Multiple cable adapter setup not working - VGA to smartphone. All cables tested and work
- by Christopher Rucinski
Issue
Pictured overhead projector setup does not work. #1 - #2 - #3 - Phone. All cables are tested and work! The issue is the HDMI connection between cable #2 and #3.
With all other cables, the screen will automatically be displayed onto the projector screen. No extra work needed. With the pictured setup, the smartphone screen is not displayed onto the projector screen. What is the issue with the HDMI connection??
Background
We recently had to do presentations at work (school), but the administration only provided VGA means of hooking up to it. Mostly likely reason probably dealt with cost. Anyways, there are several teachers that have brand new Samsung Series 9 ultrabooks (or similar). You know, the ones without VGA support.
So I bought an adapter for those ultrabooks. Cable #5 in the picture below.
However, both my coworker and I have been wanting to just display our phone screens on the projector. This I knew would require some extra work.
What I have
VGA cable to projector (cables go through the wall)
For laptops
HDMI to VGA cable
For laptops
MHL adapter
For 11-pin microUSB phones
microHDMI to VGA cable
For ultrabooks
11-pin to 5-pin microUSB adapter
For older 5-pin microUSB phones)
Equipment
Projectors
1 projector with VGA and HDMI input (issue is coworkers forget to switch sources)
1 projector with VGA only input
Laptops
2 new Samsung ultrabooks w/o VGA or HDMI support
1 ultrabook with VGA and HDMI support
several other laptops with at least VGA support
1 tablet with 11-pin microUSB
at least 1 new phone with 11-pin microUSB
at least 1 old phone with 5-pin microUSB
Tested

Extra Notes
The 11-pin MHL adapter will not fit inside the 11-pin to 5-pin microUSB adapter so older phones can be displayed on the screen.
