U2720Q, yellow/green/red line
Good day,
I am facing with the problem where vertical line occurred on my screen. First time it was red line and it disappeared for about 2 days, but just after these two days line occurred again and turned to green/yellow/orange (color is changing). I bought my screen about 1.5 week ago. What should I do?

Take the PC and video cable out of the troubleshooting. Run the stand alone U2720Q Built-in Diagnostics. See page 55 in the online U2720Q User's Guide.
If the line appears during the stand alone Built-in Diagnostics, DELL-Cares will need to see pictures.
If the line does not appear during the stand alone Built-in Diagnostics, the fault is not with the U2720Q.

Update = After verifying ownership and completing troubleshooting, a DELL agent setup a refurbished exchange.
