Hi, i do this few weeks ago for LVDS display...
What i did in u-boot configuration:
CONFIG_VIDEO_SUNXI=y
# CONFIG_VIDEO_HDMI is not set
# CONFIG_VIDEO_VGA is not set
# CONFIG_VIDEO_COMPOSITE is not set
CONFIG_VIDEO_LCD_MODE="x:1024,y:600,depth:24,pclk_khz:51000,le:319,ri:4,up:34,lo:2,hs:1,vs:1,sync:3,vmode:0"
CONFIG_VIDEO_LCD_DCLK_PHASE=1
CONFIG_VIDEO_LCD_POWER="PH9"
CONFIG_VIDEO_LCD_RESET=""
CONFIG_VIDEO_LCD_BL_EN="PH8"
CONFIG_VIDEO_LCD_BL_PWM=""
# CONFIG_VIDEO_LCD_BL_PWM_ACTIVE_LOW is not set
# CONFIG_VIDEO_LCD_PANEL_I2C is not set
CONFIG_VIDEO_LCD_IF_LVDS=y
# CONFIG_VIDEO_LCD_PANEL_PARALLEL is not set
CONFIG_VIDEO_LCD_PANEL_LVDS=y
You should enable HDMI instead of my LVDS display and set correct
times...

Hello.
Need help to enable HDMI output on u-boot load.
At current time HDMI output work only after linux kernel is
loaded. At u-boot time HDMI output is blank (no signal on monitor)
.I try some option like
setenv video-mode=sunxi:1024x768-24@60,monitor=dvi,hpd=0,edid=1
setenv video-mode=sunxi:1024x768-24@60,monitor=dvi,hpd=1,edid=1
setenv video-mode=sunxi:1024x768-24@60,monitor=dvi,hpd=0,edid=0
setenv video-mode=sunxi:1024x768-24@60,monitor=hdmi,hpd=0,edid=1
setenv video-mode=sunxi:1024x768-24@60,monitor=hdmi,hpd=1,edid=1
setenv video-mode=sunxi:1024x768-24@60,monitor=hdmi,hpd=0,edid=0
and
setenv hdmi.audio=EDID:0 disp.screen0_output_mode=1024x768p60
setenv hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1024x768p60
Full output of U-BOOT load
