I wish they would extend that for Desktop PC use but I have a 23 inch HDTV that I use at 1080 and it's great. That move to 1440 is well, I can't guess why you would do that. Those AMD GPUs on laptops typically can't deliver gameplay at higher resolutions. I helped a lot of folk by pulling back to 768 lines.
