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.
21:9 29"=wider 23", consoles do not support 21:9 resolutions and the1440p monitors are better anyway.
List of the best 1440p Monitors. I recommend the EV2736W since it is glow free, followed by the EA274WMi>VP2770, BL2710PT and iiyama XB2779QS but be warned, it uses Plasma Deposition Coating, though the ZR24W has awful black levels so the iiyama XB2779QS will likely be a huge improvement.
The U2713HM suffers from regular quality control issue (light bleeding and pixel issues) as well as matte coating cross-hatching, image retention and some revisions suffer from really obvious overshoot ghosting. The U2713H is one of the worst 1440p monitors for gaming. This information is from the list I linked you to.
