: All About HDTVs as a PC or Laptop Monitor
2007-02-01, 10:13 AM
It's just curious to see Apple/Dell/Samsung selling 30" 'monitors' for $1500+, while you can get a Viewsonic/Westinghouse 37" LCD TV for less than $1K. What's the real difference?
Native resolution for one. For example the Dell 30" UltraSharpTM Widescreen Monitor has a maximum resolution of up to 2560 x 1600 pixels.

I have a Radeon x1300 pro and a 52HMX85, but I'm getting nothing more than a black screen when attempting to connect with dvi to hdmi. Resolution's forced to 720p.
However, other threads I found on this site suggest that this setup should work. Has anyone reading had any success with this?
2007-02-08, 10:19 AM
I don't think your Radeon x1300 pro supports HDCP (high-bandwidth digital-content protection). Most (if not all) TVs requrie that the HDMI sources use HDCP.
2007-02-08, 10:30 AM
The X1300 definitely doesn't support HDCP, but that should not be required to connect to the TV.
In all likelihood it is a handshake issue and/or the driver is not sending a timing that the TV recognizes.
The best option for debugging this, assuming you have a second PC, is to VNC into the one you are trying to connect to the TV and change the control panel settings for the video card until you get one that works.
I haven't used ATI in a while, but I believe there is a "treat display as HDTV" option or something like it.
2007-02-08, 11:28 AM
Yeah, I didn't think I needed HDCP to connect it to a TV...there are many people, at least from what I've read, that have successfully connected to tv with dvi to hdmi, with made-by-ati cards (none of which are hdcp compliant).
Anyway, I'm trying to set up the TV as an extended desktop, so I don't need another PC as I've got my primary monitor tht I can use to change the control panel settings. I've tried sooo many settings and I haven't been able to get anything, not even a flicker, on the TV. I thought it would be as simple as setting the resolution to 1280x720 @ 60Hz since that's the native resolution of the TV. No dice.

Dual monitor/extended desktop configurations have always been problematic.
Your best bet is clone mode if you are going to try dual monitor.

Hi... I have been down this path specifically... excpet with my JVC HD-70FH96
Started with AIW9700... same thing you are describing. could get 720p(60hz) working no problem with DVi to HDMI.
1920 x1080 at 30hz... no luck at all.... I searched high and low every web site I could find... no luck!
Found a great thread at AVS specifically for ATI and HD resolutions because some kind of bug.... search for user by the name of brandeborg. Great guy great thread... but after a few months of trying.. still no luck! So ended up trying a regular 9600 card... and it worked first time!
Then I got a x1300... and it work first time! 1920 X 1080 at 30hz. 1080i input to the TV on DVI to HDMI.
Of course latest drivers are always a good thing...
One thing that is important to note... does the ATI s/w at least detect your TV as the right model and as a DFP.
Good luck and I can truly empathize with your dilemma.
Let us know how you progress.

I've tried clone mode which also doesn't work, although clone mode wouldn't really work for me anyway since my monitor is not widescreen so I can't use a widescreen resolution.
Last night I tried what seemed like every possible resolution..still got no activity whatsoever on the DFP. I've the most recent Catalyst (7.1). The ATI control center detects the tv as a DFP, but the wrong model; detects it as TSB-HM84s (mine is an HMX85).
I tried using powerstrip but I didn't really get anywhere with it as I had no way of knowing what kind of tweak might solve the problem.

I've just ran a component wire from my 7600 GS card to my HDTV. It works fine as an "extended desktop" and I can choose the TV resolution with the Nvidia Control Panel.
However, I didn't find how to do precisely what I was looking for: display the same Windows desktop (not extended) on my TV, but at the TV's resolution (720p).
This is not clone mode since I want a different resolution for the PC and the HDTV.
I wanted to do this so I could browse my files while in the living room. Right now, the TV is only displaying my desktop background. There's mode that play fullscreen video on the TV while they play on the computer, but that's it.
Is there any trick I could use?

Cannot be done with NVidia cards.
2007-02-14, 06:12 PM
Is it possible with ATI?
I just bought my card :(
What people with software like MCE do with their nvidia card?
2007-02-14, 06:38 PM
There was a time when some Matrox cards allowed something like this.
Today they are not a player in the HTPC market.
You'd have to learn to live with this limitation.

