PSA: You can now overclock your laptop monitor [intel/intel+optimus]

So, I'm having some issues here guys, hope I can get some help.

Recently bought a Dell IS 7567 with i5 7300HQ (Kaby Lake) sided by a GTX 1050 and Intel Graphics 630.

I tried to follow @margroloc steps but, funny, I'm stuck in the most basic stuff. I can't get the driver to be correctly installed (the BETA one, which's been tested). It says windows can't verify the driver's signature.

Yes, I swear I installed it by using the .inf file as described in the post, but when I restart the laptop after installing it, I get this signature stuff message. Should I disable driver signature enforcing? Or maybe the driver ain't compatible with my laptop?

My current driver gives me the option to try customized resolutions, but I get that "maximum bandwith exceeded error".

To top it off, I think I'm not even handling CRU correctly. I follow all of OP steps but can't even get the new refresh rate to show in Intel Graphics control panel. I can confirm that I tried every possible combination from 63-75hz, switching between "Manual" and "Automatic - LCD reduced" settings, and could not do it.

As an additional info, CRU names my panel as CMN15D2.

 

Dont do it. Not worth wasting your time. I already tried it on CMN15C4 panel. The panel manufacturer is same for you and me. The highest i can get is 62hz from 60 hz. Even other posts confirm that the panel with 'CMN' as a manufacturer do not overclock so well. Two other person with same panel manufacturer were able to go up to 63hz only.
As far as the driver issue, i clicked on the link posted by the margroloc. There,Intel promted me that a new latest driver is available released after this version.
So, i downloaded that latest version and indtalled it using that inf file method. It asked to verify the installation as it is not digitally signed by Microsoft. I allowed the installation.
After that CRU started working, i was able to add custom refresh rates.
But the max overclock i was able to achieve was 62hz.

 

Whoa, thanks, guys.
This works on my ASUS A451LB (or maybe called S451LB) Internal Display (eDP, AUO323C, 1366x768)
I can overclock it to 90Hz without any glitch/frameskip/artifact (or even 98Hz but have some frameskipping).
I can also overclock my LG-22MP58VQ to 75Hz without any problem I've mentioned before. Going further shows OUT OF RANGE
Now I feel the smoothness of 90Hz on my laptop

PS :
1. Intel Driver used is the latest available driver for Haswell, 20.19.15.4624, dated 3/8/2017
2. Do not try to overclock it above 90Hz on AUO323C or you'll get artifact (Yes, I have tried it, OCed to 120Hz or even 200Hz on lower resolution (It still can manage the Pixel Clock below 120Hz) but the result is screen artifact, fortunately I have an external monitor to reset the configuration)

 

Well, yeah, that may be unfortunate for me. As for the CMN, however, I think it stands for the Chi Mei manufacturer. The dude who first posted in this thread apparently could do some good overclocking. Well thanks for answering tho. I've already spent a ton of time trying to do this. I was hoping to reach at least 75hz, which would make some nice difference. Imma do some other tryouts tho.


Edit: could get CRU to work with the .4627 driver. Couldn't go nowhere past 60hz tho. Even 62 would not work. Now I can say CMN15D2 does not overclock.

 

I have a Gigabyte Aero 14 with a LG panel LGD049A ( LP140QH1-SPF1) . Default supported max display settings are 1440p@60hz reaching eDP limit of 238/7 Mhz. Even a slight bump to 62Hz@1080p results in instant black screen followed by running vertical lines across the entire screen.
If anyone succeeds with this panel , please report

 

Monitor overclocking results:
Aero 15 CMN15C7
62hz, anything over resulted in artifacting / weird duel screens. Disappointing.

 

Hello guys,

First post to say thanks for this. I've done this to my
Acer Aspire V15 Nitro VN7-593G-772Y. The results are pretty decent, it's gone to a stable 70mhz which is definitely noticeable (72mhz+ doesn't work at all). On initial boot, I will find it flickers for a brief 1 second before returning to normal for the entire session. This is absolutely fine IMO and worth doing.

60mhz to 70mhz may not sound like much but it is a 15% increase that otherwise costs nothing and gets better animation quality and just general smoothness in any application that can make use of it.

EDIT: Model Number (model is from store in Australia)

Thanks!

 

Hi Guys,

This was an awesome post. I managed to boost my refreshrate from 60hz to 96hz! Which is an amazing improvement.
However, I have something strange going on.

My normal colours have slightly. They look a little bit more 'pixelly' if you know what I mean. Its a very small but noticeable change. Do you know how to change this? Reverting back to 60hz seemed to have changed the issue, but this... obviously... is not what I want.

