It seems to me that you are watchin an analog signal on a digital HD TV, the analog signal is has a standard resolution of 720x576 for NTSC (American Signal) and 720x480 for PAL (European Signal).

It could be worth to go contact your cable company, they can hook you up with a digital receiver which gives a better signal and might even have a HD Signal (this means it has a HD-Ready 1280x720 of Full HD 1920x1080 resolution).

If you really want to use your LCD TV on his max this is really worth considering

Hello rqromero2,

I found this on HP's website. I hope it helps

Picture quality problems (such as lines, fuzzy image, or wrong colors)Check the cables and connections:
  1. Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors.
  2. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
    Press the CH button to display a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal.
    For example: if the image quality issues occur while viewing TV, switch the source to a DVD player to see if the image quality problems go away.
    If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and .
    If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Open OSD to adjust the picture:
    Press the Menu button to open the OSD. Select the Picture menu and adjust the image as needed. 
    If you cannot adjust the TV to fix the problem, reset the settings from the OSD to see if the problem goes away.
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV. If the image quality problems still exists across all types of signal sources, the TV should be serviced.

If this dosent solve your problem, letus know and we will find another solution,

I have a problem with the picture on my Infocus IN1501. It has small squares on it and I see every pixel. How do I remove this?


Generally the screen is full of pixels, and thats a good thing.
It's a problem when you see the pixels that should be off, and don't see them when they should be visible.

So I presume that your pixel problem may be the first type where they appear when they should be hidden.

Now it would be good to know if the bad pixels are all one colour, or if you have chromatic pixelation problems.

Monochrome pixel problems are better than chromatic pixel problems. But alas all pixel problems come back to the DMD or the colour wheel.

Either way your machine is basically compost material for the garbage shredder, unless you want to pay big money to replace the faulty bits.

Ask the local serviceman or servicewoman to give you a quote to look inside the unit and see where the pixels have gone astray.

Flat panel TV shows a bright pinpoint of light in dark scenes


maybe or maybe not. It is a pixel that is stuck 'on' all the time. Not a warranty claim item as a few bad pixels are allowed.....

It does not spread, but that is not to say that another pixel somewhere else on the screen will not go bad.

The light engine bulb might be bad or going bad. Check it first. Then check its power source. These are you two most likely problems. I would suggest you having a TV technician perform this task.

I hope this helps,
