[BUG] The screen resolution that is displayed on the experiment window is varying from the original screen resolution

[natrayank]

Description:
As part of our experiment, we are doing the trials with different screen resolutions. One of such resolution is 1024x540.
When the screen resolution is set to 1024x540 and run the experiment, we see the resolution is displayed as 1025x541 pixel screen, varying 1 pixel from the original screen resolution.

Steps to reproduce:

1. Set the screen resolution to 1024x540.
2. Run the EasyEye experiment.
3. Observe that the screen resolution is displayed as 1025x541 in the experiment window (chrome window).

Expected behavior:
The resolution should match with the configured screen resolution.
