So I have received a few PMs asking how I was able to achieve 1368 x 768 on the LC2600N. I decided to reinstall my video card driver and start from scratch so I could give step by step instructions with screen shots on how to get 1:1 mapping on the LC2600N.
You may remember, I had posted instructions awhile back on how to do this and it turns out they were wrong. I was going from memory before and when I was first trying to get 1:1 mapping set up, I tried all sorts of stuff and obviously got confused on which steps worked. The instructions below worked for me 10 minutes ago
Sorry about the bad instructions before. I will go back and edit the old instructions to point to this post.
Anyway, let's try this again...
First off, I'm connecting to the TV via DVI. I'm using an old Radeon AIW and the latest Catalyst Driver but as you'll soon see, that doesn't matter.
1. TV Set up
On the TV go to Menu>Setup>Input Signal and set it to 1366X768. Scroll down to Option and make sure Input Select says Digital PC (although, you wouldn't see anything if it didn't). Hit the Aspect button on the remote and make sure it says Dot by Dot.
2. PC Setup
First, you're going to have to install Powerstrip. But don't worry, it's really easy to do what you need and once you get the resolution set up, you can uninstall Powerstrip.DL Powerstrip from here
Once you have Powerstrip Installed (and the PC rebooted) copy the custom timing below to the clipboard:
Launch Powerstrip. A screen will pop up telling you to click OK so Powerstrip can save the default settings. Click OK.
Then a screen will pop up with the default settings listed (see screen shot below. Don't worry about my numbers listed there, I took the screen shot after I already got everything setup). Click OK.Screen shot 1
There should now be a Powerstrip Icon in the system tray. Right click it and select Display Profiles -> Configure. A screen should pop up that looks like the screen shot below:Screen shot 2
Click on the button that says Advanced timing options...
All you have to do now is hit the Paste from Clip Board button (circled in red in the screen shot below) and this will copy that custom timing above into Powerstrip.Screen shot 3
You will get a popup (see screen shot below) that says it has added the new resolution to the User-Defined list. Click OK.Screen Shot
Click OK. Click OK again. Powerstrip says you need to reboot so go ahead and do it.
After the reboot, open Powerstrip again. Click on Advanced timing options, click on the Custom resolutions button...Screen Shot
click on the User Defined radio button and select the 1368 X 768 resolution and then click the Add New Resolution button. You'll now get this popupScreen Shot
Click Restart to reboot.
After the reboot you should be able to select the resolution in your video card driver. You also may be able to select the resolution in the Windows Display Properties (right-click desktop -> Settings tab). On my PC running Win2k SP4, I did not see the new resolution in the Windows display properties. I could select it in the ATI Control Center but it would not stick after a reboot. It would default back to 1280 x 768. To fix this, I had to update my monitor driver using the steps under Update Monitor Driver below.
So, if you're able to select the new resolution under the Windows Display Properties or in the video card driver, do that, then do a Auto Sync on the TV. It should now look great. Now reboot. If the new resolution stays then you're done. If not, you'll have to update your monitor driver.Update Monitor Driver (may not be necessary)
Here's how I do it. Go into the Windows Device Manager, click on Monitor->Properties->Driver->Update Driver. Select the radio button that says, Display a list of the known drivers....etc. Click next and then select the radio button that says, Show all hardware for this device class and find the Sony GDM-W900. Click Finish or OK or whatever it says.
After you update the monitor driver, right click on the desktop, go to the Settings tab and then move the slider until you get 1368 x 768 and click Ok.
Finally, in the TV menu again, do an Auto Sync. You should be good to go now. The timings I used (that bunch of numbers above I had you copy to your clip board) worked for me. If the Auto Sync doesn't give you razor sharp and stable text, your TV may not like those timings. There are a bunch of 1368 x 768 timings out there on this site and on the forums on the Powerstrip site. Try as many as you can until it looks good.
