I have a small monitor I would like to use beside my big monitor. The monitor is DVI and my 3080 only has data port and HDMI. So I bought this adapter https://www.amazon.com/gp/product/B01GPMRXL0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. Before I use it I thought it wise to get an opinion. Is this adapter legit? or is there more to a Data Port X DVI conversion then pinouts? I don't want to fry the GPU just because I wanted an additional little screen for no good reason other than it is there.
