Can I overclock the AUO V.4 95% NTSC Screen Refresh Rate above 60hz?

Let me know if this is possible please, I've heard that many LCD screens can be OC'd to run at above the stock 60hz, possiblye 70-90hz, I would love to go up to 80Hz stable but I know this may not be possible; even 70hz would be a good improvement. I plan on buying an external 120hz refresh rate screen next year either way but it would be cool to OC the AUO to 70-90 hz if it was capable and if it wouldn't harm the screen or its lifespan.

 

It'll hurt the screens lifespan alright, but the screen are so durable (if not hit) that they live even longer than the actual laptop...

check THIS out, really the only way of doing it and if it doesn't work.. well then nothing you can do

 

Juag you are always helpful ha I wonder If anyone on NBR has ocd this panel before I think I may have heard rumors somewhere of it going to 70 Hz . Which is still a big jump from 60. Almost 20percent

 

It's a mix of the panel and the GPU.

Haven't seen being possible on the AMD GPU's... only with nVIDIA chips in their main control panel, and that's only on some panels too.

I don't it can be done man but hey nothing is impossible, you can try your way around, try searching on google, I will research later today when I come home.

 

Thanks a ton for the help; + rep for sure

Yeah I read through that thread again I forgot thats the one I found a while back and it made me curious. I wonder why AMD GPU's can't do it. I know the 7970m could run many games over 60 FPS. There has to be some sort of software / modded driver somewhere -_-. Such a rare need/mod though haha.

I think I actually gave my last rep to you I'll have to rep you tomorrow haha

 

yes i have done mine all the way to 95hz, and its stable, but just to be safe i backed it down to 90hz, and it works flawlessly. and yes i have the same screen as you, but i have an nvidia card so im not sure if you will be able to do it.

 

Why do you say it will hurt the screens life span jaug? What exactly does it do to the screen and what evidence is there of this?

I am curious about this too, I need a fast refresh plus 7970M though. Anyone with that combination get it working?

 

I get mine with the set up next week I'll test it.

 

I think it hurts the life of the screen just by the fact that they're rated at 60Hz. Sure they may be able to handle 75 or higher (some actually say 75Hz on their spec sheets) but the point is that they're tested at 60Hz. Running them faster just stresses the screen more, which naturally leads to a shorter life. There's no telling how much shorter, but shorter none the less.

However, as mentioned above, the LCD panel will probably work long after the computer is outdated and not worth using as a modern machine for work or play.

 

For AMD, There is a reg edit floating on the internet for custom refresh rate, but it doesnt always work. I tried to force my external to 48 or 72hz for 1080p24 but no luck.
There is also PStrip, but it dun have much support for mobile GPU.

Edit: 1 more is to edited the EDID of the monitor but it is kind of a PITA.

bottom line is, find a way to OC first.

 

My point is I think often times people put disclaimers on things just out of fear of the unknown rather than actual information. Has anyone ran an OCed LCD for 6 months then seen it develop a problem? Running things faster does not always put more stress on it.

Lets not think or guess lets know. And if we dont know simply say that we dont know. For instance everyone likes to say if you OC a CPU it reduces the life but the fact is I have NEVER in my life killed a CPU by OC, in fact I have never seen one go bad period. And in reality you know that intel and AMD sell the exact same CPUs at many different frequencies. What we know is that there is a difference between a "safe" OC and one that pushes it to the edge. We also know the mechanism behind damage, that is heat that cannot be dissapated melts parts of the CPU causing damage.

So when I think about that I say the most likely cause of failure is an OC DAC burning up. But if you run it at a reasonable frequency just like CPUs that will never happen, ever. Then there is the claim in here that it might do some damage to the pixels. That one has no evidence I am aware of at all. Pixels can try to change anyway they want sending the signal more times is not causing an increast in heat that I know of. Now I am not an engineer for LCDs so I don't know but I think it is not appropriate for anyone else with no more information than me to say that either. We should just say, do it at your own risk, but I really dont know what that risk is.

 

The method is ancient.

Proof? Well THIS and the even older THREAD

Well your screen does not officially support it, but the reason for this (I would assume) is because it can support and work on these refresh rates.
- Not necessarily something it was designed for but definitely something the screen/monitor can do so I would only think that it should shorten it's life by some margin.... no sure though, just thinking logical

 

I'm not saying you're wrong but:

1) your anecdotal evidence is nowhere near a large enough sample size to make any judgement
2) if the normal lifespan of a CPU is 20 years and OCing it reduces that to 10 years then the lifespan is definitely reduced but does it matter since you're probably going to replace it in less than 5 anyway.
3) overclocking definitely adds more stress to the unit be it monitor, GPU or CPU, the question is not whether it adds more stress it's a question of whether that stress reduces the lifespan and whether the reduction will ever be seen. Hell underclocking would reduce the stress but again who cares if it'll last 20 years instead of 10 if you only plan on using it 5 years anyway.

