	* ~~Nothing has~~ to ~~be done~~		* HDMI/DVI output shares video signals with LCD. As by default LCD interface is 18bits wide and HDMI requires 24bits, screen will appear with bad colours. To correct that you have to modify the following files: ''buildroot/output/build/linux-2.6.38.8/arch/arm/mach-mx5/apf51dev-baseboard.c'' and change line 205:
			<source lang=c>
			static struct ipuv3_fb_platform_data apf51dev_fb0_data = {
			- .interface_pix_fmt = IPU_PIX_FMT_RGB666,
			+ .interface_pix_fmt = IPU_PIX_FMT_RG24,
			.modes = apf51dev_modes,
			.num_modes = ARRAY_SIZE(apf51dev_modes),
			.display = 0,
			};
			</source>
			* then recompile Linux image and reflash it on your board:
			<pre class="host">
			$ make linux
			</pre>
