There is an issue with database entries, it seems to be empty.

I2cDevice 22785: Some("ACR") Some("VG280K")
Database {
    entries: {},
}
I2cDevice 22786: Some("ACR") Some("VG270 S")
Database {
    entries: {},
}

and the code I ran:

    use ddc_hi::{Ddc, Display};

    for mut display in Display::enumerate() {
        display.update_capabilities().unwrap();
        println!(
            "{:?} {}: {:?} {:?}",
            display.info.backend,
            display.info.id,
            display.info.manufacturer_id,
            display.info.model_name
        );
        println!("{:#?}", display.info.mccs_database);
    }

System Specs: rust 1.68 arch linux nvidia rtx 3050 8gb gpu both monitors are connected via the gpu.

Hm... is this 0.4.1? Probably try running it with RUST_LOG=trace (assuming env-logger is available) for some more info - or try running RUST_LOG=trace ddcset capabilities and/or detect for comparison

Same issue, everything is empty except for the backend (winapi) and the ID which is Generic PnP Monitor. Running Windows 11 Pro 22H2, OS build 22621.1702.

Besides the above suggestion, you can also try:

println!("{:?}", display.handle.capabilities_string().unwrap()); and share here to see if the caps string is invalid in some way
ddc-hi v0.5.x branch (or building ddcset main branch), which uses the newer mccs parser
