Been away from this project for a short bit but I had a pretty good use come up for it recently. Main thing I'm having a problem with is the FB resolution that was configured, 1024x768 is a dead resolution. Only old monitors natively support it and nothing with HDMI does. Larger HDMI monitors can handle it but nothing in the 7-9" range can display it through HDMI. That's unfortunate because the main reason for FB use with this thing is for an HMI all in one type device. Is there any chance more monitor resolutions can be supported?
I asked this before and MB responded, but unfortunately this is over my head > OK back to being able to be online with my workstation: > I have allways had a fight setting up proper display resolutions on the > altera soc's however I can give you some key notes: > In qsys there are 3 cores to consider: > For display timing settings: > alt_vip_vfr_hdmi (framereader) > > alt_vip_itc_0 (Clocked video output) > > The display core clock itself: > pll_lcd --> lcd_clk > > > 1600x900 would allow me to test it out on my mill and I might have a use >> for 800x480.
