The socket emits the bytesWritten() signal every time a datagram is written to the network. If you just want to send datagrams, you don't need to call bind(). The readyRead() signal is emitted whenever datagrams arrive. In that case, hasPendingDatagrams() returns true.
Signals and slots are loosely coupled: a class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.

I can't use the 1080p resolution because my monitor doesn't support it, thus the setting to 720p.So I suspect this isn't working either because I need a 1080p monitor or a full x4 pcie slot.

(A local variable, passed to emit() may well be deleted by the time the slot method is called...).. The code added to PythonQtSignalTarget::call() needs to be removed, and instead, line 114 of PythonQtSlot.cpp replaced with: qwt / Segmentation Fault - SourceForge Segmentation Fault.
