Resolution issues on 32 inch HDTV

[mr_pablo]

I have my Pi hooked up to my HDTV (1080p) and the text on Debian "Squeeze" looks fuzzy (or blocky, either way it isn't crisp lol!)

I looked in the screen settings but it seems to already be rendering 1920 x 1080.

Is anyone else getting this? Is there a fix?

(will try and post a photo of it later)

I'd try config_hdmi_boost from here:

I will give that a go, but to me it looks like that fix is for signal issues, which isn't what I'm getting.

Sorry if I didn't explain too well. The signal is fine, its just that the resolution looks pixelated i.e. its not the correct resolution for 1080p.

Will try the fix non-the-less and report back

What does your TV report the input signal as?

Have you remembered to put:

disable_overscan=1

in your config.txt file ?

Without this your monitor may be interpolating pixels to render the slightly smaller image.

I will try the overscan option.

I looked in the resolution settings in Debian and the only options are something like 1550x800 (something like that, basically, not 1920x1080) and auto.

Can this also be fixed via the config.txt?

It's useful to bookmark http://elinux.org/RPi_config.txt so you always have a reference.

Remember there are two commands for showing supported modes on your monitor:

/opt/vc/bin/tvservice -m DMT
/opt/vc/bin/tvservice -m CEA

One of them should show as the "native" mode (I presume this is what it defaults to if there is no hdmi_group / hdmi_mode settings in config.txt)
