Hello~

I am going to throw my question into here instead of making an entirely new thread. Maybe that's best. If I don't get responses here I will make the new thread I spose.

Anywho, I purchased a 46" LCD last night.

http://www.newegg.com/Product/Produc...82E16889253209

I will be using this LC for no only a TV but also for console gaming and more than anything a PC Monitor. I would say 50%+ of the time it will be utilized as a monitor.

I have read through some of the threads here but I am inquiring about the most efficient and productive (video quality wise) to connect the PC to the new LCD.

The PC I built myself. It is an EVGA x58 SLI motherboard w/ a Intel Core i7 920 processor overclocked to 4.2GHz. For video, I am running 2 EVGA GTX 275's in SLI. The only output on those cards, is DVI.

The new TV does NOT have DVI. I am *assuming* the most logical way for me to connect the two will be to simply use a DVI -> HDMI adapter. I don't have the SPDIF cable connected for the HDMI sound but I will be utilizing my 5.1 speaker setup currently connected to the PC for sound anyways so that's a non issue.

Any help would be appreciated, and thanks!

You want something like this cable:

DVI = HDMI (without sound). The digital video portion is the same.

While I don't have one of those cables; I *do* have a couple of converter plugs with some HDMI cables.

http://www.newegg.com/Product/Produc...-832-_-Product

Like those - This would be the same as the cable you linked to, or should be. Correct?

Not really. The converter plug would plug into your TV fine then you could use a DVI cable between the converter and your video card. If you try to use a HDMI cable the sex of the connections would be wrong.

Default HDMI sometimes work sometimes doesn't, please help.

Hi, I hope someone can help because I have a problem that's been driving me crazy for almost a month now...it's a bit long but interesting (if you’re a computer geek like me...).

I have a laptop (HP Pavilion) and bought a new Philips 8404 LCD TV.
First day I got the TV I hooked up the laptop using HDMI-HDMI cable and immediately got a perfect picture on the TV. Nice right? but only for 1 day. After I turned off the TV or restarted the PC or something, it stopped working. The PC still recognized the TV as Philips FTV, and I could still set dual monitors and even single display on the TV, but no picture - all I got was "no video signal".
I tried uninstalling and reinstalling NVIDIA drives, re-installed windows 7, nothing worked. Then I read something about EDID (a code your TV is sending to the PC, if it's wrong it could cause problems) so I downloaded a software called "PowerStrip" which enables you to create custom resolutions. After installing it and choosing a preset resolution - voila, it worked! again I got a perfect picture with sound on my new Philips hdtv.
It worked for a week(!). and then suddenly it didn't
again, "no video signal" on the TV and NVIDIA control panel recognizes the TV (however saying it is not HTCP compliant, when it worked it said it is). So again with uninstalling reinstalling nvidia drivers, didn't help, tried uninstalling "PowerStrip" so I could re-install it, but I didn't have to. The second I uninstalled it, it worked! I got a picture. yes, by uninstalling the same software that helped me get it working, it worked again. but as you may guess, only for a couple of days, after booting or unplugging the cable, it stopped working.
Now I can't get it to work no matter what I do. I know that there are some issues with Philips and NVIDIA, and I suspect it has something to do with EDID or other handshake between NVIDIA and Philips, but I tried everything and I don't know what else to do. I tried also deleting the monitors from the registry and manually changing the NVIDIA inf files - nada.
But I do know that there is a solution, because sometimes it DOES work. I know that the HDMI cable is fine (works perfect when connected to my XBOX), that the HDMI input in the TV is fine (again, works with my XBOX) and that the HDMI output on my pc is fine (connected it to 5 other LCD's, got a picture the second I connected the cable).
So anyone? any ideas? something?
this is really driving me nuts
I think a solution for this will help other people as well. for sure the people with Philips-NVIDIA issues (there are many of them...) and also to people getting HDMI periodically working.
Many thanks if you got this far reading this (sorry I know it's long...) and anyone who can help.

This is an often reported problem that indeed is due to the EDID. Most likely your Phillips is not responding before the PC times out. They make a box that memorizes the EDID of the monitor or HDTV and has it available for immediate reply to the PC. Here is info on the DVI version: Got HDMI/DVI Connection Problems?

They now make a HDMI version also, so you can search amazon for that version.

So glad to find this thread .. hope someone can help me!

