About this deal
The default EDID CTA-861 extension block type doesn't allow for a front porch above a value of 63, so for some reason dell compensated that by increasing the back porch value to 15 (not sure why). overshoot/coronas) and the preset, which they labeled as "normal" is much closer to that perfect balance.
I'm guessing it's input lag is great but pixel response is slightly higher than other 240hz because it's colors are way too good. In other words, the preset labeled as "super fast" (for example) now has what I assume to be roughly the same amount of overdrive gain attached to it, as the "normal" preset has in non-VRR operation.However, if the most important thing you look for in a monitor is speed and responsiveness, then thanks to the impressive gaming tech on board you’ll be well served by the Alienware 25 Gaming Monitor AW2518H. One should use the overdrive preset, which results in the least amount of image artifacts, not the one which is labeled the most eye-catchingly. I don't remember the settings exactly since I sold the monitor, but I can check later if I saved it somewhere on my PC. There are other changes and tweaks I found through the service menu (voids warranty), I will post more about it when I have time. This allows for a dynamic refresh rate, which will eliminate screen tearing and stuttering without significantly increasing the input lag.
Follow the UFOs with your eye and observe the amount of ghosting/overshoot you see with your gsync+super fast "fix" in place. On the back of the screen, three LED lines, along with the Alienware logo, can be illuminated and configured to display a range of colors using the AlienFX technology, which you can sync with your other Alienware products, or even compatible games. The pixel response time speed of 1ms GtG eliminates visible trailing behind fast-moving objects, but such fast response time is nowadays available on IPS panel displays as well. These comprise a power connector, DisplayPort, line-out audio port, USB port, headphone jack, three USB 3.However, if you’re looking for a monitor that will fully immerse you with eye-popping resolutions and vision-filling images, then you’re better off looking at monitors such as the ultra-wide AOC Agon AG352UCG. You're not increasing input lag (which you seem to confuse with response time) by using a lower pixel overdrive setting, and vice-versa, you're not decreasing it, by using the preset, which they misleadingly labeled "super fast". It’s quite a good collection of inputs, though it doesn’t provide the older type of connections, such as DVI.
