HP LAPTOP LCD FUZZY

[[email protected]]

Hey guys i hope ya can help me out for a sec. I have a HP laptop that
someone gave to my shop. The screen was messed up and i figured it just
needed a new part. I called a few laptop repair places and they all
told me it was the LCD. So i hoped on ebay and got a decent one tested
working. Same problem. Its fuzzy. When ya first boot it and you see
the HP logo, or BIOS its off color and fuzzy like i have tried 2 LCD's
what else could it be?

Not enough info, Grasshopper.


If it's okay once your're booted, it can't be the LCD.


If you mean by "fuzzy", that the letters of the BIOS setup are odd
widths and heights, and if you type a row of vertical bars:

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

some are one pixel wide, some are two, then the problem is simple.

The LCD has a fixed number of pixels across, say 640, 800, or 1024.

Your display driver is set up for a different number of pixels across.

So the poor LCD panel is receiving 1.33 pixels per slot, and it
sometimes displays one, sometimes two pixels per bit.

The solution si to go into the BIOS setup and look for a setting to
change the video mode on bootup.

What I suspect is that nothing is physically wrong with it. You have set a
video mode that isn't native to the LCD, such as 1024x768 on a 1280x1024
display, or the other way around. Try all the video modes until you find
the one that is sharp.

No... Change it in Windows. Bootup is always 640x480, isn't it?

Bad video memory. If you are lucky and the machine uses 'shared video
memory', e.g. it grabs a portion of system memory for use as a video
framebuffer, then you could just replace the system RAM and all will be
well. If not (i.e. it has discrete video ram), then you're screwed. Throw it
away unless you're very talented with SMT rework and have the correct ram
chips to replace.

But I see that the original poster reports the problem at bootup. Hmmm...

Try hooking up a known-good monitor to the monitor connector on the
laptop. How does that look? Let us know.

Good tip. Now why didn't I suggest that
