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

Disable hybrid shutdown on win 10 to get rid off Win 10 amnesia.

 

Please tell your settings or post pic of timings, thank you

 

Thanks all, main post is updated.
Looks like the image host broke

---------------------------------------------
Gigabyte aero 15x v8
Panel is 1080p 144Hz AUO82ED (NOT the LGD05C0 that notebookcheck found in their sample - not sure what is up there)

Overclocked to 155Hz, no frameskipping. Custom timings. Using the panel's default timings for 144hz at 155 does not work.


Also tried 156Hz with slightly different timings which works too. Didn't bother checking for frameskipping as thoroughly but I am pretty sure it is fine.


If you want to test this panel be careful, if pixel clock is too low for a given refresh rate it will frameskip noticeably. I think it is 40pin eDP (the previous gen was) but can't be 100% sure.

 

my chimei(?) cmn15ca is crazy i7 4720hq can overclock to 80hz maybe ill try higher. so far no artifacts or frame skip xd
now im waiting someone that can mod easily hd to full hd

 

Would you mind linking me this panel? How would I go about overclocking the display? Do you know if this works for any 17.3 models? Thanks!

 

i have some question
when i get it to 95 hz or higher, i see pixelated apperance (hard to notice). how to fix it?

 

LG 15.6 inch panel can't OC well, very true, my Y520 can only get 62Hz (with reduced settings too), anything 63Hz or higher just don't show up no matter what settings

 

I read the whole thread but can't seem to manage to overclock my display.
Notebook is a Lenovo Thinkpad T440s, with i5-4300U CPU and Intel HD graphics 4400, Windows 10 Pro build 1803.
I tried with both the newest drivers (20.19.15.4963) and the recommended ones (20.19.15.4568), and both CRU 1.3.1 and 1.3.99-p1.
I can't manage to make the custom refresh rate show up in the Intel Graphics panel or the Windows settings. I tried with varying values from 61 to 65 Hz, even 55 Hz, none show up.
I tried installing the .INF monitor "driver" from Lenovo but that made no difference at all.
Current CRU settings are as follows:


Intel settings:


I am completely out of ideas. Any of you got some?

 

After adding those custom refresh rates you need to click OK and reboot PC for it to work. May I know which driver you're using and your CPU too?

 

Thanks for the reply. I did confirm the settings with the OK button, that is the window I see after the reboot.
CPU is an i5-4300U and drivers currently installed are 20.19.15.4963 (but I also tried the older, tested ones).

 

Got it to work on a late 2015 model HP Envy 17t w/ a 17in AUO panel. IPS Matte display - if that matters.
First tried on 75fps and that resulted in vertical lines. Dropped down to 72fps and seems to work. I definitely notice a difference when clicking start and seeing the start menu appear more smoothly.
Thanks

 

Anyone with a 3rd gen CPU (HD 4000) optimus setup get around this?

 

I've always wanted to see what the fuss was about playing games over 60 fps. So I took my Dell Inspiron 7567 with the easily OC'd AUO63ED panel and overclocked it to 90Hz. In Skyrim and Fallout 4 the extra smoothness is noticeable and aiming is a bit easier, but I'm not sure I'd pay a premium for a high-refresh panel. But, hey 90fps gaming for free is worth it.

 

From the Drivers section in the first post:

If you are running ivy bridge (or bay trail) or older, sorry: intel doesn't care and has ended support. Your best option is to try these workarounds which have not been independently confirmed.

• This post by jaug1337 describes a method to launch intel's custom resolution tool on driver version 4653, which is the last version available for ivy bridge generation graphics. This method does not work on Windows 8.1 because the 'custommodeapp.exe' is incompatible with the OS and will refuse to open.
  
• This video on Youtube: Pk0i2XJZQ7w uses some tricks to show custom refresh rates in the user interface, but it's unclear whether this method actually overclocks the display or just changes the numbers on the screen.
  
• On some drivers, you may still be able to overclock external monitors via CRU (source), not tested though.

In short, you're probably out of luck thanks to Intel discontinuing support...

 

I'm trying to overclock my ASUS GL752 with a CMN1735. It's a i7-6700HQ with a GTX960. My Intel Driver version is 21.20.16.4550. I've tried many times to add custom resolutions using CRU and nothing seems to come up in my intel control panel. I've tried various timings, HZ, while restarting each time and nothing will show up.

*EDIT - Does not work with new drivers, you must download the release one.

 

I used the Custom Resolution Utility to overclock my Lenovo Y50 Screen to 90Hz, after a crash I now see a pink screen with pixels overlapping. Did i mess up my screen by any chance or is there a setting that I need to reset. Has anyone seen anything like this?

