RE: Custom Resolution Utility (CRU)
Is it possible to reduce the pixel clock without reducing the Monitor's refresh rate?

RE: Custom Resolution Utility (CRU)
hi guys, anyone with these monitors that can provide me with a little review about them, which one is better and if any of these or maybe another one with the same specs that's better and if can be overclock?

34" CF791 Curved Widescreen Monitor

or

ASUS Designo Curved MX34VQ 34”

What exactly do you mean with this:

The video card will not reduce clock speeds when idle if the vertical blanking/total is too low. Horizontal values can still be reduced if necessary.
AMD/ATI cards require the "LCD standard" vertical blanking/total to reduce the memory clock when idle.
It means what it means. I don't know how else to describe it. The memory clock can't change if the vertical blanking/total is too low, so it will always stay at full speed. RX-series cards can clock down with lower values. Older cards require the "LCD standard" vertical blanking/total.

What about with LCD standard?

Yes, by reducing the blanking/totals.

Thank you for the reply, do you think that's possible to reduce some of my laptop screen blur & ghosting (trails of "whiteness" and "blackness" left behind when I drag windows around and scroll text) by messing around with those settings or reducing the pixel clock... or am I talking gibberish?
My screen's response rate isn't great and I know there's not much I can do about it but... it doesn't hurt to ask I guess ^^''

RE: Custom Resolution Utility (CRU)
Hello ToastyX,

I'm trying to increase the refresh rate of my LG UD69P-W, which is a 27" 4k display. I'm using a GTX660. I've tried using the CRU tool, however, my refresh rates don't appear in my Windows setting after creating a new profile. I have tried both deleting all but the one profile, as well as simply adding a profile and moving it up to the top of the list. I've googled around this thread and I've seen you recommend disabling the extension block, but I'm not sure what that means as I haven't seen any checkboxes that say "disable extension block" anywhere in the tool. Does this mean simply deleting the extension block that is already there when I run the tool? I'm running the latest driver from Nvidia (398.36), and I have tried this with both GeForce experience installed and not installed. Deleting the standard 60Hz option (the native one) does reflect in Display Settings, however, and leaves me stuck on the 30Hz option. Also, when creating a new profile in LCD - standard, the hertz option becomes red at 74 hertz and higher, and in LCD - native, anything 67 or higher also becomes red.

If you have the time to spare helping me out, I'd much appreciate it. Thanks!

GTX 660 is limited to 540 MHz pixel clock with DisplayPort, and I doubt that monitor will support more than 60 Hz.

RE: Custom Resolution Utility (CRU)
I've been reading that it's possible to "force" a Nvidia GPU to function with FreeSync. Is that true?
