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.

Sadly there are currently no presets for these 2 resolutions for the framebuffer related cores (presets are found in qsys view menu), as I havent had use of these resolutions myself (in newer time). And I also have no (qsys) formula other than intuitive guess work..... Last there is the Devicetree entry this is the current one: https://github.com/the-snowwhite/soc-image-buildscripts/blob/master/SD-Image-Gen/patches/4.9.76-ltsi-rt/current/0012-Added-DE-10-Nano-with-uio-with-without-framebuffer-1.patch#L291 This entry: vip@0x100031000 { compatible = "altr,vip-frame-reader-1.0", "ALTR,vip-frame-reader-9.1"; reg = <0x00000001 0x00031000 0x00000080>; max-width = <1024>; max-height = <768>; bits-per-color = <0x8>; colors-per-beat = <0x4>; beats-per-pixel = <0x1>; mem-word-width = <0x80>; }; On Friday, 9 August 2019 03:55:13 UTC+2, justin White wrote: > > > > On Tuesday, August 6, 2019 at 1:07:38 PM UTC-4, Michael Brown wrote: >> >> Not very easy from my cell phone here however: >> In qsys there are 2 instances where you set up the timings for the screen >> monitor.
