Yes, he knows and had you done a search you would have know that too: https://www.mql5.com/en/forum/68402
4K compatibility started as far back as Build 810 (if not earlier), but 940 was the Official version to be fully 4K optimised.
However, it is up to 3rd Party developers to update their Indicators and EA's to be 4K compatible.
So i just wonder why would you need 4k charts ?
I mean if your talking about watching a movie okay.... but a chart ?
He is Alain, because you posed the question to Alain, to which I replied! Was that so difficult to understand? Is your memory so short, that you no longer remember your previous post or even bothered to read up on it again?
I did not say that it is optimised for 64bit! You asked about 4K, to which I answered that since 940 it was optimised for 4K! 4K and 64bit are completely different concepts that have nothing to do with each other!
You are demonstrating classic problems of P.I.C.N.I.C., so please, before you even touch MT4, fix your PC first, fix your OS installation so that works correctly, and if you don't know how, then get a qualified IT person to do it for you!
This thread is getting nowhere and you have not supplied a single piece on tangible information in order to be helped - no screenshots of problems, no error logs, no error messages, no EventViewer logs of any problems - nothing!
All you do is complain about foolish notions, constantly misdirecting our attention toward other unsubstantiated "problems", that you never present to us, and outright just waste our time!
Would you also go to a movie theater to watch an evening of 3D EURUSD charts ?
Are you living in a cavern ? Usually when talking with people, and certainly if you are the one who is asking for answers, you are trying to be polite and respectful. It seems you are no aware of this, so my guess that you are maybe living in a cavern and forgot how to communicate positively with people.
I strongly suggest you to change your mind.
