until now, I used the well known small OLED and TFT displays, up to 2.8", without issues.
Now I need something much larger: say 4.3" as very minimum, 7" if possible.
Resolution is not critical; 320x240 or 480xsomething would suffice.
Touchscreen (capacitive) would be great, but not a deal breaker.
Could you suggest a well-supported TFT display within these parameters, to be used with a Teensy 3.x or 4.x ?
Possibly < $70 (I've seen some nice 7" displays with an embedded "smart" controller and firmware, but Eur 110+, ouch!)
Some alternatives are somewhat more expensive and at first they were very limited with what could be obtained from them, without forgetting the learning curve, however, after some time I think I have already managed to make them compatible with teensy 4 and teensy 4.1. GDTeensy4X
PS: I was very interested in using the SDIO reader to handle the media files that the gameduino can do: jpg, avi, png, jpg image cells and assets). You just have to build a good shield, connect some few wires and that's it.
Here is the Gamedunio 3X Dazzler with the Arduino shield that gives more details, Video output: HDMI 24-bit at 1280x720 (720p) with 48 KHz stereo audio. Note, unlike the Gamedunio 3X that included a screen, I don't think the dazzler has touch support even if your HDMI device has touch support:
