Same counts for " the how bigger the tv , the better" statments.
Even if the tv is "full HD" the image quality reduces if the screen gets bigger. Because of the fact that the resolution stays the same.
No matter how big the screen is.
So it's best to get a "good"size TV. and maintain the recommended viewing distance.
( basicly this makes all tv the same......)
If you'r sitting at a distance of 2 meters, it would be very stupid to buy a 40" tv.
On topic: upscaling only occurs if the Native resolution of the panel is higher than the input signal.
Downscaling occurs when the Native panel resoltution is lower that the input signal.
This is done by the proccesors in the tv's. And only applies to lcd and Plasma tv's.
Native resolutions work best, progressive inputs are second best. ( tv does'nt have to de-interlace the signal )
ALL flatpanels are natively progressive.
Some tv's have low end processors, and it will take some time to scale/ deinterlace the image on screen.
This is called latency or when gaming , input lag.
Other tv's do a good job at processing the signal or have a recommended "gamemode" setting.
This basicly disables all fancy processing and can result in lower input lag/ latency.
The upscaling feature in these Wiihdmikey and alike does'nt to any thing to the resolution of the signal.
It "scales" the image to fill the screen. See it as zooming in on a picture, it does'nt make it sharper - just bigger.
If your tv is very slow at processing, you could benefit of the HDMI key scaling feature.
This is what up/downscaling is. Nothing more and nothing less.
All flatpanel tv's upscale if the input signal differs from the panels native resolution.
Some tv's can disable scaling. This will result in the original image resolution displayed on the screen.
So for the Wii signal you would see a little box in the middle of you screen excacly 640x480~720x480 or 640x576~720x576 in pixels without scaling.
So upscaling is needed and all tv's have upscaling or input a signal in native resolution.
This is also the reason why the Wii signal does'nt "look" any different on a HD or HD ready tv.
Resolution does'nt change, only image size. The screen is simply filled.
