Hello,
I have a problem with an old TV that I want to use as an external monitor.
I read in the manual that the highest resolution possible using HDMI is 1920x1080i. This worked with my raspi also.
The maximum resolution possible with vga would be 1440x900p.
Unfortunately the EDID only seem to obtain the possible resolution using vga, although i am using HDMI (mainly because my grapphics card has no vga port).
So if I run xrandr the highest possible resolution is 1440x900p, which is not working and I don’t know how to add the mode for 1920x1080i.
Right now the monitor runs at 720p, which is not looking as good as it could.
I did not find any possibility to use interlaced signals. Is this no longer supported?
Please tell me if you need any information about my system. I have no idea what is important here. My graphicscard is a rx 590.
This is what I see after running xrandr:
