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.
I don't know what the best 15" monitor is, the market has moved to bigger monitors. All I ever hear about is 17" and ups.
What you noticed about the size of the monitors is one of the big selling points of lcds. They are measured by viewable screen size, not cabinet size. So a 15" lcd is similar to a 17" crt, 17"->19" etc etc.
The best ones are definitely those from CMV, the 520D is 16ms, 500:1, 350nits (i think) and costs $170 shipped from memorylabs. The 529A has the same specs but its vga only.
A very good monitor for the price, I have used several of them so far and the quality is very good. I put the panels in my DIY LCD projectors
