I'd like native resolution on the XG1V4 box

I'd like native resolution on the XG1V4 box

I'd like to have my TV do the upscaling and I have the XG1V4 box which does not seem to have this opiotn. What is the resolution you send to this box so I set it to that resolution and let my TV do the upscaling? 

 

Also I'd like to request that you add a feature to allow native/pass-thru resolution.

There is no 4k content delivered by the X1 system EXCEPT for Netflix and you have to pay Netlix extra for it.

What type of television: brand, model, smart?, UHD,size screen, are you using with the V4 DVR?

 

Since there is essentially no 4K coming from Comcast linear cable, leaving the box set at 720P would likely work best. Then you will have to know how to use your television's menues to provide the best video when up-scaled, and same for audio settings.

 

You may find using the television's built-in apps will work best for IPV viewing in: 1080p, 1440p, and 2160p, for now.

I've got a Sony XBR75Z9F. It's 75 inch and converts everything to 4k. My preference would be to have the v4 with an option that allows you to pass through whatever resolution the box receives without it doing any scaling/conversion.

Re: I'd like native resolution on the XG1V4 box

Thanks, I understand that feature can be used to set a desired output resolution. However I don't want the x1 box doing the scaling for output. I want my expensive TV to do the scaling (will scale it to 4K). What the X1 box lacks is the ability to passthru the stream without any scaling. My understanding is most of the channels are 720p with the locals at 1080i. I want those passed thru as is and let my TV scale it to 4K.

Re: I'd like native resolution on the XG1V4 box

If you were using an antenna (passing through no box) you get either 1080i or 720p over the air.

 

So choose 720p or 1080i, or do what most people would do.

 

Try all options and use the one that works best. Read your television's manual and find what adjustments and setting work best for your final picture. Televisions set at default are not the best picture possible depending on the provider you might be using anywhere in the world.

Re: I'd like native resolution on the XG1V4 box

For now I've selected 1080i but still would prefer to just passthru the native resolution. What happens when I watch one of those rare 4K shows. Does the x1 downconvert to 1080i and then my TV upconverts it - that would be a shame.

If any 4K shows up and you wish to watch it, just set to 4K at that time.

 

If the picture looks worse than you are used to, just go back to your original choice.

 

For electronics, "Pass through" means a device will pass through a signal when "off". I use a 2nd adjustable RF amplifier in my motor-home for OTA signals. If additional amplification is not needed, turning it "off" passes the original amplified signal through. It saves having to remove the amplifier from coaxial when not needed. The extra amplifier was designed for long coaxial cable runs in a home for cable, or satellite  use too.

Re: I'd like native resolution on the XG1V4 box

selecting 1080i destroys the advantage of 'progressive' (full image frames) in fact it degrades 720p60 by downconverting to 1080i(30) interlaced. leave the box in 1080p and upconvert from that to 4k if you wish to see upconverted image. IMO it is better to leave box in 720p and change to 4k when you are using the Netflix X1 app.

Comcast, how about a reply? There are many of us that want your box to pass through the resolution you supply to the box for each channel and let the TV upscale it.

You should be able to do that with your TV.  My TV takes a 1080 signal and upscales it to 1920.

Re: I'd like native resolution on the XG1V4 box

I think you mis-understand my issue. Let my try to expand on it. My understanding is that the box receives either 1080 or 720 depending on the channel. And some input (e.g. Netflix) can be 4k. I would like the box to pass any of these signals directly to my TV for up-scaling so I don't have figure out which resolution it is receiving for each channel and the manually set that on the box. 

 

Yes I could as I do now set everything to 1080p but that means some of the content is scaled/manipulated by the Xfinity box and my TV does a far superior job of that.

I would also like to have this!

 

With older boxes, this was available through a hidden menu.  Quality was always better for me because the TV was upscaling rather than the box.  Would be great to have that with 4K.

 

I can swear, more than 10 years ago when I first got HD Xfinity, the available HD channels were broadcasting in 1080i, with only one or two doing 720p.  This means Xfinity did something to save bandwith?  Back then the picture was beautiful and detailed compared to now.

all cable HD channels are delivered in 720p60 from HEVC source converted to mpeg4.  1080i is not same/similar to 1080p, it is a format for projection TVs and CRT based TVs not at all good/compatible for today's flat panels that only know porgressive (p) stream handling. some local channels (like NBC) are still delivered by 1080i and all local channels are in mpeg2. the 4k TV without 'zooming' would show 720p and 1080i as a rectangle in the middle of the screen taking up 1/4 or less of the screen.  you might want to go through video setup/optimization for the new 4k set top box while streaming 4k from netflix - they have some test pattern videos available. once you have that set as best you can or by using a service to professionally set up the video, then toggle the video from 720 to 4k only when watching 4k and back to 720p60 when not watching. then your set top box will be able to do the job of upscaling.
