Quest for 800x480

Exactly what?

He can't get the monitor to recognize the resolution. Thats the problem.

Sorry, I wasn't too clear was I?

Its a pity Lilliput doesn't step up and its engineers suggest powerstrip timings, rates and porch settings that give optimal results. Has anyone asked though, I wonder?

I've asked Xenarc via telephone. They claim the settings on their website work. I seriously believe that they understand that their current 7" display WILL NOT display 800x480 but they still claim it will. I have not heard a report of even *one* person getting 800x480 to work on their Xenarc (or Lilliput). What a scam...

What are the adress for Xenarcs homepage? *noob*

Did you even try?

just for the record.. the onboard videocard on the asus pundit supports the 800x640 right out of the box... since there are no skins for media car made in this rez i just use the 800x600

800x640.... thats great...exactly what we are all trying to get here

800x480

sheesh

my turn.... I don't understand

ha ha ha ha

man.... getting it right is a frustrating enough process......

It seems people are finding various ways to get their cards to output a 800*480 signal that is displayed (e.g. in my case using the Xenarc timings), but no one can get the monitor to recognise it as 800*480 (e.g. in my case it is recognised as 852*480).

I don't know enough about what goes on inside the monitor to understand what effect this has. The horizontal scan lines are analog signals. The card is forming this analog signal to represent 800 pixels per horizontal line. I assume the monitor samples the analog signal to produce its 800 digital pixel values to drive the LCD. If the monitor just sampled at 800 points in the analog signal, then it wouldn't matter that the monitor thought it was a 852 pixel line as it would be getting the right answer for the wrong reason. However, if the monitor is doing something more sophisticated and trying to interpolate from 852 sample points to 800 pixel values, then that wouldn't produce the right answers.

Can anyone explain what actually goes on inside the monitor to convert the analog horizontal scan line signal into the 800 pixel values that drive the LCD? Sorry for my lack of knowledge, but this question is really bugging me.
