soseono · 02-09-2012, 08:21 PM

I've been noticing that something's wrong with the greyscale/contrast of my T1's screen, especially font anti-alias/rendering. The fonts aren't drawn smooth, but rather jagged, and look fuzzy. Since I prefer small serif fonts for reading, this bugged me a lot.

So I made some greyscale test images, in 32 greyscale. I know that T1's spec is 16 greyscale, so understandably there's some emulated greyscale display in between. But you can see in my attachments (the first two) that there are a few points where the grey block isn't clean and straight, but more like checkered.

Anyway, I wonder if it's just my unit or if this is a rather widespread issue. I'm also attaching the test images, so please tell me what you see on your T1.

(The small gif is the original that I used to create the test images.)
