</span>I suspect the driver has removed any modes that it can't support due<br>
to a lack of memory bandwidth or a support level (e.g., the 4K modes<br>
on your monitor require DP 1.2 and your card only supports DP 1.1).<br>
What chip is this? You'll probably want to provide your xorg log and<br>
dmesg output.<br>
