I have a MAC plugged into my DX80 as a second screen but the picture keeps flickering or going off for a split millisecond then returning..
While the picture is on its clear and correct and running at 1080p but the flickering is every 10 seconds or so
I am sure i read this was a bug in a previous version but i am on 10-2-4-46 now and i still have the issue.
Hi Andy, There was a bug created for a issue similar to yours, however it was cancelled after we were not able reproduce it.
You have likely already seen this on the DX80 datasheet, but here are some of the resolutions supported on the HDMI input.
Supports formats up to maximum 1920 x 1080 @ 60 fps (HD1080p60), including:
High-definition inputs use progressive video formats
Ensure that the HDMI output on your MAC is using progressive scan, since using interlaced with the DX80 could cause this issue. Either that, or lower your resolution and see if that works.
yes I have hence I tried the latest Fw..
happy to get syslogs. Does the DX store them local as have not done it on a DX yet or do I need to use an external syslog server and turn on debug?
ps I don't have this issue on an Mx200 alough I know this is a different hardware / software stack as its not android based.
You can get the syslog by browsing to the IP address of the DX80. On the left, under Device Log, click Console log. Now select syslog.txt. When it opens in a new window, right click and save as syslog.txt.
We were able to replicate the issue quite similarly if not worse. Here are the details:
2015 Macbook Retina 12" (USB Type C Machine) - OSX 10.10.5
Test 1 - Macbook plugged into the DX80 via a USB Type-C Adapter to HDMI. - Lags system and flickers blue every few seconds. - Recognized as 1080p 60Hz
Test 2 - Macbook plugged into a Generic 1080p HDMI monitor via the same USB Type-C Adapter to HDMI. - No lag, No blue flickering - Recognized as 1080p 60Hz
Test 3 - Macbook plugged into the DX80 via a USB Type-C Docking Station with HDMI (OWC Dock) - Same lag of system and flickers blue every few seconds. Recognized as 1080p 60Hz
Test 4 - Macbook plugged into a USB-C > Apple VGA Adapter > VGA Cable to a Crestron HDMI Scaler (HD-SCALER-VGA-E) > HDMI out to the DX80 - No lag, No flicker.
All of that said, I believe we have distilled it down to there being an issue with data coming out of the DX80 causing the issue. As the moment we strip away the extra information that HDMI carries and switch to analog, the monitor works fine. A unit as high-end as this shouldn't need a $1000+ scaler sitting between it and it's signal to produce a passable image with a newer Macbook.
If you have any further suggestions I am all ears.

Understand that this is an old thread. I just upgraded my Mac for a 2016 Pro . I use a DX80 as an extended screen. I am seing exactly the issue that is described here. Was there ever a resolution found ?
I also realize this is an old thread but I started having this same problem with the constant flicking every 3-5 seconds on my DX80 connected to my new Macbook over the past month. DX80 is running the latest firmware version "Spark Room OS 2018-02-21 7a86dbf1037".
Any help would be greatly appreciated.
I'm also having the same issue. I'm using a Macbook Retina with the USB-C to HDMI adapter and my screen flickers every 10-15 seconds. I can confirm this is only on the DX80 (I test three of them) and is not the cable or adapter as that combination produces flicker-free image son other 1080p displays.
Exact same with me. I upgraded to 10.2.5.60 and it's even worse. My DX80 screen freezes. If I stop displaying and then start again it refreshes only to freeze again in less than 5 minutes. Back rev'd to 10.2.4.99 and now only have the flickering issue.
