I don't know if anyone else has mentioned this before but my X1 now accepts 1280x1024. I tried 1600x1200 but it was a no go. The only reason I can come up with for this is the 4800 firmware. I've been using the 4800 1.3 firmware since it came out but never bothered to mess with the resolutions until the other day. I will confirm this when I switch back in the next day or two.
