Hi so forgive the noob questions but i picked up a KTX CAE565SG and it has soldered in vga and power connectors but the power terminates in a male IEC as shown:
while i do have spare female iec to wall cables i figured id google around a bit first and found this quora thread and a comment from Richard says:
"One of the monitors, I believe the color one, required the video signal from the computer to generate that signal. In fact the CPU clock frequency was specifically chosen in the original PC to generate as a sub-harmonic the horizontal frequency. In any event, if you plugged in the color monitor without a functioning computer video signal, its power supply literally burned itself out. So the answer was to make sure the monitor draw its AC power from a switched socket on the computer itself so that it would always have the proper video signal."
I'm assuming this tube is 15khz so my hdmi/displayport to vga adapters likely wouldn't output such a signal?
i picked up a DisplayPort to HDMI VGA Adapter DP2VGAHD20 as it's a commonly recommended by reddit as I've been testing numerous CRTs lately although i fear I've got one of the cheapened down variants, a few crts ive used will randomly cut video on and off however with a no named generic random hdmi to vga adapter works just fine 🤣.
the startech does have a legup where it usually detects the actual monitors name and only lists its max supported res/refresh rates vs the generic where you can push a lot of unsupported modes.
to add to this apprently this specific model CRT was recalled in Australia!
so that info plus the comment saying certain ibm crts burned out without a video signal and I'm just wondering what's the best way to power this up without starting a fire haha.
would powering this via wall socket instead of the 2port psus fry it without a video signal? and is it possible to output a 15khz signal from a modern pc?
