Installing a 17 inch HDR Full-HD touch panel into my home cockpit

I replaced the old display in my VF-1 inspired home cockpit with a touch panel. The previous display was salvaged from a laptop years ago and had a poor viewing angle. To improve this I experimented with an anti-glare foil that reduced the annoying reflections. However, the viewing angle remained poor, of course. To address this, I decided to go all in with a touch panel kit. The display model is N173HCE-E31, a 17.3" with a resolution of 1920x1080 and HDR support. The touch controller registers as a USB HID pointer/mouse by ILITEK and is basically a transparent touch sensing foil sitting on top of the display. The kit included a PCB that was advertised as VS-RTD2556HC-V2 by VSDISPLAY but came without any data sheet. It is not clear to me who really made it. Also this PCB runs **very hot** and it's voltage was not explicitly stated. I slapped a heat sink with a tiny fan on top on it and tried different configurations. It does work with just 5V at ~2A but I feel way more comfortable wi
