Make a new window repeat the image?

Question

I have an image that I want to tile seamlessly. So I do the offset-thing and clone it. What I want to do now is to open a new window with the same image (Window > Arrange > New Window) for filename.ext and then tile the windows (Arrange > Tile), but then also make the new window to repeat the image so that I can see the edits I make reflect in the repeated image so I can get rid of unwanted patterns. I hope I'm not too vague about my question! Thanks!

Thank you for your answers! I didn't quite get it to work the way I wanted though.
Can I somehow get my left window to show my image in a non-tiled state so that I can edit it while my right window shows the same image but tiled and zoomed out and updates when I make the edits in my left window? It's a bit of a pain in the *** to edit my image, then copy it and pasting it in an array. Then going back and editing, array again. This is a hassle even with an action. There's maybe other texturing applications for this kind of workflow but I thought I was so close with the New Window-feature in PS
For the updating part you can use smart objects. There is one time setup that is more involved but then you can use this as a template for any future work.
I just did that myself and described the steps:
Create a canvas with a size that will fit perfectly many squares for example 1000 x 1000 to fit 100 squares with the size 100 x 100.
On a new layer at the top left corner create a 100 x 100 square with any color or image.
Right click on the layer with the square in the layer's palette and choose Convert to Smart Object.
Hold Alt and drag the layer on top of itself 9 times to have total of 10 copies of the layer.
On the canvas, make sure there is no selection, and with the Move tool drag one of the overlapping squares snapping it to the top right of the canvas (this is easy if Snap to Document Bounds is checked in the View > Snap to menu).
In the layers palette Shift click the first and last layers to select all layers with the square.
Make sure the Move tool is selected and in its options at the top of the screen click the "Distribute Horizontal Centers" button (the third from the right side).
While all layers are still selected in the layers's palette, press Ctrl + G to group them.
Duplicate  and distribute the group vertically in the same way you duplicated the squares but using "Distribute Vertical Centers" button instead. However, Alt+ drag a group doesn't work on a document with nothing but a single group, and I had to duplicate the first group by right clicking on it and choosing Duplicate. Then you can Alt + drag and drop between Groups.
If you whish, while all groups are selected press Ctrl + Shift + Group, to ungroup and then Ctrl + Group to have all squares organized in one group and that's  basically it with the initial setup.
Now edit a tile and update the image.
In the layer's palette, double click the icon of any of the smart layers with a square and this will open the square in its own window.
Change, create or paste new image on the image of that window and when you Save this will update all tiles in the other window.
Also in case you don't know, when you are editing the square of the smart layer, you can use Filters > Others > Offset with Horizontal and Vertical set to 50 pixels and for the Undefined Areas, check Wrap Around. to help you with creating a seamless tile. It creates seamless borders and all you have to do is eliminate the seams in the middle with the cloning or painting tools.
