SWTOR monitor HZ issues

So a few weeks ago I've received a new monitor since my old one broke and despite a few issues it works very well, however when I attempt to run SWTOR on fullscreen (windowed) or when I try to alt-tab while using fullscreen a message in the monitor appears saying "Out of scale 144 HZ/170 HZ". I've set the HZ rate to 60, which is this montior's refresh rate. The game works fine on fullscreen and windowed however as I said if I alt-tab while on fullscreen to another program, like Discord for instance, that message will appear and if I alt-tab again to the game it'll be "fine". I've also tried multiple times setting the refresh rate to 60 and my monitor's resolution while changing to fullscreen (windowed) but that message "out of scale" still appears regardless. I even went as far as saying the scale should be determined by my own settings and not programs' in the nvidia control panel but it still shows the same message whenever I alt-tab on fullscreen or change to the full screen (windowed). I've tried finding a fix for it online but couldn't find anything, does anyone know a fix for this? It only happens in SWTOR.

Some information that might be relevant:
Monitor is a LG 19M37AA-B
GPU is a GTX 550 Ti 
I use an DVI-I to VGA adapter on the back of the GPU as the monitor has only a VGA entrance and cable. 
Also a picture of the message that appears, the translation as I've mentioned is "Out of Scale".
