高清一問
我知道高清標準係1080i, 咁係咪等如720p?但電視機resolution要去到幾多才可以support? 1080i = 1920点 x 1080点 單線
720p = 1280点 x 720点 倍線
電視機分兩種:
1.支持高清 =非真正点對点支持, 而是將之壓縮成1280x720 / 1366 x 768
2.真正点對点支持=1920 x 1080 解像度 , 目前有 sharp / benq, Sony 就快有 [quote]Originally posted by [i]d228216[/i] at 2005-8-30 09:46 PM:

There is a misconception that 1080i is better then 720p.
In truth, 1080i only provide a larger image, but 720p has a better picture.
Because 1080i is Interlace, it only refrash 540 line every cycle. 720p is progressive, so it refresh 720 line all at once. 1080i image will flicker in some cases, easy to see if you use projector or your screen is large.
The current highest standard is 1080p. Samsung has TV that support 1080p already. However, I can't find any signal for 1080p yet.
Anyone know where can one find 1080p signal?:D:D
