Windows 7 Mode Not Supported Error on LN-T4061F LCD TV

by DeathNACan - 8/29/09 4:09 PM

I have an ATI HD4670 video adapter I am using with a Samsung 40 Inch LCD LN-T4061F TV. The TV is attached to the video adapter via a VGA cable. Installed on the computer are Windows XP Professional 64 Bit and Windows Vista Ultimate 64 Bit operating systems. I can set the resolution to 1920x1080 with no problem under both OS's. The problem is that I can only go to 1600x1200 under Windows 7 Ultimate 64 Bit. When I try setting the resolution to 1920x1080 I get a 'Mode not supported' error on the monitor. I have installed several different driver version with no success. I have used driver cleaners to remove drivers and installed drivers and still had no luck. I suspect that the problem is with the Windows 7 handles EDID. Can you help.

DeathNACan,

It's likely that working drivers may still be under development. I don't have a solution, except to make sure that any overscan from the video card is turned to 0%.

Problem Solved!

I have an HIS ATI Radeo 4670 512MB PCIe Adapter and am running Windows 7 Ultimate Edition 64 Bit Version 7600.

Here is what I did to fix it. After trying at least 20 different drivers from ATI's site, I finally ended up going to HIS site.

http://www.hisdigital.com/un/download.shtml

I downloaded the driver with this description:

..................................................................................................
ATI Catalyst: (ref. no: 0812)
Platform: Windows Vista (32bit/64bit)
VISTA Driver Verison: Vista_8.523-080808a-068036C-ATI with WHQL Note: Users must have Microsoft's .NET Version 1.1 Framework prior to installing the ATI driver/Catalyst Control Centre(CCC) components

..................................................................................................

The file name is:

Vista_8.523-080808a-068036C-ATI.zip

This is the Vista driver for an ATI 4670 512 mb PCIe adapter.

Uncompress the file.

1. Boot into Safe Mode.

2. Execute the following from a command prompt to turn on the Windows Installer Service:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"
net start msiserver

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Network\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"
net start msiserver

3. Execute the following from a command prompt to isable Driver Signing:

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

4. Open the Device Manager.

5. Left Click and expand "Display adapters".

6. Right Click on the Display Adapter. Example: (ATI Radeon HD 4670)

7. Left Click Update Driver Software.

8. Left Click "Browse my computer for driver software"

9. Left Click "Let me pick from a list of device drivers on my computer".

10. When the window with the prompt "Select the device driver you want to install for this hardware." comes up, uncheck "Show compatible hardware".

11. Left Click "Have Disk".

12. Browse to the directory: "C:\Drivers\ATI\Support\Vista_8.523-080808a-068036C-ATI\Packages\Drivers\Display\LH6A_INF" and click on the inf file "CH_68036.inf"

(That's where I put the uncompressed driver files.)

13. Select your adapter (if necessary).

14. Follow prompts and reboot.

You should now be able to select 1920 x 1080 using your VGA cable.
