NUC6CAYH, Samsung UE28H4000AW, No Input Detected.

Hi there,

Unfortunately the combination of my NUC and tv doesn't work properly. HDMI 2.0 Firmware Update tool 1.66 installed.

Following are the details.

Description

Provide a detailed description of the issue

Turning on the tv, than the NUC, results in the tv not seeing any signal from the NUC connected to either ports HDMI 1 or HDMI 2 on the tv, mentioning "No input detected". The tv does flicker/switch once, noticing the NUC is starting. Neither the boot splash screen, nor the OS desktop is seen. The NUC boots successfully as i can connect to it over the network. Rebooting the NUC up to 10 times eventually results in showing the boot splash screen and the OS desktop. The VGA connection plugged into another display does not seem to have any problems. Re-plugging the HDMI cable has no effect, tv flickers/switches once but eventually will show "No Input detected". No connection/display issues at all with a satellite set top box connected to the same tv.

Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")<p>

Seems i messed up the form, sorry for that. Will provide a new one if needed.

I'll repeat the problem description.

Samsung UE28H4000AW television rarely sees input from a NUC6CAYH. Needing up to 10 reboots of the NUC to see an input signal.

Tried with 3 different so called "high speed" HDMI cables, on both HDMI inputs on the tv. Selecting the correct input on the tv does not fix the issue.

Anything else i can try to solve this?

Jeroen

Hello Jeroen_,

Thank you for joining the Intel® NUC community. My apologies for the inconvenience.

Have you tested a different TV/monitor with the Intel® NUC?

I recommend testing the following driver version: https://downloadcenter.intel.com/download/26772/Graphics-Intel-Graphics-Driver-for-Windows-15-45- Download Intel® Graphics Driver for Windows* [15.45]

Hi Amy,

Thanks for the reply.

I've tried with the driver you linked. No difference at all unfortunately.

Also like you mentioned I've tried on another tv, a Samsung UE40EH5000wxxn. Unfortunately with the same result, "No Input Detected". Selecting the correct source input in the tv menu does not change the result.

Both tv's have no issues with satellite boxes or other computers connected to their HDMI inputs.

To me the issue seems to exist before the operating system loads. Most of the times not even the bios splash screen shows when starting the NUC. (bios splash screen: the text Intel® NUC in the middle of the screen, F2 to enter Setup and so on in the lower right.)

Regards,

Jeroen.

Thanks Jeroen.

I would like to know if the cable you have tested are HDMI 2.0. Is there any chance to test a HDMI 2.0 cable version?

Hi Amy,

On both tv's i've tested with 3 cables.

1 generic/no brand "High speed HDMI cable"

1 generic/no brand "High speed HDMI cable with Ethernet"

1 Monster branded "Gold Advanced High Speed HDMI Cable with Ethernet", part number 140737-00.

With all 3 cables the same problem occurs.

Jeroen

Thanks Jeroen.

 

 

 

I was unable to confirm if these are 2.0 category. Can you confirm if any of those are HDMI 2.0 category?

Hi Amy,

I think all 3 cables are HDMI 2.0 compatible, based on this information from the HDMI Licensing Administrator.

https://www.hdmi.org/learningcenter/kb.aspx?c=17# 144 https://www.hdmi.org/learningcenter/kb.aspx?c=17# 144

https://www.hdmi.org/learningcenter/kb.aspx?c=17# 123 https://www.hdmi.org/learningcenter/kb.aspx?c=17# 123

The Monster branded cable mentions a guarantee of ">18.0 Gbps bandwidth".

Apparently most of my friends and family have Samsung televisions of approximately the same age and series. Today i will try testing on another brand of television.

Regards,

Jeroen.

Hi Ami,

After testing the last 2 tv's i went back to the shop where i bought the NUC, they've tested as well and agreed that the unit was faulty. They exchanged it for a new one which seems to work like it should. The issue is resolved.

Thank you very much for taking the time to help.

Regards,

Jeroen
