Windows 10: Raspberry PI4 + Official Touch Screen => Not touch and bad resolution

Hi,When installed the last release of Windows 11 on ARM, on a raspberry PI4B equiped with its official 7'' touch screen, I have several problems :1. Screen resolution is set to 800x600 under W11Pro64, however the touch screen resolution should be 800x480,2. W11 desktop on the screen is stretch alignement vertical, but horizontal is not full screen black parts on left and right.3. Not touch is available. Is the RPI touch interface compliant or do I have to use another part for the screen that uses USB touch instead ?Thanks for your feedback,

:)

Touch screens

I can do 60 words per minute on my phone, perhaps more now as I've got used to the phone. ( htc desire z, using the stock onscreen keyboard)

Touch screen + predictive text I recon I could equal my keyboard typing speed. Maybe beat it depending on how advance the predictions are.

( hard to use predictive software on traditional keyboards as there is no way to quickly choose the suggested word, where as touch screen keyboards can have the suggested words appear above the function keys)
