40" 1080p Bravia. Jaggies are noticeable, if you're sitting quite close to the TV that is and keep staring at them. Otherwise, from a bit of distance, it's fine.

Does a WiiU even work with a Sony TV?

;)

Back in 2008 I was actually worried to put my Wii next to my PS3. So far though, they've been getting along pretty well. No incidents whatsoever.

It's not a matter of optimization, but simply correct resolution. The game runs at the native resolution in the gamepad. On your TV, it is running at 720p but on a 1080p screen. The scaling hits the image quality badly and even a very good AA solution wouldn't looks as good as 1080p without AA.

This thing is easy to observe in games that are direct console ports from the PS360 to the PC, without any graphical updates. But only by running the game at 1080p instead of 720p it just looks better and there are less jaggies. I would take 1080p no-AA instead of 720p + TXAA or SMAA anyday. It makes sense since aliasing is an artifact caused by the rasterization process, so more pixels automatically reduce aliasing.

Okami in PS3 used a nice technique where they rendered internally the game in 4K and downscaled it to 1080p and achieved amazing AA results. Mots AA techniques of course are much simpler and consist in some edge-detecting method that wii detect and blur edges in the aliased parts to improve image quality.

So you are saying I need to go back in time and buy one of thos "HD ready" TVs for the best image quality for MK8?

I've set my Wii U to 720p output instead the default 1080p. A lot of games end up looking better this way , have fewer jaggies, and better framerate IMO

looks great on my 50" LG

i have to sit further away from my 47 inch when playing wiiu games to allow it to look better. it does help.

If you had a 720p TV, jaggies would be less apparent because the TV woudn't need to upscale the image. Upscaling always brings quality issues, except when you are doing for a resolution that is multiple by the same number in vertical and horizontal pixel count and is integer (like 1080p to 4K where you have 2X the width and 2X the height. 720p is 1.5X, so it needs scaling).

Anyway, a 1080p TV is newer, so it will likely have better contrast, colors and so on. But if you tried it on a 720p TV that was exactly as good as yours in all aspects, the game would have less jaggies. But you probably won't find a 720p TV with this kind of specs, so it's better to get better colors, contrast, brightness and so on in a modern 1080p set even with some jaggies.

I have a 48 led 1080p and it looks better than on the gamepad. There are no jaggies at all on either, but the tv is much brighter.