The image of the issue:
https://imgur.com/a/b63c3Bc

 

Funny, mine OC'd just fine with default Intel drivers. They're either the ones pre-loaded by Dell, or maybe Windows Update.

 

I get the same damn error when Intel said they fixed Custom res on iGPU driver for skylake. I used CRU to OC my disaplay from 60 to 75Hz.

 

I don't think CRU supports 3rd gen optimus. Only 4th gen and newer.

 

So were you able to fix your screen?

 

Its still the same, it would seem that the burn in and ghosting is permanent. Looking to put an order for a new screen soon.

 

Sorry to hear that.

 

Managed to reach 64 Hz on a 4K/UHD XPS 15 9550 with a SHP143E panel. I mean, it is an improvement but it's so slight that it's unnoticeable. I suppose this barely counts?

 

has anyone tried overclocking the monitor on the asus rog gl502vm 15.6 ?? cpu is i5-7300hq with nvidia gtx1060 6gbvram

 

Hi, I am having trouble doing this at all. I updated my intel hd630 to the lastest drivers. I have a Acer Nitro 5 gaming laptop. After updating, I could manually set the refresh rate to 75 hz on the intel graphics control panel but it would just be black and revert back to 60hz. I tried doing the CRU route, but all I got was black screen and a revert. I am lost in terms of what to do. I saw that someone else was able to overclock to 100hz with the same computer so I confused.

 

Update: (Well not really an update, since I never posted my previous results here but anyway)

OCed my laptop IPS monitor connected with presumably eDP 2 lane (Model no. in description) to 74Hz. To be noted: Anything in the Detailed resolutions above 63Hz wouldn't work, giving me artefacts for half a second and going blank with only the backlight on. Only the resolutions in the standard resolutions would work, as I learnt today.


I could go higher, but anything above 72Hz, it seems, image quality drops significantly. So I ended up with 74Hz. No frame skipping either (100 ISO on phone camera).

Running on 23.20.16.4849 driver from 27/10/2017. Have no intention of updating the drivers because it is of little use to me. @margroloc

The image quality on 74hz is noticeably lower but bearable. Apart from calibrating the display in windows (adjusting that vertical gamma slider) is there anything else I could do to improve image quality and thus increase my overclock?

I've heard LCD screens overclock better than IPS panels, so I might try to overclock my old laptop's 1366x768 screen. Unfortunately, it might be on 1 lane eDP so its restricted to 165MHz

 

Hey, I tried this on my Acer Aspire 7 https://www.box.co.uk/NX.GP8EK.002-Acer-Aspire-7-A715-71G-53HF_2283341.html
(There are the specs and where I bought it from)
I set the refresh rate up to 75HZ, restarted and the screen isn’t rendering at all. I can’t figure out how to undo the changes I made, I tried resetting my laptop to a previous save point but I don’t have one as I haven’t had the laptop for very long. Please help me!

 

Success:
from 60Hz to 94.000 Hz

Alienware 13 R3, i7-7700HQ, GTX1060
IPS 1080p display (CMN1371 Generic PnP Monitor)
manual timing, copy-pasted from default timings
pixel clock at 239.42 MHz, will not go any higher

 

Success:
from 60Hz to 96Hz with LCD Standard/Native
Dont see any Frame skips while Scrolling (i am really sensitive to dropped Frames)

MSI GE60 2PE Apache Pro, i7-4710HQ, GTX860M over Optimus
15,6" IPS 1080p Samsung SDC324C (i can look up the real Display Name if you want, have to open up the Frame)

But: Climbing up over 80hz, the Display will start to Show faint lines on dark gray. It Looks like every second line is a Little bit darker. But it does not really bothers me, the Picture from a normal viewing distance is still fine.

 

I have exactly the same Problem with my ThinkPad X240, same CPU. I have other Laptops with this method working, so i know how to do it.
I think Lenovo is Blocking those custom resolutions, as they also have a Display whitelist in those machines. Could not solve it, the new refresh rates never appeared in the Intel oder Windows Panel

EDIT: I think i will try to interchange the Displays between Notebooks, i want to know if it is only a Display Limitation or if the Notebook is also decisive

 

I've tested more:

First, it seems that it only depends on the Display itself, the Laptop and it's CPU seem to be negligible.
Second, i would only see a "Success" at 80Hz+, everything less is not so interesting for me personally. But you can edit the Opening post like you want, if you want to use my Information.

