Viewsonic VX2453mh-LED- Full Screen, OS 10.6.7, Mac Pro

Hi everyone,

I just bought this monitor:

http://www.viewsonic.com/products/vx2453mhled.htm

I have it connected to the DVI port of my Mac Pro (2.8 GHz Quad-Core Intel Xeon, OS 10.6.7- ATI Radeon HD 5770)- VGA out with a VGA to DVI adaptor.

The problem I'm having is that I can't get the desktop to fill my screen at 1920 x 1080. I have black bands on either side (left and right) of my screen.

Is there a fix? Do I need to use the HDMI to mini port to fill the screen?

Also, my fonts look a little ragged. I have LCD smoothing checked, but since this monitor is an LED monitor, does that make a difference?

Thanks in advance for any help!

Mac Pro, Mac OS X (10.6.7), 2.8 GHz Quad Core- Intel

Just got the same screen. And the same problem, either black borders or no menu-bar visible.

Solution: open the monitor settings with the buttons on the side of the display.

Go to INPUT SELECT and switch from AV to PC mode.

HDMI can be directly adapted from DVI. If they did not give you a DVI -> HDMI cable, your best bet would be to buy one and use it on the DVI port. Conversion from Mini DisplayPort is more complex.

You did not mention whether other displays are involved.

I tried with HDMI cable and it works perfectly. I do not see any vertical bands on the sides now.

Thank you for your help!!

To change your monitor resolutions, go to your System Preferences (in your dock, or in your Applications folder). Click on Displays under the Hardware category. The monitor's resolution should be 1920 x 1080. Change the monitor's resolution to any of the other resolutions and then change it back to 1920 x 1080. You should only have the refresh rate of 60 Hertz available. Click on it anyway. If that doesn't work, repair the Disk Permissions.

Disk Permissions are repaired with Disk Utility which is in the Utilities folder inside of the Applications folder. Select your hard drive (if you have more than one, select the one with the OS on it) and then click Repair Disk Permissions. Log out and do it again. Then restart. If that doesn't work, zap (meaning reset) the PRAM. Here's how to do that:

Good luck.

I can't remember what I did specifically, but it may help to mess around with the monitor resolution settings in System Preferences (which I did). Maybe switching the resolution back and forth "forced" the desktop to fill the full screen of the monitor. The only other thing I did was repair disk permissions, logout, repair disk permissions again and then restart. I don't know if any one of those things fixed it, but something happened and it works right now.

Good luck

Oh… and try zapping the PRAM too…

I don't have enough space of my desktop (the actual top of my desk- not the computer desktop 😁) for a second monitor.

I also don't know what I did/what happened, but all of a sudden the desktop takes up the full screen.

The only thing I can attribute it to is that I repaired Disk Permissions a couple of times.

Either way, I'm happy.

Thanks for your help!

I have the same issue with the same monitor. Two black bands on either side. Talked to ViewSonic support and talked to Apple Support. Both do not seem to have any solution. Apple is asking to contact viewsonic to see if they have an updated display profile. View Sonic is asking to contact Apple to see if there is an updated Video card driver.

Any ideas on what could have fixed it for you?
