9.4 MHL FAQs

Q1:    

I cannot see my mobile device image on 
the monitor screen

Ans.:

   

 Please check if your mobile device is MHL 

certified.

 You also need to have a MHL certified 

cable to connect the devices. 

 Make sure that you have connected to the 

MHL-HDMI port, and that correct input 
is selected on the Monitor via the input 
selector (front bezel or OSD)

 The product is officially MHL-certified. 

As this monitor is a passive display, if you 
encounter any unexpected troubles when 
using the MHL input, please refer to the 
mobile device’s user manual or contact the 
manufacturer of the mobile device.

Attention

No video input(MHL-HDMI)

 Make sure your mobile device has not 

entered standby (sleep) mode. If it has, 
then you will see a notification message on 

the display. Once the mobile device wakes 
up, the monitor’s display will wake and 
show the images. You may need to make 
sure that the correct input is selected if in 
between you have used or connected any 
other device 

Q2.    Why is the image on the monitor display 

of poor quality?  My mobile device looks 
far better. 

Ans.:

 

 The MHL standard defines fixed 

1080p@30hz for output, and input. This 
monitor complies with this standard. 

 The image quality depends on the quality 

of the original contents. If the content is of 
high resolution (example HD or 1080p), 
then it will appear in HD or 1080p on this 
monitor display. If the original content is in 
low resolution (example QVGA) it may 
look good on the mobile device due to 
its small screen size, but will look to be of 
lower quality on the large screen monitor 
display.

Q3.    I cannot hear sound from the monitor 

display. 

Ans.:

 

 Make sure your monitor display has built-

in speakers and the volume is turned on 
the monitor side, and also on the mobile 
device side. You may also want to use 
optional headphones.

 If your monitor display does not have 

in built speakers, then you can connect 
optional headphones to the output on the 
monitor. Please ensure that the volume is 
turned on the monitor side, and also on 
the mobile device side.
