Take it to the Apple store. They will not only help you be sure it's hardware but explain how they would get you an equivalent device for a known cost with Apple's warranty on the "repaired" iPad part. They might even be able to speculate if the case shows damage that might make a determination if it's more/less likely that you have a wiring or glass/digitizer issue.
Then you can decide if you want to buy a used iPad and try to scavenge parts or buy a new digitizer and roll the dice to guess if it's the screen or the connector or the chipset on the main board that turns the raw signals into a touch event.
Once you know your "official cost to replace" you can decide if you want a DIY project or perhaps pay someone that repairs iPads professionally to offer a repair that might be cheaper than Apple's but have less of a warranty than getting something factory made or factory refurbished.
Your probably best of if you crop the photos yourself. Here are the pixel counts that work best for each screen size:
iOS devices: display sizes
- 320×480 pixels : iPhone (1st generation), iPhone 3G, iPhone 3GS, iPod touch (1st–3rd generation)
- 640×960 pixels : iPhone 4, iPhone 4S, iPod touch (4th generation)
- 640×1136 pixels : iPhone 5/5s/5c, iPod touch (5th generation) Retina display
- 1024×768 pixels : iPad, iPad 2, iPad mini (non-retina)
- 2048×1536 pixels : iPad Air, retina iPad mini and iPad (3rd–4th generation), all of which have Retina display
Automate resizing using Automator
Automator let’s you easily crop images. See my screenshot below for explanation and just click the actions together.
You can automate resizing the photos with Automator, if you don’t demand to choose an extract of your photo.
Rember to use “crop images” with “scale before crop: Scale to Short Side”:
After finishing your workflow you could add a thousands images and let your Mac do the work. You will be prompted to select your images (see first action).
Just adapt the sizes for your corresponding device. You could also merge this into one workflow. Just duplicate the last three steps and change the suffix (_iphone5
) in action “Add text”.
Here is an example image* went through my Automator workflow.

Resizing using an application
You could use the free app Ensoul Wallpapers from the Mac App Store. This let’s you choose an image extract.
The maker of another app (deko) documents the sub-pixel shifts that parallax changes can have at http://dekoapp.com/parallax/
I hope my answer helps you with your problem concerning your image size and how to resize them. Unfortunately, I do not see an option to set a background image in Apple Configurator (Version 3.5 (289)).

This is the intended behavior and it cannot be changed. The bottom row takes on a color derived from the background itself (similar to iTunes when you expand an album).
Generally, that row will be filled with icons. Seeing it with a special background helps differentiate those apps which will show up on every page.
