Note 10.1 (2014) as a VGA Presentation/Lecturing tool
I'm using the Samsung Galaxy Note 10.1 (2014 Edition) to give lectures (using the LectureNotes app to write during the lectures). I need to be able to connect it to typical VGA projector. Thought it might help others to know what accessories worked to do this:
- Samsung MHL to HDMI adapter (model ET-H10FAUWE)
- HDMI to VGA + Audio Converter (made by Neet, bought on amazon)
- Optional: MoKo Samsung Galaxy Note 10.1 2014 Edition Case - Ultra Slim Lightweight Smart-shell Stand Case
The MHL to HDMI adapter is great. It did not come with a power supply but takes the same micro usb as the Note. It produces a beautiful image on an HDMI display (tested on both 720p and 1080p) and did not require any settings to make it work. In all cases it has worked without needing a power supply - presumably because it is drawing sufficient power from the hdmi port with the devices I have tried. If a power supply is connected it passes through to the Note (charging it if the power supply gives sufficient current). Connecting the adapter makes no impact on the speed of the device. Unfortunately none of our lecture theatres have hdmi connections.
The HDMI to VGA converter needs to be active (so needs power). The "Neet" one above had good reviews from people who had struggled to make this work with other devices. For me it worked straight out of the box. On a 1024 x 768 device it uses the full height of the display but not the full width: ileaves a narrow black band on the right. It is showing the full tablet image which is slightly distorted on the projector screen. The projector detected the display without problems.
For the case, I wanted one that works upside down in landscape mode so the return button is at the top left. This prevents accidentally closing the app while writing on the tablet. It also means the display cables run away from you. You need to switch off the auto brightness on the display because your hand will cover the front camera as you write and so the display will periodically dim - not that this makes any difference to the projector display but is just a distraction when writing.
The alternative method I tried to project the display was using a VNC server. I bought the VMLite VNC Server app. (The developer was very helpful and responsive.) By connecting this to a computer/laptop with a VGA connection, you can project the screen. However the VNC server significantly slowed down the tablet and made writing on the tablet less than pleasant. So I abandoned that in favour of the hardware method above.
Hope this helps someone - though your mileage may vary. (Sorry about the lack of links - not enough posts it seems so I had to strip them out).
