Cheapest Graphic Card Please guide me ?


I ordered ryzen 3600 but know i need graphic card
But my budget is very limited because order something
But i don’t want play game , and only work with adobe Photoshop and for video editing software for video rendering

So someone told me , buy only display adaptor because video editing no need powerful graphic card

and i don’t want buy used graphic card because of risk of quality

Now only tell me is there any cheap brand new graphic card or any display port about maximum $50 ?

and what is their mean about display port ?

thank you Number
