三屏显示时HDMI不是设置为1920x1080吗？怎么变成240x320?

基于imx6q的3.14.28的BSP，实现LVDS+LVDS+HDMI三屏显示

refer to the IPU of imx6q in the Reference Manual, I don't think IPU can support HDMI 1080P@60 in your case,  for more detailed information, pls refer to the Reference Manual,

• Displays
• Five interfaces available. Total raw pixel rate of all interfaces is up to 532
Mpixels/sec, 24 bpp (266 Mpixels/sec per each IPU). Up to four interfaces may
be active at once.
• Two Parallel 24-bit display ports - up to 220 Mpixels/sec each (e.g. WUXGA+
@ 60Hz), or dual HD1080 + WXGA @ 60Hz.
• LVDS serial ports: One port up to 165 Mpixels/sec or Two ports up to 85
MP/sec (e.g. WUXGA+ @ 60Hz) each
• HDMI 1.4 port
• MIPI/DSI, 2 lanes @ 1 Gbps

是从否支持1024的双LVDS屏+HDMI1920x1080？

[joanxie]

"是从否支持1024的双LVDS屏+HDMI1920x1080？" what's difference from your orignal question? your orginal setting is dual lvds 1024 + HDMI 1080p, I don't think IPU can support your orginal settings
