ClickMobile client supports different screen resolutions.

Here’s a short guide for the different screens available in Windows Mobile phones.

People ask me a lot about ClickMobile’s support for different screen resolutions. While the problem is not that noticeable in laptops and tablets – it is something that requires some attention in PDA’s and smartphones.

During 2008, devices manufacturers have significantly improved the quality of their screens display, mainly in order to better compete with attractive devices such as the iPhone, and also to better support wireless Internet browsing. This trend also increased the number of different screen sizes and resolutions.

So first, to answer the first questions: Yes.
ClickMobile GUI is compatible with all kinds of screen resolutions.
It was something we worked on for version 7.5.7 SP2, and by adding a generic code that investigates the resolution and modify the user interface accordingly – we achieved the required flexibility.

While working on the fix, I discovered that many people are not completely clear about the different resolutions of Windows Mobile, so here’s a short (incomplete) guide:

Screen resolution typically stands for the number of pixels displayed horizontally and vertically.
Classic Windows Mobile devices used to have 240×320, and then came the mobile phones with built in QWERTY keyboard (AKA: Candybar QWERTY form factor) which had a square screen – 240×240.

Two of the classic WinMo models: HP iPAQ (240×320) and Palm Treo Pro (240×240) – both of them QVGA.

In many cases, screen resolution refers to the quality of the display. In other words: pixel density. The term used is DPI (dots per inch), and it refers to the number of dots that can be squeezed into a single inch. More dots means higher quality of course. The default setting of 96 dpi implies that there are 96 pixels per horizontal inch of screen area – and this is known as the QVGA. Full VGA would have 192 DPI. VGA also refers to 480×640 screens combines with 192 DPI.

Oh, and let’s not forget WVGA (Wide VGA) which will also have 192 DPI but with even bigger screens like 800×480 or 848×480.

ClickMobile on HTC Touch HD – a gigantic handset carrying a beautiful WVGA (Wide VGA) 480 x 800 pixels screen, 3.8 inches size.

And now for the juicy part:
You cannot refer to screen resolution using just one of the definitions above. In fact, if you wish to analyze the quality of the screen – you need to know both the DPI and the number of pixels.

Here’s a list of different Windows Mobile screen resolutions:

Great. So now that we know much more about screen resolutions we can easily pick the best one for our needs: small and compact or big and fancy?

ClickMobile can run on any of them.
