Note: writing this in the sort of annoying narrative form. Skip to the end if you just want the good part.
I was pretty disapointed when I saw that this tv only supported 1280x1024 as its max resolution (it's in the manual somewhere..certainly not on the box or anywhere you'd see in the store) but had settled for running it in 1280x768 to keep a sane aspect ratio.
After reading Archonius
's near-success I decided to give it a try, as I had never even gotten the pillarboxed image.
So I gave it a shot, got the same results. Even tried dropping it to 1080i which was a little better in that it wasn't pillarboxed, but it was horribly off-set and worse than the hdmi overscan.
About this time I was going to write a frustrated email to Insignia just to see if they'd help, but before hitting send I had one last idea.. Try some different preset timings I had remembered hearing about. It worked. I now have full 1080p with no overscan or other issue that I've noticed.
Here's the quick howto:Note:
Messing with video timing is a scary thing. Or so I always read. The only issue I've ever had was making a CRT whine, but still I take no responsibility for what happens with this.
I should also note that I did this with an Nvidia 7300LE. Supposidly ATI cards use different timings, but I don't think its an issue if you do it through the preset.
Enough rambling. Heres the step by step:
Install the video tweaking program powerstrip. I tried to link but as this is my first post the forum rejected it, just google for 'powerstrip' and its the first link.
Right click on the tray icon and go to Display Profiles -> Configure.
There should be the name of your video card on the top of this new window. If you use dual monitors, you'll want to hit the down arrow on the far right of it to make sure its on the right one.
You can tell by the resolution, and it will say PTS108B on the left side.
Change the resolution slider to 1920x1080 and change the refresh rate drop box to "Custom Timing" and click Advanced Timing Options.
From there, click the Custom Resolutions button.
Heres where you finally get to pick presets. I screenshotted what mine looked like for comparison.
You'll want to check the "Aspect ratio: 16:9" radio button. This isn't needed but makes the list a LOT easier to deal with.
Now scroll down the list until you see 1920x1080p 60hz (EIA/CEA-861B)
and select it and click the "Add new resolution" button. Watch your tv's image change.
You might want to go into the video menu on your monitor and go to the vga section and click 'auto adjust' now just to make sure.
Let me know if you can't get this to work and I'll try to take more screenshots or maybe even screencast it if you'd like.
