Up until yesterday evening I have been able to use my Emerson 32in HDTV as a second display on my PC perfectly fine. Now when I turn it on, as of last night, i'm getting one of two messages on the TV screen. Either "resolution mismatch! Change device resolution" or a much longer error that begins with "The TV does not support the output format, video resolution and/or refresh rate sent by the connected device". No settings have been changed, the resolution and refresh rate haven't been changed since i've owned the TV. I've tried several different refresh rates and resolutions and nothing has worked. ANY help would be appreciated.

HDTV model: LC320EM3F A
Graphics Card: GTX 660ti
Graphics driver:9.18.13.2018

Thank you!

I checked your manual and found this info: Try the lowest setting and see if you can get it back on.

The following video signals can be displayed:
Format Resolution Refresh rate
VGA 640 x 480
60Hz
SVGA 800 x 600
XGA 1,024 x 768
WXGA
1,280 x 768
1,360 x 768
Other formats or non-standard signals will not be displayed
correctly.
Note
•• Please purchase the VGA cable that has a ferrite core.
•• The following operations may reduce noise.
- Attach a ferrite core to the AC power cord of your PC.
- Unplug the AC power cord and use the built-in battery of your
PC.
