Hi all,
I have a Dell Precision M3800 which i have connected to two DGM IPS-2701WPH LCD Monitors (native 2560x1440 60Hz). The Dell provides two video output ports 1 x mini DisplayPort and 1 x HDMI.
Both monitors will display out the native resolution while being powered off the MiniDP port. However from the HDMI port the laptop will only display to 1920x1080 and nothing higher.
Using a Apple MacBook Pro the monitors work fine using HDMI at the full 2560x1440 resolution. so i know it isnt a problem with the monitor end.
Things i have tried,
- customapp mapping a resolution to 2560x1440 at 30Hz = black screen, and anything higher (refresh rate) - i get a dialog box stating - The custom resolution exceeds the maximum bandwidth capacity.
- updated to the latest Dell video driver
- manually installed the latest Intel Video Driver
None of these have resolved the issue. below is a copy of the Intel video report, any advise would be greatly appreciated.
Thanks in advanced

Hi Bun, I noticed in the report you shared that Windows* loads a driver for a different monitor model (Boevt Terra 2760WLED).
http://forums.overclockers.co.uk/showthread.php?p=23485173 Driver for DGM IPS-2701WPH ? - Overclockers UK Forums
You may want to ask the monitor manufacturer for a correct driver.
I also suggest you trying the following:
- The latest Intel® HD Graphics drivers.
- Check with the laptop manufacturer about a BIOS update.

Hi Joe, Thanks for the suggestion on the video driver. I have tried this and in device manager it reports the driver version as Intel(R) Graphics Driver: 10.18.10.3907; which is the one I installed a week ago.
On the driver for the monitor, i think i will be out of luck as i dont think DGM has ever release a driver for any of there monitor equipment. http://www.digimate.com/en/index.asp http://www.digimate.com/en/index.asp
Either way, surely the intel should be reading the EDID value and reporting the correct selectable options to the O/S.
Cheers

Perhaps you can try escalating the case with DGM. I do not think we are getting the correct EDID since the operating system is not getting the correct monitor model.
You may also try updating Windows* and check for a possible V-BIOS update within the system BIOS.

I'm having the same problem as the original poster. I'm using the same monitor (DGM) with the same panel (boevt). Windows downloads the driver, but it's still not allowing full resolution.
However, when using Xubuntu, or other Linux distros, there is no problem with the monitor being recognised and the full resolution being made available. If it is a case of not getting the correct EDID, wouldn't the same problem be found under Linux?

What type of HDMI cable are you using? Is it a High Speed HDMI cable?
From Wikipedia on HDMI:
As of the HDMI 1.4 specification, these are the following cable types defined for HDMI in general:
- Standard HDMI Cable – up to http://en.wikipedia.org/wiki/1080i 1080i and http://en.wikipedia.org/wiki/720p 720p
- Standard HDMI Cable with Ethernet
- Automotive HDMI Cable
- High Speed HDMI Cable – http://en.wikipedia.org/wiki/1080p 1080p, http://en.wikipedia.org/wiki/4K_resolution 4K, http://en.wikipedia.org/wiki/3D_television 3D and http://en.wikipedia.org/wiki/Deep_color deep color

Hi Robert,
I am using a high speed HDMI which i brought specifically for this.

We are working to locate one of the DGM displays. With similar display that I have to test with I am not seeing the issue.
Question, if the DGM is connected only to the HDMI output does it display native resolution? If it is configured as single display in graphics properties does it display native resolution? And is your MacBook running IOS?
Thanks

Hope with this extra data a solution is found as I currently have two of these monitors side by side with different resolutions.

Hi Rob, I'm going to copy Bun's format for my own response.
Monitor (DGM) - HDMI - extend display + Laptop screen1080p Windows 7 & Windows 8.1Monitor (DGM) - HDMI - Single Display1080pWindows 7 & Windows 8.1Monitor (DGM) - HDMI - extend display + Laptop screen1440p Various Linux distributions including Debian, Ubuntu and variants of Ubuntu.Monitor (DGM) - HDMI - Single Display1440pVarious Linux distributions including Debian, Ubuntu and variants of Ubuntu.I don't have another cable to try HDMI out to DP in, or VGA out to VGA in, so unfortunately I'm not much use there. As you can see extended displays on Windows give me two resolutions of 1080p. Setting the DGM as the only monitor (which disables the laptop screen) under Windows still only gives me 1080p. However, on Linux the full 1440p is doable in both configurations.
If there's any Linux diagnostics you want me to run to see what's different between Windows and Linux let me know and I'll see what I can do.

This issue has been resolved. Please use the latest driver available here:

I am also experiencing this issue.
Unfortunately, it looks like these links are broken. When I try to download the latest HD 4600 driver by searching the Intel Download Center, i find a download for version 15.36.18.64.4156. However, this will not install on my Dell Precision M3800 as the software reports that I need to install a version directly from the manufacturer. Dell is only offering version 10.18.10.3993, which appears to be very out of date.
Please advise.

Thank you for the updated links. Unfortunately, this will not install on my system as it says it is not validated for this computer and that I should seek out a driver from Dell (the manufacturer). Dell's version does not appear to address this issue.
Any suggestions?
