NEW YORK (TheStreet) -- Just how good is the Retina Display on the popular, new Apple (AAP) - Get ReportL iPad mini? According to one new survey, it's not as good as its competition.

According to the experts at DisplayMate Technologies, a company specializing in the calibration and testing of scientific displays, the 8-inch touchscreen on Apple's new iPad mini Retina Display tablet was not as good as those found on Amazon's (AMZN) - Get Report Kindle Fire HDX 7 or Google's (GOOG) - Get Report latest Nexus 7.

The company has published the results of the three tablet "shoot-out" on its Web site.

Testing consisted of measuring display parameters such as brightness, sharpness, factory calibration, color accuracy, viewing angles and power efficiency. Reviewers liked all three tablets, saying all showed innovative designs. They really liked the screen on the new Kindle Fire HDX and praised the Nexus 7's display. And while the new iPad mini did lead in some categories, testers gave it third place overall because of what it called Apple's "incredibly poor planning." 

DisplayMate' survey was titled: "Two Very Special Tablet Displays and One Disappointment."

"The iPad mini with Retina Display unfortunately comes in with a distant 3rd place finish behind the innovative displays on the Kindle Fire HDX 7 and new Nexus 7 because it still has the same small 63 percent Color Gamut as the original iPad mini and even older iPad 2. That is inexcusable for a current generation premium Tablet."

Color Gamut problems are seen as color errors on your screen. Testers believe Apple's choice of screen technologies in the new iPad mini has resulted in "both product shortages and inferior products."

As for the future, experts believe tablets could have curved screens or utilize OLED (organic LED) technology currently being used on a number of top-of-the-line TV displays. We could even see tablets with super-high density screens which will provide a 30% to 40% increase in overall sharpness.
