Tried this one for Switch and seemed to work fine for its price. I'm still new to this myself and don't know all the ins and outs. Ended up buying a $70 one to try 1440p resolution, realized I think I need to upgrade my longer HDMI cables.

For reference, this is the card I'm closest to buying, though I do have some doubts so I'm uncertain.

It’s just a $30 one from Amazon https://www.amazon.com/gp/aw/d/B08SBTK4QH?psc=1&ref=ppx_pop_mob_b_asin_title

you talked earlier about getting a capture card. i dont think the price for this one is that bad and reviews seem good. you think this would work?
