嗨莱昂纳多
谢谢您的回复。
我已通过此ppa更新到最新的201801版本的intel图形驱动程序/ set：
更新的开放图形驱动程序：Oibaf
当我通过HDMI连接到我的飞利浦电视时，我仍然可以选择视频或声音
我看到问题与manyl用户在这些主题中提到的相同：
NUC7PJYH：HDMI 2.0支持不佳。
寻找兼容的电视（4K-60Hz-4：4：4）。
NUC7PJYH - 当HDMI UHD颜色为ON时，三星4K电视上没有信号
NUC7PJYH HDMI在特定显示屏上出现问题。
NUC7CJYH Linux / HDMI问题
英特尔NUC7PJYH：没有视频信号
所有这些线程都表明在NUC7xJYH系列中有一个带有HDMI 2.0a实现的设计缺陷，并且在将电视显示器连接到NUC7xJYH系列时会出现此错误。
此观察与OS（Windows或Linux）无关。
你/英特尔能否用bios版本来解决这个问题？
问候
Jens K.



以下为原文

Hi Leonardo
Thank you for your reply.
I have updated to the latest 201801 version of the intel graphics drivers/set through this ppa:
Updated Open Graphics Drivers : Oibaf
Still i can choose to have either video or sound when i connect to my Philips TV through HDMI

I see that the issue is the same as mentioned by manyl users in these threads:
NUC7PJYH: Poor HDMI 2.0 support. In search of a compatible TV (4K-60Hz-4:4:4).
NUC7PJYH - No signal on Samsung 4K TV when HDMI UHD Color is ON
NUC7PJYH HDMI Issue on particular display.
NUC7CJYH Linux/HDMI issues
Intel NUC7PJYH: no video signal

All of these threads indicate that there is a designflaw with the HDMI 2.0a implementation in the NUC7xJYH series and that this error is showing itself when connecting a TV display to the NUC7xJYH series. This observation is independent of the OS (Windows or Linux).
Could you/Intel please address the error with a bios release to fix it?
Regards
Jens K

嗨PeterNUC。
我想你是对的。
我决定将我的UHD电视设置为非UHD模式 - 现在运行1920x1080非UHD。
我认为英特尔营销和销售的产品无法利用英特尔自己为客户指定的规格，这是一种耻辱。
如果英特尔发布了尽快修复此问题的BIOS更新，那将是适当的



以下为原文

Hi PeterNUC.
I think you are right.
I have resolved to setting my UHD TV to non UHD mode - now running 1920x1080 non UHD.
I think it's a shame that Intel markets and sells a product that is not able to utilize the specification that Intel it self has specified to the customer.

It would be apropriate if Intel released a BIOS update that fixed this problem ASAP

我发现了一个新错误。
如果我在失败的模块后看起来我dmesg：
dmesg |
grep失败了
我发现
[2.160352] i915 0000：00：02.0：i915 / glk_dmc_ver1_04.bin的直接固件加载失败，错误-2
我已经找到了Gemini lake blob，它应该在哪里 - 在/ lib / firmware / i915中为glk_dmc_ver1_04.bin
所以文件在那里但由于某种原因它不会在启动时加载。
也许构建blob的英特尔工程师可以解决这个问题



以下为原文

I have found a new error.
If i looked i dmesg after failed modules:
dmesg | grep failed
i find

[	2.160352] i915 0000:00:02.0: Direct firmware load for i915/glk_dmc_ver1_04.bin failed with error -2

I have looked for the Gemini lake blob and it is where it should be - in /lib/firmware/i915 as glk_dmc_ver1_04.bin
so the file is there but for some reason it does not load under boot.

Maybe the Intel engineers who have build the blob can solve this issue

我想我找到了这个问题的答案。
我为Ubuntu安装了UKUU ppa并使用它来尝试不同的内核，如果一个较新的内核将加载gemini湖的i915 glk_dmc_ver1_04.bin文件
这个问题在最新的内核4.18中得到了解决
有了这个内核，Gemini lake blob就会被加载，而HDMI输出到电视的工作在UHD和非UHD模式。
我现在可以毫无问题地运行UHD 4.4.4。
接下来是让VAAPI在mythtvfrontend中工作。
Preresently我只能运行OpenGL高品质。
如果我尝试使用VAAPI，我会收到视频输出错误。



以下为原文

I think I have found the answer to this problem. I installed the UKUU ppa for Ubuntu and used it to try out different kernels to se if a newer kernel would load the i915 for Gemini lake the glk_dmc_ver1_04.bin file

The problem got solved in the newest kernel 4.18

With this kernel the Gemini lake blob gets loaded and the HDMI output to the TV works in UHD and non-UHD mode. I now can run UHD 4.4.4 without problems.

