[9024844] Custom resolution not working

[RCarl6]

I emailed Intel Customer Support Service and they refer me to this forum because the agent say it will have the correct exposure to intel engineering department. (request # 8001214860)

The problem is Intel Graphics driver for HD 4600 (and presumably others too) have a broken custom resolution for Built in LCD. No matter what setting you put into it, it will always custom resolution exceeds the maximum bandwidth capacity.

I tested it on many different laptop with eDP (embedded displayport) like Alienware 17, Asus G751JM, Asus Q551LN, Lenovo Y50-70, Razer Blade 14, MSI GT60 Dominator Pro, and Gigabyte P34 and they all say custom resolution exceeds the maximum bandwidth capacity.

To establish the fact that bandwidth is not the problem, I tried creating a custom resolution at native res (1920x1080) at 59Hz (default is 60Hz) and it says custom resolution exceeds the maximum bandwidth capacity. To test it further I downscale the resolution to 1600x900 @ 59Hz and it still gives the error so I conclude the problem is with the driver itself.

I tried the oldest and newest driver from the OEM and the one on Intel website and they are all broken.

The problem is NOT ISOLATED on a laptop model or a manufacturer but the Intel Graphics driver itself.

In fact if you verify the problem by testing it on ANY laptop that has an Intel graphics and try to create a custom resolution that is 1Hz less than native (like 59Hz) and it will give you the same error.

So why does it matter? Almost every single gaming laptop that is being released are NVIDIA Optimus Enabled (Hybrid Graphics where Intel Graphics is handling the display) and it prevents people from changing the refresh rate of the display. As an example the LCD panel found on Asus G751JM-BHI7T25 uses LG LP156WF4 SPL1 which is the exact same panel found on Asus G751JY that comes at 75Hz by default, but we cannot change the refresh rate due to broken Intel Custom Resolution even though the LCD panel itself is more than capable to handle it.

Refresh rate is a huge feature as evident on monitors getting released (like BenQ XL2430T, Asus ROG Swift, Acer Predator, etc...) and if you ask any gamer that has tried a high refresh rate monitor they will tell you how much big of a difference it is and because of this issue, any gaming laptop that has Hybrid graphics (Intel Graphics enabled) is a HUGE deal breaker.

Old title: Intel driver is completely broken (custom resolution)

" to protect users from harming the hardware."

So basically nVidia and AMD are not protecting their users for shipping unlocked drivers. Nice statement.

"This was an intentional design of the driver. "

...to ship a broken Custom resolution feature. Why is it there in the first place on laptops, then?

We are being trated like complete idiots with nuclear stuff in our hands. How do you even dare to come with such a reponse after this thread's pressure.

I get it, we are the 0.01% of people who actually need this FIX. I wish I could have used my 860M without the Optimus bullcrap inbetween.

Older laptops without integrated graphics have this, but you are throwing the user's protection thing.

[DMitc4]

Just to add on to what you said, I have a GTX 860m in my laptop too.

Now I can understand that Intel wants to protect their customers from damaging anything, But why would you be messing around with

stuff you dont know nothing about? I pretty sure alot of the people who have been having these issues on this forum know how to do the stuff they are

requesting a fix for.

So Intel needs to allow this stuff to the people who wont accidentialy mess something up. Honestly over my Monitor EDID override experience

I have never seen a display on any computer or TV at that get damaged because of an high than supported Refresh or Resolution.

I have a Samsung Syncmaster 203b and on my old AMD based laptop (Without all this Intel protection mess) I managed to get its stock res from

1400x1050 all the way up to 2166x1600. Thats a massive push and I had it on Digital DVI. Either way the quality wasnt much of a difference other than the fact

everything on the sceen was really small because of how big the res was.

Even after that I overclocked the integrated monitor on that old laptop with AMD and pushed its refresh from 60Hz to 102Hz... Literally.

Some people cant even achieve 80Hz and I managed to get higher than 100. That just goes to show that AMD doesn't block their stuff.

I just don't understand that Nvidia and AMD didn't get 1 complaint about damaging their monitor because they pushed the resolution or refresh in that case.

And even if we did push our resolutions too far and something breaks its not Intel's fault. Its ours, So give us what we want.

[idata]

Semantics. It's just as damaging as a bug because nobody else locks down drivers to hardware EDIDs.

The idea that 'display manufacturers ship all products with sensible EDIDs' is laughable and utterly idealistic.

