The problem with my NEC 68T90 TV is that the screen resolution is not correct. At 4:3 ratio, I can't see the sides of any video or TV program that I'm watching. Is there a problem with the hardware?

The 68T90 is not an HDTV, and does not have an "Aspect" button on the remote. This is a normal SDTV (standard def) TV, seemingly made for European markets. Owners Manual

In the TV menu, there is this:
FORMAT
Picture format selection.
Select picture format between :
- 4/3: normal size
- 16/9: 16/9 size
- Zoom : expanded picture

In "Normal size" mode, with standard 4:3 video source images, you will always lose some of all edges of the image, due to what's called "overscan". This is an ancient process that causes a small amount of the original picture (typ. 2-3%) to be lost. In the early days of analog TV's, this was good, as it prevented the edge of the scan lines from being seen, which would look bad.

With the advent of HDTV, all signals are broadcast and received in digital, and is therefore totally predictable as to what will be seen... you will rarely lose even 0.5% of the image on a good HDTV.

However, having said all of that, if you are losing a significant portion of the left/right sides of the image, your horizontal deflection circuits may have gone bad. Watch for a commercial with a large circle, if it's significantly "out of round", then yes, you have "hardware" problems.

Try the aspect button on your remote, or if you have this hooked up to a cable or satellite converter, there are screen resolution preferences, you can change the screen resolution here, go the the menu portion and look for video/audio field

Only able to receive small pictures on certain channels broadcasting some older programs.adverts and most programs are ok,but selected few are not?


Most television advertising and broadcasts today are in 16:9 aspect ratio. This is why they seem alright. However, older TV shows will still show up in their native 4:3 ratio since they were recorded that way. You may be able to force them to 16:9 ratio, but although they will now be full screen, their images will be distorted in the horizontal plane. Most TVs are designed to auto-adjust to the 4:3 resolution to prevent this distortion.

Widen the screen on Westinghouse tv


Screens are controlled by ASPECT RATIO.
Monitors can have 4:3 16:9 and 16:10 ratios.

You are doing 1 of 3 things.
  1. You have a regular monitor and the tv and are duplicating the screen.
  2. You have a regular monitor and the TV and are extending the screen.
  3. You have just the tv connected.
Your video card has to have a screen resolution that meets the tv's ratio to have the tv take the full screen.

If your configuration is 1. the tv will only match the monitor resolution, so if you change the screen resolution, you may get bars on the monitor, and the tv will go wide screen.

if your configuration is 2. the tv is controlled independently and you can select it to change its resolution to an appropriate aspect resolution. *this requires that your video card gives you the correct screen resolution for your tv. not all displays will work.

If your configuration is 3. the tv is the only resolution that is being pushed and just adjust the resolution til the screen is filled in.

To adjust the screen resolution, right click on the desktop where there isnt an icon and select either Properties (windows xp) or Screen Resolution (windows vista, 7 and 8).

if you have 2 screens press the identify button and it will put a number on each screen. click the appropriate screen and go to the resolution dropdown below. Change, apply and if it doesn't look right, revert and try a different setting. if you try them all and it won't take up the full screen, then the video card can't push the video resolution your monitor wants.

I connected my media center PC to my new Sanyo DP50740 50" Plasma Television using the PC input on the back of the television. The instructions say that it supports 1360X768 with a 16:9 aspect ration...


No,13060 resolutions will not support by some tv correctly,will shift whole picture about to 6 inches to the right.That why,must use the PC Control panel to adjust to 1024 for the video to center.For the wide aspect 16:9 ratio,just find another aspect ratio to for expandsion to fit the entire screen.

