Laptop/tv hookup sometimes tv goes black watching videos

I hooked up my laptop to my lcd tv using an vga to hdmi adapter. For the most part it works great, the problem i'm having is when I try to watch online videos on my tv every so often the screen blacks out for 3-5 seconds and then comes back on. Does this mean possibly my adapter isnt working properly or could it be a bad vga cable or possibly something else i havent thought of yet?(my lcd doesnt have a vga port, just an hdmi, which is the reason I got the adapter)

It could be not enough video memory and it take a second to process data. with streaming video it uses UDP protocol. UDP uses a simple transmission model without implicit hand-shaking dialogues for guaranteeing reliability, ordering, or data integrity. Thus, UDP provides an unreliable service and datagrams may arrive out of order, appear duplicated, or go missing without notice. UDP assumes that error checking and correction is either not necessary or performed in the application, avoiding the overhead of such processing at the network interface level. Time-sensitive applications often use UDP because dropping packets is preferable to using delayed packets. from WIKI http://en.wikipedia.org/wiki/User_Datagram_Protocol
this is probably why sometimes you just miss packets of data. and it displays black or nothing

    does there seeme to be any pattern to the outage an in like every 30 seconds ... not if you are streaming video you are just going to miss packets and that is just haow the protocol works now if it were TCP you wouldn't have that problem but you need to down load and buffer data befor you could watch it. it also hase something to do with the transfer of that data over a hdmi cable it is sending alot of data and when it misses a packet it take a second to catch up.

What product would I require to hook up my Compaq laptop to my old TV Sony Trinitron to be able to watch films??


It all depend what output is available on your laptop. From what i see on internet your TV has front input for sound and composite video (yellow plug).
If you have VGA connector on laptop than you can purchase VGA to Composite video adapter, sound will come from ear phone output on your laptop.
If your laptop has only HDMI output, than you can buy HDMI to Composit (S-Video) adapter. Those have also audio out since HDMI carry both sound and video.
You can check internet for where to purchase those in your area.

Unless the tv has a VGA input, or the laptop has a HDMI output, I am afraid you are going through too many conversions to make this work.

I have a Dell computer that runs Windows Vista and I want to hook it up to use my TV as a monitor to watch a webcast. Please advise.


The first step is to inspect both your laptop and TV and identify the connections, easily located on the back of either component. There are five basic types of jacks, or ports involved:
*Composite/phono plug (RCA)
*S-Video
*Video graphics array (VGA)
*Digital video interface (DVI)
*High-definition multimedia interface (HDMI)
*An RCA connector, sometimes called a phono connector, is used for analog audio and video components. Three round, colored sockets are standard — left audio is white, right audio is red, and composite video is yellow. These are standard jacks on older TV’s and laptops. A three-prong cable, readily available at any computer or electronics, is the easiest way to make an RCA laptop to TV connection.
*S-Video, or Super-Video, a more advanced analog video connector, uses a four-prong round plug, like those used in TV cable installations. Separate audio cables are the same as for the RCA connector, left audio/white, and right audio/red. S-Video is commonly found on older TV sets and some laptops.
With S-Video on both TV and laptop, connecting a laptop to a TV is a simple matter of a single S-Video cable. If your laptop has a great sound system, you won’t need audio cables, but for better quality you’ll also want audio cables.
RCA to S-Video cable, a special laptop to TV cable, is available when you have RCA jacks on one device and an S-Video port on the other.
*A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable.
*A DVI port is rectangular with 24 pins arranged in three horizontal rows of eight pins for digital video; separate RCA analog audio cables fit into white and red plugs. DVI ports are found on Macintosh laptops; sometimes they are smaller than normal DVI ports and require an adapter, which usually comes with the laptop.
*The HDMI port, one-half the size of the DVI port, is also rectangular with 19 pins. It provides digital audio in addition to digital video, despite it’s smaller size, for a complete TV to laptop connection. These ports are found on new HDTVs, and sometimes there are two or more. TVs with HDMI ports are the only ones that do not require additional audio cables.
TV’s with a single digital port labeled HDMI/DVI require only one cable when the source is another HDMI component. But when source is a DVI laptop, you need a DVI-to-HDMI cable for the video and a separate pair of RCA analog stereo cables.
NOTE: Whenever ports do not match, you can by adaptors and/or cables to make any connection.

What do I need to hook it up to an hdtv...what type of cables..DVI-D to HDMI?


Your laptop will need a HDMI output or a DVI output for HD video. If your laptop only has a VGA out the your tv will need a VGA or DVI input. You could use a vga to dvi adapter if your tv does not have a vga connector. They do have a DVI to HDMI adapter but there are a couple of problems with that. One you will not get the sound and the TV will only obtain sound from HDMI cable when connected that way and Two the TV will have problems processing the signal from the computer due to the HDMI will only process the HD signals at certain formats and the computer video can send out many different signals. I tried and I could not get my tv to process the signal so I got a video card that has a HDMI out and my blu-ray player works great.

How do i connect my laptop to my lcd to watch films off the net


Depending on how old your laptop is, or what make it is, you may have few or several options. Some manufacturers have their own proprietary adapters/dongles for video out, but most at least give you VGA out, and others may have DVI, or the newest: an HDMI connector at the back.
If a proprietary dongle is provided, you're stuck with whatever it is they offer. It could be as poor as composite video (3 leads: yellow, white and red), S-Video (better), or best: component video for HD viewing. The first one offers you standard 640 x 480 definition, at 4:3 viewing ratio, while component offers you 1080i, using three leads to connect your
laptop to the LCD. Fortunately, most LCDs have component connectors. If the latter is available, this would be a great option, provided your LCD supports at least 720p, considered to be HD, though not the highest HD. The highest is 1080p.
Depending where you are in this wide scenario, the main thing is to get your LCD TV (I assume) hooked up the right way. The simplest way is to connect it using VGA, assuming your LCD has VGA as an input option. The next one would be to find an adapter to make the match. eg: DVI to HDMI, or vice versa; or VGA to DVI, etc. However the ideal one would be to have matching connectors at both the laptop and the LCD TV: HDMI to HDMI, or DVI to DVI, or component leads at both ends.
Good luck!

I have a 40in sonybravia KDL 40v4100, 1080p. No hdmi and audio w


HDMI is a video AND audio cable. It carries both at the same time. Typically with a laptop, you have to go into your audio settings and indicate HDMI audio enabled / set ON or whatever your software has. If you use a VGA connection, then you would use a separate audio hookup say from the earphone out on the laptop to the VGA's audio input port on the HDTV. Its all in the settings on the HDMI capable laptop.

Trying to hook compaq presario laptop to philips lcd digital tv


hey fox,
sounds to me like a connection problem. If the compaqs output is vga, you need to convert the input (tv side ) to hdmi, component, s-vidio... what ever you can find. Typically when you hook up your computer to a flat screen or such, its best to try to use the hdmi ports or the rpg. But if thats not available you need to take the outout from your laptop ( whatever type that might be and input it into your flat screen tv. If you input laptop into tv under ( eg..HDMI) then when you VIEW it you need to select the correct source on your flat screen. Such as hdmi or pcmi or rpg.I know that the do sell alot of cables that adapt from one type of connection to another. Typically only one cable is required from the laptop to the flat screen. If you think about it you are only using the flat screen as a monitor.