The fact that you lock your drivers down to these inconsistent and non-updateable hardware EDIDs is ridiculous.

The notion that we should be patient after five years of asking for basic and essential display driver functionality, is infuriating.

Because of Intel's over-zealous design ethos I can't use a monitor on my desk because it has a shitty non-standard EDID.

- Plug into Nvidia = runs at native resolution at 60hz

- Plug into AMD = runs at native resolution at 60hz

- Plug into Intel = ERROR BAD EDID, YOU MAY NOT USE THIS DISPLAY. WE KNOW BETTER THAN EVERYONE

Bryce, you obviously feel that our request is unreasonable.

And I'm sure In corporate-we-build-software-on-ridiculous-idealisms-land it is very unreasonable.

In the real world, where we all live and work, your company is the one being utterly unreasonable.

[FLast22]

the problem is not even the limits of custom resolution, the drivers were written poorly

for example I have a Philips Brilliance 109P4 CRT and when I hook it with my Lenovo Z50-70 Laptop (which is using Intel graphics as the main display output) tells me that my CRT is in fact DIGITAL!!?!? can you imagine an analog VGA monitor working as a digital one??waht?? plus the resolutions that are available aren't even MATCHING the original resolutions of the CRT(meaning I must use an analog CRT 4:3 monitor as a digital 16:9 LCD) RIDICULOUS!

[SLyon1]

Yo Bryce, any chance I can grab a copy of those beta drivers, even though you already got three people?

I'm really looking into this myself, and I finally managed to find this thread, after three months.

Signed up just to ask this question.

My laptop has a Chi Mei 173HGE 1080P IPS panel, which has been proven to run about 100Hz stable on pure Nvidia 'tops.

It also runs an Optimus setup between an i7-5500U/iHD 5500+GTX 950M.

With the 60Hz, all my games look... jumpier, than on my 75Hz monitor I use with my desktop, which doesn't register as 75Hz on the laptop, as relevant to the sister thread on EDID overrides.

EDIT:

One thing i forgot to mention.

I can plug in my 1080P TV, and it will let me add custom resolutions.

I'm trying to see if the TV will run 75Hz or the advertised true 120Hz (not the gimmick 120Hz flicker), but when I go to apply the resolution, it doesn't change it.

Sometimes it will flicker, but it always changes right back to 59 or 60Hz instead of trying to push the resolution.

THIS issue is what I believe to be a bug, rather than a works as intended thing like the laptop panel lock supposedly is.

I have this issue on both VGA HD15 and a rev2.0 (4K@60Hz) compliant HDMI cable.

EDIT 2:

VGA/D-SUB does work; must have broke that first time as a fluke. Still isn't playing nicely with 75 or 120Hz; resolution detection messes up on the TV.

HDMI still no dice at all.

[ABald4]

Any Chance of getting this fixed? I get massive migraines on any lcd set at 60Hz. $1300 msi laptop that makes a nice paperweight because the custom resolution tool doesn't function?

[AScis1]

Any news on this? We are still waiting at least infos..

[SBarr5]

Just wanted to pipe in and apologize for all the negative commenters on here when you are clearly just doing your job. Glad some headway is being made on this issue. As a video editor, it will be great to be able to view video at custom frame rates, especially when I'm working on a 25 or 50 project.

I would also be interested in using the beta driver if possible, although I know that might not be something you can release.

Is there any ETA for the feature yet?

Thanks!

[DCris3]

You have absolutely NO right to apologise in behalf of me and the other 'not so patient' commenters here.

You are a video editor, you should know better what you buy and what are the features you need. Intel has failed your demands and you still apologize. With this attitude we deserve what we get, incomplete, half-baked, feature broken drivers.

A lot of people use laptops as their to go pc's which they ocasionaly connect their monitor. You have 0 control of the output configuration apart from the default resolutions and refresh rates on either the laptop screen and external monitor.

But I dont know what's better for you so go on and apologize to the poor, busy Intel team. You're right, we should wait a decade for the fix

[AChen100]

Up vote.

See if Intel doesn't "see" any demand on this issue, they aren't going to do anything about it. If everyone seems to have a lousy attitude about this and seem all "oh-darling-its-fine", Intel's just going to focus other products such as their next gen products which nobody needs. Now with Zen coming up closer than ever Intel is under pressure to develop hardware AND software that ACTUALLY WORKS...

[GVasi2]

cmon Intel wake up... Don't make us wake you up

[AChen100]

I wonder why we mobile users are putting up with Intel anymore.

