HD 4600 2560x1440 resolution on native 3200x1800 monitor

[JWyan]

I have a new Dell XPS 15 with a native 3200x1800 resolution. I'm trying to scale it down to 2560x1440 but windows doesn't give me that option by default. I have to go all the way down to 2048x1152 to keep the same aspect ratio. So I used the custommodeapp.exe to set a custom resolution but I get "The custom resolution exceeds the maximum bandwidth capacity" error using 60hz. I tried 59, 40, 32, and 30 aswell without luck. I read other threads about this but they were for external monitors. This is for my actual laptop screen which should work considering it's under the native resolution. Any ideas?

Can't find a solution for anything

Hi pollux,

I am sorry to hear you are having problems but let me help you.

Based on the information you have provided, it seems that your system is running an older driver version so I would like to start from there. Please download and install the latest driver that can be found here:

https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23405 https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23405 \

In case you get a notification/error message, please try the manual driver installation. Here you have the steps:

Besides updating the graphics driver, please make sure you also update the BIOS and the other drivers [provided by the computer manufacture.

I tried to download manually and it said windows has determined my drivers are up to date. I'm confused what the problem is.

[JWyan]

I've updated all my drivers and it still won't let me create a custom resolution.

[JWyan]

Still no solution. I've worked with Dell trying to solve it but they don't know how. Any clues please?

I changed the TotalDTDCount from 0 to 5 since I have 5 DTD values the last one being all 0's but that didn't help either.

I used a DTD calculator to find the DTD of 2560x1440 which is 02 3A 00 18 A1 A0 2D 50 58 2C 25 00 55 50 21 00 00 1E but that's 17 bytes and the DTD's in my registry are 19 bytes ending in the same two bytes (37 01). Im super hesitant to replace the 5th DTD value which is all 0's to this new DTD value.

Is that what I should do?

Hello pollux,

I am really sorry you are still having problems. Note that our drivers are generic drivers, what I mean to say is that are OEM drivers for Intel® products but for OEM systems or Computer Manufactures we just provide the hardware to them and they will design and create drivers specifically for their systems so they can set limitations or special configurations.

At this point since the drivers from our side are not working for your system my best recommendation is to try the driver provided by the OEM or the generic driver from Microsoft.
