[gentoo-user] display adjustments

[James]

Hello,

I have a one new gentoo sytems installed that works good with a 20"
Sceptre LCD monitor.

However, when I move the hdmi connector to a 32" vizio hdtv/display,
the display is too large for the physical screen. This happens
before I 'startx' and after kde/X starts up.

I tried using "DisplaySize" but that did not work.

Any ideas? What baffles me is the display is too big
in console mode too?

Is there not some sort of setting on the TV to adjust it? Usually there
is some automatic adjustment, or you can change the height/width of the
picture.

Hello David,

Well there definately is on the old CRT analog monitors, but, this one
does not have such dials. It has a software interface, but I have not
seen anything inside of it. I'll take another look, as there are many
many buttons on the remote.

Another friend (not on the gentoo list) suggested I look into settings
on the ATI card (via aticonfig or such) but this is another research
project.

thanks for the suggestion.


James

what is the actual native resolution of the 32" hdtv?  I would guess not
as good as the 20" LCD, which is probably 1680x1200.  HDTV can support
up to 1920x1440 I think, but here in Aust. we only get 1600x1080 or
something stupid like that.  Unless it's a high end HDTV, you may not be
getting 1920x1440.  Try changing the resolution to 1024x768, then work
your way up.  Also try and get the frequencies of the tv, and set those
explicitly.

I don't know much about HDMI - is it just analog video (ie. component)
with HD capability and DRM?

If so, you may want to look for some TV settings in your xorg.conf like
overscan.  I've found that depending on the card / tv combo I'm using,
the picture can be too big, too small, too far to the left, etc.

not sure what that is.

yeah, that sounds like either the resolution is too big for the tv, or
the video signal just needs a bit of tweaking!

HDTV is 1280x720 or 1920x1080, either progressive (eg 720p or 1080p) or
interlaced (1080i)
If his HDTV only does 1280x720 (very possible, most 32in panels I saw
when I worked for an electronics store up until this summer were usually
something like 1366x768 native res or such) then it is very possible his
20in LCD supports a higher resolution, like 1680x1050 (widescreen) or
1600x1200 (4:3). Then again, I live in the UK.

HDMI is essentially DVI + 5.1 Surround sound + DRM. It's a digital
connection, not analogue. Component connections (Pb/Pr/Y) are analogue
HD connections.
