"Out of Range" error on native resolution?

    I'm having a bit of trouble with one of my screens. The monitor is a "Planar PCL2780MW", basically a no-brand 27" 1440p screen.

    The monitor has inputs for DP, HDMI, DVI, and VGA, I have not tried DVI or VGA. On HDMI it will not expose the native resolution to windows, but will expose it over DisplayPort. I'm currently using it on HDMI, which I did for several years without issue by setting a "custom" resolution(really the monitor's native) in nVidia control panel.

    After doing DP with few(er) problems for about a year, I just switched back to HDMI, and now the old custom res trick is not working right. I get weird lines through the screen and the monitor displays an "Out of Range" error every time I start it up(this is, again, on the actual native resolution).

    Has anyone encountered this sort of thing before? I don't have a long enough DP cable now, but I'm willing to try VGA or DVI if it'll work.

    At first I was thinking it may have something to do with differing supported refresh rates, but checking the specsheet I see that it officially doesn't support more than 1080p on HDMI. Switching to a DVI cable would probably be the easiest and fastest fix.

    FOR PC: VGA Support up to 2048 x 1152, HDMI Support up to 1920 x 1080,DVI-
    D/ DP support up to 2560 x 1440 (non-interlaced);

    I think early versions of HDMI only supported lower resolutions, which may be what you are running into here. HDMI and DVI use the same electrical signaling, so that may have been why you were previously able to trick it into accepting the signal. No idea why your previous workaround stopped working.

    If you're on an NVidia card and using the control panel to select resolution, make sure to scroll way down. On this LG C2, I get a whole bunch of HDTV formats first, all of which cap at 60Hz. Only much later are the PC resolutions exposed, which go to the panel's full 120Hz.

    This may be unique to HDMI 2.1. Your older HDMI version may have nothing of the sort.
