4k screen with scale

Asked by juan on 2018-08-03

I am using a 4k screen (3840x2160) 40 ", in windows 10 pro (64bits) and windows 7 professional (64bits)
use an intel 2500k cpu, a gpu amd rx480 8GB with the latest drivers available.
I try with java jdk 32 and 64 bits, 7, 8,9 and 10.

I use the screen in its native resolution, I also use windows scaling at 200%, because some of the programs I use need that scaling or they look very small.

The problem is, with that configuration Sikuli sees the screen as if it were 1920x1080 in some situations and 3840x2160 in others.

For example, hover sees the 1920x1080 screen and regions and image comparisons see them as 3840x2160.

that means that when detecting an image, it does not detect it, or if it detects it, when moving the mouse with hover go to anywhere, or directly tell me that the coordinates are off the screen.

for now what I'm doing is using the screen in 1920x1080 100% scale, but it bothers me a lot in some applications, because I lose a lot of sharpness, especially in fonts. at 1920x1080 work perfect.

Is there anything I can do to solve this? something to try?
Do you need more information to help me?
thanks in advance.

this is a known problem.

... but I cannot help you, since I do not have the resources (machine/Monitor) nor do I have any insight, in what is going on there.

Sorry.
