I previously had BIOS version 0029 installed, updated it to 0035 and ran some of my tests again but there was no noticeable difference.Īlso, I repeated some tests on a different 4K Monitor I have here just 8 bit per color, no HDR), connected via Displayport. On Ubuntu, I had the xorg drivers provided by the distribution). I did all my tests with Graphics DCH Driver version 30.0.101.1660 (well, on Windows. Or, have you tested this using the DisplayPort (DP) on the Intel® NUC?Ĥ- Is the Intel® NUC running the latest BIOS version 0035 and the latest customized Intel® Graphics DCH Driver version 30.0.101.1191? If not, we recommend installing these updates and testing the behavior again. However, just to make sure I have the proper information, could you please confirm the following details?ġ- You mentioned that even videos with lower resolution than 4K were having " stuttering or frame drops", for instance, 1440p videos on Firefox*.Īre the 1440p videos you tested rated as "HDR content"? Or is this also happening with videos that are not HDR content? This is to be clear if the issue is only related to "HDR content" videos.Ģ- From the link that you provided ( KODI Samples*), could you please point out some of the specific samples that you tested? For instance, were they the " 4K HDR 10-bit HEVC and the VP9 Profile 2 HDR" files?ģ- Have you tested the behavior with another display and/or different video cables (e.g.: premium high-speed HDMI cables)? For HDR support, please only use Core products".īased on these facts, I would like to do additional research to confirm HDR support. There is a "footnote" in the document (page 12) stating: " Non-Core products may not support HDR. However, I don't see any reference to HDR support.Īlso, when checking the HDR Technical White Paper for Intel® Graphics it seems to indicate that only Intel Core™ Processors support HDR. Hello you for posting on the Intel® communities.īased on the Technical Product Specifications the Intel® NUC 11 Essential Kit - NUC11ATKC4 supports a Max resolution of 4096x2160 (4K) at 60Hz for both HDMI* and DisplayPort* (DP). So no IO limitation, no buffering or anything. Is the NUC 11 even capable of 4K video playback without frame drops? If so, what am I doing wrong?Įdit: more info on the hardware: 16GB DDR4-2933, 480GB Patriot P310, connected via RJ45 to uplink, 1Gbit downstream. All video files and youtube videos can be played smoothly on my reference system (Xeon E3-1230, GTX 1060). Good old HD content was played without any frame drops. On both setups, I was on the latest OS version and I had installed the latest available drivers. I was unable to get hardware accelleration working for Chromium and the CPU can't handle the load, as expected.All videos (even the 1440p) had noticable frame drops, worse than the local files. Getting hardware accelleration to work in Firefox was a pain, but I figured it out after some research.Would not enjoy watching a movie like this. all local files had frequent frame drops, it was very noticeable.youtube videos in Chrome were much better, 1440p content was fine, 4K content had occasional frame drops, similar to the local files.youtube videos in Firefox were really bad, even 1440p content was stuttering.sometimes more noticeable, sometimes less, but even VLC reported dropped frames in its statistics panel, so it's not just my imagination all video files had occasional frame drops.Also, I tried some 4K content on Youtube. I got some video files from, all 4K content in HEVC and VP9, with 24Hz and 60Hz framerate, tested with VLC. I managed to connect my TV via HDMI with then I did some tests with 4K content and it was. The GPU should support hardware decoding of 4K 60Hz HDR material encoded in HEVC, VP9 and other formats, which is what I planned to use it for. I recently bought a NUC 11 NUC11ATKC4 which comes with a Celeron N5105 and a Jasper Lake GT1 iGPU.
