bad video driver.
PC too old vast old PC has no edid pin.
I can not find a good spec on i-menu, how old of GPU cards work
edid or DDC2 card both?
ESA DDC2-B/CI<<< the card needs to do this level hardware
here is what DDC2 is (wiki facts)
The combination of EDID and I²C is called
Display Data Channel Version 2 (
DDC2 ). The "
2 " indicates that DDC2 is different from
VESA's original DDC (they use a different serial format).
i'd say off hand I-menu talks down DDC2 line.
and the card you run has no DDC2 level support it fails
or the video card or chip GPU has a wrong DRIVER loaded or non at all.
that is the best I can do lacking full spec on i-menu
here is my Nvidia driver doing DDC2 right now , remote
gtx1650(game grade not cheap)
if not gaming and not wanting have deep pockets for 1 VGA CARD
here is a best choices for cheap card, and DDC2.present
VGA only, pins 12 and 15 , DDC2 grade.
the huge problem is VGA is not sold now new. so only old cards have vga (or buy and adapter that is VGA to HDMI and does DDR2.
is bi-directional level (DDC2)
nVidia 950 with vga to dvi plug adapter in the box. $10 used ALL
newer cards even no VGA have DDC2 or edid or both and with an adpator, there is edid pass though even VGA to DVI.
not one video card maker i can find lists cards they made with edid.
or full DDC2B (both)
the best deal IMO is DVI, with the passive free VGA adapter.
I know how to scan the GPU card/chip to learn if edid is there.
full edid both directions
I do not know all cards that can do cheap, my guess is the 950
sniffing App. ddc2 edid v1.3 up is best.

FIND a GPU card with DVI and has Edid v1.2 or 1.3
