, which used to a problem years ago. But I don't think Dell has ever had that issue. http://monitorinsider.com/displayport/dp_pin20_controversy.html

Where did you get the DP cable from?
