The backlight is LED, so it's not likely to ever wear out, as it were.

I've replaced a a large number of them in flat screen televisions. LED's don't last as long as it is commonly believed.

I don't want to waste extra energy on the screen,

Understood.

If you want to test memory allocation/use on Linux, use Valgrind.

OK i got some collimator lens and a diode mount that sits diodes in a place where I can attach a little heat exchanger to them do temperature control for experiments (brass or copper)

the prices are not people friendly, but getting the emitter section and safety right, lets me allow for messing around with the subsequent optics, hopefully at a much lower cost. (adjust prisms, mirrors, screens, etc), hopefully maybe with some scavanged and DIY stuff. I have a bad feeling about the cheap chinese mounts, as simple as it seems.

Building your own laser diode mount seems akin to building your own power supply chassis, which is a bit much for beginners. I hope the thermal contact surfaces will be good and that it mounts well and is more stable then something I can put together myself, that I will not need to fight with a tapered, oval or otherwise messed up bore for mounting diodes.

Is there any reason or evidence to think that a screen saver is even required for this kind of screen?

The backlight is LED, so it's not likely to ever wear out, as it were.

I don't want to waste extra energy on the screen, especially when the screen is supposed to be off. Whether or not the screen itself needs it, I dunno.

Walked up to him and he was sleeping - no movement. I said "Maxim it's time to get up". His tail twitched a few times. I waited and he remained motionless. Then I said the same thing again. His tail twitched a few times again. He must be aware of my voice but remains asleep - or so it looks like.

Oscilloscopes are for displaying signal waveforms, not creating them.

There's an option in the config settings for better accuracy OR cleaner signal. The glitches exist either way.

While I no longer sell scopes, this is a page from my site that will give you some hints on what to look for.  It is targeted toward watchmaking, but the details apply to all scope buyers.
