    Question Has anybody ever got lil/Xen screen to clock onto native res?

    Hi
    I have had every screen going and tried lots of timing paramters with all the screens and I have never managed to trick the vga controller into displaying 800x480 natively.
    The only screen I have ever managed it on is the first generation xenarc and it looked amazing, like a tft screen should.
    I have tried on a second generation "res sensing" xenarc and it even if it accepts 800x480 with tweaking and fills the screen it still doesnt match the pixels correctly.
    I have tried the liliput and it gives the same blurred image.
    The only current screen I can get a good image on is the 8 inch lilliput which is 640x480 proper clocked image.

    So, has anybody ever managed to trick the vga controller on a widescreen screen to clock native resolution? If you have can you post timing parameters.

    The ones I use are:
    HORZ:
    Active 800
    FP 72
    SW 56
    RP 72
    TOTAL 1000

    VERT:
    Active 480
    FP 20
    SW 5
    RP 20
    TOTAL 525

    The above fools the screen into thinking its 640x480 and this seems to work on all controllers I have tried, but doesnt give a clean image.

    Unhappy

    Yea I got the same problem. I could never clock it to match exact pixels (by adjusting phase/clock) so the texts are always blurred (well, not very but quite). Also when I get the clock/phase pair that I like, if the screen's power is switched off and back on, all settings (clock/phase) will be lost! The fonts are blurred again and sometimes even the entire image goes off the screen.

    Another issue is that the "auto-tune" feature on my Lilliput gives different result everytime, sometimes even making the whole image off the screen, not mentioning giving a pixel-clear image.

    Anybody have a clue on these?

    Apparantly the new Xenarc displays sense and lock onto 800x480 properly. I'll be able to find out in a couple of weeks when I get a new one as a replacement for my old Xenarc (the little 15 pin connector has broken ), and if I can find a VGA card for my carputer that can display 800x480 (the onboard on my Epia won't)

    Yes this is what I have been told by the manufacturer gain. Though they dont always understand what I am saying because of the language barrier so I was unsure.
    Until I see an LCD screen doing what it should, Im going to stick to the 8 inch version that works properly.

    its sounding more and more like i should spend the extra $$ on a xenarc. please post a comparison between the old xenarc and the new one when you receive it. i'd really like to know if it truly is brighter than the old one.

    But it depends on who you buy the xenarc from. I bought a few a month ago and they were still the old vga board. I am in the UK so you may have more luck in the US.