No matter what clocking you use, it causes stress on the device. Just pumping AC through solid state electronics causes a certain amount of stress. The manufacturers pick the lifespan they want, set a conservative clock (so 95% or whatever % last the lifespan they require) and then that's what they rate it at. Just that conservative rating alone means that some percentage will last the same lifespan at higher clocks. Overclocking is just deciding that you want higher performance and are willing to trade off the lifespan that you don't think you'll ever need anyway.

 

I tried to OC the screen through Intel graphic control panel and this is what I get: http://forum.notebookreview.com/sager-clevo/660283-you-guys-know-you-can-overclock-lcd-6.html#post8615741

Screen is output is managed by the iGPU so we EM users might have to find a different way to OC the screen.

 

1) I did not claim that there is no problem, I simply stated that anecdotally I have never run into a problem. And without anything else to go on I have no reason to believe that there ever will be a problem.

2) And the reverse is true as well. You are restating exactly what I said. The point that no one knows. If you run a sample of CPUs for 9 years you still have no idea if they will on average make it to 10 or 20. You have no information. So why make the claim it might only make it to 10?

3) These are all valid questions you have here, but my question was what evidence is there for any of this? I have yet to see any. I see this too all over the internet people say if you OC you your CPU you reduce the life. One could say that if you use your CPU you reduce the life. But until someone can actually quanitify that how do we know anything? Never once have I seen a link to an actual study. People just assume this. As far as I can tell anecdotally safe OC on CPU, and monitors has no affect on lifespan that anyone has ever measured. So until someone comes in and gives me that study we should all stop saying it does.

Here is another issue its not like a company can actually test a product for 10 years before they release it. So once again they dont know they try to do a failure rate test to get that info but that is not the same as actually testing a product over time.

Over clocking a monitor is not the same as overclocking a CPU, can you choose what voltage you are going to apply? Do you set a frequency? How do you know the DAC does not already opperate by default at a frequency way higher than any frequency you might have guessed?

 

I hopse someone with the 95% V.4 Matte display from AUO can test it with the 7970m or AMD card in general with the mod that Juag1337 posted,

this link

Download ATI Radeon RefreshRate Fix 0.9.9.7 Free - This handy utility let`s you set custom refresh rates for D3D and OpenGL. - Softpedia

try this and let me know if it works

 

wait what, my name is j aug1337 au as in a astronomical unit and the j and the g is basically my sir and family name

 

Jaug** sorry ha.

I hope someone can try this though; I hope to get mine OC'd a little.

 

I thought the screen is managed by the iGPU and dGPU only process the given contents? Or Enduro works in a different way than the Optimus?

 

You can only OC it via the dGPU, iGPU won't be able to OC it as there isn't enough bandwidth I believe. You can do it easily with the Nvidia cards like your GTX 675m, you use the Nvidia control panel and you can choose higher refresh rate [mhz]. It's simple for nVidia cards; I'm having trouble finding a way to do it with the AMD cards though; I'm getting 7970m and have no solid way yet except the possibility of that ATI refreshrate fix working.

My 7970m and machine are being built tomorrow and shipped out monday [got an update from Eurocom]. And have 2-3 day shipping so I should get it Wednesday if I'm lucky; but by Thursday for sure unless there is some major issue.

Got a new mouse and headphones and mousepad; just need the laptop now

Surround sound Gamecom 780 headphones are going to rock for BF3!!!

Need Planetside 2 and Warface to come out; grrr.

Not many awesome games out currently -_-; will probably get some Witcher 2 action going though as I hear its sweet.

 

The thing is I don't see any options for monitors in the nvidia panel.

 

First you have to enable Advanced Control Panel.

 

You mean through the registry like coolbits? Wait.. Does this even work with Laptops with Optimus enabled?

 

No you do it in the options for nvidia control panel I mean.

 

Well it seems like you can't change anything related to screen resolution and screen refresh rate via the nvidia panel when the Optimus is enabled because screen setting is managed by the iGPU. Otherwise it would already be showing up in the nvidia panel as a default option.

 

ok guys i think i may have a solution to your dilema, about a month ago, i was messing around with the driver for my 3d tv, and it turns out that if you install the driver for another tv for it, it pops up as 3d automatically without any software in the nvidia control panel. anyways i was thinking about this and discovered that by using phoenix.exe, an edid editor, and moninfo, i could create and modify my own driver which added additional options for my monitor as far as resolution and refresh rate.

i will make a post explaining this later in detail, if this successfully rectifies the problem, but for now i need someone who is willing to test this on their p150em, that has the auo v.4 95% matte screen, and a 7970m.

disclaimer: i am not responisble if something happens to your screen, but if something does happen i will do all that i can to help you return it to normal. I personally have this installed on my computer and the screen didnt even flicker or anything so there is really nothing to be worried about, but if something were to happen, just connect the laptop to an external monitor and delete the driver for your laptops display.

ok heres the instructions:

download the attached file, unzip it into an easy access folder

open device manager

find your laptop display, right click it and select update driver

click browse my computer

click let me pick

click have disk

click browse, and find the folder you unzipped the .inf file to

then click open in the .inf file

then select it in the box and click next

let it install and then click close

if all works correctly, nothing should happen, this is good, now reboot and under the refresh rates in where you select the resolution there should be some new refresh rates.

enjoy, please tell me if this works, im very confident that it will, but if it doesnt we will keep trying, thanks.

