Hi Vorpal, ty for the answer, had never tried that magnifier function, pretty cool.
Don't really wanna use it while playing and switching between my defined ranges though.
Not sure why but flopzilla does work (and everything else seems to work fine too with that resolution).
Here is how equilab looks at the moment (not sure I'm allowed to post this link, feel free to delete it obv)
edit : ah, just realised you didn't understand my first post, probably because I didn't include an image, hopefully with the link you can see that my problem is not "the whole thing looks too small because of the resolution", but "it doesn't look as usual at all (card matrix takes much less space than what it should)"
