Hyundau Q321 Modelines for Ubuntu based XBMC


Active Member
Mods, please move if this is the wrong forum

I (still) have my Hyundai Q321 (remember those :D)

I'm trying to work out all the available modelines for putting into my xorg.conf under ubuntu for an xbmc system. I know it supports 60hz straight away but a lot of people reported being able to run it at 50hz. Anyone out there who did that can you give me your modeline or, for the non linux guys, can you give me the frequencies etc you used to run your panel.

Thanks for any help you can offer.



UPDATE: 20/01/2010
Extracted powerstrip and modelines for 50 and 60hz are now in the posting linked here http://www.avforums.com/forums/lcd-led-lcd-televisions/1177274-hyundau-q321-modelines-ubuntu-based-xbmc.html#post11336171 NB 50hz modeline is not working as expected, YET!

lots of visits but no one biting :hiya:

Interestingly this posting now seems to pop up first on google looking for modelines for this set.

Well, starting with the usual caveat that neither I or av forums are resposible if your pc tv or anything else spontaniously combusts or transmutes into a bowl of petunias I'll start off the party with my present info

Based on ubuntu karmic

#Modeline "[email protected]" 67.57 1360 1392 1648 1680 768 781 788 804

60Hz works
Modeline "[email protected]" 84.50 1360 1392 1712 1744 768 783 791 807

75Hz works but bounces resolution down to 1280 by something
Modeline "1360x768_75.00" 108.75 1360 1440 1584 1808 768 769 772 802

Now come on, dont be shy!!!

And one last time,

a quick update:

I extracted this from the monster 280+ posting thread:

Section "Monitor"
Identifier "Vvuon Q321"
Option "DPMS"
HorizSync 31-83
VertRefresh 56-85
Mode "1360x768" # vfreq 59.999Hz, hfreq 49.019kHz
DotClock 86.960000
HTimings 1360 1480 1528 1774
VTimings 768 778 783 817
Flags "-HSync" "-VSync"
Mode "1280x768" # vfreq 59.833Hz, hfreq 47.986kHz
DotClock 81.000000
HTimings 1280 1328 1440 1688
VTimings 768 769 772 802
Flags "+HSync" "+VSync"


(Seems to work OK)
Modeline "1360x768" 87.136 1360 1376 1488 1696 768 771 777 795 + hsync + Vsync


(Not yet tested) I believe will only work once 60hz has "activated" the screen
Modeline "1360x768 @ 50" 67.86 1360 1392 1648 1680 768 784 791 807 + hsync + Vsync


(This works but messes up the resolution)
Modeline "1360x768 @ 75" 111.93 1360 1392 1816 1848 768 782 792 807 + hsync + Vsync

And on that echoey, lonely note I'll leave this here for the night :hiya:

Hi all

I didnt originally intend this to be a one man show :D (thanks to 16bynine for the messages by the way, I appreciate the message even though you dont have a Q321 any more :smashin:)

Anyhoo I booted my revo into windows 7 and loaded powerstrip. The timings / modeline for 1360x768 @ 60 are as follows:

PowerStrip timing parameters:

Generic timing details for 1360x768:
HFP=120 HSW=48 HBP=246 kHz=49 VFP=10 VSW=5 VBP=34 Hz=60

VESA detailed timing:
PClk=87.00 H.Active=1360 H.Blank=414 H.Offset=104 HSW=48 V.Active=768 V.Blank=49 V.Offset=10 VSW=5

Linux modeline parameters:
"1360x768" 87.000 1360 1480 1528 1774 768 778 783 817 +hsync +vsync

I then tweaked the refresh back to 49.97 and got 720p 50 come up

PowerStrip timing parameters:

Generic timing details for 1360x768:
HFP=120 HSW=48 HBP=246 kHz=41 VFP=10 VSW=5 VBP=34 Hz=50

VESA detailed timing:
PClk=72433.00 H.Active=1360 H.Blank=414 H.Offset=104 HSW=48 V.Active=768 V.Blank=49 V.Offset=10 VSW=5

Linux modeline parameters:
"1360x768" 72.433 1360 1480 1528 1774 768 778 783 817 +hsync +vsync

I then edited my /etc/X11/xorg.conf and added in these modelines and some other dark magic and with a little tweaking in the system and video options I can get XBMC to switch between 1360x768 and 720p BUT! its switching in 720p @ 60Hz :mad:

The adventure continues....

...and it concludes

Yup, you can indeed get 50hz ... in powerstrip but its unstable in playback and in a modeline even more so. It may be possible but its not worth the work as it just causes more issues. I'll stick with 60 as I'm working toward migrating the 321 to the bedroom and getting a new 42+ panel.