I have this TV, that has been used for a computer monitor for the last 2+ years: LG-60PC1D-60-inch-720p-Plasma (I can't post links yet)

I've used several different computers with the TV, and never had a problem with the display ... plugged in through an S-video and all's well.

Until now.

I recently purchased an HP G60-535DX and connected the laptop to the TV via HDMI cable. The display on the TV is not good. (I'd describe it as looking like a tie-dye shirt) I've tried adjusting settings on the laptop & the TV with no luck whatsoever. I think I'm in over my head here. Help!

Default More PC LCD Issues...

Hello all, new to this forum so sorry if this has been covered elsewhere.

I have an LG 42LH3000 LCD TV that is good for 1920x1080p. I recently also bought a Packard Bell iExtreme M3720 but I am have some trouble in getting the two to talk to each other.

Firstly, here's the PC spec:

Nvidia Gefore GT220
Vista 64 bit
4 Gb RAM
Quad Intel Q8300 Processor

The PC has an HDMI output and so thought it would be as simple as connecting the two. It detects something is connected, then I get a blank screen saying 'no signal'.

On speaking to the supplier and to LG, they both came to the conclusion that the problem is with the TV's HDMI card and needed service. In the mean time, I was able to connect the two with a VGA cable was able to make the system run on the TV at 1080p (albeit with a little overscan). I could get sound through my component audio system so that wasn't a problem, and ran like this for a while with no issues.

Then, I updated the graphics card via Windows, and all of a sudden I started to have some problems with running games at full screen. Assuming it was the update (the driver had been updated), I rolled it back. That day, LG came over and replaced the HDMI card - however did this not cure the HDMI problem, and now I cannot get 1080p resolution back through VGA! I can still use the TV but only at lower res and the picture is not nearly as clear. The NVidia control panel seems to have lost the HD resolution options - perhaps it is now not detecting it is an HD TV?

I've noticed in device manager that the TV is being detected as a 'PnP generic monitor' - is this normal or does this support my theory?

I've since updated the graphics card drivers with no success, and reconnected my old LG montior via DVI to try and resolve the issue. On the Nvidia panel I can switch between the two and for some resons it gives HD options for my monitor (even though this is not HD), but not the TV

I'm completely out of ideas. Can anyone help? Sorry for rambling...

Default How to force 1080p?

Hello everybody.

I have a 32" toshiba tv (32RV525Rz) that has a native 1080p resolution, and an eee pc 1005HA running XP that has an intel integrated express graphics chipset. I used to have a 1080p 24 inch viewsonic (VX2433wm) monitor and I used to output 1080p to it via VGA. The toshiba isnt supposed to support 1080p via VGA. it maxes out at 1280 x 1024 and if i choose anything above that it scrolls to show the rest. HOWEVER there is a way to make it output at 1080p pixel per pixel and that is to connect the viewsonic, set it to 1080p and then unplug the cable and plug it to the toshiba. I dont have the viewsonic anymore so i need a way to spoof the monitor EDID or whatever to make the laptop output a signal equivalent to what it outputs to the viewsonic. powerstrip doesnt seem to be doing anything as it doesnt support custom resolutions with intel chipsets.

Thanks.

You said you "updated the graphics card via Windows", then said you updated the drivers???

What did you mean by updating the card via Windows? Was that a bios upgrade? If so, and that caused the problem, you may not be able to reverse it.

If all you did was upgrade drivers, then it only makes sense to try to restore the system back to the drivers used when it was working.

thanks for replying lsilvest,

No BIOS updates, I only updated the driver as it was offered as a Windows update. As soon as that problem came about I rolled back the driver, and I can now play games in full screen at least, but this didn't solve the HD problem. As it is now I can still use the TV but only with a VGA cable and at a maxiumum resolution of 1360 x 768, and the graphics card still doesn't seem to pick up that it's an HDTV.

I've run into similar problems before trying to rollback drivers - they never seem to return to the previous state exactly. Seems like you only have 2 options. Just wait for the HDMI fix or reinstall the system with the driver that worked.

For future reference, I don't mess with drivers unless it is absolutely necessary. And then, I always try to use the vendor's site with drivers they have checked out with their card (if possible) instead of generic nVidia or ATI drivers.

Default HDMI Out from PC to HDMI In on HDTV?

Apologies if this has been asked and answered.

Equipment:
- Gateway PC with ATI Radeon HD 3200 Graphics, HDMI Output slot
- Sony 40" HD TV 1080p with an RGB Input Slot (and also component inputs available.)

