I am attempting to set up a "video wall" w/ 3 TV's. At the computer store I don't think they understood what I was asking for. I believe they thought I wanted a computer w/ a 3 monitor desktop. They sold me a computer & said I needed a Nividia 3060 graphics card, which I bought & they installed. On the computer they put the VLC media player. After a lot of struggling w/ resolutions, orientations, & audio issues on the graphic's card. I can only play DVD's on my 4K TV's. Not even close to the resolution I want from the system. I downloaded a blue ray player. The 2 players were getting called up at the same time & crashing. I deleted the newer DL'd one & am back where I was. I think there may be a HDMI cabling problem as the anti-copy stuff may be kicking in. I thought when I got the graphic's card it would have an input for my amp (card has no input) so I could use the 3 TV's as one TV.. I was hoping I could play my 4K player into my 4K TV's. I question it is possible? If it is, I don't know what to do next.. help please..
