It's 12x12"; you want to buy the teflon that's treated on one side, so the double sided tape will hold it down.
If you buy the untreated type, you find out why teflon's so valuable.
I bought it from MSC for ~$20, IIRC. It's ~10-20 mills thick.
Some mice won't track on it, IDK if it can't see variation or not. But the G900 works great.
I would post a pic, but I'd have to clean my desk; so not happening.
Speaking of Ghetto mods, I've been replacing caps in one of my monitors for my eyefinity setup.
I get finished, and Plug it in, it comes on and all, but then I realize I forgot to plug in the cables for the backlight.
Every one of these monitors has failed exactly the same way; there's a 100uF 16V cap on the 1.8V regulator, and it loses it's forming layer, and isn't a capacitor anymore.
I replaced these with Polymer 2.5V caps, we'll see if that will last.
EDIT: OK after you take an ASUS VW266H apart 5 times, it gets easier, lol.
I did leave the backlight connections unconnected, and it works great now. Back to 5760x1200 res.
BTW, if anyone has the problem with these, where the picture gets corrupted, and draws static everywhere, and gets worse when it's cold, replacing C223 on the Logic PCB will fix it.
It's a 100uf, 16V cap on a 1.8V circuit, and the capacitor loses it's forming layer, due to not enough voltage.
Replacing it with a 2.5V 100uF cap works great, and shouldn't ever fail.
