1920x1080i 60hz vs 1920x1080 60i resolution output

[stabone24]

I have two Samsungs- one is Samsung-55" Class / 1080p / 120Hz / 3D LED-LCD HDTV-UN55D6420U that is outputting 1920x1080 60i when I hit the info button on the remote.

My other TV Samsung-46" Class / 1080p / 120Hz / LED-LCD HDTV-UN46D6000S is outputting 1920x1080i 60hz.

My question is which is better and how do I set the better one on the TV that needs it. I feel like the setting of 1920x1080i 60hz is a better picture..? Am I right?

Thanks,

Bill

LCD/LED/Plasma TVs output only one resolution, known as its native resolution, and you cannot change it. Both of those TVs are described as 1080p.

The info button shows you the resolution of the incoming signal. When the info shows 1080i, the TV will deinterlace it so it is 1080p and that is what it is displaying.

So they are the exact same thing even though it reads as different?

Yes, both are showing 1080i at 60 Hz as the incoming resolution which is a standard HD resolution.

It's just that one chose to put the 'i' next to the resolution and call out the 60 Hz frame rate separately and the other combined the 60 Hz and interlaced into a single '60i'. You see that sometimes with film where it is 24 frames per second (instead of 60) - sometimes it is written as 1080p/24 and sometimes as 1080/24p.

Ok, maybe I just need to buy a better HDMI cable to sharpen the picture up.

Unless you have a bad HDMI cable I doubt this will be the case. What is the source that is supplying the 1080i content? Many cable companies compress their signals which will cause artifacts in the picture. If you blu-ray's look good then I would blame the cable company and not your hdmi cable.

I have owned many different HDMI cables ranging from fairly expensive audioquest cables to monoprice cables and I have not seen any improvement or loss of quality with these cables that are 6 feet or less. If you have a long run then a lower gauge cable may help.

The source is Time Warner Cable in NYC. It's a 4' cable, not long range. The whole reason I curious about the resolution output difference on each TV was because the 1920x1080i 60hz looks better, but it apparently is the same thing as 1920x1080 60i which is looking slighty grainy and not as sharp. Could just be the signal on that line to that TV.

That could be the case but I have two other ideas.

1) An i signal is interlaced so the tv has to deinterlace the signal to produce its native resolution of 1080p. If these TV's are not identical models then the quality of the video chip could be different between the two sets.

2) One TV is larger than the other. In many cases the 46" TV will look better than the 55" at closer viewing distances. You should be sitting farther away from the 55 than the 46 so if you are viewing them at the normal viewing distance for the 46 the 55 will not look as sharp because the lines are farther apart than they are on the 46.

Oh and Time Warner is know if its heavily compressed signals. Can you get FIOS?

 

[stabone24]

No FIOS yet in my neighborhood.

I recently changed from Time Warner Cable because I wasn't happy with the picture quality. So I can appreciate your issue. It's probably not your TV but Time Warner.

Just a quick question, did you calibrate both these TV's?
