This is getting so depressing. My 3rd attempt at getting a good G9 has sadly failed.
The first one (N6) had bezel bleed, moderate popping noises as it heated up and a noticable fade to gray for around 1cm along the full width of the display along the bottom. On the plus side, it didn't have the scan line issue, it had no dead pixels and didn't have any flickering issues (except the odd rare flicker on loading screens).
The second one (N8) had horrendous flicker issues (including flickering between cooler and warmer colours), the horizontal scan line issue and dead pixels.
The third one (N9) that just arrived a couple of days ago is also has annoying issues. On the plus side, it doesn't have flickering or dead pixels, however it does have:
1) backlight bleed issues making it seems washed out in darker areas when in HDR mode which is saddening when viewing darker scenes with brighter highlights in particular portions of the screen. Neither the N6 nor N8 had that problem, at least not noticeably (especially not the N8, it was definitely better than the N6 or N9 when it comes to blacks in HDR mode).
2) Bad case of scan lines - I've seen it occur in games, but more frustratingly, the scan lines appear with my normal desktop background, or if I load certain pages that I use like the
Spotify web player. The N6 didn't suffer from this at all and the N8 suffered from it, but only when running the
UFO inversion uniformity test page (or the
asus rog wallpaper website). Perhaps it did happen in games on the N8, but I didn't notice it, because it didn't have the next issue...
3) Coil whine noise whenever the scan line issue occur's. (Neither the N6 nor N8 had this)
4) The fade to grey at the bottom (about the same amount as the N6 one that I had)
Of all the list above, the thing that gets me the most is the scan line issue, if that could be fixed, then I'd probably be happy to keep it.
This is so depressing - I love the G9, it has so many great qualities and is the perfect monitor for me on paper. So don't want to say this, but I really don't know whether or not to try again or just give up.
