Asus VN247H vs Dell U2412M

A while ago I decided I needed one more monitor. This would make my setup total 3 monitors, and to make it look best, borders on the monitors should be as thin as possible.

So, why did I chose the Asus monitor? The reason is because of its slim frame, and as they say on their page “Stunning Full HD Performance with a Super Narrow Bezel Design”, they even show an image of how narrow it is.


Less than 10mm? Thats pretty nice, that would mean the edge from one picture on the screen to the one next to it can be less than 20mm, or is that actually true? Well, no, it isn’t really true, and still it is true. So how can it be right and wrong at the same time?

Let’s start by looking at the Dell monitor. (wow, flash really shows how dirty it is, but anyways…)

Here is what I expect when I am getting told how wide the edge is. In this case it is 17.8mm, so it is quite wide, but they never claimed it had a slim design either. So let’s see how wide it is on the Asus monitor.

Wait a minute! The picture isn’t at the edge of the monitor! But how wide is the metal frame on the monitor? My caliper says 9.4mm, but what about from the edge to the actual picture on the monitor? Here my caliper claims it is 12.2mm, so not less than 10mm… So if you got two next to each other, the picture border to picture border on the other screen, won’t be 20mm, it will more likely be 25mm. But 5mm isn’t much? That is correct, but 5mm out of 20mm is quite a lot.

So they didn’t really tell the truth about the width of the borders on the monitor, but what about the picture? Well, once again, let me start with my Dell monitor.
When I got the Dell monitor, I connected it to power and my computer, adjusted brightness, and that was about all the adjusting I never needed to do. Colors was fine, sharpness was right, black was fine, it pretty much just worked as expected out of the box, except for a little brightness adjustment needed.

So what about the Asus monitor? As you probably already guessed, I had to adjust a lot more on it. I actually had to adjust and tweak setting so much I decided to write this blog post. After a lot of tweaking, I was still no where near the colors on my Dell monitor, which can be seen on the right of these images.

As you can see, the only color looking similar is blue. Green and red both seems to lack depth, and this makes the entire picture on the monitor looking flat and unpleasant to look at.

After even more tweaking, and a google search to see what others came up, I ended with

  • Scenery: Theater Mode
  • Brightness: 80
  • Contrast: 60
  • Saturation: 60
  • Color Temp. : Warm
  • Skin Tone: Natural
  • Smart View: Off
  • Sharpness: 40
  • ASCR: On

Notice, Sharpness and ASCR is located in another menu, and you will need those. As default sharpness is so high it is difficult to read test, when using any Scenery mode which is not user defined. But using user defined makes it impossible to get correct colors.

So in the end I ended up getting a usable result, but needing a lot more work than my Dell monitor, which was set up to something usable from the factory.

I am aware of the price difference between the two monitors, and the different panels they use, but that still makes me wonder why Asus didn’t care to make some default settings that is usable, or why they decided to put sharpness control into another menu, when it is needed when you try to make the picture on the monitor bearable to look at.


After getting colors better, and getting some depth in the picture, I noticed some strange things. There was some strange bright lines around things that moved a bit too fast, and same with some color combinations, especially ones that involved green. At first I thought it was the driver messing up, or maybe my graphics card. But swapping the cables around didn’t move the problem around, it was always only my Asus monitor having the problem.

And in this video you can see the problem. I start by having the video on my Asus monitor, then drags the video to the right, over on my Dell monitor, and back and fourth a few times. The problem with the strange lines is only on the Asus monitor.
