I want to run Memtest86+ overnight, but I need to turn my monitor off for that period. Unfortunately, every time I turn the monitor off while Memtest is running, when I turn it back on, it's getting no video signal, so I cannot see any test results. Manual switching the input source on the monitor does not help - when I switch back to my input, the monitor just says again, that there's no signal.
Memtest itself is not frozen, because it reacts to my pressing Esc, and shuts down the computer (pressing any other keys does not show the screen, so I don't know if they are actually working; but I suppose they are, I just cannot see the reaction). Also, I tried turning the monitor off after about a minute of the running test, and turn it back on a few seconds later, and it still got no video signal. And if I keep it on, I can run it for at least an hour without any issue or any memory errors, so it's not caused by the long run.
I'm using the latest available version of Memtest86+, 5.31b, but the same happened with 5.01. Is there any possible workaround, which would let me see the test results? I walked through the settings dialog, but failed to find anything of use.
In case that's relevant, my GPU is nVidia 1660Ti, monitor is NEC PA241W, connected via DisplayPort.
