The reported problem is about HP laptops with i915 driver (no matter chip chip is) and several monitors with resolutions more than the laptop panel. The LVDS provides only the native resolution (either 1366x768 or 1600x900) and a few other VESA ones (1024x768, 800x600 and 640x480). Meanwhile, the monitor EDID doesn't provide such laptop-native resolutions. Thus, in clone mode, the only possible resolution is 1024x768 or lower. That's the whole problem. It's too low and doesn't match with 16:9 although both laptop and monitor panels are 16:9. HP wants the clone mode of the laptop-native resolution and/or a higher resolution with the right aspect ratio like 1280x720. Neither work as of now unless you add the extra mode manually. > Can you provide some EDIDs? OK, here we go. Outputs of "xrandr --verbose" and EDID data from two monitors. thanks, Takashi
