MP 1,1-5,1 4,1-5,1 Problem with Mojave and new monitors

[0488568]

Last week I had 1 of my 2 monitors die on me (dell 23") after about 10 years of use. So I went and purchased 2 BenQ BL2420PT.

These new monitors can go upto 2560x1440. Problem is that when I do configure them at this resolution my left monitor has problems with the fonts. They look like garbage.

So I can only use them at 1080p.

Im using a Radeon RX 560 4 GB video card.

Anyone have any ideas how to resolve this?

Also, did not find any drivers from BenQ for OSX.

What is the make and model of your card - a link would be appreciated . I'd like to see what connectors it has .

And , what interface connections do your displays have ?

You should have no problem pushing 1440p at 60 Hz with DVI or DP . HDMI is another matter .

I think its an MSI.

On the "good" monitor im using DP on the "bad" monitor im using DVI.

Thanks!

2560x1440 is the native resolution of your displays ...

Have you tried to access all available resolutions within System Preferences ?

Go to System Preferences , choose Displays , click the scaled button while holding down on the option key of your keyboard .

You'll get a lot of resolution choices , not all of them good .

See if a desirable one is an option .

That was the way I discovered that only 1080p worked right.

OK , there is a hidden Detect Displays feature in the Displays part of System Preferences .

Press the option key with this window open . Don't click anything in the window .

It will appear as a clickable button in the lower right part of the window . Click this button .

You might want to unplug and replug in your Displays to see if that handshakes them to your Mac properly .

Press the option key with this window open . Don't click anything else in the window .

It will appear as a clickable tab in the lower right part of the window .

Thanks for the help by the way.

The screen detect did nothing.

Now the crazy part.

I tried taking a screenshot of both screens so I could show you.

The "good" screen the config says for default resolution: 59,88 Hertz (NTSC)

While the bad screen has: 60 Hertz

Here comes the kicker, in the image of the "bad" screen everything looks perfect! WTF!!!!

This is nuts.

I wouldn't worry about the refresh rate being listed as just under 60 Hz - it happens to some of my hardware configurations on occasion .

I had a thought . Are you using adapter video cables ? Like Display Port to DVI . Or something like that ?

OK I switched the cables around and the same effect appeared in the other monitor.

So its its something with the card/cable/drivers.

What do you think?

Failed display cable .

Also , never use video adapter cables . There are some exceptions , like mini DisplayPort to standard Display Port in which the signal is not altered . But video adapter cables in general can be nasty things .

BTW , only Apple writes macOS graphics card drivers these days . They are always found within macOS . You don't need to download them anymore .

You are right!

It was the cable. I was using the previous monitor cable.

I just changed to the cable provided by the manufacturer and it worked!

Now how do I scale up the font, I can barely read stuff...

Thank you!
