Now i do notice this X9 has 1200hz so now wondering why the screen was bothering my eyes? any help would be great as for it my favorite laptop ever.
1200 Hz is high enough, typical mobile screen has around 250 Hz only. There may be a diferent issue. The display resolution (density) is quite low for a 15" screen (I'd accept 4K at least) and OLED use different subpixel matrix than LCD screens that looks more unreadable in low resolutions. I've seen a 1920x1200 15" OLED that was absolutely awful, there were always red shadows next to white text on black background as a result of the low resolution and different subpixel matrix. I wasn't able to use it at all. 4K screen was ok, as the resolution is high enough to hide it.
Subpixel rendering should not be used on OLED screens because they are usually designed for LCD subpixels and may cause weird colored artifacts around text. It's nice that Windows allows you to configure the type and parameters of text rendering on each display separately.
My laptop has an 15.6" OLED screen where pixels are so dense that the type of rendering doesn't make much difference, though. Text is always extremely sharp so that you can physically approach the screen to read tiny text, e.g., in PDFs, instead of zooming in.
