Windows Central Question
Using windows 10
I tried to use a TV as second monitor for laptop. TV fully functional with normal antenna setup.
Expected: upon connection of blue monitor wire between PC and TV, TV should boot with default settings and work as a second monitor.
Actual: upon connection, PC recognises the TV and proceeds to adjust laptop resolution. TV screen changes from black (powered) to a "signal out of range" error. Laptop screen gets name 1|2 with no other selection in the Display Settings visible. Full specs for both monitors are available in Advanced Display Settings 60Hz identical actual resolution (allowed), but different resolution Actual. No apparent effect though.
Attempted fixes this far:
All relavant drivers have been updated, uninstalled, reinstalled. No effect.
Wire tested - good connection quality both sides.
Multiple laptops tested - original laptop screen resolution doesn't always change when TV is connected. No other observations.
Connection to TV monitor is blocked in safe mode - so no methods involving safe mode can work.
Refresh Rate of TV screen is 60Hz but can be adjusted to 72 and 75. Cannot be adjusted downward using Advanced
Display Settings and any attempt to change these required admin access unless it was impossible.
TV menu offers no troubleshooting and is fully unavailable when taking input from PC.
No HDMI connection plug is seen on TV.
Restarting PC and TV too many times. No effect.
Status reads "Screen functioning normally" and Errors= false.
Connecting to a PC 3 which had no monitor causes similar effect - Signal out of range - error.
When PC is turned off message "no input signal detected" briefly shows, before clearing to black, backlit screen.
TV has no internet connection and cannot receive updates.
I assume it's an issue with windows 10, but don't know how to test. Clearly the TV was designed to take PC image input . The combining of laptop and TV screen name as one "1|2" box in settings causes alarm.
At this point, if the TV cannot function as second monitor, it will be considered useless. I will get rid of it despite my custom PC (3) missing a monitor.
