ATV digital lag stuttering on new tv

Question

ATV digital lag stuttering on new tv

I have had atv2 for about a year now using it on a toshiba 32 in HD flat screen with 720p with no problems.

I recently hooked it up to a new LG 42 in LCD with 1080p. You can see a definite lag or stutter in the video from time to time. It's like when someone makes a quick move on the screen it gets slowed down to a fram by fram look. Thats the only way I can explain it. Its very annoying. The tv works fine with DTV, and the DVD player through HDMI inputs. The lag only shows up with the ATV. Is this some kind of refresh rate problem? Or maybe the HDMI cable isn't fast enough for this tv? Maybe a wifi problem? I just can't imagine what would cause this. Any suggestions would be welcome.

BTW- I am using an Airport Exteme for my wireless router and the ATV is in the same spot it was when it was working fine with the older tv.

Apple TV

It happens on anything I watch on the ATV. Netflix, Apple Movies and TV Shows, Vimeo, Youtube.

Thanks for the link. I am familar with all of those issues. And as I said I had no problems at all with the older TV. I have DSL at about 10 Mps. The TV has a feature called Anti-Judder. If I turn the setting to high the stuttering (or juddering) increases. If I turn it off the stuttering is less but still there. Its definitely some sort of digital lad time issue. Its not buffering at all. No steaming issues. Thats what I'm thinking anyway.

Based on everything you are saying and wrote....

nothing changed except the TV

I'd have to say its the TV

You've already examined setting within AppleTV and since nothing else changed it has to be the TV unless the AppleTV went bad or have you hooked it back up to the old tv to check that already?

I would agree that in some way it has to be the TV. But the TV plays all other source content fine. So maybe its some sort of comaptibility issue with the ATV? I would think the ATV would work with all the new model TV's just fine. I was hoping there were some settings I could change to make them get along better. Some settings I could check or tweek on the ATV. I have not tried to hook up the ATV to the old set up again. Huge pain to do that now. I guess its possible the ATV just coincidentally went funny when I did the TV swap. But not probable. Murphys Law might be coming into play here. That would be my luck.

The TV User Manual is written for basic users. No technical troubleshooting or info at all. No help there.

I am going to try a "high speed" HDMI cable that can handle 240hz frame rates, 15 Gbps, and 1080p and higher just for giggles and grins. Try the weakest link in the chain first I guess. Though I dont have much faith that it will make any difference.

"high speed" cable made no difference. All other inputs work fine. TV and DVD are smooth.

Its got to be some sort of ATV digital conversion rate issue.

I would agree too if the same thing happened with all the inputs. But it only happens with the ATV. TV and DVD are smooth. Perhaps the tv is so HD it is showing imperfections in the ATV that the older tv didnt.

I'm in Vermont, USA. The unit is an ATV2 and I have the video output to Auto which has picked 720p to send to the tv.

Its related to your TV

OR

Your Apple TV is/has gone bad

OR

Set your ATV to 720 (not auto) and then remove power to the AppleTv and then wait 10 seconds and plug it back in and try again.
