Hello,

did anyone ever change the display of an A21p to XGA?

Here's a Mainboard from an a21p that i'd like to fit in an A21m with a toasted board. After powering on the screen is "zoomed" and some parts of the picture are missing

You need to get an XGA cable. Go to this site to look up what you need.

Can you give me the 7-character product numbers of the A21p and A21m? Just curious what you have.

Welcome to the forum!

Hello pianowizard,

funny, that was my first posting

I've been reading for a long time here, upgrading my 770ED, X, Z and 760XL and so on

The cable belongs to the XGA-display, i did not open the whole display - knowing the T23 recognizes the Display via the correct cable.

Currently no idea

edit:
2629-HTG broken A21p-base - just took the board from it
2628-GWG toasted A21m
2629-ABG still running

Check Display Properties to see if the resolution is really set to 1024x768. If it's a higher value, that would explain your "zoomed" problem.

Another thing is, that page I linked to shows three different kinds of XGA cables. You might need to get one of the other two.

Hello,

just to add some details:
A21p-board: 08k3265
A20m-board: 08k3264

"zoomed": even in BIOS the screen is zoomed, the lower third is not visible. XP did not start correctly, ended with a bluescreen

Getting the other LCD-Cables may be complicated in germany, i should better seek a 08k3264 board - or do you have any idea of prizing?

idea: Bios "update" with a A21m-BIOS?

I had this problem once, when I put an SXGA+ screen from a T42 into a Dell Inspiron 4150 which was designed to use a UXGA screen. What's different from your case was that I could load Windows 2000 just fine, no blue screen.

I think the BIOS might be a problem, but flashing an A21p board with an A21m BIOS might permanently damage the board. The easiest and safest thing would be to buy a whole new A21m. They are under $150 these days.

Next week i get an A21p with graphic errors- the onboard-graphic should be defective, not the LCD. I'll put this board into the new A21p and will try to flash the partly broken A21p-Board - frying the broken one is not a problem

more next week,

thanks, Martin
