another custom resolution exceeds maximum bandwidth

HAnth — Wed, 05 Sep 2018 13:13:14 GMT

Hello

I have a laptop with an intel 630 and nvidia GPU. I want to have my internal screen at 1920 x 1080 @ 50Hz (for video playback in europe, I need all outputs to be in 50Hz). Now when I switch in the BIOS to the nvidia GPU, there is no issue (intel GPU is then bypassed). In the nvidia settings, I can select whatever custom resolution, at whatever refresh rate, I want, this works. When I want to try this with the Intel GPU enabled, I get the famous "custom resolution exceeds maximum bandwidth". I did already a lot of research on this community and google, but nothing very recent, it seems an older bug. However I did update of course the 630 to the latest driver.

Any suggestions? Thanks.

Hello, Hans_A. Thank you very much for joining this Community.

Firstly, It is worth to mention that allowing Custom Resolutions through the Intel® HD Graphics controller will depend on the Original Equipment Manufacturer (OEM) of your system (cf. https://www.intel.com/content/www/us/en/support/articles/000005540/graphics-drivers.html Custom Resolutions and Modes for Intel® Graphics Drivers).

At this point I recommend you to install the latest drivers provided by your OEM and, double check with them if this feature is blocked/limited on your system. If it is not blocked, they can let you know how to correctly set your custom resolution.

In addition, you can download the latest generic drivers for your system here: https://downloadcenter.intel.com/product/98909/Intel-HD-Graphics-630 https://downloadcenter.intel.com/product/98909/Intel-HD-Graphics-630

Please be aware that the driver I am sharing with you is a generic driver from Intel® and some features of it might not be available for your machine, we always recommend verifying if there is any update with the manufacturer of the computer. Nevertheless, we can try to perform this troubleshooting step.

Hi Antony

Thank you for your answer.

My computer is a custom build laptop (Clevo laptop frame, like the ones BTO uses f.e.), so no OEM drivers available (or needed). And as I said in my original post, I did install the latest generic driver with the intel software update tool.

Included you will find a systom log created with intels SSU.

Hello, Hans_A. Thank you for your response.

As previously mentioned, there can be a limitation by the OEM so I recommend you to get in touch with Clevo* Support so they can provide you with the correct instructions of how to achieve the customer resolution that you are looking for.

Hi Antony,
I am trying to add a custom resolution because the refresh rate I would like to have is not in the windows dropdown list.
I am using a Surface Pro 3 with the 4th Gen Intel® Core™ i7-4650U

And with Intel® HD Graphics 5000

My TV Supports 4K at 60 Hz.
I am using an HDMI cable with 4K at 60Hz support.
And am using a Mini Display port to HDMI adapter supporting Display Port 1.2, also supporting 4K at 60 Hz.

I have tested this cable setup and TV and have been able to achieve the 4K at 60Hz using my laptop which has a mini display port.

Using the intel control panel I was able to add a custom resolution:
3840 x 2180, 38Hz P.
But when I try to go any higher than 38Hz P, I get the:
"The custom resolution exceeds the maximum bandwidth capacity."

Message

I am pasting my system config values from the intel control panel for extra details

Can you please help me out?

It is unclear to me why, since the IHDG 5000 supports DisplayPort 1.2a, but ARK and the U Processor Datasheet both indicate that the maximum resolution supported at 60Hz is 3200x2000.

I could do the math myself, but your guesstimate of the maximum frequency for a 4K monitor sounds reasonable enough, but you will likely never achieve this because most monitors will not negotiate to discrete, "in between" frequencies.

I just went and ran a couple of tests with some Intel NUCs. The D54250WYH, with its Core i5-4250U processor, will only support 4K@30Hz. On the other hand, the NUC5i5RYH, with its Core i5-5250U processor and using the same mDP-to-HDMI adapter, has no problem supporting 4K@60Hz.

Hi @LewisM,

Did n.Scott.Pearson's reply help you? I saw that you @mentioned "idata" which stands for "Intel data" - it's from when we moved content a few years ago from users that no longer have accounts, but we wanted to retain the content.

Thanks

Hi Scott,

Thanks very much for taking the time to test and help me troubleshoot.

My source for the capabilities on what the SP3 should be able to output on this mini display port channel was:

https://support.microsoft.com/en-ca/help/4023496/surface-troubleshoot-connecting-to-a-second-screen

Per their Table the i7 equipped models with the HD5000 embedded gfx should get to:

Surface Pro 3

60 Hz

3840 x 2160

I've actually managed to bump up to an awkward 38Hz using Intel's own custom resolution tool in their control panel.
But if I try to hit anything above 38 Hz P I get the ....Maximum bandwidth error..

Also to note, when I use my SP3 like this I disable the primary display and output only onto the Monitor / TV(TCLR617CA) which, does 60Hz on my other devices at that resolution, naively.

Hello Mary,
Okay noted. Thanks for that info from your side 🙂

Actually, no this new information, albeit helpful - hasn't yet resolved my issue.

Any help you can offer will be appreciated!