So i used an Acer Nitro 5 with kaby like i5 7300HQ and switched the Displays:
FAIL: Stock BOE NV156FHM-N42 V8.0 is crap, could not do 70Hz.
SUCCESS: Samsung LTN156HL06-C01 (one on the few, if not the ONLY Glossy Antireflective coated Panel out there!!) goes up to 96Hz, like my previous tested LTN156HL01 (Post #178)
As in the other Samsung Panel, some very faint lines appear in Grey Areas, but it does not disturb at all, its almost not visible.

Other Laptops i've tested:

FAIL: Samsung Notebook 9 (NP900X3L Skylake Ultrabook) Samsung LTN133HL01-801 (also one of the few glossy antireflective Panels, only in 13,3" instead of 15,6"), could only do 70Hz
FAIL: Acer Swift 5 (Kabylake Ultrabook) with 14" AUO-Display, will look up the exakt model numbar also. Only goes up to 65Hz.

I only use "LCD Native" Timings.

I hope i could help

 

Did you try using CRU? I am pretty sure the main post is outdated now. There are new drivers for HD4000 + windows 10 and there might be a chance that changes in CRU will stick now.

Sorry to see that. First time I've seen this process break a screen.

Are you sure the other person had the same display? Lots of laptop manufacturers use multiple displays in same model laptops.

Hope you were able to solve it. For future reference: Try plugging in an external monitor and resetting the settings that way. Run reset.exe in the CRU folder to clear the settings, or change the refresh rate back to normal in windows. You could also try booting up in safe mode and uninstalling the intel video driver (DDU).

Thanks for your testing

Updated the main post with all the results so far. thank you everyone who has posted.

 

CRU doesn't support HD 4000 (3rd gen CPU based models). Only 4400+

I already tried CRU and the latest drivers, unfortunately it's just unsupported.

 

I fixed all my flickering problems for both 60 and 90+ Hz
Access Intel Graphics Control Panel -> Power -> DISABLE Panel Self-Refresh for both On battery and Plugged In

 

Hi there, thanks for this trick. Just to let you know that I get 72 Hz maxi with my Razer Blade 2016 GTX 1060, FHD screen.
Stable a 72 Hz but this seems to be the limit after hours of timing tweaking. I choose to use 70 Hz for Nvidia whisper mode (can't choose 72 FPS).
However, this operation still have some risks. During this, I had to reboot the laptop a lot and after a while, the screen got full grey at start … impossible to see the desktop or whatever. Must hard reboot. I thought, I had loose my display.
Well, I guess the pixel clock limit is 240 MHz but CRU automatic timing can't match Something good above 72 Hz (only LCD Native at 72 Max worked + 72 with default 60 Hz timing settings.)



I realy can see the difference playing Overwatch with vsync at 70Hz. If some of you got higher rate pls give the settings !!

 

Hey guys, I'd like to know if I'm doing something wrong.
I tried adding like 61Hz, 62Hz or even 75Hz in CRU, but it never shows up in intel graphics panel. I thought I would be at least able to see it not work, like in getting a black screen or something, but I can't even select other refresh rates? However, Intel information center shows these new resolutions as supported. Does that simply mean that I'm out of luck with my panel?

By the way, my driver is 4963 so I guess it's okay.

 

Manage to get my dell inspiron 7567 BOE0690 FHD TN pannel to 90hz using standard timing with no artifact and frame skipping.

 

Intel hasn't provided OC friendly resolution customization controls as Nvidia has, and while there are exceptions there are also challenges introduced into the mix by Intel iGPU control panel customization that ruins display OC'ing for many.

Hardware: Lenovo IdeaPad U530 Touch, i7-4500U CPU, Intel HD 4400 graphics w/ nVidia GeForce GT 730M, 1920x1080 built-in LCD display
OS: Win10 x64 (ver 10.0.17134 Build 17134)
Intel HD Graphics Driver: 20.19.15.4963

I need 50Hz refresh rate so I can correctly emulate European (PAL) mode classic computers/consoles (such as Commodore Amiga) w/ V-Sync enabled.

Even after installing CRU-1.4, using it to add 50Hz display modes, and rebooting, the 50Hz display modes STILL do not show up in either the Windows control panel pages or the Intel graphics properties app. I cannot get 50Hz display modes to work at all. I thought the latest Intel drivers were supposed to have unlocked EDID override?

 

TLDR:
Successfully overclocked my monitor from 60 to 90hz.
ASUS G551JM, i7 4710HQ, GTX 860M, panel LG Philips LGD042C, 1080p, win10, driver 15.40.37.4835, 60hz -> 90hz

OC achieved using standard timings. Could probably push it a bit higher with custom timings but 90hz a great success for me.
Latest Intel drivers don't seem to work (15.40.38.4963), no custom resolution was shown. Drivers recommended in OP worked for OC but caused problems elsewhere: Resolution scaling kept resetting to 125% and my secondary monitor was set to duplicate instead of extend after waking from sleep or restart. Also overclock wouldn't stick after reboot. With 15.40.37.4835 driver I have none of these issues.

