Hi,

I have a Dell U2713H connected to my 15" MBP Retina and the output is just awful.

I previously had a 13 MBP Retina and the out was much much better.

This cant be right since the 15" has a better graphic card.

so it must be the settings, can someone please help me with this.

Thanks!
 
it didn't work, I try to change the settings but the colors are all just mess up, there has to be something that I'm missing.

wish there was someone out there with the same monitor and computer to help out.
 
Are you sure it's not an issue with the port/cable you are connecting it with? Do a reset on the monitor and check the cables.

I’ve had my U2713H for two weeks and it works great with my retina 15". I initially had problems with blur and fuzzy text. I used a mini displayport to thunderbolt cable. Many of the internet commenters that I read said that cable was the best to use. However, after not achieving success, I used the Dell supplied displayport to thunderbolt cable and my problems disappeared. Make sure the monitor settings are correct. Under menu on the display make sure mac (not PC) is selected, present mode select standard, and select the appropriate input source. Those were the only adjustments that I made as far as clarity is concern.

Make sure you read the instructions for the monitor if you intend to use its features. :)

Update: One more thing. In system preferences on your Mac, under display, make sure scaled is selected not best for Retina. I like 1600x900 resolution myself.

If you intend to route your external speakers through the monitor you need to make an adjustment to sound on your Mac in system preferences. Just select the monitor U2713H. Note, the monitor will only appear in system preferences when it is connected and turned on. It took me a while to figure that out.

Personally I had no problems with my Dell U2713HM even tough someone here in another thread tried to convince me otherwise. In any case there does seem to be a fix here http://embdev.net/topic/284710.

Give it a try and good luck.
 
I remember some messages months ago about certain Dell monitors being recognised as TVs instead of monitors by the rMBP, and you have to click something to tell it what's really going on. Search back a bit...

I don't know if that is the problem because my unit says TV and it is working fine. Their are several discussions about this issue on this forum. Here's the latest.

To find this info on your Mac go to menu bar, click the Apple, click about this Mac, click more information, click system report, click graphics, and highlight the Nvidia's 680M graphic card. At least that's where it is on the rMBP 15'.

thanks for the reply, I am actually using the Dell supplied display port cable to TB, thats how I have been using it the entire time.

The image is like super sharp with the 15", and it was perfect with the 13"

I adjust the sharpness on the monitor and it helped a little bit but still not as good.

when i get home tonight i will play wiht it again using your advice.
 
well i just tried the above, and it didnt work, same problem...
the image is just wayyyyy too sharp and blurry
 
i dont have a thunderbolt capable macbook but i know i have 2 mini display port to vga adapters one works perfect and looks great the other is really awful

That doesn't make any sense. Those two words are antonyms. Can you post a photo? What settings are you using? Don't bother with the sharpness setting on the display itself.

yeah i just notice that.

The screen result is just very sharp, so sharp that it is in a way kinda blurry and hard to read.
 
well here's a print screen, but i dont know if it looks the same on my screen as it does on yours.

so Im looking at the picture from my work monitor and it looks perfectly fine...

its the screen I have at home, cant find the fix :(
 
I would buy a Apple Dual Link DVI adapter and see if there is any difference. If there is then it is likely the RGB issue someone linked already. If there is no difference you can always return the adapter (buy it from Amazon).
 
There was an issue with some Dell screens going into YCC colour mode when hooked up to Macs. Open the monitor OSD and make sure it's in RGB mode.

Also 99% of "monitor issues" don't show up in printscreens. >_<

when i turn it to RGB mode, the colors is all mess up and the screen is like pink

i saw in another thread that theres a fix for this by update the driver, but I'm really new to this and i requested for help in that thread, unfortunately no one is responding :(

Changing it on the monitor doesn't change the signal it's receiving, which is why you see pink and grey. You need to get the rMBP to output RGB.

That's the thread I was looking for. They do a better job explaining it than I could. :confused:
If you can use an HDMI-DVI or Thunderbolt-DVI cable, that should fix it too.
