Solution for achieving equidistant in x and y directions?

[Chamara_s_s]

Hi,

We have been using TouchGFX for our interfaces with a screen that has the following specifications (see datasheet extract below). We have noticed that in the graphics displayed on the screen, the length and width per pixels are not uniform. Upon further investigation, we found that the pixel pitch on our screen is also not uniform, as highlighted in the datasheet extract below.

This inconsistency is particularly noticeable in circular objects. The circular object here is a perfect circle but it displays a bit squished.

Is there any solution for this matter that can be resolved through device configuration settings, such as a scaling factor in the x/y directions that we can configure? or please feel free to suggest any workarounds for this issue.

Thanks,

Hello Chamara

Unfortunately there is no any scaling- mechanism available.

So basically your options are to manipulate circle images so that they look perfect round on your display or then replace your display with other type which has square pixel.

Hello JTP,

Thank you for your response. I just wanted to confirm if there are any adjustments that can be made within the device configuration before exploring other workarounds. Your assistance is greatly appreciated. Thank you again.
