iPhone 17 Pro DC Dimming Aftermarket Display Success
I had success swapping out the OEM display on my iPhone 17 pro max with the AMPLUS aftermarket display by MobileSentrix to get rid of the nasty 480hz high modulation PWM!!!
I posted on forums online looking for mobile phone repair and someone had mentioned a dude named Zac who owns Quick PhoneShop in Punta Gorda, FL. I contacted Zac and explained that I need a very specific OLED panel. He mentioned that they had an XO7 panel and AMPLUS and I asked if there was a chance that I could just see the XO7 panel and test the PWM bands with my other phone before they seal it up and he said yes so I really really really appreciate him letting me do that.
The XO7 had 480hz PWM similar to the OEM display so they put on the AMPLUS and as expected, it had DC dimming! Another shop about a year ago had given me an XO7 (as I was told) by mobilesentrix on an iphone 14 pro max and that had DC dimming however when I tried on the 16 pro max and 17 pro, both XO7 were NOT dc dimmed anymore.
I will say, the headaches and eye strain are significantly reduced to the point of the phone being usable as a daily driver but there is some very mild discomfort. The display has a mild green tint but otherwise has fantastic colors and brightness is very good. The interesting thing is if I set the "disable pwm" option in accessibility settings to on, it seems to INCREASE the modulation and the black line gets thicker. I will do more testing to see which is more comfortable.
In the meantime I am so glad I am able to have a usable 17 pro and again huge freaking thanks to Zac for being patient with me through all of this and letting me test the different displays before committing to installing it. As of right now the only confirmed one with the DC-like dimming is the AMPLUS.
I asked Zac if he would be willing to do installs for people who wanted to mail in their devices and he said he would be happy to and confirm with his phone that they do in fact have the DC dimming before mailing it back. If anyone wanted to get this done, just call their shop and ask for Zac Quick PhoneShop - (941) 655-6681
I will try to get some photos up later as well of the thicker bands when I use the display pulse smoothing feature in accessibility settings!
