22" Sceptre LCD monitor DVI to HDMI problems.

I have just purchased a 22" Sceptre LCD monitor which I have connected from its DVI port to the HDMI port on my Scientific Atlanta cable box. When both units are turnrd on, there is no pictue on the screen, and the picture will flicker on and off for a short time and then just stay off. If I leave the LCD on for some time, (maybe an hour or so?) the picture will eventually come on and stay on. I have duplicated this several times. Is this a buggy monitor set up? I am at a loss.........

SOURCE: Sceptre monitor will not return from idle.

The only workaround was to not use the DVI cable but to use the old VGA cable. You still get the same resolution.
I have a different ATI board, so I'm thinking it's an ATI+Sceptre on DVI input bug. Anyway, use the VGA cable, it'll work.

Have you tried any other monitor connected to your computer since your current problem? Check your connections, make sure your VGA cable/DVI cable are in good condition. If none of that works try to RMA it to sceptre if your still within the 1 year period.

I am working on one of these for a customer. Found leaky cap on 5 volt power supply. replaced it, still no backlight. Looked at the inverter with an o-scope and it runs for a few seconds then shuts off. I hooked a ccfl across each of the transformer secondaries on the inverter and it lit up! I believe the problem is failed ccfl units. There is plenty of voltage there to light them up, I have an rf burn on my thumb to show for it. I have not looked at the ease of dis-assembly of the display to replace the backlights. It does not look easy.

How to connect the HDMI Cable from monitor to Computer which has no HDMI ports?


Hi there,

You need a purchase a new cable. I assume your HP pavilion is under 5 years old. And you should have a white DVI port in the back for a monitor. If you do have that connector, then all you need is a DVI - HDMI cable, make sure the DVI will be to the computers end and HDMI to the monitor.

for example this cable:

I need to connect a VGA dell monitor my Toshiba Laptop


HDMI is digital
VGA (the 15 pin connector) is analog.
If your connector has the digital to analog interface it should work, but likely it does not have that chip and thus will not work.

Your description of the problem tells me it may never work as you have it connected. Possibly it might be that the monitor is required to be powered on before the laptop is booted, but that only works in some cases.

I have also seen some work if a 2-step connector is used.
VGA to DVI connector, followed by DVI to HDMI connector.
DVI was the step toward digital that came before the HDMI standard was implemented and was only partially digital. DVI and VGA do not carry control signals nor audio. HDMI carries both those as well as the video.

YMMV but I think it would be cheaper and more efficient to actually purchase a monitor with a digital input (HDMI or DVI).
Without the digital/analog converter interface a digital output device (your laptop with HDMI out) can never operate an analog device (your Dell monitor with VGA input).

I have a dell dimension 3000, bought a new HP 2310E monitor with 3 ports. DVI, HDMI & display port. Told to buy a cable with VGA to connect to dell and DVI to connect to HP Monitor display port....


Hi sshorne9780,

I see that you are having a check input error on the Monitor/LCD that your are connecting to your Dell tower, please see steps below.

  • On your HP 2310E make sure that your HP is set to the input/source that you are using and make sure that you only use one type of video cable for the issue.
  • I see that you mentioned that you have a VGA cable and a DVI cable, you can only use one type of cable for a video connection.
  • VGA would be the Blue tipped cable connecting to the tower and going to the LCD monitor.
  • DVI this is a black cable connecting to a white port much bigger than a VGA port and is rectangular in shape unlike the VGA
  • moz-screenshot.pngmvincentc_34.jpg
  • and on your LCD monitor check the input type to see video from the tower.
  • everything seems to be OK you just need to change the input of your LCD monitor for the video to show up on the screen.
  • also if you are using HDMI for the video u will need to change the setting of your Audio and set HDMI as the Default to have Audio come out from the HDMI connection together with video, the HDMI viedo will automatically be detected as long as the LCD monitor's input is set to HDMI.
I hope that this will able to help resolve your concern.

Thank you for choosing Fixya,

How to connect laptop to my coby tv?


Check if you have an HDMI or VGA/DVI port in your LCD TV and LAPTOP. Once you have those ports you can just buy an HDMI cable or VGA/DVI cable to plug it to your laptop.

How do you connect LG W2261 VP Monitor to HP Pavilion 6310uk Desktop


The computer has VGA, DVI-I (dual link) and HDMI ports. The monitor has VGA, DVI and HDMI but only came with a VGA cable. Some computers have recently come with shielding covering all of the ports except the one that is currently live. Thus, check your hardware; the computers I've seen with only one active port, the HDMI port was active before resetting the video options. So get an HDMI cable (it will provide the best signal in addition). If the DVI-I port is currently live, you should get that cable as well and then change the settings to enable the HDMI port.

I hope this helps.

(you do not need to get the super-expensive cables; the low end ones will be fine. However a single link DVI cable is not the same as a dual link cable; sometimes using the wrong cable leads to no signal to the monitor.)

I am trying to connect a Sceptre monitor


Will the monitor work on another computer? Will the computer work with a different monitor? Are you connecting the vga port to vga output on the video card or the dvi input to the dvi output on the card. You may need a video card with hdmi output.

My monitor says cable not connected


If it like my monitor, same hookups as yours, then when you want to use the hdmi port you need to disconnect the dvi cable. The monitor cannot read from hdmi & dvi when both are connected, Try this & see if your PS3 works. Good luck
