Got some photos? Or draw a layout of your room? My tv is my second monitor atm. I use KODI to watch movies and it starts on my TV and blanks out my other monitor if it is on. What size is your tv? What size is your desk? I have a 2nd tv in another room with a long HDMI that goes through the AC access in the wall and goes outside and back in another ac access in the other room. What about a TV stand behind your desk? Fitueyes Floor TV Stand with Mount swivel for 32-60 Inches TV https://www.amazon.com/dp/B01A6D9D12/ref=cm_sw_r_taa_2A01xb2N2C15G
