Windows 7: Auto detection/adjustment of the HDTV

Windows 7 Ultimate x64
Auto detection/adjustment of the HDTV

Hello guys, first of all my english is broken please dont mind^^

Im having a big problem with my Samsung LA32A550P1F which I use it to connect my PC (HDMI>mini HDMI)

Actually its no problem since I builded a new PC system running Window 7 x64 Ult.

My GPU is GTX 480

And I exchanged a new GPU card today and still having the same problem.

The TV keep auto detection/adjustment of the TV (which make the screen go on and off, and keep flashing) Window7 are still running fine and having music output (well Im listening MP3 hehe...)

I did try disbanding audio from the display card, update driver, MB bios etc. and all is useless~ the problem keep on and on.

I saw some guys are having the same problem as me and seems can not be solved?

Can anyone help me please?

I dont have another mon which give me a try on DVI, but Im sure its not my display card problem now~

Some people said that disable TMM in Task Scheduler could help~ but I cant find TMM in there even I follow the step or using regedit.

Thank you so much for helping^^

Welcome to SevenForums. First off I hope this is your TV Samsung Full HD LCD TV 550 Series 32" - LA32A550P1F - LCD TV - televisions | SAMSUNG

Does it show up in your device manager? Would you post a snip of your device manager>expand the monitor section.

Also please go to control panel> Nvidia control panel>click on change resolution>does it show both your monitor and TV in their? It should have a list of what displays are attached to your PC.

If so it should say Select the display you would like the to change>select the TV
You should now be able to see connector drop down menu, and it should show how it is hooked up to your graphics card HDMI, if not use the drop down menu and select HDMI>under the tab Refresh rate, it should be set at 60hz> under color depth tab>select highest 32bit> In the resolution box you should see a list of resolutions available.

Take another snip of Nvidia change resolution in Nvidia control panel so we can see what it looks like.

Here's a tutorial on how to post these snips I've requested A Preferred Method of Uploading/Posting Screen Shots

Once we have this information we'll have a better idea on how to proceed.

In the first link that has your TV in it, their are tabs on the side
1. Features
2. Tech specs
3. Learning resources
4. Support>under this tab you'll find quick guides and other support PDF's on your TV. You will also find contact us and other manuals plus firmware updates. You should really familiarize yourself with this information.

Once we have the requested information and you have read through the available material or even tried contacting Samsung for support on your issue.
We'll have more information to go on and work with to try and figure out a solution to this problem if one is possible
Thanks. Fabe
