360hz vs 240hz
-Very Bright - 360hz over 240hz feels like a more snappy and responsive 240. Ive been on 240 for almost 2 years and used many different 240 panels and the Asus 280hz. You can tell the difference.

The 6 Best Monitors Under $500 - Spring 2022
Sadly, it also has a low contrast ratio that makes blacks look gray, the black uniformity is poor, and it doesn't have a local dimming feature to improve either of those. Although it has decent HDR peak brightness, enough to make some highlights stand out, it doesn't display a wide range of colors in HDR. Besides these small issues, it's an excellent gaming monitor that's the best choice for esports gamers on a $500 budget

Why the weird names on monitors?
* AW2521HFL = Alienware, 25", 2H 2020 release (2021 model year), 1080p, VESA Adaptive-Sync, and the "L" stands for "Lunar Light," because this one comes in two colorways. Dell tends to release their monitors in 2-year refresh intervals. So, if the 3418DW/3420DW sees a successor, it will likely be called the AW3422DW, and be released the 2H of 2021.

Is this a good configuration? I use my PC for everything and I'm a fairly hardcore gamer. I use a Dell 32" 2560x1440 AMD Radeon 165Hz monitor, if that matters.
I honeslty would not recommend pre-built, especially from " Dell Alienware" the worst company out there.
Dead On Arrival (Terrible Customer Service)
I Typically enjoy Alienware products and was looking with great anticipation to add this monitor to my setup, however when I plugged the monitor into my GPU and wall socket a few things happened: 1. The Monitor was receiving power but the screen was DEAD 2. My computer recognized the second monitor....

The 5 Best 24-25 Inch Monitors - Spring 2022
The best 25 inch gaming monitor with native G-SYNC support that we've tested is the Dell Alienware AW2521H. It's an excellent gaming monitor with a 25 inch 1080p screen and an incredibly fast 360Hz refresh rate. It has native support for NVIDIA's G-SYNC technology, delivering a tear-free, visually consistent gaming experience, even when your frame rate drops

Aw3821dw came wit a tiny crack on the panel (no dmg on the outside). It’s only visible when looking at the monitor from above. Could this get worse?
Where I am at least, they will send you a new screen and pick the old one up at the same time. So your only downtime would be between packing up the old one and unboxing the new one. You've paid a premium for a Dell Alienware, and part of that is the warranty, make use of it.
Fast AF Boi
does what you think it'll do if you need this kind of monitor. most people don't, but if you know you know with this kind of thing. surprisingly sharp colors, G-SYNC that actually works, solid build quality, honestly just a great panel.
