I have GU605M, which is the 2024 asus rog zephyrus. I had the issue where on grey background and/or low brightness I could see grainy particles or "noise" if you're a photographer. This have been a big deal since, and I'm looking forward to use this laptop for 4-5 years. This is unacceptable. I've emailed asus technical support, but unfortunately no reply.
