There is also a thread where we've been compiling additional findings. You can find it here -- http://avnet.me/ultra96_accessories
I personally use the one below. This has worked with the 2 or 3 HDMI monitors that I have tried.
CableCreation Product Number CD0095
Active Mini DP to HDMI, CableCreation 6 Feet Mini DisplayPort (DP1.2) to HDMI Cable, DP to HDMI, 4K X 2K & 3D Audio/Video, Eyefinity Multi-Screen Support, 1.8 Meters/Black
Amazon Link: http://a.co/d/i5EiEKn
Thanks for the link and suggestion. I'll go ahead and give that cable a try.
What's interesting is that the CableMatter's adapter I tried already was one of the ones listed in that post. (Cable Matters )
I wonder if it's possible that the compatibility changed between the Ultra96-v1 and v2.
The V1 and V2 should be the same. Both cases use the same ZU+ device and drive video in the same way. I thought someone on the team had tested that Cable Matters adapter with V1. I'll see if I can track that down to see which specific monitor was used and if they can try it with V2. For Cable Matters cable, I have used it successfully with V2, although I have only tried a single monitor.
I just received that CableCreation (CD0095) cable a moment ago, and it appears to work perfectly!
Good to know that there wasn't something wrong with my Ultra96.
Hello, I am having the same issue with my Ultra96 V2 board where I can get it to boot up through the light sequence but then the display never turns on. I have already purchased the recommended active mini-DP to HDMI CableCreation cable and still cannot get it to work on 3 different monitors. I even tried the reset trick after a couple minutes but that does not work either. I downloaded the SD image onto a card from avnet.me/ultra96-v2-oob as mentioned in the quick start guide. The board is also being powered with the 12V, 4A power supply sold for it.
Any ideas on ways to fix the issue or further troubleshoot would be great. It has me really stumped right now with what could be wrong compared to others whose work.
Hm, have you been able to verify that the board is booting up?
When I was running into this problem I used the Pynq image to make debugging a bit easier since I was having trouble with the wifi on the oob image.
With Pynq you can simply connect the Ultra96v2 to a computer via the micro-usb port and ssh in.
There's a pre-built image available here:
First off, thank you for responding! I am pretty sure it is. To add some context, I am pretty new to working with FPGAs, but it goes through the correct sequence of lights and shows the done light on at the end as well as the heartbeat. I also have been able to power a mouse and keyboard through it so it appears to be working other than the display. I will try it with the pynq image tomorrow. Mainly I just need an easy enough way to upload code to it from Vivado but unfortunately it seems the new board image does not have the easier ways to do this preset.
Thanks again, the PYNQ image has been working perfectly!
Be aware that the active mini-DP to HDMI CableCreation cable does not support 5.4 Gbps per channel mode and that the ultra96 has only 2 channels for miniDP out.
That cable uses a parade technologies PS171 https://www.paradetech.com/products/ps171-dp-to-hdmidvi/
martijnberger But I see:
The HDMI transmitter is compliant to the HDMI 1.4b specification and supports video formats using TMDS clock rates up to 300MHz (3.0Gbps TMDS data rate).
So why the limit of 5.4 per Channel instead of the 3.0 above?
The issue is the display port side,
the chip support RBR, HBR and not HBR2 so ( 1.62, 2.70 and not 5.40 Gbit/s per lane)
I've been trying to get the Ultra96-v2 to work with an HDMI display, and have been running into quite a bit of trouble.
The official documentation recommends Ableconn DPHD4K0AA, which doesn't appear to be available anywhere online.
Given that, I figured I'd try a different active mini-DP to HDMI adapter. The issue is I haven't really been able to get any to work.
Every time the same issue occurs: I can turn the device on, but there's never a display. However, if I wait about two minutes and press the reset button the device reboots and the display works perfectly.
So far I've tested:
2x HDMI Cables
2x SD Card Images - Pynq / Ultra96v2 OOB
Interestingly enough, on Pynq I'm able to get the display working by ssh'ing in after two or so minutes and running:
xrandr -d :0 --auto xrandr -d :0 -q xrandr -d :0 --output DP-1 --mode 1920x1080
This may also work on the OOB image, I haven't tried.
Additionally, using mini-DP to DisplayPort appears to work just fine. However, the display I'd like to use does not have a DisplayPort input.
Does anyone know how to get this working, or another verified mini-DP to HDMI adapter?
