Downloaded latest Jessie image for Cubietruck. Loaded to the sd card using instruction on site. When i power CT on, looks like it start booting, all leds are flashing as on normal boot, but screen is black.

Please advise what to check, how to debug.

Card seems ok, because i can boot other images.

You have 4k monitor?

i have hd ready tv, no monitor available at home

There are some problems with screen detection but so far this was noted on 4k / UHD monitors due too high / unsupported screen size. Whatever with HD and below should work. Please provide a log with armbianmonitor -u

 

You will need to connect via SSH or serial console.

i've seen in doc, that dhcp used by default. looks like i need configure dhcp on my laptop. is it right? or it has def.ip?

DHCP is mandatory and this is usually on your router on which you need to connect the board via Ethernet, at least first time, than you can configure for wireless connection for example. 

Thank you, i'll try
