Setting up video for a HUGE TV

[soccerdad]

OK, my sister went insane and got me a 75" Samsung TV. I am finally able to say that it is too big for the room. You see everything. So I want to optimize the video settings coming from my HTPC. I use AMD stuff and have a gigabyte motherboard with HD 4250 graphics on board. I need your help determining the best settings for this monster. In the past with smaller screens, I just set it the max resolution and then used the underscanning to fit it to the screen edges.

What is the "correct" way to set it up to get the most out of system. (besides sending to you ) I have the standard AMD control panel to work with.

Usually,TV's and monitors look best at their native resolutions and the highest
refresh rate they can handle.
You may have to enable HDTV resolutions in catalyst control center.
Under "My digital flat panels"-HDTV support.

Don't use the underscanning setting to fit the image to the edge of the screen. This will distort your picture.

Instead, go through the "Setup your display" wizard. When it asks you what kind of display you're using, choose "TV". Do not choose "Flat panel" or any of the other options. Choosing "TV" will eliminate the overscan created by Media Center. Then, go into your TV's settings menu, and change the display to "Screen Fit". That's what Samsung calls their 1:1 pixel mapping.

Of course, also choose the native resolution of the TV, which is probably 1080p (1920x1080 @ 59Hz).

^ To add to barnabas' comments, also set the TV to 'Screen Fit' to get 1:1 pixel mapping.

For the ATI, here's my settings:

YCbCr 4:4:4 Pixel Format
Use Video Player Settings
Dynamic Range: Full 0-255 (this works with YCbCr and your TV's grayed out HDMI black level)
Vector Adaptive Deinterlacing
Pulldown detection (debatable whether to let your TV do this or the ATI - conflicting info around for either method)

Everything else on the ATI disabled / off

Then set your black level and your contrast by eye on the TV using a calibration disc / downloaded calibration slides.

Make sure nominal range is set to '2' in the registry (default).

On my Samsung 60", you also have to name the HDMI port as anything that is not PC or DVIPC. When naming it PC or DVIPC, it seems to disable all video settings and also seems to add a slight blur to the picture.

[STC]

^ Yes correct. Those modes decrease latency for gaming at the expense of some processing.
My HTPC TV HDMI port has no label.

Great suggestions. I will give them a try.
This is an awesome piece of hardware.

Didn't I say that already?

[STC]

Oh yes. I didn't read your post fully (for fear of hot gas escaping!). Apologies.

so I went to regedit to check this out but I don't have ehPresenter.dll under debug, only ehReceiver. I have never messed much with registry so I have no idea how to create it and set it to "nominal range"=dword:2 and "nominal range"=dword:1

I have my ATI settings the way you have yours listed, but I still get some flicker on certain channels. It's not too bad, but noticeable.

I have been playing with the settings again. I think everything is set correctly but now I have about 1.5 inches on each side of the picture black and 1.25" top and bottom black. I have it set to screen fit. I have the amd vision engine control center setting to 1920x1080. Under desktop management it says 1080p.
I have onboard HD4250 graphics. I do not have CCC and don't know how to get it. I do not see anywhere to set interlacing etc. I turned off all overscanning. I tried with and without "enable gpu scaling" checked with the same results. I chose TV in WMC setup. Kind of at a loss what to do. Setting the TV to 16:9 fills the entire screen and looks great. Not sure if this is a bad way to do it or not.
How do I get CCC? (updating does not give it to me)

YCbCr 4:4:4 Pixel Format YES
Use Video Player Settings YES
Dynamic Range: Full 0-255 (this works with YCbCr and your TV's grayed out HDMI black level) I only see Enable dynamic contrast-now ON
Vector Adaptive Deinterlacing -YES
Pulldown detection (debatable whether to let your TV do this or the ATI - conflicting info around for either method)- ON

You can double tap the CCC icon in systray.

When open check overscan is set to 0 in My Digital Flat Panels / Scaling.

[soccerdad]

Is "amd vision engine control center " now the same as Catalyst Control Center? It seems like it is.

I will check overscan again, I was sure it is 0 or off but I will check again.

[soccerdad]

Well the overscan was set to an underscan. So I set it to 0 and now it is correct with screen fit. Thanks, I was sure this was already set to 0.
