TV shopping

Can anyone recommend a TV with these features:
- stereo analog audio output
- 1:1 mode (aka overscan disable)
- 50" give or take
- 1080p or better

A few years ago you could hardly find a TV with analog stereo audio output. Now suddenly it seems to be a common feature again. You can hook your vintage stereo rig to TVs again! Great!

Many early HDTVs had no 1:1 mode, so if you drove them from a computer, the TV would cut off the edges of the screen and resample the signal. Is this less of an issue in 2015? Have the manufacturers figured out yet that this feature costs $0 to implement and is so important it should be universal? (Please tell me that I'm five years out of the loop and that new TVs default to 1:1 mode like God intended.)

The manufacturers don't even specify if a set has 1:1 mode. I was just looking at a Vizio manual, it said something like:
Picture Mode: Selects the Picture Mode. Click here to choose Picture Mode. Use left and right arrows to select Picture Mode...
Okaaay, but what the settings are and what do they do? The TV may be HD, the documentation is still fuzzy.

What do you mean by 1:1 mode?

Why not just set your computer's video output to the TVs native resolution? - Anything else probably won't look so great anyway.

And "Picture Mode" is generally pre-set color/bright/contrast settings for various purposes... "Sports" "Theatre" "Night" are not uncommon examples.

Or sometimes contain aspect ratio/zoom settings...

Meaning the display displays exactly what is sent to it, without scaling or processing the signal in any way.

Yes exactly. This is important if you might ever want to use the TV as a monitor. (eg. if your operating system supports subpixel rendering for text, that looks awful if the pixels are resampled.)

1:1 mode is also called "overscan disable", "dot-by-dot", "full pixel", it goes by many names.

Most google search results about overscan issues are from 2010-2012. So maybe recent TVs have mostly solved this.

The Sharp Aquos lineup is a contender. Sharp has a 1:1 mode, they call it "dot by dot" mode, and it's mentioned by name in the user manual (so you can verify whether any given model has it. amazing!)

It reminds me of this wonderful article, about how audio advertisers used to assume consumers were technically-minded, and nowadays they dumb it down and keep consumers in the dark:

The dumbed-downedness is there in TV advertising too. Imagine full-page glossy-color '70s-style magazine ads for a modern LED panel TV. "Dot by dot mode ensures pixel-perfect image fidelity" and so on

Sony has an " Full Pixel" or ( 1:1 pixel mapping) option in the screen menu for General & Cinema modes and defalts to perfect Pixel ( 1:1) in Game mode also when it see's a PC or SAT input , you can use any of these modes for PC on ATSC RF coax inputs.
IOW it usually picks out the right ones from the EDIE data .


The 2015 Sony 4K 55X810C and 4K 55X850C also supprt up to HDMI > 2160p/60 YcBcr 4:4:4 . I will probably be getting the 55 X810C Sony next month for the home office /PC spot to replace a 40" 2 yr old Sony that will be re -pourposed .

Samsung should have similar settings and YbCbr 4:4:4: as should the 1080p 50 and 55 Sony 800C models .

IIRC Samsung calsl thier 1:1 pixel setting "screen fit " or "just scan" depending on the set.


The 1080p Sony 800C cant make much more than 185.3 cd/m2 luminance ( not real bright in daylight but acceptable ) ..but equal and excellent contrast at ~ 5211: 1 to the 4K X810C .

The 2160P Sony 55X810C can make 265.0 cd/m2 or NIT luminance which is decent and noticably brighter than the 800C and about the same as the 4K Samsung 55JU6500 and 1080p JU6300 which are decntly bright in daylight .

FWIW the 1080p Sony 800C is edge lit .

I've seen all thsee sets last week and the Sony X810C or Samsubng JU 6900 would be my choices along with a Samsung JU 7100 but only in the 50" or 65" VA panels for the Ju 7100 .

The 55JU7100 has an PVA ( IPS type panel) with poor blacks and contrast the other two Ju 7100 sets w/VA panels are fine

The Sony X810C and JU 6900 and JU 7100 are rear lit which can work out better than many edge lit sets at these prices.

If the TV diesent automatically set a 1:1 pixel map when it sees a PC or device requireing that in any paticuklar Picture mode /input ( some dont ) you will want an adjustment option or verification option in a pixel or screen menu or screen fit menu.

Even if you have the resolution correct or the EDIE does that for you like it should :

Some sets automatically default to the correct 1:1 pixel map to DVD/BD players ,game consoles ,extenders ( like a Roku or APTV ) and PC's from EDIE data that require that others do not and sometimes depending on the user selected picture mode like movie ,cinema ,sports etc, on a PC or game console or extender it can be wrong also .


You should usually go into a pixel menu or screen menu to check or adjust or verify it . IOW it should be verified that all your inputs /devices are correctly pixel mapped and as a rule everthing is 1:1 pixel except RF OTA and *some Cable STB* that might need " +1 " Sattelite will usually need 1:1 .

PC ,Game consoles and most other HDTV and UHD devices shoukld be 1:1 pixel mapped whereas OTA COAX RF TV will be +1. -1 isn't used any more.

You can scale your screen with a calibration scaling pattern (the right way ) or verify the pixel mapping if its wrong by a very small % your 1080p set is suddenly a 720p set it happens all the time if folks dont know about it . Sometimes you can do that for your PC *if it needs it* in the GPU /GIU control
even after you verify 1: 1 pixel mapping at the TV .

On a PC or game console ( YbcBr 4:4:4: ) or more commonly ( RGB full)b Chroma sub sampling setting is good to avoid excessive pixel maniplation and image degradation .
A decent TV should support that when it sees a PC or game console on the approriate HDMI input & picture modes .
DVD HDTV and Blue Ray are YbcBr 4:2:0 with some mastered for 4K or enhanced BD 's at 4:4:4 .

OTOH If you just e mail and web browse and do office productivity on a PC RGB limited is OK on a PC so is YbCBr 4:2:2 or 4:2:0 .



Sony calls 1:1 "perfect pixel" on some sets and "1:1" on others and Samsung calls it
"screen fit " or "just scan" depending on the set.
