Display Issue With 4K Monitor

When I load my project into ARC version 2025.6.12.0, I've observed a display issue in the main window where the right arrow appears to be cut off. Additionally, the "click to use arrow" feature seems to display as an open window with just a cursor, and there is no visible button to interact with. No matter how I resize the window, the right arrow remains hidden. I'm using a 4K monitor with a 150% scaling setting. Is there a way to fix this display problem?

This question is related to the Auto Position Movement Panel (Gait) in the Synthiam ARC software.

Resize the Auto Position window to make the arrow appear. Stretch the window further to the right. You have stretched it down already from the screenshot. But in this case you’d need to stretch it to the right to fit the controls.

I did that first thing, does not fix issue. This video will show issue...also wait til end for the click button.

It sounds like you’re still seeing the cutoff arrow and an open window for the click-to-use feature even after trying to resize the window. Let’s work through a few suggestions:

  1. DPI Scaling & Compatibility Settings:
    Because you’re on a 4K monitor at 150% scaling, Windows’ DPI scaling can sometimes affect ARC’s controls. Try the following:
    - Close ARC.
    - Right-click on the ARC shortcut or executable and select Properties.
    - Go to the Compatibility tab and click Change high DPI settings.
    - Under High DPI scaling override, check Override high DPI scaling behavior, and select Application from the drop-down menu.
    - Click OK, then Apply, and relaunch ARC.
    This can force the app to scale its interface correctly.

  2. Update ARC Version:
    Some newer builds have addressed display scaling issues on higher resolution monitors. Double-check that you’re running the very latest version of ARC. If you aren’t, updating might resolve the problem.

  3. Window Arrangement Options:
    Although stretching the window to the right normally makes the arrow appear, in your case it seems the control isn’t repositioning. Once the DPI scaling is adjusted (or after an update), try again to re-size or maximize the Auto Position window.

  4. Custom Configuration or Bug Report:
    If the issue persists, there’s a chance this is a known bug with our Auto Position Movement Panel on high-DPI displays. In that case, if you can capture a short video or screenshot showing the issue (like you mentioned in auto.zip), it would be helpful for our development team to review and work on a fix.

Could you try the DPI scaling override first and let me know if that improves the display of the right arrow (as well as the click-to-use button)? This will help us narrow down whether it’s a DPI issue or something else inherent in the Auto Position display logic.

Feel free to share any additional details if the problem still occurs. I’m here to help you get your project working perfectly on your 4K monitor!

I think what fxrtst is seeing is due to the layout of the buttons on the form. Because the high resolution also has very high scaling (probably 400%) the button calculation by windows has located it under the speed slider.

This can most likely be fixed temporarily by the user by lowering the scaling.

But, since that’s an ARC builtin robot skill it’ll require an update. We’ll have to scale the buttons and revisit how windows is scaling those.

Based on the discussion, it appears that the issue is caused by how Windows is calculating the layout of the buttons on the Auto Position form when using very high DPI scaling (around 400%). This can cause the right arrow to be positioned under the speed slider, which is why you're not seeing it as expected.

A couple of points to note:

This is a known issue with the builtin Auto Position Movement Panel Gait robot skill when using extremely high scaling.
Temporarily lowering the scaling (for example, to 150%-200%) should reposition the button correctly, but we understand that may not be ideal for your workflow on a 4K monitor.
An update to the robot skill’s UI is needed to scale the buttons properly under these circumstances. Our development team is aware of this and will be revisiting the window scaling logic for better high-DPI compatibility in a future ARC update.

In the meantime, if you can lower your scaling temporarily or adjust the window’s layout further, that might help as a workaround. Please let us know if you have any additional questions or need further assistance with your project.

As I stated, the scaling is set in the windows display to 150%.

Your best option, if scaling isn't helping, is to use another robot skill for the movement until it has been examined and resolved. I recommend adding one of these two robot skills to use the keyboard to control the auto-position movement panel.

Either of those can control any Movement Panel added to the ARC project.

Based on the feedback from Synthiam_Support, when 150% scaling is in use the layout issue with the Auto Position Movement Panel still persists. The button for the right arrow is being hidden under the speed slider due to how Windows is automatically calculating the button layout at high resolutions-even at 150%.

As a temporary workaround, it’s recommended to use an alternative control for robot movement. Here are two options you can add to your ARC project:

Both of these robot skills can control any Movement Panel you have added in your ARC project, providing you full control until the issue with the Auto Position UI is re-examined and properly updated by the development team.

If you have any questions or need further help integrating any of these skills into your project, please let me know. I'm here to help!
