[gentoo-user] xorg.conf (HDMI vs DVI-D)

[James]

Hello,

We'll I've got a new samsung monitor 2333HD-1
that is verified 1920x1080.

Finally, I got it working on a dvi-d-2-dvi-d video cable
with no problems...(minimal xorg.conf) and ati-drivers.


OK, so I switch to a DVI-D<on video card> to HDMI
on the monitor and it comes in, but the bottom and sides
are missing. 

OK so I found this thread that I'm guessing is
on the mark:
http://www.phoronix.com/forums/showthread.php?t=23826

But, I'm a little bit 'chicken' with xorg.conf, not
to mention messing with the dot clock et al.......
<CLUCK  CLUCK  CLUCK>

Anyone want to venture a guess about the display settings,
suggested in the link? that I should use? A better way?

Here's the (example) math I use to use:
#       DisplaySize 426 266
# width  = (1680pix  / 100pix/in) x [25.4mm/in] =  427 --> 426
# hieght = (1050pix  / 100pix/in) x [25.4mm/in] =  267 --> 266


Here is what's working with the dvi-dvi cable:

Section "Monitor"
        Identifier   "aticonfig-Monitor[0]-0"
        Option      "VendorName" "ATI Proprietary Driver"
        Option      "ModelName" "Generic Autodetecting Monitor"
        Option      "DPMS" "true"
        HorizSync    30-81
        VertRefresh  56-75
EndSection

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        BusID       "PCI:2:0:0"
#       Option      "XAANoOffscreenPixmaps" "true"
EndSection

Section "Screen"
        Identifier "aticonfig-Screen[0]-0"
        Device     "aticonfig-Device[0]-0"
        Monitor    "aticonfig-Monitor[0]-0"
        DefaultDepth     24
        SubSection "Display"
                Viewport  0 0
                Depth     24
                Modes    "1920x1080" "1680x1050" "1280x1024" "1024x768"
        EndSubSection
EndSection

I guess this is the question to me:

Is the monitor doing overscan on HDMI?
or
Is the ATI driver doing underscan on HDMI based on the assumption that
the monitor will overscan?

Check if your monitor on-screen menu has overscan settings (or change
it to "PC Mode" or something, the manufacturers all have different
terminology). Otherwise if it has no settings you'll have to conitunue
messing with the ATI drivers instead.

I'd assume the monitor (HDMI input) is doing the overscan,
since HDMI is suppose to be 'smart'. 
That what the link suggested.

NO, it works find with a dvi-d 2 dvi-d cable. The computer is
always dvi-d (to either dvi-d cable 1 or hdmi cable 2)..
so how could ati-driver be doing the hdmi (embedded) protocol?

NO, the only  pc setting is when you use a standard 15 pin
VGA cable and no protocol to adjust scan or scan ratesss....


I'm guessing I stuck with xorg.conf machinations.....
(oh boy, here we go again......)

Ideas?

I just looked at the manual for this TV online and it looks like it
has "Just Scan" mode which could potentially show you the original
image by pressing the P.SIZE button on the remote control. So you
might want to try again to see if this option does what you need. :)

I don't have an answer to your actual question, but I can answer the above.

You have nothing to fear from fiddling with clock settings on a flat panel.
That only ever applied to CRT displays where running the horizontal frequency 
higher than the circuit was designed for would increase the HT voltage at the 
final anode - which often cracked the thin glass on the tube neck.

Flat panels do not have a concept of scan coil to drive, there is no HT 
transformer and there is no tube to have 28kV inside of. The owrst you can do 
is to get no picture.

Have you tried setting the INPUT NAME of the HDMI to "PC" using the
remote (on TV)?
My Samsung does the same, after I set my HDMI as "PC" everything is at
the right place.

Can you set overscan to 0% in the ATI Catalyst Control Center. Does that
make a difference?

THANKS, never tried that button. It does not permanently set though...

the default is 16:9 (which should work), 'wide fit', 
then 4:3, then 'just scan'.

'just scan' does the trick.
 It does not permanently set though...

What's the link to the manual...?
I never could find it.


TIA,

Can only do this on the PC selection which only works when
a standard 15 pin VGA cable is used...

Dunno know. 'ATI catalyst Control Center' will not
launch from KDE menu system....(strange)

Ideas on what to recompile?

ati-drivers? emerge -1 `qlist -I -C x11-drivers`

has already been ran several times today....

???
Can I lauch it (syntax) from the command line?
(as root?)

Accourding to the manual, it is possible to change the input source name.

I would advice the OP to try again what I suggested, I have a very
similar Samsung TV/Monitor, and using DVI and VGA works perfectly with
the computer, but I started using an HDMI cable, and the image would
distort, all borders would be missing, till I change the name of the
HDMI2 (the one I'm using) to "PC". Voila, everything to the right
place.

That's not written at the manual (neither yours, not the one for my
TV), I learned it using a forum for HTPC owners.

My 2333HD-1 only has one hdmi input, and the name cannot be changed.

I used hdmi on the video card and DVI-D on the monitor, and
the resolution is as it should be, with no over-scanning.


Thanks for the input.
