Hi DarkNova, to better understand what the issue is, can you please send three screenshots, in PNG format, taken 1:1 of the display as rendered by NoMachine, TeamViewer and UltraVNC?
It would also be nice if you could send the screenshot while the display is in “Keep aspect ratio” and “Fit to window” mode, so that we can understand if it’s only a problem with the scaling algorithm.
Attach images to your reply or send to issues[at]nomachine.com.
