Hello mind14, we usually provide suggestions to issues related to Linux* distributions as best effort and we invite other Linux* users to share their comments and solutions. However, you may also want to post your inquiry in the community of this operating system distribution since the official support is through the respective developer.
Please refer to this article for a list of operating systems supported by Intel® NUCs.
The problem is that I get no display when I connect the NUC to the AV Receiver.
I had to connect the NUC directly to my TV in order to see the boot screen, update the bios and install an OS (openelec in my case).
The problem has nothing to do with the OS. I insatalled openelec as a workaround, in order to see picture through my receiver.
I played many video files but when the refresh rate is at 50Hz I get no picture!
So, NUC > Onkyo AV > TV no display at 50Hz
NUC > TV everything is ok!
Can you please tell your engineers that NUC 2820 cannot work with Onkyo 906 AV? This is happening when NUC outputs at 50Hz.
Is it possible to fix this problem with a future update of the bios?
There are no firmware updates for my Onkyo TX-NR 906.
I am using a simple HDMI to HDMI cable to connect the NUC with the AVR, if that's what you mean.
I also tried 3 different cables but no luck.
The picture that NUC outputs to Onkyo is incompatible at 50Hz (such as the boot screen). Every other refresh rate is ok.
Is this something that can be fixed with a bios update? I would like to know please...
Unfortunately the last two BIOS updates for 2820 do not fix my problem.
Is it too much to ask from your engineers to take a look at this issue and provide a solution?
My Onkyo TX-NR906 AVR is a popular model and I believe that many people would benefit...
After all, I paid for a HTPC device that I cannot use with my AV Receiver and I have been waiting for a solution since May!
Please, I would like to know if my problem is going to be resolved soon...
Just to play devil's advocate here...
The NR906 was released in 2008. That alone does not mean that it should not be compatible, but it's old enough to use an older HDMI spec. Again, that doesn't mean that you shouldn't expect it to work, but sometimes devices just don't play well together especially when they're from different generations. Many other people have no problems using their NUCs as HTPCs with other receivers. If Intel doesn't bend over backwards to make sure that the NUC is compatible with a six-year-old receiver, I don't blame them.
Also have you considered the possibility that the problem lies with the receiver itself? Maybe it cannot pass through your desired refresh rate.
Why don't you blame them? It's Intel's obligation to make sure that NUC works flawlessly out of the box, with any receiver at any refresh rate! Especially when this device is advertised as HTPC.
People who buy NUC (or HTPC) are going to connect it mainly to an AVR, no matter how old it is. If the receiver has HDMI input then NUC should be compatible with it.
When I bought 2820 the last thing I expected is having this kind of connectivity problems. I have connected my Onkyo 906 with many different devices (older or newer HTPCs, media players, dvd players, PS3/4, etc.) and I never had problems.
My AVR being 6 years old, from a different generation than the NUC, is a really poor excuse. I didn't see any warning not to use NUC with 6 years old (or older) receivers! And I shouldn't be here asking for a firmware update in order to use a device that I bought 5 months ago...
To answer your last question, Onkyo can pass through any refresh rate (24, 25, 30, 50, 60 Hz) from any device that I have connected, without problems. Only the signal from the NUC 2820 is impossible to display at that specific refresh rate (25/50 Hz).
Have you tried one or two different HDMI cables? I've come across a fair number of HDMI cables that just aren't up to the task with the NUCs. Just recently I set up a new HTPC on my workbench (720p). When I moved it to my TV (1080p) it stayed at 720p. The 1080p resolution wasn't even listed. I swapped the HDMI cable out, rebooted, and it automatically switched to 1080p.
I've found more than a few HDMI cables that would work with other components, but when connected to a NUC would be problematic. I don't think that's a NUC-specific problem either, because I had similar cable issues with my old i7 with ATI video and HDMI out.
I'm not saying it's a cable issue, just that it's something worth testing.
