My blueray dvd player isnt working because the tv resolution is set on mono 480p how do i change it back to 1080p to get my blueray to play again

You don't. The TV's resolution can't be changed. Only the signal resolution from the source can be altered.

The TV reports the resolution of the incoming signal before it is scaled. If you have a BD player you can see the effect of changing the resolution setting from 480p, to 720p, to 1080i, to 1080p 60, to 1080p 24. The last three (the 1080 resolutions) shouldn't look too different with a Blu-ray apart from movement because the native picture is 1080p 24 and the TV is simply converting it back to 1080p 24 for display.

You don't. The TV has a resolution of 1920 x 1080 pixels; so it's already 1080p. The number of pixels can't be changed.

What you're probably getting mixed up with is the TV showing the resolution of the incoming signal when you change channels or go to a different source. Standard definition from cable might be flagged as 480i. DVD might show either as 480i, or 480p, or maybe 720p or 1080i or 1080p if you have a scaling DVD player and set it appropriately. HDTV on cable or satellite will show as 1080i or possibly 720p. Blu-rays and PS3/XBox 360 or PS4/Xbox One should show as 1080p when your TV is connected.

Whatever the source signal resolution, the TV will scale it up to fill the panel area of 1920x1080 pixels. So the TV is always using all the pixels, regardless of the resolution of the source signal.

Yo don't. The TV's resolution can't be changed. Only the signal resolution from the source can be altered.

The TV is a fixed pixel device. The panel has a resolution of 1920x1080 pixels. The incoming video signal is scaled to fit that display. If the signal is 480i then it is deinterlaced to make it 480p, and then scaled up to make it 1080p. The amount of detail in the picture doesn't change. It's still a 480i image. It's just blown up to fill a 1080 panel.

The TV reports the resolution of the incoming signal before it is scaled. If you have a BD player you can see the effect of changing the resolution setting from 480p, to 720p, to 1080i, to 1080p 60, to 1080p 24. The last three (the 1080 resolutions) shouldn't look too different with a Blu-ray apart from movement because the native picture is 1080p 24 and the TV is simply converting it back to 1080p 24 for display.

960i is a funny resolution. That would be achieved by line doubling a 480i signal. But it's not one of the VESA HDTV timings. TTBOMK there's no Blu-ray or HD source that generates a 960i image. So even if you could generate it then the TV wouldn't understand what to do with it.

If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.

Hi,

I have few options for you to get the video back on HDMI:
1. Try out changing the video resolution on HDMI set up (select 480p..1080p).
2. Play NTSC disc (to get the 60Hz out from Player). If your are in US.
3. Select the TV system as AUTO/NTSC to get the 60Hz out only on HDMI.
4. if the Deep Color option is available in HDMI set up menu..set it to OFF.

Let me know if you tried all these and still no output.

After searching the owners manual I find that there is nothing mentioned about the screen resolution i.e. 480p to 1080p.

This set is capable of your desired resolution and as far as I can tell it auto selects because it senses the input video and decides which is the best setting for that source.

It's important to understand that you need 1080p video to use it at it's full capabilities. It won't give you a 1080p resolution from a VCR or a standard DVD player. You need a DVD player that is capable of producing a 1080p encoded video. Some satellite receivers are capable of that but you need to make sure you know what resolution that you are sending to the television.

Local TV stations won't usually broadcast HD at 1080p. Your best bet is to use a DVD player that is capable of that high resolution for your best picture.

Please note that what it says in the owners manual about "Resolution" has nothing to do with the 480p, 720p or 1080p signals, your set selects that automatically it will start by selecting the 1080p then goes to 720p then 420p it's dependent on the video you send to the set.

Please note the "resolution" function is actually like a "sharpness" control.

Your video input (tuner, VCR, DVD, games and etc.) is likely your problem.

You will have to change the dvd player resolution to 1080i (or change resolution for each individual disc), because:
a) there is no way to change the resolution manually on this television
b) this TV maxes at 1080i, hence negating most of the utility of using an hdmi cable (Of course, hdmi cables are much easier to hook up, less messy than component cables; so all is not lost)

For this unit and the addition of the secuity features of Blu-Ray, the 1080i you set can handle is through the component input from a DVD player or an XBOX. In the configuration menu of the PS3, change the resolution to 1080i and see if your set will reset to it. The 1080i on the Blu-Ray is only possible on the HDMI cable as far as I could find, again due to the security restriction. The Mitsu is not going to run it in 720p due to the PS3 is running component and cannot control sync to this set.
