Default PC To HDTV Concerns

Please help, I'd like to make sure I have the right idea and that I'm getting the right stuff to do the job; because soon I'll be getting a $2000.00 HDTV and PC. Basically I've been searching to get the highest quality in display for the PC to HDTV connectivity. So far my idea is to use the HDMI to DVI converter cable, with this I need to make sure my PC has a DVI port and that the HDTV has an HDMI port.

Is this method the best way for the best quality? Will this even work? And when I do this will the display be in high definition? I'm not sure, lol. But I've read HDMI is better then component so that must mean it's HDTV, right? I'm well aware of "overscan" too so I'm prepared to use a program called "Power Strip" to use the appropriate resoultions for the TV's 1080 or 720 display. I was also concerned if certain companies might restrict or prove troublesome for PC connections, is there a certain brand I should avoid?

I also wanted to know if the PC's video card has to have some kind of requirement in any way. Please help! Am I prepared?

PS: Obviously 1080p is better then 1080i but which is perfered for PC to HDTV?

If you want, you can try to get a video card that has an HDMI output already on it. Also, I've seen some motherboards that have HDMI video output. That would save you a step. Also, modern day video card drivers support resolutions for HDTV so you may not even need the program "Power Strip". If you choose to go the DVI to HDMI connection, then yes it will work for you.

And, yes, you will be sending the tv 'hd' from the pc. I dont know about the on-motherboard hdmi, normally on-board video processing is pretty weak. You will be driveing the hdtv at its native resolutions, no easy task. It will probably work fine for basic stuff...but things like 3D games and high performance screen savers will probably not work well with on-board video.

HDMI cards are just now starting to hit the market. If you want to go with a hdmi out card it will seriously limit the graphics card you can go with, and might cost you more (but then, I dont know, I havent priced them) Just remember, a dvi out card is just as good as a hdmi card as your graphics card will not provide sound anyway. A dvi to hdmi from a pc to hdtv will give you the best possible connection, I recommend nvidia (but maybe im biased because I have been so happy with my 6600gt), but ATI also makes some good graphics cards...BOTH create drivers for their cards that will make the pc-hdtv connection plug and play. Nvidia has been providing better hdtv support than ati, but nowadays both do a good job. Forget powerstrip, as long as you go with either card manufacture and your tv has dvi or hdmi, you wont need it (and be gratefull for that, its a pain to use)

A progressive scan signal is always best to an hdtv, so 1080p will be best to an hdtv. But, I dont know if most of the cards out there will do well with that kind of resolution, and displays that accept 1080p are still limited also. At this time, I would recommend a 720p display

Thanks! I've read that computers don't have HDMI, so this "on-motherboard hdmi" or a video card with an HDMI output is definitely a no-go, right? And so for to get the DVI to HDMI cable to work the PC will need to have a DVI port and the HDTV a HDMI port, correct? Also if I buy a 1080p HDTV, does that mean it will also have 1080i? Needless to say 720p. And lastly since 1080p display seems hard to get, would it be just as hard get a 1080i display?

Your best bet is to get a video card with a DVI port and a TV with a HDMI port. Then use a DVI to HDMI convert cable.

You are confusing the type display with the interconnect format. 1080i TVs would be CRT based and you don't want one of those if you are going to hook it to a computer. You definately want a fixed pixel 1920x1080p display. Also since you are hooking it to a computer you want one that will allow a 1080p/60 input. Some 1920x1080p displays will only accept a 1080i/30 input and you don't want one of those.

Also while you are at it, you want to make sure the deinterlacer in the TV operates properly. Check this out for more info: Are You Getting All the HDTV Resolution You Expected? Be sure to also read the referenced links in that article also.

Thanks alot! I forgot to ask a critical question. What type of TV do you think has the best quality for the PC to HDTV or just best overall. What I mean by that is plasma? LCD? LCoS? etc. I hear plasma has better quality but risk of burn-in would be much higher for me because of the PC display on it (wallpaper being viewed for a long period of time). Note I'll only be getting a TV in the range of 29'' to 36''.

In the size you have mentioned the LCD direct view is going to be your best bet. I'd check out the Westinghouse.

Thanks. Can I ask you a final, final, last thing?

Well I didn't really understand the answer to one of my questions which was "if I buy a 1080p HDTV, does that mean it will also have 1080i? Needless to say 720p."
Here again you are confusing the way the picture is formed with the way the signal is transmitted. On a fixed pixel display like a LCD the picture is formed in a progressive manner. A CRT would form the picture in an interlaced manner. Therefore the CRTs would be 1080i displays and a LCD would be a 1080p display assuming the display has a resolution of 1920x1080.

The second issue is how the signal is delivered to the TV. Broadcast HDTV is either 1280x720progressive or 1920x1080interlaced. Only a computer, Blu-Ray or game box is capable of delivering a 1080p signal to a TV as of this writing. Therefore to watch HDTV a display only needs to be able to accept a 1080i signal and a 720p signal no matter how the picture is displayed.

