I know I want a 2-4x 1080p display to have a full HD (or better) picture with a polarized 3DTV.The effect probably is similar to the sbs videos you can find, which look pretty good in 3D, but sometimes you can see the (horizontal?) resolution isn't as high as it should be.

Afaik "glasses free" 3DTVs need ultra high res displays aswell, as the resolution is divided by the amount of viewing corridors(x2).

That all still displays at max 1920x1080. You don't really need the extra resolution for full HD 3D.

Current glasses solutions are either lcd shutter glasses for at home with the tv alternating a 1920x1080 picture at 120 or 240hz. Or polarized glasses in the cinema where there are 2 2K projectors at 2048x1080 each with one of the polarizing filters.

Glasses free 3D tvs use 4K resolution panels but they use a perpendicular lenticular sheet to direct the light to a number of different points in the room. Each eye still only gets a 1080p image and you have to keep your head in the same spot. (1 of 9 sweetspots for the currently available glassless 3D tvs). Moving your head from side to side or tilting your head will ruin the effect. No racing games for me on such a tv :)

I don't really have a problem with wearing glasses as long as they are cheap and don't need to be charged. Maybe they can make oled/lcd 3D tvs for polarized glasses. That can be done with a 2160p panel by polarizing every other pixel, or polarize the light at the source at 120 or 240hz and alternate the picture on the 1080p screen at the same rate.

For comfortable glasses free tv you'll need a panel that can adjust the sweetspots dynamically while tracking your movements. There were experiments with that 5 years ago, but it only worked for 1 user at a time on a pc monitor and I haven't heard anything about it since.

Otherwise this is where we're at now for best quality glasses free experience, for now you'll have to choose, either wear glasses or sit still.
