    MakaaiD  dwitch 1440p (and more) rates will be supported on both RK3328 and RK3399 from next nightlies - so presumably from tomorrow on.

    Yay, I have 2556x1440@60, thanks much !

    There are still a couple of additional modes exposed by 4.4 with my 144Hz Dell - most of them probably won't be missed, except for the 144Hz one :)

    Hi Knaerzche,

    I have a 1440p screen for which the 4.4 rockchip kernel does a decent job with rk3399. With a couple of printk I got my hands on the would-be-mpll_cfg that (I thought) would allow to configure that mode.

    However, when adding a mode this way into mpll_cfg, it gets rejected by vop_crtc_mode_valid with MODE_CLOCK_LOW, as when requesting 241500kHz the clock only accepts to grant a 198000kHz rate - where with the rockchip kernel, dclk_vop0 can really be set to 241500 (with parent dclk_vop0_div, taking its source from vpll). Can you see any obvious reason why the VPLL would not be able to deliver this clock rate ?
