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?

Not that I know. Where did you read that?

Question RE: Custom Resolution Utility (CRU)
Sorry for frequently asked question but how display refresh rate (hz) overclock affects display response time (ms)?

Smth like that?
Dell G3 17" and worst case scenario - LG Panel.
60Hz 25ms by default.
75Hz max overclock.

Before:
60Hz - 60fps - 1 frame per 16ms and 25ms delay
75Hz - 75fps - 1 frame per 13ms and i am lost Blush

If the monitor has overdrive, the response time can appear better or worse at different refresh rates depending on how the overdrive is tuned. If the monitor doesn't have overdrive, then it doesn't affect the response time.

Are you talking about response time or output lag? Monitors that lag usually can't handle higher refresh rates without skipping frames, but laptop screens usually don't have lag.

RE: Custom Resolution Utility (CRU)
I encountered an issue that I couldn't find an solution for...

I currently have "MSI GS70 Stealth" laptop and I did succeed in overclocking the built-in display a year back up to 75Hz (Did not try going further, even though I did notice here that some people got it up to 100Hz with no problems on the same or similar laptop). The problem showed up after my disk drive got corrupted and things led me to reinstall Windows 10. I'm trying to overclock the built-in display once more and I can't seem to make it work, so I'm here, now as a last resort, requesting for any ideas or a way to solve this problem.

About the problem:
I followed everything down to the letter, yet the custom resolutions doesn't appear in the resolution changing dropdown menus and etc, even though there is some proof that I did succeed in adding the resolutions? Here's a screenshot of what I'm talking about...

[Image: jnJ7OOb.jpg]

As you can see, I'm running the EDID override supported drivers (that were recommended in this thread) - it does say that supported modes are resolutions with 60Hz and 75Hz, yet the dropdown menu doesn't display them? wtf? I tried rebooting the laptop, reseting, restarting drivers via given tools and all kinds of ways to make them appear - no luck... Heck, I even tried checking BIOS settings, maybe after the reinstall I screwed something up, but there doesn't seem to be anything that could have an affect on this, so I'm out of ideas...

Any help would be appreciated
