Hi

I've just bought a 32" Uniden LCD TV, with the main desire of plugging it to my computer. My graphics card has a DVI connection for the monitor. Not many of the LCDs had DVI, as they've all gone for HDMI. The salesman was vague on PC matters but said I can get a DVI to HDMI adapter, and that it would work through the HDMI input on the tv.
I got an HDMI cable and DVI/HDMI adapter, and thought it would be as simple as plugging it in. But I can't get an image.
My ATI card allows me to set up two monitors, but I'm not sure how, and if I have to get another graphics card to do it or not. I spent hours trying different settings and combinations.
But even just unplugging the monitor and pluggin in the LCD tv, I can't get a picture. I get the Windows start up screen fine, which is weird. Sometimes I get a very fuzzy desktop image, but if I use the mouse the PC locks up and I get a blue warning screen.
Also I don't want to damage the LCD tv by sending inapproriate signals to it.
I've spent hours searching google for answers, but so far, more mystery.

Any advice, anyone?

Most LCD HD TVs are "safe" at 1280x760, so try lower your screen resolution to 800x600 or 1024x768 or 1280x1024, or if you have WS resolution, then choose 1280x760.

As for dual monitor, it will depend on graphics card and driver, and set it up through the graphics card's control panel. Windows XP's screen properties has basic multimonitor support but that will depend on the graphics driver and card on which method to support.

Typically, a DVI and VGA output on graphics card can be set to display spontaneously, either mirroring or extended.

If you read the manual it will tell you the exact screen resolution and refresh settings that your TV will support. If you have your computer set to something else you won't get a picture.

There are also a large number LCD and Plasmas also won't accept PC input via HDMI but only via the PC input. If this is the case with your TV you'll need to get a DVI->VGA adapter to use the VGA input on the TV. Try reading the manual and see what it says about using your PC, I'm sure it will tell you exactly how to set it up.

I've just read the manual online and realised this TV had no VGA input which is pretty unusual. There is also no mention of PC support or whether you can use a PC via the HDMI input. I would suggest contacting Uniden and asking them if the unit will accept an HDMI input from a PC. If it doesn't your only real choice is to return the TV.

My Philips LCD which has HDMI, can take DVI input from PC with DVI-HDMI cable. Though, I don't use DVI cable and DVI-HDMI adapter like the Op did.

Also, DVI has 3 types, DVI-A which is Analog (VGA in DVI shell/connector), DVI-I which is digital DVI output, and DVI-D which is dual-link DVI for use with 30" LCD like Apple's 30" CinemaDisplay or Dell's 30" LCD.

Page 21 of the User Manual (PDF) from Uniden NZ's website.

About Equipment with an HDMI or DVI jack
Use the HDMI (High Definition Multimedia Interface) jack when available as this connection is recommended for best quality picture and audio.
If there is only a DVI jack then DVI to HDMI cables are commercially available. DVI only supplies a video signal so connect audio
cable too. If connecting from DVI source to the HDMI1 jack, connect audio to the Audio3 jack. If connecting to the HDMI2 jack,
connect audio to the Audio4 jack. Then go to the Audio Setup menu and select audio input to choose Audio3 or Audio4.

Thanks for your replies.
There is nothing in the manual about connecting your computer. I don't know why they make it so difficult. It's almost like they don't want people who buy LCD tvs to hook their PCs to them. Most of the newer models I checked out didn't have somewhere to plug in the monitor. They all have HDMI, wheras the older ones usually had monitor connections. The salesman seemed to think the HDMI was far superior to DVI. I assumed if you can get adapters that go from DVI TO HDMI there shouldn't be any problem.

"I would suggest contacting Uniden and asking them if the unit will accept an HDMI input from a PC.. "

Uniden is closed until the 8th! I'll try and work out a solution before then. There must be a way. What about if I use the S-video or the other connectors?

zad1: I assumed if you can get adapters that go from DVI TO HDMI there shouldn't be any problem.



That's not necessarily the case however. Contact Uniden and ask them if the unit will work with a PC plugged in via DVI.

Some Plasmas such as the Sumsung models used to have DVI connectors that could be used for PC input. These new models specifically say in the manual that you cannot use a PC via the HDMI input. Reading a few articles online there are a lot of people encountering issues trying to plug PC's into HDMI inputs and it appears with some TV's they will not accept HDMI inputs unless HDCP copy protection is present, something many video cards to not support.

Zad1, I think both sbiddle and I have read the specification.

I'd suggest start with setting lower resolution on PC, and try with DVI-HDMI and see how it goes first. If that doesn't work, perhaps try returning DVI-DVI cable and HDMI adapter, and get DVI-HDMI, although I don't see how this may be the problem.

Uniden's TV manual did make a mention of the word "PC" in regards to setting label on the inputs (check towards the end of the manual), so I take that it is possible to connect PC to the LCD TV.


