I am not from Intel and I don't really know that TV or Ubuntu. But a few things you might want to know. First thing to know is that you need to press a key such as F2 (not F10) to enter the BIOS setup (where you could disable network boot). That TV seems to be 1366x768, and the picture you show of text makes me think that you might need to look for some setting in the TV's setup menus to make it top trying overscan. Overscan was common in old TVs to avoid displaying the very edge of TV program, but for computers you want to display every pixel of the input, including the edges. Sorry I cannot easily access your TVs manual to know exactly what it might be called and in what setup menu. When you say "HDMI line" we assume you mean something like a direct HDMI input to the back of the TV; if you are instead plugging to something like audio-visual receiver or some converter box, those sometimes cause difficulty with NUC display (recent NUC BIOS seems to be trying to detect features of your display and then try to adjust its display, rather than just outputting in some PC standard such as VGA). Regarding Ubuntu, it might help others if you give more detail such as the version (I think some old versions might not support 1366x768) and is there some indication of what is happening before you get blank screen (does it display text for some amount of time but then become blank at the time you might expect some nice "graphic" screen). Consider adding any other info such as can you try a different monitor, does that USB stick boot on any other PC, does some other PC work with that monitor, etc.
Thanks for the reply
I actually tried pressing F2 as well (i tried all the F's and more)
Regarding the TV - I managed to turn off the scanner option and i see all the screen now (thanks ) but the rest is same
The HDMI is connected directly to the TV
The Ubuntu version i am trying to install is 14.04.2
When i plug the USB stick and turn the NUC on the blank screen is like that from the beginning, no text or anything.
more info (now that i see all the screen):
when i try to boot without the USB stick unplug the USB stick i can see the DHCP line running and then i see this
Intel(R) Boot Agent GE v1.5.53
CLIENT MAC ADDR: XXXXXXX GUID: XXXXXXXX
PXE-E53: No boot filename received
PXE-M0F: Exiting Intel Boot Agent.
Reboot and select proper boot device
or Insert boot media in selected Boot device and press a key
I will try the options you mentioned (other monitor and use USB stick on other PC)
Connected the NUC to another Monitor from the Mini display port outlet to DVI (using connector) and it worked ok
According to the store they also tested the same with HDMI and was ok
Also - Pen Drive of Ubuntu worked ok and we could enter BIOS
so it must be the TV i am using
Panasonic LCD TH-L32x50m
Also tried the other TV Panasonic Viera (Plasma )
