What cable do i need to watch netflix from my pc to my flatscreen?

Are you using a computer to play Netflix? In that case you need to connect your computer to your TV.

This can be done with multiple kind of signal cables (depending on what kind of input your TV has, and output your PC has).

The most common way with newer TVs and PCs is using a HDMI-cable. This is also the easiest way, as it usually connects automatically when you put the cable into your computer and TV.

This is a standard HDMI-cable:
This is what a HDMI-Input looks like.

its is telling you the truth (99.9999999% of the time)
believe it !

no PC stated
no TV model stated nor clear connections stated.
are you trying to get the PC (the tower means that)?
to run to video concurrent ports at the same time?

so do both fail,
VGA side
and DVI side,
you never said.

hard to help lacking
what TV
what Tower
what connections, and special adapter (HDMI)
the TV has DVI??
sorry, cant see what you have there. at all.

get it repaired, in shop.?
that is what most folks do when cars or appliances fail.
or learn to fix them your self. (takes lots of skills)
here are some tests (checks) but do know we cant see it or hear it.
watching a show, as in watching what, name it,
eg. my guess ,you were streaming .videos online, who's videos
netflix or youtube or what.

1. it oveheated. sure.
2. lost internet connections.
3. that TV has issues, try a different one , to prove this.
4. the PC is failing, (infected with a virus)

a more simple list
internet fails. (run internet speed test yet?)
TV fails.
PC fails.

its one of those or a bad cable.

You need a monitor video driver for the Samwin monitor part of the TV. google for the driver download with the SamWin model number?

Hook it up as u would hook up a regular monitor,Turn on the tv power.U the remote see a button said function press it selected PC in.Now u use as a computer monitor.

There should be a 3.5mm stereo phone jack on the monitor. You need a 3.5 male to 3.5 male cable to plug the monitor into the speaker out from your PC. Cable can be purchased at Radio Shack for under $10.

This TV uses a standard power cable that is also used in many other TVs, monitors, and computers. It is a CEE 7-7, which is often called a 'PC power cable' or 'standard 3 prong power cable'.

You should be able to find them almost everywhere, but your local Radio Shack, Bestbuy, or Walmart are all sure to have them.

it sounds like your graphics card is conflicting weith your flatscreen , i had a sony desktop do the same thing only on a TFT or LCD monitor , you may want to get a better graphics card , my bet is its probly an intergrated one .

You may need an adapter plug. They come with new monitors so ask around to see if anyone has one you can borrow.
