Hi everyone,

 
I've a PCB with an AD8194 and AD9880. The AD8194 mux is connected to a DVI and HDMI connector. 

 
I've a trouble with the AD8194. The AD9880 doesn't detect signal with some DVI sources like personal computers. 

 
If I remove the AD8194 and I do a bypass with some wires, the AD9880 detects the video source. Please, could anybody help me? 

 
Thank you 

 
Best regards

 
Jose

    Hi daverowe,
    
 
    I've been testing with three kind of monitors:
    
 
    One of them has a DVI input (it has an AD9887), it works fine 
    
 
    Other with DVI input and AD9880, it works fine
    
 
    Other with DVI and HDMI inputs (AD8194 and AD9880), The DVI input doesn't work fine with two PC
    
 
      
    
 
    The PCs have the same HW
    
 
      
    
 
    They have a main board with an Intel G33/31 express graphic board integrated (DVI, HDMI and VGA outputs) and an extra graphic board (Gigabyte 7G5818A Geoforce 8500 GT) 
    
 
      
    
 
    With Intel I don't have any problem and all monitors work fine in HDMI and DVI
    
 
      
    
 
    With Gigabyte (7G5818A) I can't see anything on the monitor with AD8194, only sometimes the image appears for 1 or 2 seconds (with wrong colours) but quickly disappears. The rest of the monitors work fine
    
 
      
    
 
    If I remove the AD8194 I don't have problem
    
 
      
    
 
    Thank you very much
    
 
      
    
 
    Regards
