What do you use to focus? I've been using the letters on the epson menu but I'm not sure how sharp those letters should be. I do see some edges that don't look 100% sharp but maybe that is just the menu? Example pic below. Any thoughts / advice is much appreciated.
Convergence is a measure of how well the 3 separate elements of the image produced by the physically separate red, green and blue LCD panels come together as one (or not).
Issues can be caused by bad alignment in the optical path (which isn't common), and by the physical alignment of the LCD panels being off a little from each other (which is quite common).
The symptoms are a visible separation of the green, blue or red elements of colour.
If the convergence is too bad, you will be able to see lines of the separated colours around the edges of objects.
If the convergence is good enough, at normal viewing distance your eyes and brain will automatically combine the colours into what you are supposed to be seeing and all is well.
Symptoms appear worse the larger the projection/zoom applied and the closer the viewer is to the projected image.
The Epsons allow the LCD alignment element of convergence to be adjusted by scaling the image to the red and/or blue LCD panel.
As this is a software based, pixel destructive process, it should be avoided if possible.
From your picture it looks as if the green panel is slightly to the left of the blue and red panels.
The symptom is that slight look of 3D embossed text.
BUT it doesn't look like particularly bad alignment IMO - it isn't off by an entire pixel or more for example.
I don't think I would bother applying the LCD alignment to it but you can always give it a try and turn it off if you don't like the result.
Best advice is not to get obsessed with the LCD alignment, particularly if you don't percieve issues at close to viewing distance, as it can become soul destroying thinking about it too much!
