And now of to the bleeding of the LCD panel of the Acer GD245HQ. The above image is taken in a dark environment with the display showing a completely black image with a camera set a very high ISO and afterwards the image has been processed with an image editor just to enhance the visibility of the bleeding. In reality there is not that much light passing trough the LCD panel from the backlight, but you can clearly see that the most light bleeding is coming from the left side of the panel, some from the top and just a bit from the right and bottom parts of the screen.
Now, don’t think that there is no bleeding on the first generation of 120Hz displays, there is as there is on a lot of other monitors. On the picture above you can see that the ViewSonic display has the most bleeding coming from the bottom part of the screen and some from the left top. This picture comparing the Acer and ViewSonic displays next to each other has not been enhanced in an image editor, just shot with high ISO settings on the camera. As you can see the light bleeding here is less apparent and it is still more visible than what you’ll probably see with a naked eye directly looking at the display. In order to get more uniform backlight and less bleeding we’ll have to wait for the first 3D-capable displays to come out that use LEDs for backlight, but this also does not guarantee better results… it still depends on how good the implementation is.
As with the previous generation of 120Hz 3D-ready displays the Acer GD245HQ is also using a fast response TN panel with 2ms response rate for the pixels compared to 3ms (for 3D mode) in the first generation. As a direct result of this we can expect to have less ghosting and this is true, the ghosting is actually less as you can see on the image above. It is taken trough one of the lenses of the 3D Vision glasses in order to show you how much from the second image (the one for the other eye) is actually visible and thus creating the ghosting effect. Look at the center part of the pictures as some of the outer parts are not covered by the shutters lens because of it being too small for the camera lens. The important thing is that the ghosting is less, making it more comfortable to enjoy 3D content without annoying “shadows” lurking around some objects on the screen, or so it seems…
I’ve noticed something else you can see on the pictures above – the weird red/green ghosting that rarely appears on some images, it is probably related to some specific colors present. The both Ghosting comparison images were made from the game Tomb Raider Underworld on Lara’s boar before going underwater, but there are some other games and scenes where you can see the same strange ghosting. I’ve also seen it present for a brief moment on some videos, but I believe that this is something related to software issues and thus can lets say be fixed with a driver update for 3D vision for example. The above images are sent to Nvidia and lets see if they can figure out what is the issue and provide us with a fix, but as I said the above issue is rarely seen and you might not even notice it if you are not playing enough attention.
Fehler können per update verbessert, werden. Trotzdem ist er sein Geld allemal wert, aber egal.
