I'm guessing that the Samsung 1080i HDTV you're talking about is a CRT cuz there are no 1080i LCD or plasma HDTVs that I'm aware of. One thing to know about those is that they aren't really 1080i. A huge amount of pixels are missing, most of them being in the neighborhood of 853X1080 interlaced. What it really works out to is around 1 million pixels interlaced. Or in other words it's kinda 720i although they don't call them that. I don't use it anymore but still have a so-called 1080i CRT made by Sony (XBR970). I was pretty pissed off when I discovered that the resolution was 853X1080 rather than 1920X1080. Then after doing some further research I discovered that there are no true 1080i CRTs on the consumer market. Almost all of them are the same resolution as my Sony. The highest they ever got for the consumer market was a few Sony models that were 1440X1080 interlaced (XBR960 being one of them). Those used some special and unusual kind of tube (Called the Super Fine Pitch) that was expensive as hell. I've never understood why there are CRT monitors that can have high progressive resolutions but when it comes to CRT televisions they can't do 720p or even 1080i correctly but that's the way it is.
i think you're confusing 1080i with 1080p. the "i" in 1080i stands for interlaced, so it will never have the resolution of 1080p. if it did, why would it be called 1080i? the whole point of interlacing is to give the illusion of double the information, by updating only half the display each cycle.
hence, no 1080i display will have the same resolution (at each cycle) as a 1080p display, they are not the same thing.
Lol, what are you talking about? If I were confusing them I wouldn't have went out of my way to mention interlaced and/or progressive so many times (I think that line you put in bold is like the only one I didn't bother specifying interlaced in. Didn't think I needed to type it again because I had just said I was talking about a 1080i television. But nope, I should know by now to never overestimate my audience, lol). When one gets a 1080i HDTV they expect it to be 1920 X 1080 interlaced. That's what the 1080i specification is. I never expected 1080p out of a supposedly 1080i HDTV, lol. But did I expect 1080i out of an alleged 1080i HDTV? Absolutely. Instead what I got was 853 X 1080 interlaced which is nowhere near as sharp as 1920 X 1080 interlaced, what 1080i is suppose to be.
ok, so 1920x1080 is an aspect ratio of 16:9, but your display is 853x1080 so are you really telling me it has an aspect of glorious 8:9? that means its height is longer than its width? is it a portrait monitor?
you're also telling me that 1080i TVs aren't really 1080i, which makes one wonder whether 1080i TVs really exists or if it's a myth.
also interlacing is always horizontal, so if 853 pixels is the number of horizontal lines, that would mean there's a discrepancy of 1 line between each frame (because 853 is an odd number), which sounds odd from a technical perspective.
do you now see why there's confusion here? after 15 minutes of googling i can't find an authoritative source that tells me what exactly is 853x1080 and how it differs from 1080i. all i'm seeing here are old (2011 or earlier) forum topics on displays that allegedly display this resolution.
Simple, rectangular pixels.
