My lg tv/monitor dm2352 has tiny black dots like the distance between the pixels is visible when the image is bright. Should I RTM?

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Hello. If it resembles a tiny bright green dot, this is most probably a dead pixel. In the troubleshooting guide in the user manual, the manufacturer states that some pixel loss is normal--either they will be gone or permanently "on". If the unit is new(i.e. still under some warranty) talk with the supplier about options--they *may* decide to replace it if the dot is in a particularly annoying location. Be aware though, they won't be under obligation to do so. I own a LCD projector with a few visible pixels--as devices such as these(lcd tv's, projectors, plasma, etc.) age, this type of phenomenon is going to occur. Normally--and this certainly isn't always true, there is a tolerance of 3-9 pixels. Check with the supplier and/or manufacturer for individual specs. Especially if the unit is under warranty!--Hope I successfully assisted you.---Rick

If these are single pixels on the LCD screen, they are normal. From pg. 8 of the user's guide:

"The LCD monitor is manufactured using extremely high-precision technology so over 99.99% of the pixels are operational for effective use. However, there may be some tiny black points and/or bright points (white, red, blue or green in color) that constantly appear on the LCD monitor. These points are normal in the manufacturing process and do not affect the images in any way. "

This may also be helpful.

"images may trail across the LCD monitor in a cold location. This is not a malfunction. When turning on the camera in a cold location, the LCD monitor may become temporarily dark. "

Contrast ratio is the ratio between black and white. So low contrast ratio (5000:1) means you can;t see the screen so well in a bright room (where there's a lot of sunlight) A higher contrast ratio (20000:1) means the screen is brighter so easier to see in bright rooms.

Pixel pitch refers to the distance between pixels. The lower the pixel pitch, the sharper the image

Pixel Mapping is a feature of the camera to check and adjust the CCD and image processing functions. Locate Pixel Mapping in the camera's Menu and select OK to activate it. Once Pixel Mapping is completed the Menu displays. The bright dot should no longer appear in your downloaded images.