Anyone has any tips?

 

Hey guys, I'm running an MSI GE62 6QF with a 970M. I've followed all the instructions, however, when I go into the Intel control panel or Windows settings to change the refresh rate, it blacks out my screen for a few seconds and then reverts it back to 59Hz. Is there a way to fix this? Or is my screen just not capable of running at more than 60Hz? Thanks for any replies!

 

What refresh rate do you set it to?

Also what CPU do you have?

 

I have a 60Hz monitor on my GT80 Titan...I wonder if its safe to overclock it? Does it have a long term effect on the monitor?

EDIT:

So I OC'ed using Nvidia Control Panel custom resolution to 96Hz...everything seems buttery smooth now.

 

Seems I can only get 63Hz. Anything above that and it just reverts back. Is this the max I can OC it too? Because someone else on this thread with the same laptop as mine OC'ed his to 90Hz. I've got an i7 6700HQ.

 

MSI GT80 Titan 6QE...OC'ed from 60Hz - 96Hz - 100Hz - 120Hz. It's like having an actual 120Hz on this thing that the manufacturers doesn't want us to use...however I didn't follow the guide instead I use Nvidia Control Panel to set custom refresh rate.

 

My GT80S 6QE Titan doesn't have optimus so when I installed Intel Driver it says:



How do I proceed to the next step?

 

Nvm...I skipped the installation of Intel Driver and proceeded to CRU and set my refresh rate to 110Hz.

Unlike before I used Nvidia Control Panel to set a custom refresh rate but in-game settings won't let me pick that custom refresh rate but with CRU I now able to set the custom refresh rate to 110Hz with DSR enabled.

EDIT:

Finally...I set it to 110Hz...max I can get.

@ margroloc @ToastyX Thanks for the guide and the tools! Everything is now buttery smooth.

 

Are you sure you have the same panel as the other guy? Sometimes even with the same model laptop that's not the case.
Anyways if your screen is blacking out then that means whatever settings you had weren't stable. You could try to adjust the timings but otherwise I think you might be stuck. Maybe get in touch with the other guy and if you guys do have the same panel, copy his settings?

Your laptop doesn't have optimus so the display is running off the nvidia GPU which means you can either use CRU or the custom resolution tool built into the nvidia driver. The intel graphics driver wouldn't be useful for you at all. Great that you already figured everything out

 

May I ask how do I adjust timings in CRU? And what timings do you recommend?

 

Hey, may I ask what panel you have?

 

FOR IVY BRIDGE USERS (Intel HD Graphics 4000) WHO WANT TO OVERCLOCK THEIR MONITOR WITH OPTIMUS

So @James D with his video managed to OC his monitor using a flashed IDID and then changing it via the method in the video in Windows.

HOWEVER, I found the second method. This has worked for me, without failure, on 3 Ivy Bridge laptops I've used it on. I reached 75Hz on 6 cheap displays.

1. First, make sure you have the newest Intel HD Graphics 4000 driver, download here.
2. Click Windows Key + R (launches Run), in there type the following: "C:\Windows\System32\CustomModeApp.exe" (without quotes)
   
3. From there the magical window that controls custom resolutions, that is hidden in the menu, is shown.
   
4. There you go! The thing to remember is to keep the pixel clock to > 225Mhz for HDMI.

P.S. All of this was done on the W10 Creators Update, couldn't make it work on one laptop running the Anniversary Update.

I am now wondering if I will be able to use a 2560 x 1440 @60Hz using custom resolution and HDMI 1.4 ... but who knows.

Good luck folks.

 

After a few experiments I finally got my laptop monitor (Chi Mei 173HGE-L11) stable at 95hz, can reach 100hz but with a little artifacts on the desktop (videogames and movies seems fine thus).

 

@margroloc

An excellent video demonstration on how to OC a laptop's monitor (for visual learner)

 

See this screenshot for what I mean: http://s7.postimg.org/lc9ba1p4r/manual_timings_info.png
As for what timings to use, I have no idea. Hopefully someone with more knowledge about display timings can answer

Could you clarify what you mean by step 3?
Do you mean that the 'custom resolutions' window in the intel control panel shows up? (sort of like this?: http://s3.postimg.org/7tx2xscab/screenshot_2017_07_26.png )

EDIT: Nevermind, I did more research and the custommodeapp is just intel's custom resolution tool built into their driver control panel. Somewhere along the line intel realized their tool was broken so they removed it from the driver and shoved it into an executable hidden in the System32 folder. The custommodeapp won't run in windows 8.1 by the way but will work in Windows 10. I'm curious whether it will actually work for overclocking the built in display though.

