My Yoga Slim 7 gen 8 has the exact same panel but mine is only true black HDR 500.
How dit they get the trueblack HDR 600 certification for the exact same panel?
It is a pity they didn't use a newer panel with HDR 1000 and a better PWM. They did it with the ideapad pro G10, a cheaper model.
My laptop is the best except for the PWM. It makes my eyes tired with prolonged use. Now I am waiting for the Yoga Slim Gen 10 that has an HDR 1000 panel and probably a better PWM. But the newer has only 4 speakers (mine has 6) and it is 14in (mine is 14.5in), damn Lenovo.
