Perhaps you selected PnP driver what required DDC/I2C connection.
Choose other one, like Generic, something dumb enough.

Then use Generic TV driver, because DevMgr will never find your TV as not PnP capable ( for now ), so you should manually config 2nd monitor regardless what DevMgr found. Your video config will be based on 2nd output of your video card, not on monitor's presence. So stick with video setup only.
No, you don't need to do that; Display Properties:Settings should have second display because of two outputs from your video card; then click on second [2], click Advanced, then Monitor tab, Properties-> Driver, Update, No, Install from specific, Don't search,uncheck Show compatible, select Generic Television ...
See if it works that way. If not - check the second output from video card and the cable with different monitor or TV.
Straight idea - connect the cable from your primary monitor during normal session while you know for sure you did setup 1920x1080x60 - ie do hot swap DVI cable from your PC monitor to your TV.
Is it possible that the output of the OP's display adapter is configured for analog output?
Little note: as soon you use DVI-HDMI cable or dongle, you're lost DVI-analog signal, presume it's there. HDMI standard is totally digital, while DVI connector with proper DVI cable can cary separate analog [RGB] signal. Check all DVI connector ( source, target, cable, switch ) for four pins adjusted to separate wide blade (groung) inside of all DVI connector(s) in a chain.