 

Yes exactly.

Intel's custom resolution tool broke a few displays and furthermore, always was broken. However, launching it manually, works! And yes, it works on the built in display.

Sad to know it doesn't work in W8.1

 

Hey, I'm not the same guy but I own a MSI GE62 2QD-276US Apache Pro and was able to overclock my display up to 100Hz (Didn't get past 105Hz). I7-5700HQ+960M. I have the SDC324C screen on my 15.6 inch laptop and the screen is made by Samsung but not much info is available on it.

I installed the latest driver and played around following the directions on the first post. I used the LCD Reduced settings and 100Hz was fine with no flickering. When I don't use LCD Reduced I'm only able to get to 90Hz without flicker, so use that setting. I also tested with https://www.testufo.com/#test=frameskipping this tool and had absolutely no frame skipping. My settings: http://i.imgur.com/ZFhtb5B.png

Some weird behavior I noticed is that when I overclocked the display to 60-70Hz I had bad flickering but after I got into the 80-100Hz Range using reduced it worked perfectly with no flicker at all. I never had a black screen until I tried 105Hz. Tested in games and my settings are select-able there and work great.

I usually lurk and made this account to post this, hope it helps (Might not check again). Check your display model. If it's the same it should be good.

 

So... Was able to push from 60 to 100hz on my Asus Rog GL552 using default monitor values.... At 105, the display turns black..
FEELS PRETTY GR8 AT 100

Edit : After trying out 105 now at 100 flickering is hugely visible.. Any solutions to this or my display is fked now? Whereas earlier when i tried 100 after 75, it seemed to work perfectly.. No flickering n stuff.

 

Try selecting "LCD reduced" like I did here: http://i.imgur.com/ZFhtb5B.png

There's weird behavior that nobody seems to be able to explain. Like I had flicker at 60-70Hz but no flicker at 80-100Hz. In any case, if you still have flicker it should be no problem to settle in the 90Hz-96Hz range. Maybe when you went from 105-->100 there was a setting that didn't properly save so you still get the flicker so when you go from 75-->100 there's no issues. Always try restarting your computer too.

 

Restarting didnt help.. So after a few hrs of display running , flickering went away itself n now its perfectly normal.. yea maybe the display didnt revert back properly from 105 instantly. And at that time it used to flicker even on 75.. Ty for the help tho EZ 100hz masterrace xD

Edit : Random flickering is till there.. HZ doesnt matter.. even on 75 it occurs. Seems like something is fkd up..

 

The first time overclocking I pushed the display too far and it went crazy. So I started to drop the refresh rate back down but the screen was still glitching out occasionally at settings that were previously stable. I got super scared and thought I wrecked my display and because anything slightly beyond 60hz (61hz, 62hz etc) caused the screen to still glitch out once in a while.

I was going to call it quits until I realized that while I was overclocking the display the first time, I changed the timings to try and get some stability. Turns out that I switched my timings to the 'LCD-reduced' preset, which caused the display to go crazy, but while dropping the refresh rate back down I never changed the timings back to the default for my display. So afterwards whenever I kept trying to overclock and adjust the timings, I never managed to get close to settings that were previously stable. After realizing this and starting over I now have this display at 104hz and it's been working fine since last year.

Point is: try deleting all the CRU settings to go back to a stock config, then work your way back up again. Maybe you changed the timings a little bit without realizing it made the display unstable? Worst case, if you want to go back to default refresh rate & default timings you can nuke all of CRU's EDID overrides via 'reset.exe'

 

Very logical explanation. I also experienced the same thing but did not know it.

 

Well i used my stock monitor timings but i'll try this. Thanks.

 

Someone tried overclocking Acer's VN7-592g with IPS screen?

 

MSI GE72 6QD Apache Pro 17.3 Inch Skylake with the Chi Mei CMN1735

was able to be OC to 85Hz with native(norma) timings and 90Hz with the LCD reduced setting. Good result as from what I noticed here, the Chi Mei panels don't OC as well as others. 17.3 inch panels do well as somebody pointed out earlier.

Always worth a try guys and if you try it... come here and post your results!

 

According to: https://www.reddit.com/r/Monitors/comments/5qop2d/lg_philips_lp156wf6_overclock/ and http://forum.notebookreview.com/threads/any-way-around-64hz-panel-limits-lg-lp156wf6.784658/

The LG Philips LGD046F LP156WF6 doesn't overclock to anything more than 64Hz.

And the aftermarket screen: IPS BOE NV156FHM-N43 does not overclock to more than 65Hz

Just compiling some information!

