Hi, having the same issue as others on here with CAC-1010 and occasional fuzzy screen at 1440p.

Wondered if support could please send me the other firmware to try out.  I’ve emailed support, twice, and no response in 5 days now.

Thanks!

Hello Support, is there anyone monitoring this website, or the e-mail address?

I’ve not heard anything back to my e-mails.

I think they have a guy that checks the mail once per week 🙂

Cheers Joevt… I think it’s more like once every 2 weeks :/

To be clear, your issue is like that which is pictured at
https://insights.club-3d.com/thread/flickering-problem-with-cac-1510-a-and-apple-cinema-display-30-on-mac-mini-m1/

?

I don’t think that’s an issue that can be corrected with firmware.

Club-3d has not acknowledged the issue because they have no way to fix it.

That’s not the issue I’m having.

My issue is exactly as decribed in this thread : https://insights.club-3d.com/thread/qnix-2710-and-cac-1010-hdcp-on-or-off/

Oh, ok. I thought fuzzy meant everything was basically usable except for some fuzziness.

I think the snow described in that thread is more like random noise like a TV tuned between channels where nothing is visible. And the snow is coloured – not just black and white – which means all the RGB values are randomized? Like this? https://i.sstatic.net/fpBgo.gif

Description sounds right yes.  I can’t see the linked image but thanks for trying.

Can you see this?

Yeah, that’s “overlayed” over the usual desktop background and any windows that are open.

So I can still see the background but there’s all that “snow” in front of it.

Is the snow only in some open windows or all open windows? Which windows? Is It only inside windows that are supposed to contain videos from streaming apps like netflix?

It’s the whole screen.  I’ve 2 screens, one DP which is always fine, and the other is DVI via the DP > DVI adapter which is fine shortly after booting, but soon gets the “snow” effect over the whole screen regardless of any windows open on it or not.

The snow is translucent so you can sort of see the desktop and windows through the snow?

That’s a complicated effect. I would like to see a photo of that. I suppose the OS has a HDCP requirement that the adapter doesn’t meet so the OS obscures everything with that static/snow.

What display do you have? Did you check the EDID to see if it supports HDCP?

Exactly right.

I’ll see if I can take a photo next time it happens… it usually takes a few hard resets of the adapter to fix the issue (every boot) and at the minute it’s working okay so I’m loathe to make it happen again right now lol.

 

Not sure about EDID, that’s a new one for me.  Screen is a QNIX Q2710LED (first edition) that only has DVI input. 1440p / 60Hz, not overclocked the monitor.
