So, i purchased a new NUC7i5BNH to serve as HTPC instead of a dying old PC (x10 bigger than NUC ) that could not handle newer content, and below are my first impressions.
1) The NUC looks very nice and sleek. I connected it to my LG plasma TV, via Yamaha RXV671 receiver and turned on.
2) First i wanted to enter BIOS screen, pressed F2 but all i was presented was a black/blank screen....tried few times for 15 minutes when switched to google...google was full of reports of the same issue, each suggested different solution...I tried to update BIOS to latest for couple of times using F7 method, but it did not work...every time i pointed it to BIOS file the system just restarted without updating and without any notice...I have owned many many PC's in my life and never observed something like that...anyway, after few more tries i was able to update the BIOS via Recovery BIOS procedure....however it did not solve blank BIOS screen issue
3) OK, so time to more google...i noticed people complained about the same issue when connected thru receiver, so i tried that next (although it wa not easy)...i disconnected my plasma TV from the receiver and connected it directly to the NUC and voila! The BIOS was there!......Now, i own several devices connected to the receiver(set-top box, XBOX 360, and one more PC), and all can show any output to the TV thru the receiver without any problem...so how come 2018 manufactured NUC (not some legacy device invented 10 years ago) cannot transmit its BIOS screen thru the receiver? Its definitely not resolution issue, after installing Windows 10 on it, i switched the resolution to 1024x768 inside Windows, and it was perfectly visible....somehow BIOS video output does not play well with receiver, and this is very sad - i dont want to go through PITA each time i want to update setting in BIOS....
4) Next i noticed the fan noise, so while in BIOS already i switched the Fan profile to Quiet, restarted but did not saw any difference in Fan noise! The Fan is audible close to the unit, even when NUC does nothing....i will try Fanless profile next, however i need again to disconnect the TV from receiver and connect it directly
5) In Windows 10, after installing all drivers (validated with Intell support tool) i still have some unknown device without driver...need to figure it out
6) I configured the NUC for HDMI CEC control....however this thing is unpredictable....when NUC turns on it turns on the TV but receiver remains in standby...when i turn NUC off, it switches off the receiver, but TV stays on! Moreover, the NUC waked up from sleep by itself at night and switched on the TV ...and thats how i found it in the morning..i hope my plasma TV did not get burned..i am going to turn off HDMI control feature until I understand how to operate it reliably...
All and all i got mixed feelings...i am a tech enthusiast, owned many PC's and streamer's and out of the box NUC experience is not that great and even a bit disappointing... It would be great if Intel representatives can relate to the issues i pointed out
Thank you for joining this Intel Community and providing your feedback. It is highly appreciated.
In order to address these issues correclty, I would like to gather some information about your setup. Please provide the following information since there is useful information we can discuss.
-Describe how you are connecting your Intel® NUC > AV Reeceiver > TV.
-Intel® System Support Utility report.
1.Download the Intel® System Support Utility and save the application to your system.
2.Open the application and click Scan to see system and device information. The Intel® System Support Utility defaults to the Summary View on the output screen following the scan. Click the menu where it says summary to change to Detailed View.
3.To save your scan, click Next and click Save. You can save the file to any accessible location on your computer.
4. Attach the report to this thread.
Thanks for responding.
My Setup is : NUC ---> Yamaha RXV 671 (over HDMI cable) ----> LG 60PK250 TV (over HDMI cable)
I will run the utility later today and upload its summary.
One more point i am disappointed about is that NUC advertised (modestly i might say..it does not appear on the box itself, only in specs) as having IR receiver built-in. When using NUC as HTPC this is pretty useful feature - being able to control it remotely. This was one of my buying points. However i now learn that the built-in IR receiver is not generic and will only work with MCE compatible remotes, so I cant use any of my existing remotes, including universal learning remote, since it does not happen to be MCE RC6 compatible! Now i need to buy MCE remote or some other remote with dongle and occupy another precious USB port....why guys couldn't you provide GENERIC UNIVERSAL IR receiver with drivers so any common remote could work?? Anyway, advertised specs should have been very clear about this and should have clearly state that only MCE compatible remote is supported!
See the attached file.
I also have additional issues, with NUC keeps waking my TV (it runs kodi, which is configured to put it into suspend mode after 10 minutes...i turn off TV and after 10 minutes NUC wakes the TV up, instead of going to sleep...). Also, after waking NUC from sleep, ther is a picture corruption (few blue lines, that disappear after few seconds) and kodi only shown on half of the screen...i have to exit it and reenter)....too many issues with this product...
So, small update...kodi shown on half screen after wake was kodi issue...i used latest v18 kodi betas and thats was the behavior...rolled back to kodi 17.6 and kodi is on full screen after wake....
other issues still exist - noise on hdmi after wake or after refresh rate change for a few seconds....
also sleep issues still persist...today morning NUC was awake again and turned on TV....in event viewer i see it "waked up source:unknown"...not very usufull...also i see BT driver error in events viewer after wake up:
"BTUSB , event id 18 , Windows cannot store Bluetooth authentication codes (link keys) on the local adapter. Bluetooth keyboards might not work in the system BIOS during startup."
the NUC wake issues very frustrating....
ok another update...i was able to resolve wake up issue...it was setting in the NIC driver "Wake on pattern match", once disabled, NUC stayed in standby...
so current issues are:
1) cant see BIOS thru receiver
2) noisy video output after resume from wake and when changing refresh rate - blue lines running on screen...this disappears after few seconds
3) sometimes after resume from wake TV goes blank for couple of seconds...i believe this is related to HDMI handshake...
Thank you for your response.
I am glad to hear that you were able to resolve some of the issues described before.
Because you are able to enter BIOS when connecting the Intel® NUC to your TV, I was wondering whether there is an input/output setting in your AV Receiver you can modify. Also, you can perform an HDMI® firmware update.
HDMI Firmware Update Tool
If you need instructions on how to perform this update, there is an updated file here:
Additionally, you can try installing the latest graphics driver update for Intel® Iris™ Plus Graphics 640. According to the report attached, you have this version: 220.127.116.1125
Thanks for your support.
I updated HDMI firmware from your link but it did not solve the issue...i did not updated VGA drivers yet but i guess they have nothing to do with this problem...anyway, I remembered that my TV got another HDMI input so i guess i can live with attaching to it directly if i need to use BIOS...speaking of which, i am trying to eliminate fan noise (BIOS shows fan spinning at ~3700 RPM, producing high pitch noise)...i tried different policies, like Quiet Custom and even Fanless and did not notice any difference....only choosing Fixed with due period of 30 (minimum) reduced the RPM to ~ 2600, and the fan as inaudible, but i am afraid this is not ideal solution as cpu will get hotter under load....any idea how to configure this thing so that it stays quiet (~2600 rpm with no load) ?
Thank you for your response.
Regarding the noisy fan, you can review the following thread, which contains additional recommendation about this issue.

Keep in mind that these are recommendations that worked for other users having the same issue. You can always select the Fan Control Mode desired in BIOS.
