Best resolution for both Iphone/Ipad

[Evilized79]

which screen resolution is best to use when I want to make a game for both ipad and iphone?

I noticed when I use 1024x768 that it works great for ipad but when compiled to iphone it shows black bars on the side.

anyone know a resolution which will enlarge to full screen for both devices?

For ther moment, there is no resolution that will fit the screens totally. If you make your application in 960x640 you will have horizontal bars. So it is really up to you?

So far I think the best option is 960 * 640, because it looks perfect on iPhone / iPod and iPad the horizontal bars are not noticeable. Francois screen bug that does not allow a resolution to fill the entire screen persist?

I do everything in 960x640 and it comes out great on iPhone 3GS, iPhone 4, and the iPad 2 that I use for testing. I found it necessary to get a low-end 3GS in order to ensure proper frame rates as some of my older apps were chewing up too much memory and GPU. The black bars at the top and bottom of the iPad 2 when running at 960x640 actually give the app a really good golden ratioish letterbox appearance over the squarish look.

What bug? The bugt we had on the ipad and that blocked us for month is corrected...

[Koji_Kabuto]

That bug Francois speak, that of the black bands are horizontal and vertical depending on the device resolution. If resolution is 960 * 640, on the iPad horizontal black bands appear if resolution is 1024 * 768 iphone vertizales bands appear on the iPhone.

It is not a bug! It is a choice. As the screen symetry is not the same between 960x640 and 1024x768, you have to have bars on the display.
