Hi all, I'm a complete newbie to Rpi and really enjoying the fun with having one that will link to our amateur radios. My first experience with Rpi was some nice years ago when I set up a Rpi to receive and forward flight tracking information to Flightaware, it is still pounding away in our attic. At that time I bought a 7 inch LCD Screen from a company I think was called Wave, it came with an image which allowed me to control the Rpi by using the captive screen, just like a touch screen. I put the screen safely away since 2015 and just now when I bought a Rpi 4 I hooked the screen up again.
Of course it works as an HDMI screen on my Rpi 4, albeit that it only covers about 4/5 of the screen.
So on researching I have added a few lines of code to the config.txt file
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 6 0 0 0
hdmi_drive=1
The above were missing from my original config.txt file except for hdmi_mode which was set at 4.
The 87 makes my screen output massive so I've changed that back to 4 and then 7, as I thought perhaps it needed 7 for the size of screen, so we are back as is, covering 4/5 of the LCD using HDMI output from the Rpi 4.
I also downloaded some drivers, from a Wave site, which I saw was recommended for the touch screen part, but didn't solve that part. This is good fun.
Would anyone have a similar screen that perhaps works on a more recent Raspbian image that I might get some ideas from?
Thanks for bearing with me, please delete if it's not appropriate for this group.io.
Thanks, Ian.