If you think about it, both the computer output and the display input should have the 1080p/60 capability.

It is not hard for all HDTVs. Mostly what you have read that is hard would deal with CRT based HDTVs. LCDs that are designed to be connected to a PC is as easy as hooking up a monitor. Where people get sideways on this issue is thinking all inputs on the TV are the same. Inputs meant for video devices such as external tuners, satellite receivers, DVD players will have overscan built into the TV input and those inputs must conform to the HDTV formats which are not necessarily computer video formats.

If the display has a PC input, usually VGA, then the hookup is as easy as hooking up a computer monitor. Otherwise hooking a computer to the cmponent inputs, DVI or HDMI inputs will require the computer to conform to the format the display requires.

If you want to hook up a HDTV to a computer, I would recommend you get a HDTV with a PC port and use that.

Default questions about connecting pc - hd tv

Rbinck >> i have a question for you...

Toshiba 50" DLP (50HM66)

Im looking to hookup my PC thru this DVI - COMPONENT adapter from ATI.. http://shopati.ca/product.asp?sku=2537967
I currently have a ATI Radeon 800XL which has DVI output..
i want to hookup my toshiba dlp hd 50 inch.. will this adapter work with this type of card, or do i have to have at least ATI 9500-9800 series card..... This device is sick, so i was just wondering if anyone could help me out .. In the instruction manual it says DO NOT attempt to hookup from PC to TV via HDMI.... so i need other ways to do it in order to get 720, or 1080 i ...

But then i was thinking just to get a DVI - HDMI adapter to connect the pc to back of the tv... however i was reading the instruction manual for the TV and it says DO NOT connect a PC via HDMI to tv as the HDMI port is not deisnged for pc audio... if i was using a DVI adapter to HDMI and then plugging the HDMI cable into the tv... its not technically directly connected via HDMI.... so would this damage the tv u think?



Thanks

But if you use a DVI cable with a HDMI adapter on the TV end (like I did), you are only sending video only. That should work fine and the best IMO. Those ATI component adapters are a bit hit or miss on the older ATI cards IMO.. I would give the DVI a try.

Good question. I need to know the answer also. I am considering the purchase of either a Sony KDL46xbr3 or a Samsung LN-S4695D or LN-S4696D LCD HDTV, all of which have PC inputs as well as HDMI inputs, and all three user manuals specifically say "You cannot connect this TV to a PC via HDMI/DVI" or "The HDMI/DVI jacks DO NOT support a PC connection". I am wondering if this has to do with HDCP (copyright protection) in the HDMI input circuitry? It doesn't make any sense to me to have to convert my PC's HDTV tuner card's DIGITAL signal to ANALOG, transport this ANALOG signal via the VGA cord to the HDTV's ANALOG PC input , then convert it back to DIGITAL after going through the HDTV's ANALOG PC input to be visualized as a DIGITAL signal. That would be DIGITAL>ANALOG>DIGITAL and I would rather keep this signal DIGITAL all the way. Or am I missing something? Please straighten me out. If I connect the PC via the graphics card's DVI output to the HDTV's HDMI input anyway, in defiance of the owners manual, would I risk damaging the HDTV or would I just run into hassels with the copyright protection? Thanks.

Hmmm, all these TV's saying you can't use the HDMI/DVI to connect a PC. If you have a PC/VGA connection, that would work just fine IMO. I know VGA and component are digital/analog/digital, but it is fine. I used to have my PC hooked up via HDMI, but changed to PC input to save my HDMI for another device. Works great IMO. Allot of Video cards now support HDCP and there are even a couple HDMI video cards on the market now. Perhaps someone that knows can say why these sets don't support/recommend HDMI input. Again, if you are using DVI with a HDMI adapter, you are only using video and no audio. Perhaps that are not wanting these new HDMI video card to connect to these displays..

Your manuals say this because, with a computer, it is very possible to send your tv the wrong timings and do damage to the tv. Luckily, most newer graphics cards have hdtv support via their drivers, so its not as much of a concern as it used to be. My original setup was a Voodoo3 to a Mits 55313 via a vga to rgbhv break-out cable using the program power strip to establish the timings and resolutions. THAT type of setup, if you dont know what you are doing, could have easily damaged my Mits.

If you have an available dvi or hdmi input and a video card with dvi or hdmi out I cant imagine you going with any other type connection. You wont get the text clarity with a analog connection to a digital display that you will with a digital connection to a digital display. Video via component is fine, but digital is prefered for text. Some vga, ala "computer", inputs on hdtvs limit your resolution choices as well, especially on some of the first hdtvs to offer the computer input

It won't damage it I don't think, but the audio will not come through is what they are saying. You should be able to connect the RCA audio from the PC though. There could be an overscan issue through the HDMI port as well.
