Thank you. Changing /etc/xdg/weston/weston-genivi.ini is also something I tried. In the logs of weston, I can see that LVDS1 gets disabled (when I set mode=off) and that VGA1 is enabled (looks fine). The resolution and timings correspond to what the display detects, but the screen remains black.
In the meanwhile, I found a VTC1010 (= the reference hardware). I tried it but get exactly the same result as on my VTC7110 : black screen (with tizen-ivi Modello and tizen-ivi Core). The log of weston only mentions VGA1 (with the right resolution : [11:06:55.154] Output VGA1, (connector 9, crtc 3) mode 1024x768@75.0, preferred, current ). As this is the reference board, I wondered if there was something wrong with my image. So, I downloaded the sample image "tizen-ivi-core-image-dev-valleyisland-32.ext3" and tried it on my VTC1010. The result : a black screen. What could be wrong ?

One potential problem can be that weston tries to render to the wrong (non-existing) display. To eliminate this as a source of problems it is best to turn that explicitly off in the weston config file. Have you tried adding [output] name=LVDS1 (check the correct name for this from the weston logs) mode=off /etc/xdg/weston/weston-genivi-modello.ini, or /etc/xdg/weston/weston.ini ?
