I've both the LCD TV (32inch, HD-ready, 1360X768), and LCD Monitor (22inch, 1680x1050).
Wii supports max resolution up to 480p only (with component cable). The quality is much lower if u use normal AV cable.
Since it supports max only 480p, in order to get an acceptable graphic, u should NOT connect ur Wii to high-end TV/monitor(eg: full-HD), instead, u SHOULD choose from below in sequencial order:
1. Normal CRT TV (due to low resolution of the TV, it matches with the resolution of Wii)
2. Plasma TV (if u have older plasma TV series with resolution 800*600 roughly, or 1024*768, then still can consider match with Wii resolution)
3. LCD TV ("half-HD, means 1360*768 series, and must use component cable to get 480p out from Wii console)
4. High-end display (LCD monitor/full-HD LCD/plasma....etc), all will end up with pixellize graphic even if u use component cable, since Wii max output only 480p)
I myself am using 32inch LCD TV(1360*768) with component cable now, and it is still acceptable. (of cos u can't compare with Xbox360/PS3 as their max output is at a diff level).
Note: read from some reviews that if u rily wanna use ur LCD monitor, the best is to connect using the "VGA Box", which is something u need to survey by urself since i didnt pay much attention into it.
Really well explained. And here i thought i had all detail last i did my research. Never quite know got max resolution to wii and the needs to buy component cable to adjust it. These days buying thing become quite complicated.
