Resolution hax

post #1 of 9
Thread Starter 
Finally got around to S-OFFing my phone, so I can edit my DPI settings.


Those of you who read my thread on how resolution works on a smartphone should know that Android bases it's resolution not on the physical number of pixels, but on a fixed DPI value and the aspect ratio. This allows Android apps to scale to fit any number of resolutions, so an app on my 800x480 HTC Desire will look the same as it does on a 960x540 Motorola Atrix.

The fun part is that you can edit this value. My Desire's DPI is set to 240 by default, but I have sharp eyes, so I figured I would increase it (technically its a decrease, not sure why though). I dropped it to 200 DPI and after a quick restart got an instant 20% increase in resolution.

Now my phone is behaving as if it has a 960x576 display, which is awesome,

This is cool. I have a desire(S-OFF'ed and running oxygen H-BOOT) and I want to know how you did this.

It's an extremely useful trick, but it's not compatible with all apps. For example, the Wireless tether app, the blur dialer, etc.

It's commonly referred to as "lcd density" in the build properties. The higher the number, the higher the "resolution". You have to be rooted to edit the value.

I used Root Explorer to copy /system/build.prop onto the SD card, then mounted it and changed ro.sf.lcd_density from 240 to 200 using notepad before copying it back. I don't think it works in Astro since you need to mount /system with r/w capabilities and by default its read only, even with s-off.

You have to be careful though. I tried using 220 and got a boot loop.

I notice that it doesn't work with root explorer, but that's it for me.

That's pretty nifty, makes me want to get an Android, shame you can't do this on iPhone.

Can you increase it as well as decrease, making the resolution smaller, therefore making everything bigger? I assume so, but that'd be a nice feature for those who's eyes have seen better days.