The TV manual says NOT to hookup PC to TV using HDMI (I don't know why) but to use the RGB input...but the PC only has the one RGB output that goes to the monitor. (I have 2 HDMI inputs into the TV but they are taken by the HD Cable Box and the PS3).

Question: I want to stream HULU and other internet videos to the HD TV. I only need VIDEO because the PC is already connected to my JVC receiver. What is my best option to get good, compatible video to the TV ?

One of these days I'll put together a good all-encompassing home theater...but for now, I need to piece meal.

THANKS for your input/advice!!

I also have no idea either why the manual says this - I have a plasma and LCD and both are quite happy with HDMI from a PC (neither are Sony, though). The PS3 works, and that's essentially a PC, in fact, so is the HD settop box. Then I'm not a Sony engineer.

Anyway, here are your possibilities:

1. Ignore the manual and try the HDMI to the TV- worse that can happen is it doesn't work . If it does work, you can get a switch from Monoprice to give you an extra input to the TV.

2. If your monitor has a DVI input and your PC has a DVI output, use that and then run the VGA (which I assume is what you are referring to as RGB) to your TV.

3. If your monitor does not have the DVI input, but your PC has DVI out, you can use a DVI to VGA adapter for either the monitor or the TV. Or, monoprice has a DVI to Component adapter for ATI video (not sure if it will work with your onboard, but might). The adapter would be better if the TV limits the VGA input to 720p as many do.

4. If none of above works, buy an inexpensive video card that has the connections you need and use one of the above solutions.

Default Any random laptop to Viewsonic projector

We installed a projector each of a customers two conference rooms.
In both cases, we utilized both VGA inputs on the projector.
VGA 1 has an vga cable that run through the drop ceiling, down a wall, and under the conference table to a faceplate recessed into the table top.
VGA 2 has a vga cable that runs through the drop ceiling and down the wall to a face plate in the wall.
Neither cable is longer than 40 feet.

Until recently, there have been no problems whatsoever.
Customer would connect laptop to one of the available ports in the table or on the wall and turn on the projector. The projector would auto-search, find the laptop, and display the signal from the laptop.

Now they are complaining of 2 things:
1. Projector will not find laptop video signal.
2. Projector will find laptop video signal, but continuously switch between searching for and displaying the signal as if it cannot completely latch on.

Trip 1 to the customer site:
I took my laptop to troubleshoot.
I have a newly purchased Gateway NV78 with Mobile Intel(R) 4 Series Express chipset.
Plugged in my laptop to the vga connection in the conference table.
Viewsonic projector detected the signal from my laptop, and my laptop discovered the projector. However, Problem #2 was present. The projector would not stop switching from seaching for and displaying the signal.
Same situation from the vga port on the wall!
Fearing my cables were bad, I bypassed everything and connected directly to the projector with a standard 5ft vga cable.
Suddenly signal was perfect.
I went back to the port in the table and signal was perfect, as was the wall.
I tried the customer's laptop, and it worked properly as well.
I told customer that the projector must have been hung up in some way but that I was not sure why putting a shorter cable on it fixed the problem.

Trip 2 to customer's site:
Customer was complaining that the projector would not display anything at all.
I confirmed this with one of their dell laptops. Projector would not display anything, and laptop could not see the projector.
I plugged my laptop in, and it worked perfectly.
I tried their laptop again..... nothing!
I tried their laptop on projector #2 in conference room #2 and it worked perfectly.
Went back to Projector #1 in conference room #1..... still nothing!
My laptop at this point still worked well with the projector.
Bypassed vga extension and plugged customer's laptop into the projector with a standard VGA cable and it worked!
Went back to the port in the table and suddenly it worked!

So I guess my question should be:
Why does the viewsonic PJ559D often times have to be reset by using a shorter cable before it will sense input or allow itself to be detected by a laptop connected by a longer cable? Keep in mind the cables being used are shorter than 40ft.

I'll be happy to provide additional info if it is needed.

Thanks,
chris

BTW,
I've considered a VGA amp.
I could also go with a set of vga over cat5 extenders.
Both of these options are costly to the customer

But what still gets me is the sequence of events.
Inevitably it works in the end:

1. with long cable.... doesn't work
2. switch to short cable.... works!
3. switch back to long cable... still works!!!!

Seems like it would either work or not with the long cable...
I expect it has to do with some sort of handshaking issue like a lower db is used during the sync phase.

If anyone out there knows the skinny, I'd sure love to be enlightened.