AMD hasn't been the best for some time, but things are turning. Take the FX-9800P, for example. And the AMD PRO A12-8800b. (7th generation A-series APUs) They are equivalent in performance to the i7-6500U, and both have a 15W TDP. Allegedly they have higher iGPU performance, but I can't confirm that personally.

When Zen comes out, I'd like to see how it compares with Kabylake and possibly Cannonlake.

[GVasi2]

Yes, I agree. Intel is ridiculous and Bryce a puppet. "a feature" and not a "bug" . HA ! So your unlocked processors is also a "feature" thats why they cost a premium.... RIGHT ? Do you think we don't understand marketing and law ?

Don't start us with the "shouting doesn't help" cause if we take you to court "it might help". MAKE IT HAPPEN FASTER.

WE are the people that buy your products and WE decide what you should make for US, why is that so hard to understand ?

Not that I didn't flash my monitor with custom EDID the moment I found out that I couldn't change my refresh rate, but that doesn't mean I can't complain for something I shouldn't have done or that someone else knows how to do that or that in fact he/she should be doing that in the first place.

And you also want us to thank you for not being Apple ? Ridiculous !!!!!

New betas fix for stupid games happen everyday, without taking months to fix and we suffer with bad resolutions and refresh rates for years and we still have to wait months for the bug to be approved then double approved then triple approved then publish then wait another month then approve again .

RIDICULOUS!!!

[JGro]

wow... so much hate, even when the issue has already been solved

[GVasi2]

Of course there is hate. We are buying things than don't work as supposed to. Intel blames the monitors , the monitors will blame the gfx cards and nothing works like it should although they now have our money.

And why do you say the issue is solved ? Do you see any new drivers ? I don't . No the issue is not solved. It will be solved when I can download the drivers and set custom resolution.

[AChen100]

Uh, I'm sorry, solved? That statement is just farcical. I don't recall any mention of a driver update.

[DB6]

^I'm impatient as well.

I ended up here after seeing this thread http://forums.blurbusters.com/viewtopic.php?f=8&t=188 Blur Busters Forums • View topic - Successful Overclock 60Hz -> 180Hz of Laptop LCD!

Not an essential piece of functionality that I need. But nevertheless something I wouldn't mind trying on my Latitude E5550, especially after getting a QNIX QX2710 to 120hz.

Can't wait to hear more about further advancements.

[kd]

Please for the love of god release this driver.

Intel is the only graphics vendor that doesn't have any custom resolution support, for years this function has been broken and it's never worked.

Some of us just want to be able to override the EDID and change the refresh rate of our display (ie overclocking it or whatever else).

We own are hardware and know the risks, so please ENABLE IT RELEASE THE DRIVER ALREADY IN A TIMELY MANNER (don't promise to and make us wait another f---ing half decade just to add a couple of text boxes and buttons that don't f--ing work)

I just want to be able to change the refresh rate, is that too much to ask intel?

Also,

There are so many laptop users that have waited for something like this.

If people (not just those randomly googling like me) knew working custom resolution support was being tested then your forums would be flooded.

Everyone who owns an AMD notebook is already good to go since CRU works, but for the vast majority of other laptop owners (including people with optimus since the iGPU is the one handling the display functions) we have nothing.

Can someone who received the beta driver PLEASE POST IT (notebook review forums, overclockers forums, anywhere else)?

Everyone is waiting for this driver, and you know intel is unlikely to ever release it.

[AChen100]

Was it just me or did everyone just receive 15 emails for margroloc's post?

oh, And +1 to margroloc's post. We're yet still waiting

[JD5]

It's been 7 month since I figured out how to flash CRUs values directly to EDID chip of monitor. By the time they invent CPU which will survive opened space vacuum I custom build spaceship and drive to Mars.

Please, send me a beta driver on Slandolyx AT ukr.net so I could change and set refresh rate without so much hassle. Will not publish it on forums if you don't want to, man.

[S5]

I would like to express my support.

I would also like to add that it is so embarassing, stressful and stupid that Intel drivers don't allow resolution upscale. E.g. I can have 1920x1080 running on my 1366x768 monitor when laptop is connected to 1920x1080 HDMI TV in clone mode, but it's impossible to achieve without TV, by implementing custom resolution in Intel's own drivers... This feature could solve a lot of problems for numerous low-res machines, since 1920x1080 upscaled is perfectly usable on 1366x768 displays.
