When used as a comp monitor it's blurry

Try tuneing the tv in again! If doesn't solve the problem download manual

Could be many items but most likely the main video board needs updating or replacing. Google your model number and see if there is a software update that you need on your set.

I have bought brand new Hisense 40 3d fhd led tv but no power.How can I switch it on?

Note this system uses VGA quality images so will not be as sharp has HD cameras. Also, due to the number of cameras, you frame rate may suffer. If you are not using a flat panel monitor, try that to see if the quality is better.

if you hooked up a computer then you are watching a local tv station the video will be affected. their will be an interference on the signal. you must disconnect the cable going to the computer first.

Do you have a hdtv and a hdmi on your computer? If so that's the way to go, otherwise if the comp. doesn't support hdmi but you do have a newer tv, you could possibly take your vga cable from your monitor and plug into your tv. If that is not possible, then there are still options. There are different types of adapters you can get and use to mate the two together.

Dear Mmcdonald 23,
you require HD graphics card for better clarity and a corresponding resolution to be selected is also mandatory.the picture or movie that you watching also depends on the video quality please use Blue Ray or Dvd.for better quality
thanks

Make sure the speaker wire to the computer is to the lime green plug on the computer and power to speakers and make sure volume control on the computer is not muted

try differ input.

could you give more info?? how are you getting the signal out of the computer? have you tried other computers on the same monitor. could be the video out of the comp. do you have another source for the monitor you can use??
