This is a Windows issue, not an MT4 issue.
Appearance and Personalization
It seems the only solution is to buy a 55-65" 4K TELEVISION. On that one you can see all the numbers and info you want.Just think of it: putting 4K resolution on the same 22-24" monitor where the good old 1920x1080 was before will result much smaller pixel sizes and if the same amount of pixels are drawing a number or letter, then these will me much smaller, too. It's pure physics.
Also, if you change to a lower resolution or make bigger letters in windows settings (or ask for bigger letters from MT4 developers), then you're at where you would be with a 1920x1080 monitor, so these are pointless moves.
Sounds funny or scary, but the solution is to buy that $1500-$3500 big screen 4K TV instead of the smaller sized monitor.
Btw. I don't know if I want to look at my account blown on a 65" screen... :DDD
Don, my monitor is large and it does not help at all. He is 41 inches. Soon my friends will you have this new technology within reach and you will remember me. Analyse chart with a 4K resolution is infinitely better. When you do this, they will never want to go back.
So what is your 55" 4k TV if it isn't LED or LCD?
I thought I read that one of the later builds was addressing the resolution issue, but I'm not sure about that.
However, the manifest file fix should still work - have a search for it and see how you get on.
Metatrader 920 still doesn't seem to work well with hi res displays. The Charts are ok, but the market watch window doesn't remember changes to the windows scaling after a reboot.
As mentioned by honest_knave above, Metatrader scales better with high res displays if you use a manifest file...
