    Cannot get anything higher than 1080P out of Toshiba HDMI port

    AdamO

      Hi all,

       

      Hoping for some help- I've picked up a Toshiba P75-A7200 laptop, and the specs state that the HDMI port will support up to 4K out.  The unit has Intel 4600HD graphics, so that supports 4K also.

       

      I've got a ViewSonic VP2770-LED monitor (1440P) and would like to run it at its native resolution of 1440P.

       

      I have tried three different HDMI cables, each claiming 1.4a support.  The monitor works great at 1440P via both dual-link DVI and DisplayPort (neither of which the Toshiba has).

       

      I've tried the latest Toshiba display drivers, the latest Intel display drivers, Windows 7x64, Windows 8, and Windows 8.1 pro, with no success.

       

      When I try to enter 2560*1440, 32-bit, at 30, 40, 50, or 60Hz, (using the CustomModeApp utility) I get  'resolution selected exceeds maximum bandwidth' error.  Based on the 4K support, I shouldn't be anywhere near the bandwidth limit.


      Any ideas?  I'm stumped.

          Try different timings. And, IIRC either 2560x1440 or 2560x1600 is the max resolution for Intel HD 4000. To get that resolution, put 2560x1440 / 2560x1600, choose CVT-RB for the timing and for refresh rate, try anywhere between 55-60 Hz. If for whatever reason you want to use GTF timing, you can only go up to 30 Hz. If that doesn't work you can try rolling back to a driver from January 2013 or before since custom resolutions were better supported back then.

           

          On a side note, if you can't figure this out and just want high resolutions for gaming, you can always use SoftTH, which was intended for those with multi display setups, but it also allows you to indirectly downsample as well (note: this is the ONLY way to downsample if you're on an optimus setup with hd 4000). All you need to do to install is copy the d3d9.dll from either the x64 or x32 folder depending on if the 3d application is 32 bit or 64 bit (operating system bit version does not matter here) and you paste it into the same folder where the .exe file is located. Sometimes you have to put it in a "data" or "bin" folder (like you do for Dota 2). Start the application once and if it's in the right place you should get a message. Close the app, go to the folder where u put it, edit the .config file so that

          renderResolution=WxH (this is the resolution you want)

          [...]

          [head_primary]

          sourceRect=0,0,W,H (should be the same as above, but different syntax)

          screenMode=<insert desktop / "native" resolution>

           

          As for download locations I'll let you google that yourself since I don't know the rules of the Intel forums yet regarding links. GL

            I have the Intel 4600HD, not 4000 - so has up to 4K support (3840*2160).  I have tried the CustomModeApp feature, and tried to enter the resolutions manually, using CVT-RB, but when I enter the resolution desired, I get the 'maximum bandwidth exceeded' error.

             

            I'm not gaming- just running office productivity apps, so don't care about the ultra-high refresh rates.

              Hi AdamO,

               

              As you say the Intel® HD 4600 supports 4k resolutions but this depend on the monitor capabilities. Sometimes the HDMI and the onboard graphics controller support this resolution but the monitor is not capable of running the desired resolution.

               

              I recommend you checking the graphics report under the Support Monitor Modes so that you can confirm if the monitor can handle it.

               

              How to get the graphics report?

                Thanks, Kevin- I'll run the report when I get home, but absolutely certain the monitor runs 1440P, as I've run it via a Dual-Link DVI connection with my old laptop, and now via DisplayPort via an external USB3.0 to DisplayPort adapter.  No reason it shouldn't run it through HDMI, as the laptop and monitor both feature HDMI 1.4 support.

                  Here's the system info- VP2770-LED is currently connected via a Startech USB3.0 to DisplayPort adapter, running at 2560*1440- but that doesn't seem to be reflected on the report, rather only shows the max resolution of the display of my laptop.  Does the EDID info provide any more info?

                    It seems that sine you are using adapters, the information about the second monitor is not being detected. Is there any possibility to use a direct connection from the laptop to the monitor?

                      Now I know 100% that it's not my monitor.  I tried plugging in a display that I have seen working with my own eyes, at 1440P over HDMI on a different computer.  Same thing.  When I type in the resolution that I want, I get the 'resolution exceeds maximum bandwidth' error message.

                       

                      Is there a specific driver that is known to work at 1440P+ under Windows7 x64?

                        Our drivers are capable to display that resolution. Have you tried another HDMI cable or testing direct connection (no adapters)?

                          I'm experiencing a similar issue. Im using an MSI Z97S Krait Edition motherboard with a i5 4690k purchased as a bundle from newegg. I have a Dell 3007WFP monitor which is capable of resolutions up to 2560x1600@60hz. I have never had an issue with this screen and have used it on a variety of system configurations. However, I can't seem to kick the resolution up any higher than 1280x800. I am about to swap out an older i5 3570k to see if it is a motherboard issue, but I seem to doubt it. I have the most current bios A3 along with win8.1 enterprise...(all patches, firmwares, bioses, drivers) that exist installed and working properly. Here is dumb of the intel information center as listed in the reply above. I hope someone figures this out...when i dumped this report i had an HDMI adapter hooked up because i was getting the same result with the DVI-D cable. Same result either way. The cable is good! Tested! Adapter works fine on other displays as well, Tested and good!
