Screen not detected on NUC8i5BEK2

[SDaro1]

I can't have any screen detection on the HDMI port with my freshly bought NUC8BEK. The screen is working perfectly with another computer.

As I don't have any visual, it's impossible to access even the BIOS.

Hi @SDaro1​,

Have you tried to connect your NUC to another screen (e. g. a TV)?

Have you tried to connect your NUC to the screen with another HDMI-Cable?

What is the screen model you use?

[SDaro1]

Hi,

thanks for your answer.

I've tried to connect the screen with few other HDMI cables, without success.

Unfortunatly I don't have another HDMI screen to test with but the screen is definitly working (and I've bought the NUC specially for it).

The screen is a ASUS VE278Q https://www.asus.com/us/Monitors/VE278Q/

1. Does it has RAM memory and SSD storage drive installed?
2. If you have installed RAM memory (since you write that it is new NUC), please try to test it in minimal hardware configuration:
3. Open the bottom cover (disconnect the Power Cord first).
4. Remove the SSD drive and one of the RAM modules (if you have two modules installed. Work with one memory module at time - in upper and lower slot.
5. Remove the Yellow Security Jumper. See page 41-42 in the Technical Product Specification https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i3BE_NUC8i5BE_NUC8i7BE_TechProdSpec.pdf
6. Reconnect the Power Adapter and power ON the NUC. After about 30 seconds you should see Configuration Menu.

The RAM is indeed properly installed (G.Skill RipJaws Series SO-DIMM 16 Go DDR4 2666 )

I've removed the security jumper and the SSD disk as you suggest, but it doesn't work, the screen is still not detected, even after few minutes.

I've tried two HDMI cables to be sure.

1. Do you have two SO-DIMM modules? Test with only one module at time, first in lower slot then in the upper slot.
2. If you have only one SO-DIMM module, borrow an other one and try (may be from laptop)?
3. What is the Power LED indication? There is one?
4. Some time disconnecting the Power Adapter for few hours helps.
5. In other cases disconnecting the CMOS battery for 15 minutes helps. However in order to access the CMOS battery connector you need to remove the board. I can give you instructions how to do this, but better is to return this NUC to place you bought it for replacing.

Thanks for our help. I have only one SO-DIMM module, I've tried with upper and lower slot without success but I don't have another (or I need to buy one).

The Power LED indication is on and blue. The NUC seems to power on.

I've read that there is other peoples experiencing problems with the HDMI port, but I can't be sure that the problem have really the same origin.

So I've ordered two cables USBC -> HDMI and USBC-> display port.

Maybe it'll give me a practical solution, and help me know if it's the HDMI port or the NUC himself.

If not, the better would be probably to return for replacing before acting deeply (but how boring!).

1. It is good idea to try the DP output. However if it doesn't work, it will not prove that the problem is in NUC, since the problem may be cause by failed or incompatible SO-DIMM.
2. Only 2400MHz SO-DIMM modules where validated by Intel for your NUC http://compatibleproducts.intel.com/ProductDetails?activeModule=Intel%C2%AE%20NUC# . I don't know what is the P/N of your memory, but you wrote it is 2666MHz module? That is why important is to check with other module.

Hi,

is that already fixed?

I think that NUC8ix running alternative mode in HDMI port. if so, It's happening a initialize fault.

I've tested the display port without any result, so the nuc has been returned.

oh I see, thank you for your reply.

I might return the PC in 30 days to Amazon too.
