I've got more than 50 PCs and Macs with about 125 external displays working fine now after paying attention to this issue - that's all that I've related. This "issue" goes back years - see my other post - and I used my multimeter to prove it to myself after seeing threads about this very matter on ard|Forums. Cheers!ĮDIT: I posted a couple of times in this thread, here's a link to my first post (with a screen shot) and the second one follows later in that thread: Ĭlick to expand.I'm not wrong. TB cables are IMHO not going to cut it if you want to use a newer display, and decent and compliant DP 1.2 cable will work perfectly - and there seem to be even fewer makers of DP 1.2 compliant mDP>DP cables. See this on Wikipedia: and look just below it for more on 1.2 - 1.2 allows for at least twice the throughput, and I've called that bit out in my older posts on this matter. The latter carries much more potential throughput for DP devices. Now, a warning for you and others and TB cables - the TB cables are DP 1.1a compliant, and for 4k displays you'll want a DP 1.2 compliant cable. BTW, COXOC makes the Dell cables I bought, and you'll find their retail cables are "compatible" and not "compliant". A bit of detective work led me to buy Accell cables, and now there's a NEVER associated with the rest of our Macs and PCs. All along, our Eizo displays NEVER caused problems. It led me down the path of using the script, hex editors, haxies, SwitchResX, and finally seeking advice on ard|Forums - and it was the latter that led me to pick up my multitester and to buy cables on Amazon, and that's where I found the word "compatible", as in DisplayPort 1.2 "compatible", was just more snake oil.

About the Dell cable, I have no answer for that question - one can find this issue going back years for Windows and, later, Macs, by using a web search for "Dell EDID problems" (the Ruby script on github for Macs - and lots of Windows "solutions" will pop up). If it works, I might keep it and buy a DP-DP cable for my PC, or I will return it and buy the cable you used.Ĭlick to expand.Two bits of input. First - off to the Apple store to get a Thunderbolt cable.

(Though having just said that, I suppose I could just use a full size display port to display port cable to achieve this).

If it works, I'll probably still refund it and get the cable you talk of, because I need a mini-fullsize cable as my PC uses the same cable in reverse to connect to the same monitor.
At least that way if it doesn't work I can refund it in person. Today or tomorrow I am going straight to an Apple store and buying a Thunderbolt cable. I'm going to nip this in the bud, though. However, why would Dell ship out a non-DP-compliant cable in their box? With that in mind, you now have me very, very interested. You don't quite have the same set up as me as you have a 4K display, but your screenshot seemed to show native scaling to 2560x1440 on your 4K display, which is the equivalent of me wanting 1920x1080 on my 1440p display.
If you don't want to buy compliant cables, you don't have a valid gripe IMO - with your display manufacturers or Sierra (again, read that post).Ĭlick to expand.I've just read your post, and now I'm very interested.
SWITCHRESX 4K SCALED TO 1080P LICENSE
I'll sell my SwitchResX license codes - I don't need them any more as that utility is just a hack/workaround for a problem solved by the correct cabling. FWIW, Apple's TB cables are DP-compliant, version 1.1a. I've bought several SwitchResX licenses, but don't use them any longer since I figured out it is a EDID/cabling issue. Search for, and read my previous posts about this matter. I have been extolling the use of DP-compliant for several months in these forums after having issues with resolution on Win 8.1/10 and OS X for quite some time - compliant cabling fixed this, period, on dozens of my PCs and Macs. I have *more* display options in Sierra on my ASUS, BenQ, and Dell 4k displays as I'd posted earlier this evening ( ), but I'm using DP-compliant cabling (and not the cheap, non-DP-compliant cables that shipped with my 4k displays - 4 personal and 50+ company) see my screen shot before firing off a negative reply here - I'll offer that non-compliant cabling is part of this "problem" and Apple is tightening the noose on non-compliant hardware/cabling. I don't agree with these posts' assertions, no offense intended to the posters, and there's no "bug".
