Where can I get some 1080p Retroarch flat borders?

Where can I get some 1080p flat borders (the ones without round edges)  for Retroarch?

I see a lot here:

 

https://github.com/libretro/overlay-borders/tree/master/16x9 Collections/Nosh01 1440 Plain

But these ones are 2560×1440 and cause some systems to still have some black on the sides, as seen on the attached picture.

Some NES games and emulators have a black border no matter what. Make sure your emulator's overscan and aspect ratio settings are properly set.

I use and recommend Zaazu's Bezels, their black and grey color scheme make them not too intrusive, focusing the screen on the game, not the border.

You might want to look at The Bezel Project for Windows as well. I'm not a fan of bezels in general, but I did try these out on one of my systems to see how they looked, and was overall impressed by their work.

ETA Prime did a good video explaining how it works, etc.  Have a look at his video before downloading, as it might not be what you're looking for:

EDIT: Looking back at your question, this might not be ideally what you're looking for.  These are not flat borders, they do have a CRT curve in the overlay.  However, still might be worth a look.  If you want to try them out, backup your retroarch folder and then install.. if you don't like them, just restore from your backup.