Next, try with using LCD TV as the only monitor, which you would have set it at lower resolution already, right? (800x600 seems to be a good low resolution, which reason why you can view the Windows XP boot up screen). See if you can get the HDMI input working with picture, then bump up the resolution, one notch at a time. Also, IF this Uniden TV is intelligent enough, it may have DDC information in it for Windows to detect. If so, then it will tell your graphics card what resolution it can support. Sometimes this may not happen, if this is the case, you will need PowerStrip to configure.

Good Luck.

p/s: at least you have 2x HDMIs.

"perhaps try returning DVI-DVI cable and HDMI adapter, and get DVI-HDMI..."
It is an HDMI cable, and the adapter is DVI male, HDMI female. Would a cable that's DVI at one end and HDMI at the other make any difference?
"Uniden's TV manual did make a mention of the word "PC" in regards to setting label on the inputs..."
Sorry, I didn't see any reference to PC in the manual. Whereabouts did you spot that?

Yes, I've spotted it now. On Page 41 of the manual, it does seem to imply you can plug a PC into it.
But does it mean I have to set my PC to a low resolution every time I want to watch some file on the tv? That seems like a real pain in the rectangle.
Why is it so tricky? I thought for sure a modern LCD tv would be better quality than my widescreen LCD monitor I got for $299!

Usually it's the other way around.  Various LCD TVs that I've looked at only support 800x600 or 1024x768 resolution Frown.

Surprising, as you say, but that seems to be the way it is with many LCD TVs.  You would think they could offer flexible resizing options on all LCD TVs by now, but at least for lower-end units, it doesn't seem to be that common yet.

Making progress. Based on the advice you guys gave, last night I gave it another crack (I'm stuck at work today, unlike others).
I found it seems to like 1280 x 720. I get a decent image of the PC desktop. Everything seems a little bit tall and skinny. It's fine for watching video files, but I noticed a faint flickering in the middle of the screen - horizontal lines wavering, just enough to make the cursor blink in and out.
The image is very bright compared to the monitor (have to turn the brightness right down on the PC) and a little bit blurry. Not the greatest for doing PC work.
It also likes 720 x 480. Again, fine for watching a google video file, but utter rubbish from the point of view of doing any work on the PC. It certainly changed my grand scheme of using an LCD tv as a PC monitor.
My next plan is to play with the "Powerstrip" software you mentiones.
Thanks chiefie and sbiddle for the patient advice.

Let me save you from going down that path.

Unless you want to use your LCD TV as media pc display panel (i.e. using Media Centre features from 10'), don't expect to use your LCD TV as your computer monitor. It's not great at that. IF you "must" then you should get Full HDTV like Philips's 37" CineOS line, or Sony's Bravia-X series, which is at 1920x1080. Alternative is, get Dell's 24" LCD monitor with 5 inputs.

We got our Media Centre PC and LCD TV thinking of the same, but the desktop view on LCD TV is less than desire, so decided we'll have TV for what it is designed to do, display tv. And we may get Xbox360 or an Media Extender to connect to our Media Centre PC to stream contents to our 32" LCD TV.

With Vista Home Premium/Ultimate, I read that you can have Media Centre in full display on one screen (instead of windowed), while having an active desktop on the other. But how does the mouse/cursor control works, I don't know.

Our setup now is Media Centre PC with the included 21" HP LCD for day to day usage, and odd occassion of recording tv. TCL Digital Decoder with one output to LCD TV and other to MCE. There's not connection from MCE to LCD TV at all. We have Wii connected to LCDTV via Component cable, and Sony DVD Home Theatre to LCD TV via S-Video. Our Xbox and PS2 both have been "demoted" from our room and on to living room with a spare old TV for my nephew and niece to play when they're here. We hope to "upgrade" our Sony DVD Home Theatre to one that is capable of HDMI output. We're not too worry about HD-DVD or BluRay yet as we don't see ourselves be using that in 2007 or in 2008 yet. But who knows. All we plan to get is either a DVD player/home theatre unit with HDMI output, or Digital Cable TV decoder with HDMI (very unlikely). Ideally, DVD player with HDMI, Digital Cable TV decoder with Component, and Wii with component. mmmm

I have a tv card on my pc and occassionally use Winfast PVR to record shows. I've always watched DVDs on my monitor because I can stick on the earphones and not bother anyone, and I preferred the widescreen monitor, before I bought this tv. I can burn DVDs on my DVD writer and watch google video files. All my music is on itunes and I plug in my ipod to update it.
So I've been waiting for the great 'merger', when the tv and computer just become one and the same.
Most of the time, I'm crawling around the back of the PC/tv plugging in cables (stereo, earphones, etc) and plugging them in again!
Really, the tv just became a bit redundant around my house, turning it on every night at 10.30 to watch the news. (Now we have the LCD tv, though, we'll watch DVDs on it.)
What I can't figure out is, why is a 'Media Centre PC' any different to the scenario I just described? Is it just a piece of interface software? Perhaps you can enlighten me about 'Media Centre'. (If you can't just plug it straight into your tv and enjoy full PC functionality on the tv I can't quite see the point!)