Picture is stretched on wide screen a circle looks egg shape


Hello
This is an issue because most television programming is produced in a 4:3 aspect ratio. The minority of programming is high definition, which is produced in a 16:9 aspect ratio. Because televisions are made in either a standard (4:3) or widescreen (16:9) format, there is always a conflict with an image being stretched vertically or horizontally. In the case of widescreen televisions, the stretching is horizontal.
Picture Modes
Luckily, most if not all widescreen televisions have a picture mode that allows the user to toggle between a wide (16:9) and standard (4:3) mode. This means that a person can watch non-HD programming in the 4:3 picture mode, and then go to widescreen when watching HD programming. Some TVs have a picture mode that will automatically adjust to the correct aspect ratio. Other people will watch all programming in the wide picture mode, and learn to adjust to watching a stretched picture.
A stretched picture is when a 4:3 image is pulled on the sides to fill the entire screen. People and images end up looking fatter/wider and shorter.
So, what's the big deal?
Some people don't like a 4:3 picture stretched or distorted because it does reduce the overall visual and picture quality. Some people don't like the bars on the side of the screen when a widescreen is in a standard (4:3) picture mode because it looks different.
Solution
There is no fix-all solution for this issue, unless you own a TV that will automatically adjust to the intended aspect ratio. The stretching of the picture is a side-effect, the price we are paying for the better resolution that is digital and high definition. This is definitely something to consider when buying a television, but keep in mind that there is no right or wrong within this issue. It is just the way it is, and there is no way around it unless you buy a 4:3 aspect ratio television.
Hope these lines will clear the issue, if so do rate the solution

Cannot change aspect ratio when im playing a game it cuts off part of the screen


Normal aspect ratio is 4:3, and the wide aspect ratio is 16:9. If you play a game meant for 4:3 and you change the TVs aspect ratio to 16:9; part of the picture will be cut off. It is not the fault of the TV.

The image leaves about 2.5 inches not used on each side of the monitor.


Hello,

The bands are caused by the monitor displaying a picture that is not the correct resolution. This model has a native resolution of 1920 x 1080 according to LG - see http://www.pcworld.com/reviews/product/124873/review/w2353vpf.html#specs When you have your video card set to a different resolution that this the monitor tries to adjust the display to best fit the screen. The native or default resolution is 16:9 or wide-screen and if you have the video card displaying at 4:3 then you will have the blank bars displayed. Go to display properties and change your resolution to one that is 16:9 ratio and the bars should fill out.

I hope this helps, if so please rate our solution.

NEC multiSync 1700V as external monitor for Notebook Toshiba U205, Operating System Window Vista Home Premium. It displays only part (80%) of the picture compared with notebook's monitor.


Hi, if the 17 inch lcd screen is not a widescreen then the problem with the screen is possibly nothing more than the aspect ratio or resolution, which ever way you wanna look at it. All laptops have a widescreen type of ratio, so you will have to be either willing to change the resolution when you switch screens or setup different profiles, which you should beable to do through control panel, appearance and then personalization, you will then have access to it.

How can I make the picture size fit the screen? I loose picture around the edges. Seems like it is displaying at a larger size


The issue your having is aspect ratio. Some programs and commercials are broadcasting in a higher resolution so some fill the screen and some have black bars top and bottom. I suggest searching "aspect ratio for video". It would take me all night to type it out. But you need to know how the different resolutions change the size of your image. Also in the TV's menu you should see an aspect ratio option. Try the different settings to see if you can find the best.

Screen resolution


From the Console Settings screen in the System area of the Xbox Dashboard, you can configure the video output of your Xbox 360 console.

Change your display output settings from this screen. Display settings include screen resolution and screen dimension (or aspect ratio, either standard or widescreen).


In some cases you can select an "Optimal Resolution" button, which appears only when Xbox supports the native resolution of the TV or monitor and automatically applies the best setting but that might not work with your tv.

If you are using VGA you must choose from among the following output resolutions: 640 x 480, 848 x 480, 1204 x 720, 1280 x 720, 1280 x 768, 1280 x 1024, 1360 x 768, and 1920 x 1080.  Much like a PC you would want to select a lower resolution (640X480).  That will make your fonts larger.


Screen Format: The default setting is Normal (a standard 4:3 aspect ratio); select Widescreen to change the output aspect ratio to 16:9 if you have a widescreen TV or monitor.  You should select normal and not widescreen for a standard tv.

Hope this helps,

Bob
