Why External Monitor Has Problems But Macs Don't?

[EDLIU]

I purchased a Samsung Display(C32H711QEE) for my 17-inch, Mid 2010 MacBook Pro. The external monitor has many problems.

How come my Macs(PowerBook G3, iMac, MacBook Pro) build-in displays don't have problems like my new Samsung Display?

Thanks.

Can you give us a few examples of "many problems"?
That descirption doesn't really tell much at all.

Which interface are you using on the display, HDMI, or mini DisplayPort?
Have you tried the other interface on your Samsung display?
Did you try different cables, etc?

Have you tried the Samsung on any of your other Macs? The PowerBook G3 would be highly unlikely, but you did not give any details about what other Macs you have. Perhaps you can try the display on one of those...
[doublepost=1502808543][/doublepost]When I looked at your previous posts, I think your only real choice will be the mini DisplayPort.
You can try to verify that a cable is not part of your issue by trying a different brand cable - mini DisplayPort to mini DisplayPort.
Finally, you should try connecting your new display to some other computer that SHOULD support the connection, and should support the resolution of the display. If you don't have some kind of shop near you that would allow you to test your display, maybe a friend could be helpful with a home computer. Could be a windows PC, the Samsung won't care, as long as the interface that you try is a supported one.

I do not know how to describe the display problems in English. I googled the web and cannot find any useful information.

Any suggestion?

Thanks.

You don't know what your problem is? e.g. Black screen, shuttering, wrong resolution, wrong colours, intermittent…

Can anyone move my post to "Macs --> Notebooks --> MacBook Pro"?

Thanks.

Although this is an English-preferred site, you can post details in your own language.
With world-wide access, someone will understand what you post, enough to give you some help.

I'm trying to translate the problems to English. Please let me know the correct words for the translated display problems.

01. The system does not run smoothly
02. Delay? Lag?
03. Blinking?
04. It takes a few seconds to change to the next screen.
05. Bright Dots, Dark Dots.
06. Before showing the next screen, the entire screen becomes black.
07. Put the Safari to full screen, the system becomes dull.
08. 2/3 of the screen is showing, 1/3 of the screen is black.
09. Display screen shows flashes, like lightenings in a raining day.
10. Does not look like a WQHD(2560X1440) in resolution.
11. Does not show the vivid of colors for Samsung's Quantum Dot.
12. The build-in display card for the monitor has problems. Looking at video files it will have problems.

How come the external display has all these problems, but the internal displays for my Macs(PowerBook G3, iMac, and MacBook Pro) don't?

I use a MDP to MDP cable, which the Samsung display has been strengthened for the interface. The image and video qualities was told also have been strengthened by the build-in video card of the display.

Thanks.

Sounds like you have a bad monitor, cable, or computer.

Because they are different computers and different screens?

It could be some problem with the discrete graphics card(nvidia GeForce gt 330m?) in the mbp. When you are using the internal display the machine defaults to the internal Intel graphics to save on power unless you do something graphics intensive.

Hooking up an external monitor causes the mbp to default to the external nvidia card.

 

[EDLIU]

So you mean that the 330M may have problems? What about display motherboard and build-in video card problems?

Thanks.

Try the monitor on another Mac

Can anybody translate the display problems to the correct words? Thanks in advance.

Find out the answer to your question by posting your question in your own language.
You seem to have difficulty with getting a good understanding in English --- so, try your own language. Then, you might get the response that you want.

First, try a few steps:
Try your display on a different computer to make sure it is working properly. If you don't have another computer that you can use, then try to find a friend with a computer. It does not matter if the other computer is a Mac, or some PC. You just want to test your display to make sure it is working properly.
Have you tried a different mDP to mDP cable? The video connection can sometimes be a time to experiment, as the quality of cables, and compatibility can vary a lot.
