I think your graphics will do fine, and running the standard drivers will have a 720p format in the list...

What is the resolution of your notebook's LCD screen?

Default PC to 4:3 HDTV

HELP ME! (Picture the Exorcist)

10 yrs ago I bought a Gateway Destination system, which basically allowed me to watch TV and operate my PC from my couch. It came with a 31" computer monitor (not TV), with VGA input. We had 800 x 600 resolution, and we have LOVED IT!

The monitor has seen better days now, and my wife wants to be able to watch TV like a normal human every now and then. SO, the idea was to buy a HDTV, which we did. Sony 32" 4:3 HDTV Flat Tube, and a Media Center PC, which we did (Sony VGC RB38G)

SO, Not so fast, it seems
I've tried everything (bought new ATI x700 pro card, downloaded latest Catalyst drivers, bought PC to TV VGA converter from Grandtec, bought KeyDigital KD-VTCA3 VGA to component converter, and dvi (pc) to hdmi(TV) cable, and I can get 95% there, but picture still a little blurry.

I have downloaded powerstrip, and don't know enough about it to figure it completely out. I tried a little, and lost the display, so, being from North Carolina, I simply switched the ati card back out. That fixed it.

The best quality is the dv to hdmi cable, but it comes across at 640 x 480, which I do understand is 480p, and a resolution that the TV is looking for. But, the computer and many applications don't like my display being that small.

I can get a 16:9 resolution with an ATI DVI to HDTV adapter, but it is too small to read email from across the room.

How can I get 800 x 600?

PLEASE HELP ME!! I'm desperate. My wife now thinks I'm doing something wierd staying up til 2 am every night with the computer...

__________--
Computer Outputs ati x300 (or x700): VGA, RGB, and DVI

TV Inputs : Composite, SVideo, Component, and HDMI...

I have got a Hitachi 32LD7200 which I have just connected my PC to using a DVI-D single link cable from an Nvidia FX5200 graphics card and I am having trouble getting it to display 1360x768 in full screen, at the moment it will only pan across. I have tried using the latest drivers 77.72 and the latest version of Powerstrip, they both have this resolution in the list to choose but it still pans across the screen.

Please can somebody give me some advice on how to resolve the problem.

Thanks

Martin.

There's no reason to think your TV will support an 800 x 600 res, it's not one of the standard ATSC formats. HDTV formats are much better for PC desktop, but they are widescreen as are all HD formats... so they'll letterbox on your 4:3. You could try 848 x 480 - which is EDTV mode, widescreen.

In one of the first posts, rbinck had shown how to enter the specific timing settings based on the info that Monoinfo gave. I tried to follow that lead and type them into my video card's settings. My card just said, that i could not change the settings, and nothing happened. Now im wondering if i did something wrong, or if i have to follow a different procedure in order to get it to work with an Nvidia card.

Select the standard 1280 x 720 res from your graphics driver, 24 or 32 bit color, and LOCK the refresh at 60 Hz. 'Optimal' refresh will NOT work, it MUST be 60 Hz ONLY!

I definatly tried that already. The picture is distorted. Runs off the edges. I then used the Overscan utility to correct the mess, but now the picture looks stretched(squished vertically). My tv is 4:3, is there any way to get it to display in widescreen withought running off the edges, meaning having black bars at the top and bottom, like watching a widescreen movie?

Default resolution change at reboot

I have a Sony KDF-60XS955 60" LCD projection TV that I use as a computer monitor with a Chaintech MX4000D graphics card. I'm using the DVI output with a DVI to HDMI cable to the digital input on the TV. I have the resolution set to 1280X720 and have a beautiful presentation except for a slight overscan. My problem is that everytime I turn on my computer (XP Pro) windows resets my resolution to 800X600. I have even tried using PowerStrip 3.47 to no avail. Does anybody have any suggestions? Thanks

First guess is that something about the monitor info the LCD is sending (or not sending) to the PC is throwing it off. I would try this trick:

Default Someone please help! Not an idiot, just ignorant

Well, I bought a HDTV *just* to extend my pc onto and I found out it isnt just PnP. I have been trying to get my New Samsung TX-P3064W to work with my Geforce FX5200 (latest drivers 77.77), and followed some of the tips i found in this thread, came close (can get a descent 640x480) but i am ignorant to this HD thing. I am learning fast though, thanks to this great forum! I was hoping that one of you veterans could look at my moninfo, and hopefully tell me what I might be overlooking.

In one of the first posts, rbinck had shown how to enter the specific timing settings based on the info that Monoinfo gave. I tried to follow that lead and type them into my video card's settings. I've tried a few walkthroughs with limited success. I was making slow progress but got stuck after getting the 640x480 up. Incredilble frustration. I know that as with most other geeky things i do there isnt really anyone to call for help, so this forum is a blessing. Anyone who can assist me I will pray to for eternity!

The best way to use that data is with a program called PowerStrip, you can just copy and paste the lines into PowerStrip and generate a custom resolution.

Yes get powerstrip as suggested. Also this repost from an earlier nvidia user may be helpful. He was having trouble with overscan, but the drivers referenced may be just what you need.
Quote:
Nvidia's new Forceware drivers cured it all. These drivers add Consumer electronic display support for DVI-based digital displays, such as widescreen plasma screens (CEA/EIA-861B) according to Nvidia's website. There's a nifty little program called NVKeystone I think in the download that allows you to adjust the screen size from corner to corner. I have my entire computer screen visible now. http://www.nvidia.com/object/winxp_2k_61.77.html
Good Luck

That NV Keystone is actually there in all newer versions of the NVIDIA drivers. I have never used it, but I found it easily enough, just do a search for "keystone.exe". However you don't want to use it if possible, it is a special tech made to correct for like projector display distortion, and as such requires a bunch of system power to do it.

NVIDIA's newest drivers have all sorts of overscan/underscan, etc. options that would probably work better.

Hmmm, wish i was at home to try that now. Just might work :-) I dont think i have overscan issues as the resolution looks to be just right. I can manually tweak the refresh rate and get an almost perfect picture (little fuzz around letters and icon) but when i drag a window over there it just flips out like a bad acid trip. I was trying to add custom resolutions in power strip but they wouldnt be available in the slider. I will try the pasting thing when i get home. I have a good feeling about it :-) I was trying to paste the whole line in but now i see that was just stupid. Anyhow out of curiosity what does the information past the resolution on the modeline refer to?

I will post and let you guys know if the pasting worked, almost wanna ditch class ;-)

Thanks!
