how can a LCDTV with native resolution 1366 x 768 support 1080i? Wouldn't being able to support 1080i mean that the vertical resolution would have to be at least 1080 pixels?
 
You said it yourself: it supports it. That means its possible to input 1080i, the tv itself scales the input to its native resolution, 1366x768 in this example.
 
Yeah, it supports it but a tv with that res is usually referred to as 720p.
 
so in other words.... having 1080i input and not having a tv that can display 1080i is really stupid?
 
1080i is actually two fields of 1920x540 that are interlaced. But, all LCD's are progressive, and if you have a 720p LCD, it won't really matter. You aren't going to see much of a difference at all (if any) between 720p and 1080i on that television.

There is so much scaling and interlacing/deinterlacing that goes on it is rediculous. I don't know why they don't just make a standard and stick with it. 1280x720 native resolution panels and 720p broadcasts would make sense, but why the hell do that when they can confuse the consumer? :p Thank god they did HDDVD and Blu-ray right with being 1920x1080p native being viewed on a 1080p television for an optimal experience.
 
If i wasn't so curious and if I hadn't just read an article about interlacing and deinterlacing I would have had no idea what you were just talking about. But I did so I do. :) It just made me happy.
 
Ok here is a new question..... Say I was looking at buying an HDTV but as the source for whatever I was using I was going to use a PC. Now I understand that graphics cards are capable of digital output and you can connect them to an HDTV with a HD cable with a D connector on 1 end and a DVI connector on the other. How will the quality of the output be effected? Will there be any problems connecting a PC to a HDTV? Will I get HD quality picture when I play movies on the computer displayed on the screen? Do PCs do upscaling?
 
You can hook your PC up to the HDTV. Just use HDMI or DVI for the best connectivity. Most people have problems hooking up to 720p televisions because of the overscan and resizing issues. It is an odd native resolution that a computer doesn't support. 1080p on the other hand will work perfect because 1920x1080p is fully supported by PC's.

For watching movies on the PC, your picture will only look as good as your source video. If it is a DVD, it will not magically look HD. If you want to watch awesome HD movies on the PC, I'd suggest HDbits, or go with a HDDVD or Blu-ray drive and a HDCP compliant graphics card and monitor/tv.
