Hi,

I can't seem to get the right output. The screen is still blurry.

My edid looks like this:

pi@raspberrypi:~ $ 

So I changed to:
hdmi_group=1
hdmi_mode=16

It is an old laptop screen that I hooked it up with.
The screen is this one: LP171WP4(TL)(B1)
Datasheet: http://www.panelook.com/LP171WP4-TLB1_L ... _5769.html

What am I doing wrong?

edit:
I change hdmi_mode to 47, also doesn't work.
Changed hdmi_group to 2. Same result.
