Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Well, it's still a TN panel, the LED is just a backlight, instead of the traditional CCFL backlights. LEDs translate into longer lifespan (not that it really matters), "instant-on" rather than having to warm up the bulbs, and a brighter screen.
Most likely, it'll be brighter, resulting in more vivid colors and maybe better contrast. But google around, read some reviews and see what people are saying about it.