Overall I am very happy with the results. The difference is noticeable in everyday use and in games that can push 60+fps. Thanks!

 

Any guide for Coffee Lake user?

 

I am using it continuously about 3 monthes. Very much happy with a results.
Successfully overclocked up to 108hz on ASUS N550JV Haswell, HD4600 + GT750m
108Hz is a maximum, with an effective color workspace - about very low 1200K, or about very high 9300K [by using f.lux or similar]
Lower Hz amount allows more color temperature range.

Pros of using it:
1) UI, all apps are responding faster allowing over100 tabs in over100 browsers with smooth scrolling [win7]
2) Faster button response, easier to play in lots of games where reaction, framedata matters.
3) In games where it's possible to change game speed above 60fps [for instance 108fps in console emulators] gameplay is incredibly smooth

Notes:
1) higher then 60fps smoothness appear with a little blur
[I still very like sharp 100fps on old crt monitors with ability to see extra details]
2) very demanding games lagging\caching on a new stages\worlds for a first few seconds. Once it's done - stage changes become flawless similar to default 60hz
3) avoid fullscreen white images on color temperature close to 6500K [default]
4) high 9300K is very much effective for color-sensitive work

Artefacts that appearing in close to 6500K on white fullscreen images are:
1) flickering [painful, looks a lot like ~60hz crt]
2) hard crt shader effect [hard to read, to watch]

 

Display: LGD04A7
Laptop: Lenovo Y700

Only 62HZ shows up at 1920x1080 with default or automatic timings. (The default timings seem to be the "LCD Reduced" automatic timings.)
Higher refresh rates show up with lower resolutions, but result in a black screen.

Any help? Are there any custom timings I could try?

 

Same as the others, simplay use CRU

 

New Results
First of, i think it's ONLY dependent on the Display, the cpu an Laptop model is not important, as Long as you can choose the Resolution in Intel Control Panel after creating it with CRU (Thinkpads seem to block this)

FAIL: Clevo N957TP6 (i5-8600 Desktop CPU, GTX1060...) LG LP156WF9-SPP2. Screen stays black over 65Hz
Success: Same Laptop: Clevo N957TP6 (i5-8600 Desktop CPU, GTX1060...) Samsung LTN156HL01-C06 90Hz+ without Problems, as Always a faint darker in every odd Pixel line.

 

Well, since third gen 9(Ivy bridge) graphics don't support this method and I can't use PEG mode (Optimus only). I went ahead and had my friend help me flash my EDID in Linux. My laptop now has 85hz available everywhere.

I used CRU to add the resolutions, then exported the EDID and flashed it in Linux using edid-rw. My friend is lazy and won't make a tutorial sorry.

 

Nice, and very good to know that that still works on modern cards. That panel is quite an odd one, btw ...

For flashing edids you could use my guide or Mr. Fox's from the '8 beep bricking thread'; it's the same tools, except for a different goal.

Just be careful when using AW Edid Editor when making the custom edid. This program always writes a 256-byte edid, even if the original is 128 bytes. The tools can write both, but you don't want to write 256-bytes to a 128 byte lcd if they've used the next bit for non-edid firmware data.

 

Mild success on Sager NP8157 with LG Philips LP156WF6 using custom resolution in NV Control center. Went from 60 to 63 so 5% for free. Better than nothing I reckon but anything higher than 63 just blacks out regardless of whether I used reduced clocks or stock in CRU.

5% isn't really noticeable but I love tweaking so I am pleased with the increase.

An old ACER H233H that I am using as my extended monitor went from 60 to 74Hz which was much more noticeable but that panel is so old and washed out that getting it to 120Hz wouldn't have made me salivate, necessarily, as it just acts as an overflow for my web browser and word documents.

I am looking forward to trying this trick out on my desktop setup when I get back to the house, as well.

I would be interested in replacing the laptop's screen if anyone can recommend a good one with higher refresh rates. Looking around on google, I am just finding generic panels that don't have much info listed. If someone could recommend a specific model and possibly a vendor I would be mighty appreciative.

I'm in the middle of a pretty large graduate project right now so it's not something I would be comfortable doing just yet but I'll have a month to kill once this is over in a few weeks and am definitely interested in upgrading the screen.

I bought this laptop used so I didn't get to pick any of the options when I purchased it. It just came "as is"

 

I think you can do better using CRU at 75Hz. I have same panel with different subversion.
