Samsung 171v and gddccontrol

There's no monitor file for the Samsung 171v (SAM0063.xml)l in ddccontrol-db, but there is a listing for the Samsung 173s in the (SAM00A3.xml) file which is extremely similar.

So we'll copy that and put it into /usr/share/ddccontrol-db/monitor/SAM0063.xml.


There's no speakers so we'll take the 62 entry out of the caps add line.

<?xml version="1.0"?>
<!--- Samsung SyncMaster 173s SAM00A3 has some partial DDC/CI support (no caps) -->
<monitor name="Samsung Syncmaster 171v SAM0063 copied from 173s SAM00A3" init="standard">

<caps add="(vcp(10 12 16 18 1a 20 30 d0 d2))"/>  

 <control id="fine"       address="0xd0"/>
 <control id="coarse"     address="0xd2"/>
 <!--- Control 0xdc: +/116/255   [???] -->
 <!--- Control 0xdd: +/116/255   [???] -->
 <!--- Control 0xde: +/115/255   [???] -->
 <!--- Control 0xe4: +/145/255   [???] -->

 <!--- Control 0xe8: +/131/255   [???] -->
 <!--- Control 0xea: +/0/0   [???] -->
 <include file="VESA"/>
</monitor>

So if you're curious, here's the full ddccontrol -c -p -d output:

sudo ddccontrol -c -d -p

=============================== WARNING ===============================
There is no support for your monitor in the database, but ddccontrol is
using a basic generic profile. Many controls will not be supported, and
some controls may not work as expected.
Please update ddccontrol-db, or, if you are already using the latest
version, please send the output of the following command to
ddccontrol-users@lists.sourceforge.net:

LANG= LC_ALL= ddccontrol -p -c -d

Thank you.
