hd-pvr overscan

[AC-T660]

This seems like a HP-PVR issue and not Sage, but I’m wondering if anyone else has had this issue and if so if they have figured it out.

I’m using a HD-PVR with a Dish Network VIP 211 on a Samsung LN52A550 tv. Everything I watch or record over this tuner is zoomed in too far and is cutting the screen off all around. I would guess it’s about 5% larger than my screen. This is only on the HD-PVR though, my HVR-1600 ota channels are fine.

I’ve looked at the overscan settings in Sage, but it seems to be for the UI, not the video. I also tried adjusting the aspect ratio, but that just caused my zoomed in image to be smaller, it didn’t show the missing edges.

I tried watching through ArcSoft’s TME and I get the same overscan. I can’t find a way to adjust it on the Dish box, Sage, or TME. Am I missing something, or do I just have to live with some of the screen cropped off?

I’ve searched through this forum and others and have seen similar issues (sometimes zoomed out instead of in), but haven’t found a solution. The guy in the link below seems to have had the same problem but it appears to have fixed on its own.

Anyway, if anyone has any ideas let me know. Thanks in advance.

If you are using an NVidia video card, the NVidia control panel has an overscan adjustment. It actually changes the logical resolution of the HDTV, so it applies to both SageTV UI as well as the computer desktop and other applications.

Thanks Tim, but that's not the issue. I do have a Nvidia card, but windows is already sized right to fit the tv borders. It's only the HD-PVR signal that seems to be larger than 1920x1080.

Bummer, nobody's got an answer huh? Let me ask this then, is anybody else seeing this problem (but you just don't have a solution for it)? In my case it cuts off the screen all the way around, so you lose the top or bottom banners if there are any. I don't know if it's caused by the Dish receiver, my PC, or the HD-PVR. When I get a chance I'll do some trial and error like hook it up to my laptop or hook in different video sourses.

I'm guessing this IS an issue with the NVidia card running at a non-standard resolution. If you are only using this thing for sage, you SHOULD run it at full 1920x1080, and let it overscan. This will allow the 1080i recordings to play back 1:1 pixel mapped to your set, and avoid any sort of scaling requirement.

I have a VIP-211 as well and I think I can solve your problem. The VIP-211 has its own scaling options. Press the Page UP button and it will cycle through the HD scaling options. I believe that Page DOWN will do the same from the RF output.

Are you saying that I my PC should be running at the "native" resolution even though part of the screen is off the sides?

Then adjust the overscan in Sage only via the options?

Currently I have the screen adjusted with the NVIDIA settings for desktop resize. I think its something like 1822x1012 or something.

I assume that you are talking to me.

What I am saying is that the VIP-211k has its own scaling (stretching) options for its video outputs. Mine was messed up and I had to read the manual to figure out how to fix it.

Yep, that was it. Thanks a million fidget!

I'm having this issue on only one of my two HD-PVRs. It is clearly recording with some overscan/cropped setting and is not a UI or video card setting. If it were than both of my HD-PVRs would have the same issue.

I'd check the set-top-box settings to be sure it's locked in to the same resolution/settings as the other set-top-box, then check the HD-PVR settings, maybe do a sample recording in Total Media Extreme 2. Once you have it working properly in TME2, everything should smooth out in Sage.

It sounds like your set-top-box is in some form of zoom mode or strange aspect ratio.
