I have a Toshiba 40RV525U


"Picture Size" modes include: Natural, TheaterWide 1, TheaterWide 2, TheaterWide 3, Full, 4:3 HD, Native, and Dot by Dot.


Which one of these will give me 1:1 pixel map for a 1080p hdmi source?


The manual says "Dot by Dot is for VGA, SVGA, XGA, WXGA, and SXGA sources only"


The manual for this set says "If receiving a 480i (HDMI), 480p (HDMI), 720p, 1080i, or 1080p signal program, Native mode scales the video to display the entire picture within the borders of the screen (i.e. no overscanning)"


I really HATE to see that word "scales" in there. I'm wondering if this is a case of terminology becoming lax.


I have read in another Toshiba manual (42LZ196)that Native "Native Mode™ eliminates unnecessary overscan and scaling of 1080 HD signals, providing pixel for pixel image reproduction, for the cleanest possible image."


THIS is what I want. No scaling, no overscanning. Just a 1:1 pixel map. Is the Native Mode on my Toshiba 40RV525U the same as the Native Mode on the Toshiba 42LZ196?


I'm HOPING that my manual was just written up wrong. Surely Toshiba wouldn't use the same name for two entirely different features??


Thanks to anyone who knows about this.

GREAT question.


Would be nice if somebody knew the answer....

 

[oldeskooldave]

well my DVI graphics card came in, along with a DVI to HDMI cable.


I set my graphics card to 1080 and set the tv to Native Mode and as far as I can tell... the picture is pixel pefect. Just like my dell LCD monitor when set to native resolution: no strange happenings around the edges, the smallest of fonts is sharp as can be.


I have no way of knowing for sure, or being able to prove it, but I'm going to go ahead and say that Toshiba's Native Mode on the 525U series is the same as it is on the higher end sets: that is to say that it provides a 1:1 pixel map for 1080p HDMI inputs.


I'm fully satisfied.

Thanks for the update Dave!

Native is just the set's no overscan mode. For 1080i/p, it is essentially dot by dot with no scaling. For the other resolutions, it scales them to the native resolution of the set with no overscan.

I just ordered the Toshiba Regza 32" yesterday, It says that it supports 1080p at 60 or 24p, So it would have to scale that resolution cause its actually at 1366x768.

Why is it 1366x768?

Thats a question that has baffled pretty much everyone around here, Why are those panels 1366x768 instead of 1280x720p?


I guess the manufacturers decided to add more pixels to those screens so that it falls between 720p and 1080p. and the TV will just scale either two to fit its screen resolution.


You could call it 768p.

Is this just for the Regza 32?

Yes, All Regza 32" HDTV are 1366x768, However they do have a Regza 32" thats 1080p.

Since your TV is a 42" model, I found a review on Cnet for a different Regza model and it mentions, That Native Mode is designed to show every pixel of 1080i and 1080p sources without scaling or overscan.


In other words, Its a good thing when you are watching Blu-Ray movies at 1080p, Or if your watching one of the local HD channels that broadcast at 1080i, Even video games that run at 1080i will work with this mode.

i have the same model as you,native is no overscanning.if you click back and forth between native and natural you will see your gaining image on the sides ,but you lose a little height.

well thats new! last year they were not making anymore 1080p in 32''.

 

[ThrowdownMMA]

yeah i'm debating between native or natural for gaming and viewing

 

[ThrowdownMMA]

i tend to like natural cuz it fills up the whole screen without any distortions on the sides

 

[ThrowdownMMA]

ah idk. i find myself switching back and forth and just wanna leave it on one

 

[ThrowdownMMA]

i guess native's cool lol. it's true 1080p right? shows everything pixel by pixel or whatever

768 is a multiple of 128. It is a computer thing. 1366 is within a fraction of a percent away from 768 times 16/9. 768 is the next highest multiple of 128 above 720. 99.9% of the panels made today are 768x1366 or 1080x1920. There have been a few plasma 720x1280 panels in the past. Why its 768 I don't know but these are the facts.


Up to now computer widescreens have been 16:10 not 16:9. That has made using a computer monitor as a flat screen TV a problem. 768x1228. I saw a WS Compaq laptop in the paper Sunday which had a 16:9 1366x768 screen. HP has a version with NVidia and a HDMI port which can provide 1080p to an external monitor/TV.


Enjoy HD as much as you can.
