EPIA-M 848x480 and 800x480 resolutions - I do not give up

**mpattonm** · 10-18-2004, 06:11 AM

Hi guys,

just want to let you know that I do not give up the fight for working 848x480 and 800x480 resolutions on CLE266 and Lilliput combination under WindowsXP.
Here is the status from last friday:

------------- sorry for keeping contact undisclosed ---------
(from VIA)
Dear Pavel,

It must to request a special BIOS for 800*480 resolution,

Could you provide the panel and SPEC for me??

Best regards,

Dear Thomas,

sorry for exceptionally late reply. I have been fidling around the driver you have sent and i must say a LOT has changed since I have seen last beta driver. Basically, all the complains I have had for this drivers has been solved. There is no such issue with BIOS part, nor the driver part. Unfortunatelly, I must also say I can only use 848x480 resolution on very narrow number of displays. Is it becuase timing is not well tuned? In any case, both multisycn NEC, HP and Samsung LCD flatpannels plus some Samsung CRT displays are displaying this resolution correctly now, while Panasonic 7,2" LCD does not. Which is painful because this LCD is the original reason for this widescreen support.

In such a cae, 800x480 resolution might be solution for us. Is it hard to implement in BIOS/driver?

Also I have to admit we have skipped TV out part qualification, since we have no plans for its use. Please let me know if you want us to test it anyway, we will be more then glad to help you out.

Or is there anything else we could help you with?

Looking forward to your feedback.

Best regards,

---------- and my reply from today ------------

Dear Thomas,

I have done some testing on the LCD panel we are talking about we are having issues with. I have taken nVidia AGP addon card, installed WinXP Detonator drivers 66.81 from nVidia and using PowerStrip (http://entechtaiwan.net/util/ps.shtm), I have setup the customs resulution and verified setting for both 800x480 and 848x480. Attached please find detailed timings I have obtained from running Powerstrip. However, I have got very best results running 800x480/16bit/72 Hz (standart Windows timing) - what is the second attachement. I would even say this one is working like a charm.

Will these data be usefull for you?

Thank you for your support,

So does it work nice now?

Give up with 848x480, don't even mention it again (please)

I've NEVER had a problem with getting 848x480 to work, however, getting 800x480 is the golden dream of all of us here!

They are working on BIOS/driver combo that supports 800x480 right now. Based on previous experience, its beta could be out somewhen next week. Lets only hope 800x480 will be implemented correctly, unlike 848x480 in its previous version, where some frequencies were a bit non-standart so Lilliput did not sync to them at all. Thats basically the reason why I have sent PoweStrip pics to VIA.

**knubile** · 10-18-2004, 09:54 AM

You actually got someone at VIA to look at an issue you have!?! Wow!
They don't seem to respond to anything I ask or anybody else asks on the viaarena forum.
I wanted to know why bass or treble control is not supported and when a new vga driver/bios combination will come out supporting VMR9. The MII supports it but apparently the bios for the M can't support the new VGA driver. The MII and M both have the same CLE266 chipset.
How did you get any help from them?

Nope, I have no relationship with VIA. Is it what you want to ask in fact?

Hey, I need to keep my contacts and their source secret. For now.

Anyway I will ask for VMR9 support as soon as I get my hand on these drivers.

Please keep us all updated on this one. Thanks for not giving up!

**mpattonm** · 10-19-2004, 04:33 AM

now you can help. any tech spec of LCD panel / decoder of Lilliput will be more then welcome:
------------------
Dear Pavel,

In fact, our RD of the graphic team can help to adjust the 800*480 resolution for you, but we need you provide this panel for us.

Can you sent the panel SPEC for me first??

Best regards,

I found this, if it helps.

3. PLE133/PM601/KLE133/MVP4 DirectDraw Display Driver Ver 1.661 - For CE .NET 4.0 & 4.1

(3/21/2003)

This software package release is version 1.661.Net. The DirectDraw display driver supports several display device configurations, including a CRT monitor, an LCD panel, both a CRT and an LCD, both a CRT and a TV, and a TV. The driver is designed for display resolutions of 640x480, 720x480, 800x600, 1024x768, 1280x1024, 1280x768, 1600x1200, 800x480, 848x480 ; color depth of 8, 16, 32 bits; screen refresh rates of 50, 60, 75, 85Hz;TV modes of NTSC and PAL. TV display is optimized for VIA's VT1621 TV encoder.

I guess that means you can get 800x480 on the older epia and epia v boards that use those chipsets? Theres a windows CE.net driver for the CLE266, but it doesn't list the new resolutions supported for that chipset. Maybe worth investigating if anyone here is running windows ce 4.1, 4.2, or 4.3
