PMP Image Quality And Viewing Angle Test

We’ve taken five players with 800 x 480 displays and tested their viewing angles and display quality using the same 5 image files.
Here’s what we thought of them.
See how the Ainol V6000HDS, the Ramos T11RK, the Onda VX545HD, the Onda VX535HD and the Nationite OS-72HR fared against each other below.

Ainol V6000HDS
4.3? screen

Viewed front on the image is bright and bold but as soon as it’s tilted you lose quality.
If it’s tilted forward the whites come to the forefront giving the effect of a photographic negative, if it’s tilted backward the black shades get darker but there’s little in the way of loss of quality.
Considering the tilt, the viewing angles from the sides are remarkably good, giving little change in contrast or colour.
As long as it’s not facing straight on this gives a good display.

Ramos T11RK
5? screen.

The cool touchscreen slide navigation wins this player some points for picture viewing from the off but it won’t cut the mustard in this test.
Despite the touchscreen working against this player in this respect as the material placed over the actual display reduces the sharpness of the just glass-fronted players such as the OS-72HR, it more than makes up for it in vibrancy and boldness of colour which is really impressive.
Viewed straight on, the pictures are bright with excellent colour and deep hues.
In terms of viewing angles the best results for images isn’t the regular straight-on view, instead being tilted back at a slight angle which allows the dark shades to come out and fulfil their full potential.
When tilted down it is awash with white but again viewing from the side gives more definition to the dark shades, producing a more rounded overall colour.

Onda VX545HD
5? screen

The 5 inch screen again produces an impressively bright image but again suffers from the black/white toning of forward and backward tilt.
Like the T11RK the best viewing angle for this seems to be looking down with it slightly angled backward (in the traditional book-reading pose).
Side viewing angles impress without much loss of colour or tone.

Onda VX535HD
4.3? screen

This screen is awesome in terms of contrast and viewing angles, falling down only when tilted forward as the image falls foul of white saturation.
Despite that one issue, the colours are full, bright and well adjusted and it delivers on just about every possible angle.

Nationite OS-72HR
4.3? screen

In terms of constant quality, the OS-72HR takes the biscuit.
The image has pin-sharp definition and depth with virtually no change at any angle.
From a personal preference I feel it could do with a touch more in the region of dark tones when viewed with at the ‘book-reading’ angle but in terms of all-round quality this is a great example.

The Verdict

From a personal point of view, I feel there are three clear ‘winners’, the T11RK, the Nationite OS-72HR and the Onda VX535HD.
They all offer great viewing angles, bold colours and excellent definition.

All players at an angle

Looks like OS-72 beat the T11Rk?

in overall viewing angles the OS-72HR wins against the above players, on color, well thats more subjective, some will find the T11RK screen a bit brighter with colors seeming to be more bleached out, while on players like the VX545 the colors are much darker, which some prefer.

Ive seen a T11RK recently, and the optimum viewing angle definitely isn't tilted back slightly. You say this 'allows the dark shades to come out' as though it is a good thing, but I would have to respectfully disagree. Even with 10 or 15° tilt, the image darkens significantly, and more importantly, all detail and contrast in those darkened areas is lost. Try it with a movie, or a standard test image, rather than one of the bundled photos.

Just my opinion though. Thanks for the comparison nevertheless.

I can also attest to that the viewing angles on the os72 are simply brilliant! It produces simply beautiful images.

Go buy now! :P

Image quality is also subjective, some people like darker images, while others prefer bright images.

How about OS-43 compare to OS-72? I'm impressed that 43 image is very sharp.

viewing on the OS43 is actually very good in deed, clarity and sharpness are not as good as the 72 but angles are excellent

OS-72HR beats the OS-43 in viewing angle, but not by that much.

Man, I've already forgotten how great the 43 is with it's crispness!

I know I'm a complete homer, but man, we're really carrying some superior players when it comes to screen quality!
