Windows suggests my resolution be 1360x768. I have a LG TV that is capable of full 1080p, but when I switch the resolution to 1920x1080 it looks bad. It's blurry. I have an AMD Phenom II X4 and an ATI 4800 graphics card that I'm using the HDMI out. Can I get 1080p? What do I need to do differently?

Some models of TVs require the PC to be connected to a specific HDMI port, and the port labeled with the "PC" label.

What's the native resolution of your TV? Just because a TV accepts 1080p doesn't mean it can actually display it. Sounds like you've got an older TV that's not actually 1080p.

The TV is a few years old, but I purchased it as a "full 1080p" model. How do I find the "native resolution?"

What is the model number of your LG TV?

 

[jefejt]

It is an 47LG50.

 

[Zon2020]

Native resolution is 1920 x 1080p

Set your resolution to 1080p. In your TV's menu set the Aspect ratio to "Just Scan".

When I adjust the resolution to 1929x1080 it looks terrible that's the problem.

 

[Boke01]

But did you turn on "Just Scan"?

 

[Puwaha]

Ok... are you using an HDMI cable to connect the video card to the TV?


If you are using a VGA cable, then the TV will probably limit the resolution to be 1360x768. My parent's very expensive Bravia TV only accepts up to 1360x768 over VGA.

I'm using HDMI but just scan isn't an option. I can only choose 16:9 or 4:3. I see it as an option but I cannot select it.

I have an LG65LW6500. What picture setting do you have the TV on? Alot of the default picture modes look absolutely terrible. Did you try any of the others? Also, do you have the output set Full RGB in the Pixel Format mode?

When I did it in this order I was able to select "just scan". It looks better, but now it isn't using the full screen. It's in a slightly smaller window. It looked better in 720p, but I'd like to utilize 1080p to it's fullest if possible.

You need to adjust for overscan in you gpu's driver software.

Yep, Now that you have 1080p "Just Scan" working you need to turn off the underscan the AMD drivers do and you should be set.


Open the AMD Vision control center or Catalyst control center.


Click on "My Digital Flat-Panels" under that you will see "Scaling Options" Click on that and move the "Scaling Options" slider to 0% and you should be good to go.


Why AMD/ATI thinks its a good idea to underscan by default is beyond me.

Got it. Thanks everyone.
