In any exchange, Dell cannot "choose" the revision. You simply get the next one queued up. I am curious as to what they told you? I have no idea how Amazon would handle this.

* I was told that A06 would start shipping from Dell in August of 2017 for NEW purchases
* Was that A03 purchased NEW directly from Dell? Or purchased from the Dell Factory Outlet?
* What are both 20 digit S/N? Check the monitor labels, not the boxes
* Send me via Private Message the service tag numbers
* Both should be set to Factory defaults =
- Press the Menu button
- Go to Others
- Choose Factory Reset On

All I was told was if purchased new, the monitor would have the latest revision installed. The only way to really know the version would be to enter the Factory Service Menu and check the firmware version. But I do not have that instruction. Another S2417DG user would have to discuss how to do this.

The S2417DG and Nvidia G-SYNC 165Hz are tricky. The latest Nvidia driver must be installed, you must be using DP to DP. Images should be tested using =
* all of the Hz (60/85/100/120/144/150/155/160/165)
* all six Color- Preset Modes
* Display- Response Time Normal and Fast

So lots of configurations to test to find the best one for you.
