Subodh, I see you asking lots of questions that don't get answered on the DirectFB mailing list. Please take a moment and read through http://www.catb.org/esr/faqs/smart-questions.html, it will give a lot of pointers on how to ask better questions.
Specifically, your questions lack some important information: 1) what development board are you using? You mention the imx6Q, but there's a lot of different boards for that, and they may be wired up differently. 2) what Linux distribution are you using? You mention the DFB version number, but not the rest of the system config. It looks like you're using something based on Yocto based on the log output, but let us know if you built it yourself or got it as part of a board support package. 2) what have you done to try to solve the problem? Just giving an error dump is a very open-ended thing. State things like "I looked for a configuration to adjust the resolution" or "I tried using an alternative output". For this specific question, I'd first see if the monitor supports the mode you're using. Try to make a laptop connect in that same mode to verify that it's working. If that doesn't work, try making the DFB config use a mode that's more common on HDMI, like 1280x720x60. Also know that it's very likely no one else on this list has your exact setup. dfb-users hasn't been very active recently, so you might be on your own.
