When choosing a tablet or monitor it's important to make sure that it has a resolution that is equal to or higher than 1360 x 768 pixels.
Screen resolution refers to the clarity of the text and images displayed on your screen. At higher resolutions, such as 1600 x 1200 pixels, items appear sharper. They also appear smaller so more items can fit on the screen. At lower resolutions, such as 800 x 600 pixels, fewer items fit on the screen, but they appear larger.
Native Resolution
FLEX is designed to run natively at a resolution of 1360 x 768 pixels, meaning that what you see on your screen will be exactly how it was designed.
Higher Resolution
If you run FLEX at a higher resolution, you can either run FLEX in a window that will match the native resolution but won't fill the screen or it can be maximised and FLEX will fill the screen and move the controls so that the spacing between them is proportionally correct but controls will not scale up (get bigger).
Lower Resolution
If you run FLEX on a resolution lower than 1360 x 768 pixels, you will see that controls will start to overlap - how much will depend on the resolution you are running.
Windows Screen Scaling
It's worth mentioning screen scaling in Windows, this feature can be used to make items on the screen bigger (fonts, icons, images etc.) - it also works with FLEX. If you change the scaling percentage then FLEX will get bigger, but bear in mind if you scale too much then controls will start to overlap, in the same that lowering screen resolution causes control overlap.
It is worth experimenting with different resolutions and scaling, in our experience if you set the resolution to 1920 x 1080 pixels then you can safely set your scaling to 125% - anything more than that and things start to go horribly wrong!!!!
