hello guys. i hope someone can help me. just like the title says, ive been having trouble. i also have a few Startech adapters but not sure if imm working them correctly. i have a USB32HD2 adaptor,  i have a MST14DP123DP and a random hdmi 1x3 splitter. do i have the correct adapters or did i just wasted money? All i wanted to acheive is just have extended support on my monitors. no laptops or anything involved. also, if it matters, i have a geforce rtx 2070 super graphic card and a ASUS B550i motherboard. thanks in advance for any kind of help.
