STM32F746G-DISCO display panel choice and alternatives

I bought a STM32F746G-DISCO board and have decided that a board like it will fit the needs of my project. Are there any companies that make development boards with this MCU that can use a larger LCD display? The disco board has a 40 pin RGB interface with the touch pins combined within the 40 pins and I can't seem to find a larger LCD panel that has this connector. Do any companies make other boards for this MCU?

I have tried to contact them, they don't even list this display on their product page.  When I tried I got no response.  Is it possible you can find your response so I can send to other then the web page address?

 ,

 ,

Thank you for your response.

♯ 3 is definitely beyond my capability. I am a software guy, and need a hardware plug and play solution, unfortunately.

♯ 2 seems interesting, I will look for these devices.  ,Do you have a reference to any?

♯ 1 I have looked into this, I have even thought of building an adapter that uses separate ,touch pin and integrates them to match the 746g connector.  ,Since I can't build this myself, and I can't find one I have to find a different solution.

Alibaba is good for higher quantity orders. If your minimum order is one or dozen pieces then Aliexpress might be a better choice. If an item is listed, price is listed and you can buy immediately.

32F769IDISCOVERY is

.

B-LCDAD-HDMI1 (MIPI-DSI to HDMI) is

.

I'm quite sure that you can buy these at DigiKey, Mouser, Farnell, etc.

As for the panel driver boards, just open Aliexpress.com web page and search for the numbers.

For example, if you search for number

32344321657 

it will open

Yes definitely at DigiKey and Mouser, run about $30 USD

The connector is the same as the one on the Arduino OTTO STAR.

I'd like to see a board with a VGA/DVI connector, got plenty of cheap monitors. Would take a F7/H7 DISCO board with an HDMI

We buy one, two and sometimes four units at a time. We contact the manufacturers directly and you can too. We purchase lots of stuff from China. Alibaba and Aliexpress and taobaofocus, they're all giant online catalogs, but you don't have to buy through them, you get better service by establishing a relationship directly with the manufacturer.
