Custom Resolution Utility (CRU)

[br0adband]

I've looked over this entire thread twice over the past few hours and I'll bet that I'm just missing something simple that might help me resolve my issue, but since I haven't seen the missing info I decided to join and present the situation in the hopes it might help me get a working resolution - pun very much intended.

Anyway, long story short: I have a ThinkPad W541, has the Nvidia Quadro K2100M "Optimus" setup using the Intel HD Graphics 4600 as part of the CPU (Intel i7-4810MQ). Using the latest drivers provided by Lenovo - as I want the system stable, and I don't game, so the latest drivers (Intel = 10.18.14.4414, Nvidia = 388.75) are perfectly acceptable to me.

This W541 has the Flexview 2880x1620 IPS panel in it and I run it at 1920x1080 which is also perfectly acceptable. I was going to do some work that would actually be more efficiently done at 2560x1440 and since I've literally got pixels to spare I'd like to be able to add that resolution to what I've currently got available but of course the driver INF files go like this:

1920x1080
1920x1200 (makes it show "black bars" and while I hate saying that you folks know what I mean)
2048x1152
2048x1536 ("black bars")
2880x1620

It's a bit crappy to have such a jump there knowing that because of the native resolution of the panel 2560x1440 should be an option and I don't know why Lenovo/Intel/Nvidia decided it shouldn't be.

So I downloaded CRU 1.3.1 and, well, it won't let me add that resolution of course, now I'm somewhat stuck as to why. I've researched this thread and just can't seem to grasp what I might not be seeing so, I figured I'd toss the info out there and see what happens.

I am including a few screenshots of CRU info, not sure if that will help or matter at all. When I attempt to add a resolution of 2560x1440 it won't let me, the text I type turns red and the OK button remains ghosted so, I suppose I need to do a lot more reading which I will do but in the meantime if anyone might have some suggestions or tips I'd greatly appreciate them.

Thanks, and have fun, always...

       
       

EDIT:
I was able to track down the Custom Resolution portion of the Intel GPU control panel but - ironically - it tells me this when I try to set 2560x1400 which is a lower resolution than the panel's native resolution:



If I hadn't seen it with my own eyes I might not have believed it.
