    Screen resolution auto adjustment

    Adamski

      Hi all

       

      I recently purchased a Compute Stick to run some old assistive technology software (designed for kids with special educational needs) on 55'' display. These titles are all Win 10 compatible and launch successfully... however, some of the older titles attempt to change the native resolution (1920 x 1080) to 800 x 600. On all our other computers the screen resolution adjusts automatically so the programs run full screen. The Compute Stick however will not allow the native resolution to be changed - instead the software runs in a 800 x 600 window in the middle of the screen, surrounded by black borders. I can manually scale the picture up using the Ctrl+Alt+F10 hotkey shortcut - but is there any way to disable the restriction on automatically adjusting the resolution? Hope this makes sense.

       

      Thanks in advance,
      Adam.

          Are you sure that it's the Compute Stick and not the TV? It's kind of normal for a TV signal to display in the same aspect ratio as the input and this requires blank bars on either side to display an old 4:3 image on a current 16:9 display. Picture size adjustments may result in an 800 x 600 field of pixels in the middle of a 1920 x 1080 display. Have you checked whether the TV has a setting to tell it to expect a PC signal on a given HDMI port rather than a TV signal and so enable it to be stretched over the entire screen, regardless of aspect ratio? What is the exact manufacturer and model of your TV? Do you mean to say that other computers also running Windows 10 on the same TV on the same HDMI port function differently? Can you supply images of what you see on that TV with Compute Stick input and with known good input?

            Please provide the information requested previously, that will help us to better assist you in trying to fix this problem.

            According to the technical specifications of the compute stick, it supports the 1920 x 1080 resolution as you can confirm on the following link, please check page 12:

              Many thanks for your input guys.

               

              As requested, I've taken a couple of photos to better illustrate my problem.

               

              A few facts before we get to the photos:

               

              1. The native resolution for both screens photographed below is 1920 x 1080.

              2. The software in question (Big Bang) is programmed to resize the screen resolution to 800 x 600.

              3. When the user exits the program, the native resolution should be restored.

               

              When the software is launched from a desktop computer (connected to the 55'' display via HDMI), the screen resolution is automatically changed to 800 x 600 as expected:

               

              3.jpg

               

              When the Compute Stick is connected via HDMI and the process is repeated, the resolution remains at 1920 x 1080 and the program is displayed in an 800 x 600 window in the middle of the screen:

              4.jpg

               

              I repeated the test on a Dell 22'' monitor (again connected via HDMI) and the results were the same. When launched from a conventional desktop PC, the resolution is successfully changed to 800 x 600 (as it is programmed to do):

              1.jpg

               

              When launched from the Compute Stick, the same 800 x 600 window is present whilst the resolution remains at 1920 x 1080.

              2.jpg

               

               

              I can access the scaling menu by pressing Ctrl+Alt+F11 and manually scale up, but I'd like to figure out what is preventing the software from automatically resizing the screen resolution.

               

              Thanks again,
              Adam.

                Well, that's just the darndest thing. On older LGs, there is an info button on the remote that tells you what the resolution of the input signal is. Is that how you determined the resolutions of the respective inputs? Under the Picture Size menu on the LG, is it set to 4:3 aspect ratio or Just Scan? Are the older PCs running Windows 10? Are they using Intel Graphics like the Compute Stick or a separate card with different drivers? Have you tried upgrading the set of 5 drivers that Intel provides? I have been able to change video modes successfully in Windows programs on my Compute Stick, so I can't figure out why you are seeing the difference that you are.

                  OK, I just thought of a possible explanation for the observed behavior, and I can't get to sleep until I post it. How about 8 bit color? Older hardware generally supports 8 bit color, but newer hardware often doesn't. Thus a program that tried to switch to a video mode with a palette would do so successfully on older PCs, but probably not on the Compute Stick. The failover code seems to be producing good images but neglects to switch the video mode. If the authors of the software were made aware of this issue they could probably come up with a patch pretty quick, assuming they are still in business. It seems like an easier path than trying to coerce Intel to include drivers for 8 bit color for their product. Maybe Intel could provide an answer as to whether their drivers are capable of palettized video modes more easily than I could test for the capability myself.

                    I have the same problem with my Ideacentre stick 300 (same like compute stick 1st generation with z3735f and HD Graphics (Bay Trail)) connect on Samsung Monitor and TV.

                        Cheers guys, your help is much appreciated. Unfortunately the BIOS/driver updates didn't resolve the issue (previous driver was 4364).

                         

                        I've attached the requested diagnostic info to this post.

                         

                        The software I used in these tests is Big Bang from Inclusive Technology (Big Bang | Inclusive Technology ). There are a number of other titles which product exactly the same result. If you need access to this software, the MSI can be downloaded here:  BigBang.msi - Google Drive

                         

                        The same results can also be achieved using basic screen resizing utilities such as:

                          Actually, I don't see this problem on my Compute Stick. The mode switch to 800x600 works with the EnTech utility, but the picture fills the whole screen, thus with the wrong aspect ratio. Do you have Picture Size set to 4:3 aspect ratio on your LG TV?

                              We tried to replicate the issue in our lab, and the issue was not replicated, the Intel® compute stick worked just fine, so we came to the conclusion this problem could be related to a compatibility problem between the stick and that specific program.

                                    This is not an issue with software compatibility, this is an issue with the current driver not featuring gpu display scaling.  Unlike other intel igps there is no option to "stretch" the resolution to fit the display in the intel graphics settings.  I have the same stick as the original poster and setting even the operating system resolution to anything other than the display's native resolution will create this black border effect.  There have been several issues posted on the forums here about this
