[NAME]  You said "Inspiron 5676", so is that what your account says? You can enter the Service Tag from on the Support page and it will tell you the model. Tag is on the back of the PC. I think [NAME] might have asking about the model of AMD video card since you mentioned Inspiron 5676 and AMD. Has this problem with TV always been an issue or is this something new? What port are you using on the AMD video card in PC and what port on the TV? You said those settings I suggested are already off, but have you tried just setting Win 10 to turn off display after X min rather than turning the TV's power off? Do you have all the latest drivers installed?
Technically it's a tv. what happens is i leave my computer on but turn my tv off. i come back later, pc's still on, turn tv on, tv show's static, not a no signal notification. just white static. if i turn the pc off and back on, bam everythings back to normal. i've changed the hdmi cord twice, and the problem only seems to happen when i turn the tv off, if i switch sources, say between my pc (hdmi 1) to my xbox (hdmi 2) there are no problems. but turning the tv off seems to kill the connection. it doesnt happen everytime but it has happened enough to make it aggravating
