A usable work around

Thanks sconemad, "alt" and drag using the Florence virtual on screen keyboard works a treat. I will try to deliver some feedback to Real VNC about the default window size problem.

Re: VNC viewer window too big for 800 x 480 screen

Thanks for your reply. I'm afraid I wasn't explicit enough, the problem is with the VNC Viewer application window at start up of the app, long before I try to connect to the robot. I tried booting to HDMI mode on a monitor rather than the 7" screen but I get the same result, the VNC Viewer app fills...

VNC viewer window too big for 800 x 480 screen (Solved)

For some time I have been using a Pi2B with an official 7" touchscreen as a remote controller for my Pi3b brained robot. It uses the installed VNC Viewer to connect headlessly with the robot. I have just (17/06/2017) carried out an apt-get dist-upgrade and find that the size of the updated VNC Viewe...

Re: DSI Raspberry Pi 7" Touchscreen

I can confirm that the HDMI connectors work with both the CSI camera and the DSI 7" screen. The downside is that of my five HDMI cables only one of them will work in this context although they all work as bog standard HDMI cables.

Re: OpenCV 2.4.9 compiled libraries for Raspberry Pi (RPi)

I've found out what the problem is, the cv2.so file is a different version from the libraries. It seems that the lib files are for version 2.4.9 and not 2.4.11 as labelled. I found a previous cv2.so file I had on an old wheezy sd card and replaced the installed one. It worked - but cv2.__version__ c...

Re: Align Display

You might find that the glass screen has slid a little relative to the metal base. Some of the early screens had a faulty adhesive which when put under tension would creep. This was usually a result of the fixing screws pulling the metal frame while the glass was restrained by the case. One solution...

Re: official 7'' display

My limited experience using the HDMI cable adapters with the screen is that only one of my HDMI cables works, three others don't. All of them work between my TiVo box and the telly so I don't know how one would test them other than trial and error.
