1080 Resolution Issues

[LC_Sulla]

Hi All! A long story, but: I have a Samsung DLP TV (720 resolution). I've had it about 6 years, great TV.

Since buying that TV, I've gotten a Blue Ray player and subscribed to digital cable with HD package (Metrocast). I've been wanting to upgrade to a 1080 HDTV for sometime, especially after seeing the picture quality of the demo units at Best Buy.

Several months ago, a friend bought a 1080 HDTV and hooked it up, he has satellite TV service with a few HD channels. After hooking it up, he reported issues. Hardto explain issues, but he thinks he sees ghosting, after images, aliasing (with lots of lines), and some motion issues. He was considering returning the TV because he could not figure out the root cause of the issue, and this is a smart guy.

Well, I went ahead an bought a new Samsung LED TV (1080). Hooked up the Metrocast cable box and the Blue Ray player via HDMI. I even went and purchased new HDMI cables.

Initially, I noticed some motion issues as well. Turning off the "Edge Enhancement" in the TV menu helped some, but it's still there.

With TV programming, some stations seem to exhibit motion issues to varying degrees, while the UHD channel is actually visually jerky.

With TV programs recorded on the Metrocast DVR, whenver there is a quick motion, I guess you would call it, motion blur, thought it doesn't exactly qualify as that, occurs.

So far, Blue Ray movies are awesome. I haven't notice the same edge or motion effects.

At this point, I was just wondering if anyone else has had issue with trying to watch true 1080 HDTV?

Also, when I switch channels, the TV displays the resolution and frequency (like 1920X1080 @ 60Hz). When I switch between HD channels, the resolution display changes. Makes me think that not all HD channes are being sent at the same resolution.

What's going on with the rest of you in the 1080 HDTV world?

thanks!

What you get from Satellite and Cable is compressed and is not "true HD". It takes a lot of bandwidth(approx. 40MB/s) to get a true HD picture. The channels on satellite and cable are compressed down to about 6-8MB/s while OTA (over the air) is approx. 14MB/s. The blur and jerkeyness is a result of the compression. Also there are yet to be any 1080P channels, whether it be from satellite, cable or OTA. The HD channels available now would be in either 720P or 1080i. If you're able to, try to pick up some OTA channels with an antenna. You will see a big difference between satellite/cable vs. OTA but not nearly as big vs. BluRay.

I know DirecTV and Dish offer OnDemand movies in 1080p. I would imagine FiOS could offer 1080p as well.

Speaking strictly of DirecTV as I don't have much experience with Dish nor FiOS. Yes, there is 1080P content, but there are no 1080p channels. In order to view 1080p content it must already be present on the DVR whether you download it via OnDemand or its one of the few monthly pushes via satellite.

(like 1920X1080 @ 60Hz).

I keep getting this also and I have yet to figure out why it's refreshing @ 60 Hz instead of 120Hz. (Yes it is a 120 Hz TV)

The TV is displaying the refresh of the source.

The TV is displaying the refresh of the source.

Exactly. If the signal is 60HZ, the display is 60HZ. Some TV's can double the HZ by simply refreshing twice for every 'screen' in the signal, but it won't noticebly effect motion blur.

NOBODY broadcasts in 120 yet that I know of.

Where the difference comes in, is that at 120HZ the TV displays each 'frame' 5 times at a 24 fps. A 60HZ TV has to manipulate the frames and you can get graininess with extremely fast moving or well defined/high contrast objects, such as letters on a 'ticker' or marquis.

I highly doubt the problem has anything to do with the HZ, unless you have a super keen eye. I have a 60 HZ Sony Bravia and neglegible motion blur.

Here's a Samsung owner having similar sounding issues... Do you have 'Motion Plus'? Try turning it off. They also suggest setting your "judder" setting between 3 and 5. Good luck!

My SAMSUNG has "auto-motion plus."

If you are watchin true HD from a Blue Ray (TM) player, you can turn auto-motion plus on or off, i.e. it will not cause the video to skip/lag/jump/whatever. What it will do, in this case, is (1) when it is off, the video will look like what you are used to when watching a movie, (2) when on, the characacters in the foreground are so sharp and clear, they don't appear to be part of the background, and it creates this weird look.

You can play around with the settings, and try to find a balance.

At the end of the day, it appears to be a matter of preference. I like seeing the detail (bugs in the bark, if you willl).

Ther's a bit more to it than that. 120Hz TV's not only display twice as many frames per second, but they have internal image processors that actually simulate the "missing" frames. The computers in 120 Hz TVs take each frame and compare it to the frame after it, then creates the in-between image --kinda like how they morphing images to turn one person into another (or into an animal), only these images are much more similar-- and it does this for every frame, 60 times a second to create more fluid movement on the screen. So because of all the image processing, the signal is 60 Hz, but the display is 120 Hz.