Next up is getting VAAPI to work in mythtvfrontend. Pfresently i can only run run OpenGL High quality. If I try to use VAAPI i get a video output error.

嗨Jens，
很高兴听到你碰巧解决了这个问题。
如果我理解你的话，你可以在飞利浦50PUS6262电视上以60Hz运行UHD 4.4.4。
那是对的吗？
如果是，你能说出你是如何在电视上启用4：4：4和HDMI 2.0的（默认情况下4K电视通常支持4：2：2和HDMI 1.4）。
谢谢，彼得



以下为原文

Hi Jens,

Good to hear that you happened to resolve the problem. If I understand you right, you can run UHD 4.4.4 at 60Hz now on Philips 50PUS6262 TV. Is that correct? If yes, could you tell how did you enable 4:4:4 and HDMI 2.0 on your TV (by default 4K TVs usually support 4:2:2 and HDMI 1.4).

Thanks,
Peter

延，
谢谢（你的）信息。
看起来很有希望。
你碰巧在电视上重现了真正的4：4：4色吗？
我的意思是，您确认使用4：4：4测试图像吗？
此外，你在POST期间看到NUC标志吗？当HDMI端口配置为HDMI 2.0时你能进入BIOS吗？
我问这样愚蠢的问题，因为我仍然找不到可以用作这个NUC的监视器的电视。
不幸的是，我正在运行Windows，所以我不能使用你的Linux相关信息。
谢谢，彼得



以下为原文

Jens,

Thanks for the info. It looks promising. Did you happen to reproduce true 4:4:4 color on your TV? I mean, did you verify that using a 4:4:4 test image? Besides, do you see NUC logo during POST and can you enter BIOS when the HDMI port is configured as HDMI 2.0?

I am asking such stupid questions because I still cannot find a TV, which could be used as a monitor with this NUC. Unfortunately, I'm running Windows, so I cannot use the your Linux-related info.

Thanks,
Peter

嗨彼得。
NUC显示了POST中通常显示的内容并在linux中启动 - 一切都在那里 - 并且功能通常没有错误发生。
我不认为我有4：4：4的图片来测试。
我只是假设，因为电视显示视频和一切看起来（几乎）如预期的那样是4：4：4
你能给我发一个这样的视频或图片的网址吗？
当我写（几乎）时，使用VAAPI时的CPU使用率有点高。
我在Mythtv中由VA模块引起的事情并没有编译为NUC的正确VA lib版本。
我用：
0.29：“Mythbuntu团队”团队
我读到的一些正常的ubuntu多元宇宙Mythtv是为我的VA模块编译的。



以下为原文

Hi Peter.
The NUC shows what is normally shown on POST and boot in linux - everything is there - and functions normally with no errors occurs.

I do not think that i have a 4:4:4 picture to test with. I just assumed that since the TV shows the videos and everything looks (almost) as expected that it is 4:4:4

Can you send me a url for such a video or picture?

When i write (almost) i se that the CPU usage when using VAAPI is a bit to high. I thing that it is caused by VA module in my Mythtv is not compiled for the right VA lib version for the NUC. I use the:
0.29 : “Mythbuntu Team” team
Somewhre i read that the normal ubuntu multiverse Mythtv is compiled for my version of VA module.

嗨彼得。
我可以下载图片并显示全屏我的Ristretto（Xubuntu Paint替代品）。
我可以清楚地阅读所有的线条，在粉红色的三角形中，我可以阅读4：2：2和4：4：4。
4：2：2浅粉色，4：4：4浅粉色。
我试图用我的手机拍照，但手机没有屏幕正义。

Hi Peter.
I can have downloadad the picture and have display'ed it fullscreen i Ristretto (the Xubuntu Paint alternative).
I can clearly read all the lines and in the pink triangle i can read both 4:2:2 and 4:4:4.
4:2:2 in a lighter pink and 4:4:4 in a darker pink.
I have tried to take a photo with my mobile but the mobile doesn't do the screen justice.

嗨Jens，
您的图像被拉伸到全屏。
关键部分是像素到像素或100％渲染图像。
由于图像是817x720，因此它只占据3840x2160屏幕的一小部分（垂直1/3）。
参见附4：4：4,4：2：2和4：2：0的照片作为参考
最好，
彼得

以下为原文

Hi Jens,

Your image is stretched to the full screen. The critical part is to render the image pixel-to-pixel, or at 100%. Since the image is 817x720 it will occupy only a small of the 3840x2160 screen (1/3 vertically). See attached photos of 4:4:4, 4:2:2 and 4:2:0 for reference

Best,
Peter
