: All About HDTVs as a PC or Laptop Monitor

Ok...i've got a second widescreen in the house.........an LG R45W46 rear proj. I just came across another pc......which only has vga and svid outs. I would prefer to hook this MCE pc up to the LG with the best possible connection. With the LG only accepting one DVI w/HDCP, and two Components.........what is my best route to go?

I just bought a Samsung HLT6187 and was wondering if I can just plug my pc into the VGA on the back and set the output resolution to the native 1920x1080?
Will this work or does it require hdmi/component?
Card is a nvidia 8800gts.

awesome, I just finished the 100 page user manual and the new generation samsung's can do 1920x1080 via dsub (regular vga plug) or via dvi->hdmi and they fully support it !! You can even tell the tv that its being used as a pc monitor and it adjusts its cropping accordingly so you don't lose your taskbar.
Very happy with Samsung right now :D

so absolutely no one has used a plasma with a pc ??? Is it just me! ?

MAU108: As soon as my costco special arrives i plan to hook my pc to the 42" plasma... Ill setup power management and screen saver to kick in soon as well as let my taskbar disapear when not needed to avoid burn in, i really only want the ability to watch reruns or torents off the net, so aplications wont get run, depending on how it looks the odd game if the wife is in bed :)
IS there risk of quality loss running a long dvi to hdmi cable form my computer room to my plasma? Say 20-30 ft? Im contiplating movig my pc to the room behind the wall of where i plan to mount my plasma down the road. im hoping if i do that my wireless mouse and keyboard will work when i grab them and walk into the tv room, if ther is range issues i may try to mount the usb receiver behind in the wall some how..

You won't have an issue if you use the belkin mediapilot (which is what I use and factorydirect had a sale on it, 40 bucks, best price ive seen!)
It actually has mouse controls on it (bit tedious to use but you get used to it) and best of all, no direct line of site is required, it works on 2.4ghz (so if you have a microwave or cordless phone that is 2.4ghz or even a wireless network you may receive interference in which case it wont work well)
Next thing, the 30ft dvi cable, although its gonna be expensive, i don't think you will loose any quality.
Let me know how it goes, I'm going to try the original nvidia driver tommorow (using the ngo hq drivers which are tweaked nvidias)

May have already been discussed, but given the choice between a 25' vga -> vga cable for my hdtv (because it has the port for it on the back) or a dvi -> hdmi cable, what would be the best concerning price and quality?

I have a sharp 1080p LC32D62U TV and I have my PC with Ati Radeon X1950 pro connected to the HDTV via monster DVI to HDMI cable (supports 1080p)...However, the problem is that the maximum resolution I am able to get is only 1360x768 (768p) for PC input in my Sharp TV...Is there any way I can make it display 1920x1080 (1080p)..I tried forcing the resolution via Ati control center but it is not being displayed properly...any help would be appreciated. Thanks!
2007-05-31, 03:18 PM
Update: 1920X1080 @ 30Hz (1080i) seems to display properly...However 1920x1080 @ 60 HZ (1080p) is still not being displayed...Display appears scrambled...I use a Monster Ultra 800 DVI to HDMI cable and it says it supports 720p and 1080i on the retail box...So is the problem with 1080p not being displayed a problem with the connecting cable or does the Sharp LC32D62U TV does not support 1080p PC input?
It's unlikely the issue is with the cable. Even a $5 DVI/HDMI cable will do the trick. You may wish to check out the following thread.

it says it supports 720p and 1080i on the retail box
If that's what it says, it might be correct. IIRC, a single link cable does not support 1080p. A dual link cable might be required. These are available at Monoprice and other vendors for a lot less money than Mon$ter cables.

Thanks for the reply both...
I_Want_My_HDTV@ I checked the difference between single-link and dual-link one's and here is what I came across...The below link says that a single-link cable should be more than sufficient for 1080p.
1080p 60Hz HDTV video signal
Considering that a single-link HDMI can transfer up to 165 million pixels per second, it is clear that HDMI has more than enough bandwidth on a single link to accommodate even the highest HDTV format available today for consumer electronic products. In the case of a dual-link mode, an HDMI cable connection can handle a bandwidth of up to 330Mhz.

I guess I was wrong there. According to the article, standard HDMi cables in use are equivalent to single link DVI-D and should handle 1080p. Maybe the ATI drivers don't support HDTV 1080p format. Just setting the resolution to 1080p does not guarantee HDTV compatibility. There are special 720p and 1080i timings in the drivers that are HDTV compatible. I don't recall seeing 1080p timings but it's been awhile since I looked. Unless, specific HDTV 1080p timings are supplied, you may need to do some tweaking.

ok so some images to go with my problem, pics speak a thousand words...I can't believe no one has run into this problem :S
I'm planning to use PCI HDTV card for OTA reception. The problem that I have is that my TV is in the family room on first floor and my computer is on the second floor. (I don't have a place for it near the TV).
What's the best way to send the signal from PC to TV? Is there any kind of HDTV RF modulator so I can use coaxial cable in my house and then use TV's tuner to demodulate it? I think it will be to expensive to run component or DVI cable between the floors.

I am assuming that your TV already has an ATSC/QAM tuner and you are wanting to use the PC to record programs since the TV would need that to decode the signal in HD. To the best of my knowledge, no one makes a consumer level ATSC or QAM encoder. The only feasible way to do this would be to connect via Firewire, USB or Ethernet over which the MPEG stream that was recorded could be sent (real time HD MPEG encoders are still very expensive and the extra decompression/compression would degrade the picture), but even then, I don't think anyone makes such a beast.
I think your best solution would be to use either VGA or component video cables. If you are worried about cost, you can make your own component video cables.
Another other option would be to stream HD video to an Xbox 360 or PS3. I have never done this, but I have heard that it is possible.

I just recently bought an NVIDIA GeForce 8800 GTS GPU and was looking to buy a new display to go along with it. I was looking at both HDTVs and LCD Monitors. I really have no idea what the advantages of each are and was wondering if I could get some advice. I will primarily be playing PC games on this display, as well as Xbox 360 games in the future. My budget is under 500CAD and I would like to buy a widescreen display. Any help would be appreciated.

My problem is that i have recently connected my PC to my new Samsung HDTV using a blue cable which is called a DVI cable i believe. The video works perfectly however the sound is not coming from my PC, and i have to connect my speakers to the PC for sound (which is a bit awkward and annoying).
I have tried researching the problem myself, i came to the conclusion that i need to connect my soundcard (in the pc) to the HDTV, but im still clueless on how to do that. What cable do i use, and where do i plug it in.
Thanks in advance.

In this scenario your best bet is a headphone to RCA cable. You'd plug the headphone end into the green jack on the laptop, then the red/white RCA into the corresponding ports on the TV. There should be RCA jacks that correspond to the DVI input on your TV. Do that and you're rockin.
2007-07-20, 06:20 PM
thanks for the help Chaseme, i googled image what a headphone to rca cable looks like. And if this is a cable with 3 connectors in blue white and black than i will be rocking, because coincidentally the HDTV came with such a cable as extra.
I will try it out first thing in the morning
