I'm trying to switch Raspberry Pi to a new monitor, but monitor complains about not getting HDMI signal. The old monitor was attached via HDMI-DVI cable, while new monitor has HDMI-HDMI cable and then HDMI to Display Port adapter as monitor only has old VGA and DP input. Monitor is 24" Dell E2416H.
Pi boots OK and I can SSH to it.
I've tried playing with most of the parameters with the same effect, but most notably:
tried boosting HDMI signal with
config_hdmi_boostto 4 and to 7
tried booting without SD card to display test rainbow screen; no rainbow seen
hdmi_mode=1(VGA 60Hz) and monitor native
Both result in this mode:
pi@screenly ~ $ tvservice -s state 0x40002 [NTSC 4:3], 720x480 @ 60.00Hz, interlaced pi@screenly ~ $ tvservice -m CEA Group CEA has 0 modes: pi@screenly ~ $ tvservice -m DMT Group DMT has 0 modes:
hdmi_force_hotplug=1(in combination with
hdmi_mode=16) does indeed force HDMI...
...but still nothing on the screen:
pi@screenly ~ $ tvservice -s state 0x12001a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive pi@screenly ~ $ tvservice -m DMT Group DMT has 1 modes: mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive pi@screenly ~ $ tvservice -m CEA Group CEA has 2 modes: mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive (prefer) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
Can anyone offer some advice or ideas?
EDIT: Solved by using HDMI to VGA adapter. However, I'd still like to know why DisplayPort doesn't work... is there anyone who successfully runs Pi on DisplayPort?
