Default is this a good time to buy pc to hdtv???

i'd like to hook up my pc to my hdtv. not to play media, but to use the hdtv as a monitor for my computer needs.

i tried a straight hook-up to the dvi connector, and the image on the hdtv was oversized and could do nothing about it.

after some googling, i came across these two products.... http://www.ati.com/products/hdtvwonder/index.html
http://grandtec.com/hivision2.htm

the ati card intrigued me for its recording functions, and the grandtec appealed to me for its ease of use(ie,,i could buy it, hook it up, and if it didn't work, i could return it. this is not so easy with the ati card.)

but amongst other issues, two of my friends posited this argument....that the technology is still new(maybe even first generation), and that i should wait until the kinks(if any) are ironed out, and also wait until the price drops.

well, i don't want to wait for a price drop, but i do have concerns about quality, and would like to avoid any hassles if either product doesn't work to my expectations.

what do you all think is the best course of action?
background....i have a sony rear, lcd projection kf60we610,,,and a nvidia 5600ultra vcard on my computer(wME). when i tried hooking up my pc/hdtv i was UNABLE to resize the desktop image, as it showed in zoom mode. i emailed sony tech support, and they replied with this statement, ""We apologize for the difficulties you are experiencing. The Wide
Modes of the television are to affect a standard 4:3 format picture.
When any high scan input is received by the television above 480P the
television will show the native format of the video signal. This
disables the Wide Mode functions of the television. The image that is
being seen is not from the television's "Zoom" Wide Mode."

would either product solve this issue as stated by sony..

thanks very much all, and thanks for reading this whole thing

i just now read the two posts above and they are quite informative.

but my original question still stands,,,ie, 1...the feasability of going through all that, 2...and what if the image is not what i expected(in which case, all is for naught)

btw,,,can i get a 1080 image off my computer if all goes well?

I don't know about the nvidia card. nvidia is not considered HTPC friendly, so most of the HTPC is centered about the ATI cards. Just what nvidia gamers want to hear, right?


I use an ATI 7500 PCI card and with the aid of the powerstrip software, it is able to output 1920x1080i. It also will output 1280x720p, so depending on the TV capabilities, it will cover HDTV.

The overscan issue is a factor of the TV not the equipment connected to the TV. The TV has the video height and width set to push the edges of the image off of the viewable area of the screen. It may be that you can get into the service menus and reset these parameters, but you may end up seeing video noise when viewing standard TV video. Some TVs have an input specifically for computer input, normally VGA, that will not have the overscan. I have a multimedia TV that is so equipped.

As far as using the HDTV for a computer monitor, most HDTVs will make a terrible computer monitor. Most HDTVs are fixed in a very narrow refresh rate at 59-61 Hz, so they are basically 60 Hz devices. This will normally cause flicker to be noticable on text type displays. Take the HDTV resolution of 1280x720 @ 60Hz, the closest standard computer resolution would be normally 1024x768 @ 75 Hz or 85Hz. Most HDTVs can not handle this high refresh.

thanks.

do you see anything on the horizon that will address this better?

and btw,,,,when i hooked up my pc/hdtv through the dvi, even though i didn't get the full screen, neither did i notice any text flicker. it didn't look like 720 either,,,,more like 480.

Yes it probably was 720x480p or 640x480p. As you go up in resolution the flicker becomes more noticable. Since you have the TV already I suppose what would be available on the PC end is the question. So far I've not come up with answers that would allow your TV to be a good monitor.

my vcard has a 60hz option on all the resolution settings, including 768 and 1024.

i always thought the available resolution/refresh settings were determined by whether those settings were native to the monitor....and that the vcard just gave me the options based on what the monior says it can handle. this is NOT true??

Milti-

You'll likely not see flicker at 60HZ because of the persistence of an LCD monitor. It simply doesn't switch on & off as fast as a CRT; that's why most computer LCDs can easily get away with 60HZ native refresh rates.

Another PCI tuner card I found (but haven't yet checked out) was found here:

I have no idea if it's all that, but I hope to find out soon. It sounds like just what I'm looking for...
