Guest Mir_X Posted July 23, 2009 Report Posted July 23, 2009 On the some websites they mentioned that omnia has a screen that supports up to 256k and some sites say that it has 256k screen but supports 65k (effective) what does it mean , effective ? on the other forums , some posters say omina supports 256k screen but winmo supports only 65k becuase of this it works at 65k color depth...with this information , if we install an os that supports more than 65k , can our ominas support 256 k ? what is the real answer ?

LCD is capable of 256k But Winmo Os only Supports 65k.
Guest X-Ray A4T Posted July 23, 2009 Report Posted July 23, 2009 Also as it is 400x240 we can't get better than 96k
Guest Mir_X Posted July 23, 2009 Report Posted July 23, 2009 Also as it is 400x240 we can't get better than 96k hmm ,in this case it is a hardware limitation upto 96k
Guest Mir_X Posted July 23, 2009 Report Posted July 23, 2009 in the andromnia topic ; somebody said that : Who said that it supports 256k? While LCD screen can be 24-bit compatible (which I doubt), XScale framebuffer still is 16 bit max, unless you use YUV overlay mode (which is indended for movie playback only). Its a hardware limitation.
Guest Ingvarr Posted July 23, 2009 Report Posted July 23, 2009 (edited) First of all, many LCDs are 6-bit component on the data bus level - are you sure Omnia uses 8-bit component LCD? What is the source of this information? Second, XScale CPU LCD controller is defenitely 16-bit framebuffer max. Third, TCPMP and CorePlayer use dithering algorithms, so they can make gradients appear smooth (no banding) even on 16-bit display. http://en.wikipedia.org/wiki/Dithering#Dig...mage_processing The test with video player can be representative only if you making sure that its not dithering. Technically ads saying that device supports 256k (24-bit) color, while hardware in fact limits is to less is a very common case of false advertising (another being specifying totally unreal battery life times). Don't trust ads, trust only manufacturer-issued hardware spec technical documents. Edited July 23, 2009 by Ingvarr

Yes, and you can check the specs for Omnia CPU yourself - they are available on intel developer website, along with docs for direct hardware programming, etc. There is a support for 16-bit RGB framebuffer max.

Guest StarVision Posted July 23, 2009 Report Posted July 23, 2009 Thatz why u will feel that Andromnia's colour is so vivid
Guest Mir_X Posted July 24, 2009 Report Posted July 24, 2009 (edited) Thatz why u will feel that Andromnia's colour is so vivid because of cpu hardware limitation , there will be no changes on colordepths on andromnia...(as ingvar told above) Edited July 24, 2009 by Mir_X
Guest hutame Posted July 24, 2009 Report Posted July 24, 2009 interesting subject, i saw many 65k screen, in my opinion omnia has 256k screen, it'd better technical evidence.
Guest Mir_X Posted July 24, 2009 Report Posted July 24, 2009 (edited) interesting subject, i saw many 65k screen, in my opinion omnia has 256k screen, it'd better technical evidence. i think he said that the screen in question may be 24 bit but the cpu supports 16bit max because it has 16bit framebuffer max...as a result you can get 16 bit colordepth from the omnia Edited July 24, 2009 by Mir_X
Guest hutame Posted July 24, 2009 Report Posted July 24, 2009 acceptanceable, actually, we need a test program for omnia.
