Custom Resolution Utility (CRU)

I have used this CRU last time like 1 year ago and I installed 1440x1080 60hz custom resolution with no problem, thank you for that.
Now I have 144hz monitor (XL2411Z v4) and I'd like to have same custom resolution with new and faster refresh frequency.
I have updated drivers, Blur buster strobe utility detects my display and I get normal resolution with 144hz on from AMD CCC.

Thing is that when I add "Detailed resolution" with 1440x1080 144hz into the CRU and restart the graphic drivers, that resolution doesn't add up into the resolution list in CCC or in-game like CS:GO.
Tried switching numbers in "sync width" and "total pixels" back and forth and it doesn't change a thing.. Only with very wrong settings after graph driver restart screen starts to flicker very badly..

If you have questions I'll try to reply asap and thank you again.

Driver rejected your resolution. You're using 1) wrong timings for 144hz and 2) pixel clock is 449 MHz! Driver will reject any custom resolution if pixel clock is higher than 330.00mhz unless you are using Pixel clock patcher or displayport.

Even if you use pixel clock patcher you will get an "OUT OF RANGE" error.

***EVERY** 144hz refresh rate that you are trying to display scale *MUST* used REDUCED VERTICAL TOTAL. Even 800x600@144 or 1024x768@144. (the problem with these really low resolutions are CRU wont reduce them properly (LCD reduced wont do anything) so you have to reduce it manually even more, or u will get out of range...
But that's sidetracking....I only mentioned this because some stubborn person recently INSISTED on creating display scaled 800x600@144hz and refused to use GPU scaling one :/ haha)

-------------
Easiest way if you want 144hz 1440x1080 is to create 60hz one.
H: 1440, V: 1080
Automatic--LCD standard timings.
60hz refresh rate.

Or manual (if you REALLY want).
front porch 48 pixels, 3 lines
sync width 32 pixels, 4 lines
horizontal total: 1600
Vertical total 1111.

This will add 1440x1080@60hz to driver.

Then the other refresh rates for 1440x1080 will be GPU scaled automatically. Then you can use 100hz 120hz or 144hz as you want.
Driver just needs base resolution info to GPU scale the other refresh rates.

If you REALLY REALLY REALLY REALLY want to create DISPLAY SCALED 1440x1080@144hz (I don't suggest it but if you really want to): you can try:
1440x1080@144hz
AUTOMATIC-LCD REDUCED.
(manual settings are
front porch 24,3
sync width 32,4
horizontal total 1528
vertical total 1095
refresh rate 144hz.
