Horizontally mirror flipping

We are working in a 3D stereo Project with two monitors, so we need to mirror flipping horizontally one of them.

Our NVIDIA card is M5000, we have tried the Mosaic Utility driver and the Warp and Blend API to do it, but none of them Works.

Can you please explain us how to implement the mirror flipping with this card?

We can try with a RTX 3060 card. Is it posible with this card?, how can we implement it?
