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

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 = <0x0001 0x00031000 0x0080>;
max-width = <1024>;
max-height = <768>;
bits-per-color = <0x8>;
colors-per-beat = <0x4>;
beats-per-pixel = <0x1>;
mem-word-width = <0x80>;
};

Well It would be nice with a hal rt component for calculating temperature
readings based on ntc probes instead of the python user component
hal_temp_atlas I derived from the hal_temp_bbb :-)