I have the Asus 7600gs card and it is possible.
What drivers are you using? Make sure you are running the latest. (93.71 I think for Win 2000/XP/MCE)
There should be an option for "dual view" which will allow you to have two displays at different resolutions. Try running the multi-display set-up wizard.
I have trouble all the time with my set up, Dell 2005 widescreen monitor with Panasonic AX100 projector, the pj is not always on so when I reboot it often is not recognized and using the "Force HDTV recognition" does not work.
Make sure both displays are powered on when you boot your computer. I recommend that once you get the drives to recognize both displays as dual view and you have your resolutions set properly you can save as a profile. Plus do separate profiles for each display in single display mode.
2007-02-14, 11:42 PM
Well, I have installed the latest driver, but I'm not sure about the second part: is it possible for the TV to display the exact same thing as my PC Monitor (but at a different resolution)?
Right now it still used as an "extended desktop" with dualview (rather than a clone of my desktop).
diogen: are you saying that it impossible to do that with Nvidia AND ATI or just for nvidia?
EDIT: I've found a shareware called "TVTool" which is useful work around. I'll have to see if I can get it to work at the right resolution.
2007-02-15, 04:40 PM
are you saying that it impossible to do that with Nvidia AND ATI or just for nvidia?Yes. Both, ATI and NVidia can't do this to my knowledge.
Resolution, colorspace and refresh rate have to be the same when in clone mode.
If not in clone mode, you won't have your desktop icons on the secondary monitor.
I don't understand what dogbolter says.
I haven't tried the TVTool software.
2007-02-15, 10:55 PM
I think I misunderstood what you are trying to do here.
I run my projector as a secondary display at 1280x720 and my monitor as primary at 1680x1050. Desktop icons are on the primary and I can have applications such as Theatre Tek DVD player on the secondary. Both displays are not identical. Sorry for the confusion.
If you are not going to view both displays at the same time you can set each displays resolution as a profile under 'nView Desktop Manager' --> 'nView Profiles' and then toggle between the two using a hotkey.
I can't find the guide on how to do this but I remember reading this thread that explained how to do it using a remote and MCE, you can apply the same principle using just a keyboard stroke.

I have a Sharp LC32D40U that I'd like to use as display for my IBM T43P laptop. The laptop has a VGA and S-Video.
I have a VGA-to-Component cable. I hooked it up but it didn't display anything on the TV.
I called Sharp support. The answer I got was that LC32D40U doesn't have this support built-in, so they couldn't help me. The guy said that it's not impossible, but I am on my own.
Does anyone have had any success using LC32D40U as a computer display?

I need to run a video\audio cable between my HP7360n to my Toshiba
Since I am hoping this is a 1 time job (patching required:mad: ) I want to make sure I use the best possible one the 1st time.
According to the Manual these are my choices:
- Component (Y Pr Pb)
says component is Toshiba's brand called ColorStream
supports 480i, 480p, 720p, and best with 1080i
supports 480i, 480p, 720p, and best with 1080i
It states that HDMI port is not design to support input from PC
It states it can connect DVI with HDMI-toDVI adapter cable, but I will
be using the only available HDMI port for Bell EV HD Set Top Box.
Can I use a spliter?
- Analog RGB 15-Pin
supports 640x480, 800x600, 1024x 768, 1280x1024 all at 60Hz
My HP Video Card is a NVIDIA GeForce 6200SE with DVI, S-video, and VGA output ports. It is not the best card, so I am willing to upgrade.
Any thoughts on
- ATI Radeon X1950 Pro / 256MB GDDR3 / PCI Express / Dual DVI / HDTV / CrossFire Ready / HDCP / Video Card, $299.99
One thing I should mention is that I also use the HP PC as a desktop to a HP f2105 monitor with VGA, and DVI-D connectors.
Thanks for any help.

Component will be your best bet since you only have one HDMI and it is already in use.
Most new video cards have native component support, usually via a dongle connected to a video out port on the card which looks like S-video but actually has more pins. I'm a little surprised that the 6200 doesn't have this already.
The card you mention should work but depending on what you want to do on the TV it may be overkill. There are many less expensive options that will allow you to connect to both the TV and the PC monitor.

So I want to use my second DVI out on my computer and put that into my second HDMI input on my TV (Toshiba 42HL196 ) and run it at a high resolution. So I hooked it up and cool it works and looks sweet!
The problem is a couple of weeks later I decided I should read the manual. It says with a ! DO NOT CONNECT A PC TO YOUR TVs HDMI CONNECTION. :confused:
So does anyone know why?...am I going to screw up my TV? Will I get good results if I just use the VGA connection? (I havn't been able to test this as I don't have a VGA cable...oh ya and it needs to be 50ft)
Thanks for any help :)
