I am looking for a decent quality right angle HDMI connector for the touch-screen. Has anyone found any that work? I just received one from Amazon that was too loose in the socket. I found a right angle USB but the HDMI was a no-go. – I also noticed that the display will work without using the power supply. I can only assume that it is getting the power from the HDMI or USB. I realize this will be a little more current draw on the controller but is this a problem? If I could get away with one less cable that would be fantastic. @OnefinityCNC ---

It won’t stay powered on reliably unless you attach the power USB-C to a wall wart. ---

Thanks! I appreciate it! I am looking for a cable that angles down rather than back but maybe this MFG makes one that will work. Regarding running without a PS, I only left mine on for 5 or 10 minutes but it didn’t seem to blink. I found a 3.5mm right angle power extension cable but I guess the inside diameter wasn’t right. It would lose power when wiggled. If I could find the right connector I would just cut the cable and solder in a replacement. I might take the screen apart and see if I can get a caliper on that inner pin. The cables that came with the screen are nice… but frankly unmanageable. I had planned on not even using the supplied monitor and just run through my computer but I decided to go ahead and hook it up. Then I lost hours of my life trying to find workable cables. Such has been my life. Getting close to putting this silly thing in the closet like my original plan. ---

> [@Ziggy](#): > > Regarding running without a PS, I only left mine on for 5 or 10 minutes but it didn’t seem to blink Was that while the 1F was cutting a project? The controller doesn’t use much power when idling but the power need goes way up when the RPi is running a program. > [@Ziggy](#): > > The cables that came with the screen are nice… but frankly unmanageable. Yeah, they’re hanging out there defying gravity with the weight of the cable levering the connectors. I switched them to angled connectors so the moment of inertia was minimized. It’s also why I didn’t rotate the screen - where they are, the way I built my table they aren’t in jeopardy of me knocking into them as I move around the table. I set up a laptop stand so I can use that too, but the controller & monitor let me put the laptop back inside while a project runs. I like the versatility. ---

That was only sitting idle. I will take your advice and find a better connector for the PS. It’s funny, I don’t see many differences in the pin sizes for that connector. Maybe I just received a cheap extension cable. [Right angle DC extension cables.](https://www.amazon.com/dp/B0851B8K6W?tag=benmyers-20)
