The M2 fab is a classic 8G fab essentially.

It allows for 6-up production of 55-inch displays because it doesn't require cutting the sheets in half.

A 55-inch display is 1216mm wide, which fits into the width with enough space for edge handling and cutting.

It's 685 mm tall, which fits into a 3-tall format.

What it doesn't do is fit into a half sheet and allow you to make four displays. Period. You would never cut to the 1100 dimension, you'd only get two. Instead, you'd cut the other way and and you'd get three. This is presumably what they'd done with M1, cutting the sheets "early" and getting the same total output.

You can't magically get make displays off of half sheets, however. Basic math should make that clear.

It should similarly be clear that making 65s and 77s is much less efficient. Once you start cutting those sizes out, you get waste that can't be avoided.

There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working. (Oh, and plasma didn't die because of logistics problems, nor does OLED ship in big boxes because it comes from Korea.)
