non dmt/cea display setting

Thu Sep 06, 2012 6:28 pm

I've got a somewhat aging lcd tv that so far my pi recognises quite nicely, but the pi can't get some display settings that I can get on my PC. I ran /opt/vc/bin/tvservice and noticed the following two lines
HDMI:EDID found unknown detail timing format: 1360x768p hfp:56 hs:136 hbp:192 vfp:3 vs:5 vbp:17 pixel clock:69 MHz
HDMI:EDID found unknown detail timing format: 1360x768p hfp:72 hs:136 hbp:208 vfp:3 vs:5 vbp:22 pixel clock:84 MHz
which correspond to the best resolution on PC. Is there any way to make the pi use these even though they are neither dmt nor cea?

Dom (foundation guy) and his cohorts are working on non-standard mode support.

At the moment there is no way to truly have the Pi output 1360x768 at 69MHz or 84MHz as per your EDID. (or maybe I'm reading your EDID wrong, because these sound like very non-standard refresh rates)

You can try the 60Hz and 120Hz versions of 1360x768 if you want though

60Hz

Code: Select all

hdmi_group=2 
hdmi_mode=39
120Hz

Code: Select all

hdmi_group=2 
hdmi_mode=40
{sig} Setup: Original version Raspberry Pi (B, rev1, 256MB), Dell 2001FP monitor (1600x1200), 8GB Class 4 SD Card with Raspbian and XBMC, DD-WRT wireless bridge
