Hi to all!

Can anyone tell me what the maximum resolution is with PicoMiteHDMIUSB for two colors and black?
Is that 640x480 or can something higher be set?

If I use higher hdmi resolution the cpu speed is higher. Does that mean my code will run faster in higher res? stan

If your code depends on any MMBasic timing such as TIMER or SETTICK then no. Those timers stay at their correct values.

Also, if your code is writing to the screen then there are more pixels to write in higher resolution. So your CPU is running faster but your video is running slower. :)
