6.3. There is no input signal 

Check the source 

Check whether your source is powered on and configured properly. If the source is 
a  computer,  then  verify  that  the  DVI  output  is  selected  and  active.  Try  restarting 
your computer; if you get a picture during the booting process, you have to review 
the graphics card’s driver settings in the operating system. 

Check the EDID 

Maybe the data rate is too high for that type of cable. Try switching another EDID 
to  the  inputs  with  lower  resolution.  If  the  source  is  a  computer  and  you  are  an 
expert user, you can try modifying the refresh rate, so you would be able to get it to 
work at higher resolutions over a noisy connection.
