    Chips 6555 controller possibilities.

    Guy's, you may have read my previous post about buying a Keycorp 12.1" Digital LCD. Well i have since discovered that the LCD is a STN type (up to shi* as far as refresh rates go).

    However, It came with a Digital PCI Chips 6555 controller card. Does anyone know of any 12.1" TFT LCD's with a better refresh rate that i can run from this card?

    Another question is: I am trying to play DivX movies from this. I don't think it would be that bad if the controller had a bit more memory. It has 2mb of ram and i beleive this is what is causing it to be very slow and jerky notion during movie playback.
    Id there anyway to share the PC's memory in order to speed up the playback. At the moment it is totally unwatchable. I don't think it is entirely the screen as the card also has a 15pin vga output that i have a CRT plugged into. This also has slow playback. I had an 8mb AGP card in there previously thgat played movies fine.

    I NEED SUGGESTIONS!

    in summary,
    Is the controller a good controller?
    Can i run movies with this controller (with a new LCD, not STN)?

    Thanks guys!

    Sorry to confuse guys but it is of course a Chips 65555 not 6555 as first mentioned.

    You can definitly drive TFT's with this chipset although I really wouldn't bother! If it is barely watchable with the likes of divx then it won't obviously be any better with the better display. I have one of these on an old 486 dx2 66 laptop - it is an OLD chipset. However, lots of controllers still use them. How about Nvidia release a Geforce 4 Go on a PCI chipset that can drive LCD's - I'd like that

    As for divx playback, my laptop (celeron 433) with a 4mb ati rage lt pro managed it fine, although it could just be poor drivers? I dunno about sharing memory - I don't think this would help. My guess would be that you should look for another newer controller perhaps with more memory, although this is only speculation as I don't actually have an LCD controller

    I remember reading somewhere that divx needed 8mb of graphics memory to run - perhaps it needs a bit more than 2??

    I have this controller as well

    I also have this controller with a 10.4 Inch Mitsubishi LCD, and it absolutely sucks for DVD/DIVX, on my PII 450MHZ w/ 256MB RAM. In WINDIVD, if I size the screen down to 33%-50% of the original size, then it's watchable , but in full screen it's jerky. Power DVD 4.0 crashes when this card is in the system. Using my All-In-Wonder Pro 8MB, in this same system renders flawless playback. One of the things that I thought of doing is running dual video carrds. My would consist of a 10.4" LCD for me up front and 2 5"LCD's in the back for my kids. THen for DVD playback, I would tell PowerDVD/WinDVD to use the AIW card for playback and I would use the Chips 65555/10.4 LCD to control the system up front. With this setup I couldn't watch Movies up front, but I could still do MP3 and GPS.

    OK i have an Idea. I found on the web someone also having this problem during playback of DVD's.

    They were running windows 98.

    It suggests that if you are running Windows 98 or ME, you should run 'msconfig' and check on:

    General / Advanced / Disable UDF Filesystem

    i haven;t tried it yet but let me know how you go!
