Re: display resolution through dvi input HELP!

For the record I have a playstation 3 running to tx100 through hdmi to dvi adapter. It does all resolution no probs, including 720p,1080i and 1080p (which tx100 does do smoothly through dvi). My denon upscaling dvd player works fine too. In fact the tx100 looks totally awsome with PS3 games and Blu-ray.

Maybe your dvi lead is the wrong type (i think there are 2 types) or perhaps you could test with a differrent piece of DVI kit in case it's your pioneer causing probs? Hope this helps.

Hooking up projector to laptop with only HDMI port

The PG-F320W has a DVI-I port between the VGA/Component input and the VGA output. You will need an HDMI to DVI cable or a HDMI to DVI adapter and either an HDMI or a DVI cable. If you use the audio input of the projector, you will also need the audio cable between the computer and the projector. (Make sure to disable the HDMI as the audio playback device. In Windows, go to the Hardware and Sound Control Panel. Then go down to Sound and Manage Audio Devices. Click on the Playback tab and check your output device. Click on Start for Windows 7 and earlier, Windows Key + X for Windows 8. Then select Control Panel.) has good prices for most cables. The HDMI to DVI cables are here: .

The manual for the PG-F320W is available here: . See page 21 for the DVI cable connection information. See page 61 for video resolutions that the projector can handle.

I hope this helps.

Sharp Notevision PG-C30XE problem with computer display

There are 3 different types of analog video signal ports on your projector; s-video, composite video, and RGB. Which one of the three are you using to connect your PC to?
The projector's resolution rate is XGA [1024 x 768]
If you are using a VGA cable designed and capable of handling 640 x 480 resolution; then it will not support XGAs 1024 x 768 signal. On the other hand, if the coaxial cable you are using is a multi band one that is capable of supporting VGA and XGA resolution signals, most likely the problem is not with the cable- although I have come across brand new cables that are defective.
Please let me know if this helps or else we'll try another approach :)

It is probably mirroring the screens on your MacBook and the projector. If you want different resolutions and things on each screen, go to the Apple menu, System Preferences, Displays, Arrangement and uncheck the "Mirror Displays" checkbox.

No signal

Hi and welcome to FixYa,

Initially, the "No Signal" error message indicates just that, it is not receiving anything or that the signal it receives is beyond its capacity. With this in mind, pls check:
  • the cable connection from PC to Projector;
  • that the PC is set to display on a 2nd monitor, TV or Projector depending on the capability of the PC's video card (Twin View or Dual View); or
  • as main monitor;
  • lower down the computer's Screen Resolution and/or Screen refresh rate.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Maximizing screen resolution/settings for movies? I have had this since new

Hi there

There is no way you could push it any further than 480p

If you would however like a better picture you can add a scaler like the DVDO Iscan VP30 to the mix and be blown out of your shoes with colour and smoothness of image.

Connecting Projector to High Def Source (e.g. PS3 HDMI)

That projector supports M1-D also which is the digital side of the M1-DA... Anyway, they sell cables that are M1-D to HDMI to which you can hook directly to the PS3. They are decently priced too, less than $20. I know this thread is old, but I came across it due to an issue I am having with my xb31, broken color wheel. Trying to find parts...

LP 640 projector not able to display 1080p

Hello, The LP640 will NOT down-convert 1080p
1080i is the max it can down-convert.

As far as the DIGI input, it is not DVI... It's a proprietary
InFocus format they call M1-D P&D and is NOT HDCP compatible. I have several LP640 manuals, some quite old and none of them claim that 1080p is a valid resolution. interesting that your manual says it is... very odd indeed.

Good Luck!

DVI Digital out of range

It probably means the frequency is to high. Whether Windows, Macintosh, or Linux, you will need to lower your frequency. 60hz is the best for LCD, DLP, & Plasma. The resolution will be better set at 1024x768 as well.

DVI will not recognise now ?

Presumably, you're going directly from DVI port on computer to DVI port on Z2?. Here is a Q&A list based on all the possible sceanrios for this hook-up...

Q1: Is it DVI-D or DVI-I (with unencrypted DIGITAL output from graphics card)?
A1: Choose 'Input 2', then 'RGB(PC Digital)' on Z2.

Q2: Is it DVI-D or DVI-I (with HDCP-encrypted DIGITAL output from graphics card)?
A2: Choose 'Input 2', then 'RGB(AV HDCP)' on Z2.

Q3: Is it DVI-I or DVI-A (with ANALOGUE output from graphics card)?
A3: Choose 'Input 2', then select 'RGB(Analog)' on Z2.

After making sure the correct 'Input 2' is chosen to match the signal coming from the card's DVI port, make sure your card is outputting a suitable screen resolution that the PLV-Z2 can display correctly, e.g... 1280x720 (native, and preferable!); 640x480; 800x600; 1024x768 (choose this if you don't have 1280x720); 1280x1024, etc. Also, if you have multiple refresh rates availble for the resolutions, choose 60Hz.

You should end up with an image.