 

Does anyone know where you can buy a LGD04B9? I think I need to replace my monitor as it sometimes doesn't turn on in the morning and when I move the lid forwards/backwards it can go black.

 

Did anyone try this with an ASUS K501UW?

How well does the ASUS laptops handle overclock in general?

 

What laptop is that from? If It's from the Dell Inspiron 7559 for example, browse the thread here: http://forum.notebookreview.com/threads/owners-thread-dell-inspiron-7000-series.734278/page-182

Or (better way) just google your laptop model and "screen replacement" followed after it to find experiences of other people changing their screen. Usually they will link you to that panel that they bought. Most 15.6 inch laptops have easily replaceable screens but you should youtube the model first to see if someone has done it.

It has nothing to do with Asus, it just has to do with your display panel. As long as you have a Intel cpu with a compatible driver posted in the first post of this thread, you can try it and see how it does. Every model is different, 17 inch monitors do better than 15.6 models but it's worth trying. If it's the same panel model ID, the whole lot should OC similarly.

 

Got my Dell 7567 recently, put a different panel instead of TN, model number is AUO41ED
96hz with native timings
108hz with CRU reduced
110hz with a little bit manually lowered timings
No artifacts, no frameskipping. Might be due to by 6-bit color depth.
Great experience overall, overclocked GPU and display in one day

 

Pro tip: Don't set ur hz to 10 and let it be the only possible setting - will make ur screen not turn on properly

 

Hey guys, this might be a dumb question but is this possible if I've got (crap) dedicated graphics in my laptop, since it works with IntelHD integrated graphics?

I'm using a Dell Inspiron 7560 so it has NVidia 940MX as well as an i5-7200U, which comes with Intel HD 620.

Any clarification is appreciated!

 

Hey, it should work no problem. Be sure to install the correct drivers for your CPU first. This driver makes it possible to set custom panel profiles even with intel graphics. Report back to us on how you do and what screen model you're on.

 

Great, thanks - I think it was quite an ignorant question, but I'm not sure where the stupidity lies! Currently at 75Hz with no issues, still increasing incrementally. In terms of screen model, a quick google search says the only way to find out is to take the screen out and have a look at the label on the back, is this correct?

 

Device Manager --> Monitors --> Generic PNP Monitor --> Properties --> Details Tab --> Drop down menu select "hardware ids"

Should be there.

 

CRU just got updated to 1.3.1

https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

 

BOE06B4, got it to 75 but found anything higher to be unstable with lines appearing across the screen. Thanks for your help!

 

For a 15.6 inch screen (they usually don't OC well) getting it to get 75 Hz is still pretty good. That's a 25% increase in refresh rate. And you're welcome.

 

Dell Inspiron 7567 with the AUO63ED can reach 108Hz with Reduced timing and 96Hz with native timings. Could reach 110Hz with manual, will update when I do so.

This is the IPS FHD display and not the TN. There are two models of the IPS which is the AUO63ED and the LGD053F which comes randomly I believe though I purchased mine in a bestbuy store around the time I make this post. No frame skip or artifact or flicker. Perfect display with what seems like amazing colors (to me at least). It seems that AUO displays do very well.

The LGD053F is reported to not even OC to 65Hz, so if you can... try to find one with the AUO! Somebody suggested just opening the Laptop in store and looking at the device manager to see which model it is... not sure how that plays out.

Also to install the up to date Intel drivers on this system, what you need to do is first install the Dell Intel drivers from Dell (if not already installed). Then update it manually through device manager by directing it to the newly downloaded intel graphics zip file in the "graphics" folder. Hard to explain, easy to watch through youtube tutorial.

 

Can confirm, Dell Inspiron 7567 with the LGD053F, on 15.45.19.4678, the very best I could do is 65Hz, kind of bummed out I didn't get a model with the AUO63ED. Would have been nice to get close to 120hz without actually having to switch to a TN panel.

Speaking of, does anybody know the full model number of the AUO63ED panel? Wondering what the price difference is between that panel and a real 120hz TN panel.

EDIT:
According to this post, the AUO63ED may be an AUO B156HAN06.3 or a similar variant.

 

If you're from the UK/EU You can order a 120Hz panel that works with the dell for like 45 pounds. http://www.laptop-lcd-screen.co.uk/shop/AU-OPTRONICS-AUO-B156HTN05.2-15.6-NOT-120HZ__183900.asp A user here did it and said it worked but you have to adjust brightness through software if you want to adjust it.

 

Has anyone else found they cannot overclock it to the same limit in optimus mode rather than discrete?

Perhaps a pixel clock limit in the Intel driver?

 

Is it possible to downclock the monitor using this?
