Any HDMI switcher will work . Get a DVItoHDMI cable and run it from your monitor to the HDMI switcher and then use a standard HDMI cable from your PS 4 Pro to the switcher and another DVItoHDMI from the GPU to the switcher . <| sep |> As someone else observed , you ' re in Germany , where most couples will have done lots and lots of fornication before marriage and if they got married , did so for love . The culture of where you live fully accepts you and you should not really care about the culture you left . You should simply ignore him and as much as possible , block all contact from someone who tries to screw you over , but because of where you are , no one gives a damn except possibly followers of your culture , who are probably few and far between in Germany . It makes our couple so upset and we want to confront him . There ' s no point . If you ignore him this issue will go away . What should we do to stop him ? Nothing . Ignore him . Cut him out of any social life contact . What should we tell the people ? Tell them he ' s full of shit , but you don ' t care anyway . How should we react . With as much indifference as possible .
