    Question Interpretation of timings...

    Ok i hv CTF-800 (bought from cartft - i live in Greece) and i'm trying to operate the monitor with Intel's 82865G graphics chipset... unfortunatelly, as mentioned, 865 does not support 800x480 resolution, so i'm trying to accomplish that via the hack which was mentioned before...

    Looking for the CTF800's timings i found these:

    CTF800 timings:
    Pixel 33,6
    H 37, 8, 43
    V 15,3,16
    800x480=800,37,8,43,480,15,3,16,33600,278

    Generic timing details for 800x480:

    HFP=37 HSW=8 HBP=43 kHz=38 VFP=15 VSW=3 VBP=16 Hz=74

    VESA detailed timing details:

    PClk=33,60 H.Active=800 H.Blank=88 H.Offset=21 HSW=8 V.Active=480 V.Blank=34
    V.Offset=15 VSW=3

    Linux modeline parameters:
    "800x480" 33,600 800 837 845 888 480 495 498 514 -hsync -vsync



    which i'm trying to interpet to that .reg file (specificly the bold ones):


    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Video\{71F7F719-E874-4707-9A40-55B83F887A1E}\0000\Config\1\Port\5\General]
    "Rotation"=dword:00000000
    "Flip"=dword:00000000
    "Edid"=dword:00000000
    "EdidNotAvail"=dword:4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Video\{71F7F719-E874-4707-9A40-55B83F887A1E}\0000\Config\1\Port\5\Dtd\1]
    ; 38550
    "PixelClock"=dword:9696
    ; 800
    "HorzActive"=dword:320
    ; 40
    "HorzSync"=dword:28
    ; 80
    "HorzSyncPulse"=dword:50
    ; 0
    "HorzBorder"=dword:0
    ; 232
    "HorzBlank"=dword:e8
    ; 480
    "VertActive"=dword:1e0
    ; 61
    "VertSync"=dword:3d
    ; 3
    "VertSyncPulse"=dword:3
    ; 0
    "VertBorder"=dword:0
    ; 142
    "VertBlank"=dword:8e
    ; 25
    "HorzSize"=dword:19
    ; 16
    "VertSize"=dword:10
    ; 0
    "Flags"=dword:0



    I know how to convert decimal to hex, but I cannot match the meaning of the numbers..

    So, please somebody help me with the correct match...

    Hello..

    Please, can anyone help me translate these timings provided by CarTFT:

    CTF800 timings:
    Pixel 33,6
    H 37, 8, 43
    V 15,3,16
    800x480=800,37,8,43,480,15,3,16,33600,278

    Generic timing details for 800x480:
    HFP=37 HSW=8 HBP=43 kHz=38 VFP=15 VSW=3 VBP=16 Hz=74

    VESA detailed timing details:
    PClk=33,60 H.Active=800 H.Blank=88 H.Offset=21 HSW=8 V.Active=480 V.Blank=34
    V.Offset=15 VSW=3

    Linux modeline parameters:
    "800x480" 33,600 800 837 845 888 480 495 498 514 -hsync -vsync


    to these in the .reg file:
    PixelClock = Horizontal geometry Pixel clock
    HorzActive = Horizontal geometry Active
    HorzSync = Horizontal geometry Front porch
    HorzSyncPulse = Horizontal geometry Sync width
    HorzBorder = ?
    HorzBlank = ?
    VertActive = Vertical geometry Active
    VertSync = Vertical geometry Front porch
    VertSyncPulse = Vertical geometry Sync width
    VertBorder = ?
    VertBlank = ?
    HorzSize = ?
    VertSize = ?
    Flags = ?

    VertSize = ?
    Flags = ?
    ok..

    I tried to match the quoted timings but i am not sure if they are correct:

    PixelClock = Horizontal geometry Pixel clock ---------33600
    HorzActive = Horizontal geometry Active ------------800
    HorzSync = Horizontal geometry Front porch--------???
    HorzSyncPulse = Horizontal geometry Sync width ---8
    HorzBorder = ? -----------------------------------------0
    HorzBlank = ? -------------------------------------------88
    VertActive = Vertical geometry Active ---------------480
    VertSync = Vertical geometry Front porch-----------???
    VertSyncPulse = Vertical geometry Sync width -----3
    VertBorder = ? -----------------------------------------0
    VertBlank = ? ------------------------------------------34
    HorzSize = ? -------------------------------------------25
    VertSize = ? -------------------------------------------16
    Flags = ? -----------------------------------------------0


    Is these matching correct??

    Furthermore i don't know which numbers match with HorzSync and VertSync (Front Porch for PowerStrip), noted above with "???". Please give me your knowledge..

    have you tried googling custom res intel 865? i dont remember exactly what terms i used or the results, but it was a good try. you could probably make more sense of the results than i could.

    personally, I just added a new agp card on my mobo, as no one could give me some answer or guidance modifying 865's driver..

    if there is any new info about this issue please someone post it..
