The DC has nothing to do with monitors because monitors are just
different coordinates on the same (virtual) screen. (Obviously
since you can drag the window between monitors, even such that
it's partially on two monitors at the same time.)

To get the the size of the monitor where your window is (mostly)
on you can use:

    HMONITOR hMon;
    RECT s;

    hmon = MonitorFromWindow(your_hwnd, MONITOR_DEFAULTTONEAREST);
    mi.cbSize = sizeof(mi);
    if (GetMonitorInfoA(hMon, &mi)) {
        s = mi.rcMonitor;  // entire screen, or
        s = mi.rcWork; // without taskbar
