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