 

Would his work on a W110ER? If so, I'll try it after work.
.

 

aduy that EDID override inf is for the Lenovo LEN40B2.

You need to get a moninfo dump of the AUO with the existing timings first.

Then edit or fuse with the EDID timings from this.

I had to do a lot of EDID editing for my home theatre setup.

I should have my P150EM soon, at which point I'll help.

 

The custom refresh rate seems working in normal Windows environment.

But in Games using D3D or OGL the refresh rate seems go back to 60Hz.

 

Yes.

1234567

 

The W110ER doesn't have the AUO V.4 15.6" screen so no. You might be able to OC the refresh rate since you have a GT650 nVidia card though.

 

Nope it's still the same. I still get the message saying the custom resolution exceeds the maximum bandwidth capacity. And in the refresh rate I can only select 50pHz and 60pHz like before.

 

Hackness its easy with the nvidia cards, Google it. Lots of ppl have done it. Its only an issue when you use AMD cards

 

um theres an issue where the auo 15.6 v.4 screen gets updated to a lenovo driver, it works exactly the same, so nothing to worry about. also did you restart your computer, it wont work until after you restart.

 

ok try forcing a custom refresh rate, by saving it into the game settings file.

 

Those who have done it are using an Optimus one or a none Optimus one? Can you show me a link please?

Yes I restarted the laptop, it doesn't work, adding custom refresh rate still leads to the same message on the Intel panel, as the screen is managed by the iGPU I don't see there's a way to change it through nvidia panel.

 

Aduy did it with his 485m, so it should be similar with the 675m, his is non optimus but you can disable optimus and then try it I believe.

http://forum.notebookreview.com/sager-clevo/660283-you-guys-know-you-can-overclock-lcd-3.html#

people on this thread did it with the 560m and 675m from what i've seen ...

 

i dont think you can disable optimus, but you can add in your own custom resolution to the nvida control panel, if you have the refresh rate working in the normal windows already.

 

Well it's simply locked in the nvidia panel on mine. So far the game reads the supported resolution and refresh rate from the iGPU.

 

You have to enable advanced nvidia control options its in the menu. I used to do it with nvidia its easy.

 

have you tried changing the settings file for the game to a different refresh rate?

also the reason the display can go past 60hz at 1080p is because the connection between the display and the card is essentially a dvi cable link. perhaps the new em series just uses an hdmi type link to connect to the display and therefore doesnt have enough bandwidth to support a higher refresh rate. it could also be that intel has crappy software that wont support higher refresh rate screens. i think this is why there was never a 120hz 3d vision screen that used optimus, they just couldnt get the intel gpu to drive the screen at such a high refresh rate. I bet this is also why there hasnt been a p170em3, with the 3d screen.

 

I haven't tried with games tho. Which games allow you to implement the screen refresh rate profiles manually? I'll give it a shot.

 

The "used to" you mean is with an Optimus laptop or without?
The problem is this laptop is an optimus laptop so such thing isn't found on the P150EM in the nvidia panel.

 

go ahead and check in your documents, most games save the game profiles there, for example battlefield 3 and almost all games save the user data in a folder in "my documents"

 

I can't wait; just 3 more days until I set up my machine and test these methods out for AMD HD 7970m! Hah.

Now I'm excited for next year when I can upgrade to 8970m hopefully for the new Unreal Engine 4 games and Crytek Engine 3.5 / 4 whatever comes out.

My hobbies of gaming/graphic design/photo editing are going to be so much more epic on this machine haha. And accounting/finance software will be more bearable on this epic screen ha

 

has anyone figured out a way to OC the lcd with a switchable graphics setup? would creating a driver file for the LCD be a workable method?

 

I don't think the iGPU is capable of putting out more than 60Hz.

 

what about when you have a 3d display?

 

I don't think it's possible to run an internal or external display at 120Hz off these units:

http://forum.notebookreview.com/sager-clevo/682348-np9150-3d-vision.html

If correct it's a bit of a bummer really.

 

from that thread it would seem that one user was able to output 120hz to external monitor.. so maybe there still is hope. Does anyone know how to see current refresh rate? powerstrip has some options for refresh rate tweaking but its hard to know if they work.
