I've got an Asrock 330 hooked up to a Samsung 46" LCD TV.
They are connected via HDMI.

I have set the TV to "Just Scan" and the picture looks perfect.

However, if I reboot the Asrock, the TV switches back to 16:9 mode and I have to switch it back to "Just scan".

Has anyone with a Samsung TV had similar behaviour?

Mine stays on Just Scan... I have a 40 though. Lnt4061f.

Maybe goto the setup of the TV and change it there (instead of cycling through them). See if that makes a difference.

Had the same issue with my display reverting back after my receiver is turned off or the HTPC starts.

The fix is to hold the menu button down for 10secs untill Dynamic is displayed - It should now remember to stay on "Just Scan"

i have the same trouble on my samsung, works from the windows box fine as second display, maybe it gets confused due to the bootscreen? ill give AzzX suggestion a try, also i dont really get it, dynamic is usual a viewmode... we will see

Hi!

I have the same problem with my Samsung LE40A866 TV.
Shop-mode is not the issue for me, I have set my TV to "home-mode".

Whenever I reboot (my Asrock Ion 330 with Ubuntu 9.04 and XBMC) it changes back to 16:9 everytime. All other settings are saved accept the "just scan" setting.

Did you find a solution for the problem?

I have the same issue...
Running XBMC on Ubuntu, ION 330

I had the same problem on my Samsung TV and after spending hours searching all kinds of forums I finally found a solution (can't remember where I found the answer though):

1. Connect HTPC to HDMI2 on TV
2. Rename HDMI2 in the TV setup menu to "PC"

After I've done this, only "4:3" and "16:9" aspects are available for HDMI2, but "16:9" behaves like "just scan" and it survives a reboot of the HTPC.

1. Connect HTPC to HDMI2 on TV
2. Rename HDMI2 in the TV setup menu to "PC"

Lucky you! this didnt work for me.. think Ive got a series 6. Ill keep searching for an answer and in the meantime use a macro on my mx-810 to control it.

[iGudi]

Didn't work for me either...

Would be nice if you could disable the different sizes - as I ONLY use "Just scan".
Also the different sources that you dont use, annoying that you have to jump over those you dont use.

It's because you use your xorg.conf is set to negotiate the resolution with the tv through the edid.

Turn of ed-id and set the resolution manually, that wil fix it. The tv will always stay on just scan.

This is the xorg.conf i use:

but ubuntu Januty is reporting mode is not supported. Is this something to do with the resolutions I've selected. Please find xorg.conf below. Any help would be great thanks.

I get this problem with a 2007 Samsung 40" 720p LCD HDTV LN-T4053H connected to a Raspberry Pi with Kodi 17.6.

Kodi 16 was able to set the resolution correctly without my having to go into the TV's settings and setting "Just Scan".

Also, do these Samsung TVs have an internal battery that needs replacing? My TV doesn't remember any settings (except it does remember TV channels), and sometimes it loses the "Just Scan" setting even while the TV is on!
