Do I need 1:1 pixel mapping?

Rackerz · 18 Jul 2013 at 13:41

I'm looking at getting a Sony Bravia KDL-32V4000 from eBay.

It does not have 1:1 pixel mapping via HDMI and it only does pixel mapping via VGA which my graphics card does not have (AMD 7950).

I know I am able to set a custom resolution to match the TV which I believe is 1366x768 with my card, but even so I am guessing I will still have black borders as there is no pixel mapping?

Can anyone confirm that this is correct?

Thank you

When I used to have an old 1366x768 Polaroid TV - I just had to set the resolution in Windows to 1360x768 and it filled the screen.

I think the only trouble with that would be that the picture wouldn't be very sharp as its not native?

The picture was perfectly sharp as that was the native resolution (minus the 6 pixels). It just seems to be the way.

Why this particular TV?

It is very close to me so I can pick it up for a good price.

Surely you'd be better with something that suited your needs better rather than just grabbing it because it's close by? Find a second hand model that pixel maps and get that instead!

no, 1:1 pixel mapping is what would give it the black boarders if you fed it with anything lower than native. Without it, the picture gets stretched to fill.

In your case, 1360x768 would be stretched to 1366x768. A whole 3 pixels on either size. It'll be fine

The biggest problem you might have is if the tv doesnt support 136x/768 over hdmi.

Surely you're better off for lots of reasons getting something that just does full HD, then you won't have any of these issues?

Just my opinion

I echo the above. I would opt for a 1080p set that supports 1:1 pixel mapping. I know this doesn't answer your question but long term it's the easiest, best quality option.

The Sony Bravia engine calls 1:1 pixel mapping 'full pixel'. I have a 40W4000 and it does have this option - though it's a pain to find each time I need it. A post in this forum (http://www.dtvforum.info/index.php?showtopic=68323&st=25) seems to suggest that the 32V4000 also has the full pixel option.
