si_edgey Hey! Seems you did not understand my solution completely. I did not have to try multiple G-Sync laptops.
Since disabling Intel HD Graphics on the problematic laptop solved my eye-strain problem completely and I was able to look at the screen for hours without any issues, that was conclusive proof that Intel HD Graphics was the root of all evil, right? So what I needed was a laptop that DID NOT have Intel HD Graphics in it - completely removed or disabled out of the box by the manufacturer. Now, how did I find such a laptop? With months of scouring dozens of forums, I learned that laptops the have TWO Nvidia cards OR Laptops that Support G-Sync have the Intel HD graphics culled by the manufacturer else G-Sync won't work. Culled as in you'll never have to install Intel HD drivers and the manufacturer's drivers download page will not offer Intel HD drivers for download.
Users complaining about problems with Nvidia card are perhaps mistakenly concluding so. What happens with most of the non-gaming, non-Gsync supported, general use laptops is that the display is connected to Intel HD Graphics which is in turn connected to an Nvidia card acting as an auxiliary. In such cases, the Intel HD card does most of the lightweight graphics processing, and the NVidia card kicks in only when there's a demand for heavy-duty processing. It does the processing and passes it on the Intel HD card which renders it on the display while adding to it all that causes eye-strain and headaches. So it's quite obvious that the uniformed user might think Nvidia card also causes eye-strain. I've been on the Nvidia forums for months reading every single post and comment, and I didn't find anyone complaining of eye-strain with Nvidia specifically. All the complaints were coming from people who also had Intel HD card in their laptops alongside the Nvidia card. Nvidia is on top of their game. They release driver updates twice every month, and sometimes thrice or more often. Above all, Nvidia listens to users and so any eye-strain issue will have been dealt with before becoming as widespread as the current one which has made all of us on this forum suffer.
The problem free, G-Sync laptop I am using currently is the 17 inch Acer Predator G9-793. I bought it years ago and it has never given me the slightest viewing problems ever. I'm on it all day - for work, for gaming, watching movies, and everything else you can imagine. I have Acer's proprietary Bulelight Shield enabled on it all the time. it came with windows 10 Pro, so been using that ever since with automatic updates. Also the Nvidia drives update automatically and regularly. Never had any issues.
If you're skeptical, just pin point a G-Sync laptop online and then walk into a store selling it and ask for a demo. Take you problematic laptop with you and compare them side by side. Always check notebookchec.net for a review of your laptop and see if the display uses PWM. Mine does not (PWM not detected!), and that's what you want to have in your new laptop.
I still remember those helpless days when Intel HD made me suffer. I lost so much with my work and I had to start wearing glasses which I'll probably have to carry lifelong now. I consciously search Google for "laptop eye-strain" from time to time and always take the time to post my experience and solution so that no one else has to suffer as much and start wearing glasses. I feel it. It's worth investing in a good G-Sync laptop than buying a regular Intel HD laptop and having your eyesight damaged. If I ever meet the creator of that particular Intel HD card in person..... you guess what..
