I can't disable fuzzy format match

[ghost]

I've edited /boot/config.txt and added this line:
avoid_edid_fuzzy_match=1
But edidparser still promts: Enabling fuzzy format match...
Raspberry selects lower resolution, because it has higher mhz

avoid_edid_fuzzy_match was removed from firmware in August 2012 so it will have no effect.

You'll need to post your edid and explain what hdmi mode you are getting and what mode you think you should get.

@popcornmix any ideas?

The actual edid.dat file would be more useful. Can you upload to a hosting site (e.g. dropbox/google drive) and provide a link.

Actually, I don't want to fix problem in my current case. I want to do something like avoid_edid_fuzzy_match=1, i want to fix it globally - Raspberry Pi select the best resolution and fps, no matter what is the pixel clock

[popcornmix]

I posted in #1046 the basic rules used for choosing the default resolution. I think the reason DMT51 is chosen over DMT82 is 51 is listed in the standard timings and 82 is not.
That is considered a preference by the monitor for those listed resolutions.

@popcornmix so can I do something to prevent this behavior?
I prefer this algorithm:

1. Get all available modes from edid
2. Select the ones with the biggest resolution
3. Select the one with the best framerate (fps)

[popcornmix]

That's not generally desired. Highest resolution is not necessarily best.
A monitor that is natively (i.e. has this many physical pixels) 1360x768 may support 1920x1080 but will provide a sharper image at its native resolution.

@popcornmix if I connect my Pi to the same monitor but HDMI-HDMI, Pi selects 1920x1080. But there are black borders, that can be disabled by disable_overscan=1.

[popcornmix]

Yes - DVI connection prefers DMT modes.
HDMI connection prefers CEA modes. 1600x1200 isn't a standard CEA mode.

@zervankoru I believe that your questions have been answered, can this issue be closed?

Yea
