View-sonic LCD Monitor Not Recognizing HDMI Input Signal?
Sep 2, 2011
ive got a problem with my new viewsonic vx2753mh-led monitor. its got 2x hdmi inputs and one vga.the vga works straight off the bat, but whenever I try and plug the hdmi in it just says no input signal detected and goes black I noticed in device manager that this was installed as 'generic non-pnp monitor' so after jumping through some hoops i managed to install the driver as 'viewsonic vx2753 SERIES' anyway this doesnt seem to have made a difference. still no input through the hdmi.I have tested to cord on my samsung tv and it worked fine so it can't be a problem with the cord or the graphics card....just some general info that might be of use:
windows 7 x64
dual monitor setup
the graphics is integrated on the intel i5 chip my display adapters in device manager says Intel(R) HD Graphics Family.it has a dvi out, hdmi out, and vga out.

Starting today my computer has been randomly turning itself off, although running lights are still on, and the computer sounds as if it is still running normally.Essentially what happens is that it crashes out, the monitor says input signal lost and then nothing happens. First two times it crashed whilst using Photoshop. Third time I installed a program to monitor the HDD temp. It was running just over 40c when it crashed again (had a low end game running to see if the HDD temp would rise). I waited 30 min before turning the computer on each time.Opened the case to check for any build up of dust, it seemed fine.I have also checked that all the cables are plugged in correctly.Also definitely something wrong, because holding down the power button didn't turn it off. Had to turn the computer off by the switch at the back of the computer.Only thing new with the comp today was updating Microsoft.Net framework, a few hours before the first time it crashed.

I've just built a new computer with Windows 7 and a gigabyte brand radeon HD4890 and have been having the same issue as some other users with regard to the over/underscan.
I managed to correct the inch or so of unfilled space when displaying the desktop by using the under/overscan utility in CCC (thanks to info on this forum ^_^) but found that the problem still exists when I ran my first full-screen applications.
I installed, updated, and ran Spore: Galactic Adventures to take a look at how my system was going to handle everything, but found that the dreaded inch was back. The really odd thing was that when I switched Spore to windowed mode, the inch had gone and I could maximise to full-screen. Of course, the window header and taskbar kind of detract from the game, but this isn't necessarily an issue for Spore (which can hardly be described as immersive).
I am, however, concerned that this issue may pop up in other games where the window header and taskbar will detract from the game (if it operates well in windowed mode at all).
I plan on investigating further later today, possibly in the direction of motherboard and chipset drivers, but also testing with other games.

i have an Alienware M17X R3 with an HDMI INPUT which i can plug my xbox 360 into and play it through my laptop monitor. Is there any software that will allow me to use the HDMI IN as the primary video input, in oppose to the actual desktop screen? i tried using a few free softwares in which it records the "HDMI IN ON" message that shows up, but when it goes away and when I see my dashboard, the recording software sees my desktop image. i do not have a capture card, nor do i want to use one. i simply want to use a software (if there is one) to capture the HDMI IN on my laptop.

This is becoming a pain in the ass. I am using HDMI through my AMD 6850 to my LG TV for audio and video. It has been working fine(no audio problems) for about a year.Just recently, with no hardware or related software change I can think of, now, if I switch the input on my TV(for example go to HDMI1 to watch TV and then back to the PC) there is no audio. It becomes disconnected, I have reinstalled and tried using the AMD HDMI driver and the Realtek(my chipset) HDMI driver. When I switch inputs, sound manager shows HDMI as "not plugged in". The only way to fix it is to unplug the cable and plug it back in while staying on the PC HDMI input

When I connect my PC to my TV Via HDMI Cable, my TV does not receive a signal. When I check in Control panel>Display>Resolution, My TV hasn't even been detected. My TV is an LG 50", Card is a GTX580, and my OS is Windows 7.
Also, when I connect my laptop to my TV via HDMI (Also on Windows 7), It is instantly recognised and automatically displays, so it has to be an issue with the PC itself.

I just bought a Lenovo v570 laptop with vga and hdmi output and I cannot get the hdmi to output to my tv. The tv is a vizio 47" 3d LCD and the laptop is running windows 7 home 64bit. I have tried windows graphics drivers, lenovo drivers and intel drivers. To me there is not much difference between them but who knows. The laptop will output to tv using vga and it will connect to an LG 42 inch LCD at my work using hdmi, just not to the one I have at home. I have tried everything that I can think of as far as settings go and on my tv as well. Nothing changes whatever I do. Does anyone know of any hardware compatibility between some vizio tvs and windows 7? I have seen one on the compatibility website for windows but it was not my tv. Mine is not listed. The model number for my tv is E3D470VX. Not sure what else to try. Next I guess I will call Vizio to see if they can work out the problem. Lenovo support doesn't know.

Sony notebook with HD AMD6630 M. HDMI port not giving signal to TV. When I rollback the Intel Gaphics driver the HDMI signal comes alive but then goes dead after reboot. I have been trying to solve this for 2 weeks without success.

This computer is running an ATI Radeon HD 2400 Pro. It does support dual monitors...(I've had dual monitors active on this card before, but never on Windows 7.) But since installing windows 7, I can't even get it to detect the second monitor. I want to run the setup with the CRT as the primary monitor and the HD as the secondary.

I have done some searching but to no avail. I have tried everything I can find/think of with absolutely no luck.
I have a brand new Samsung LN46B750 which I have connected to my desktop for use as an HTPC. VGA works fine, but I would much prefer to use a digital connection. SO, I have an HDMI <> DVI adapter and a monoprice HDMI cable connecting my GeForce 6800 to the HDMI/DVI port on the HDTV.
I have tried 182.5 and the latest Nvidia drivers as well as the generic Windows 7 drivers. It's all the same.
Everything works fine in the OS so long as I make it past the Windows splash screen. And unfortunately, that never happens. I believe that the problem lies in the auto adjustment of the screen when 7 starts loading. (If I boot without the TV connected, and then connect after the splash screen has loaded, everything is perfect.)
Is there any way to disable the auto detection/adjustment of the TV and just have the OS always boot into 1920x1080 @ 60 Hz. I am really tired of the blank or black screen every time I reboot. This is a terrible bug with Windows 7 or EDID and it needs to be fixed now Microsoft!

I am pretty decent with computers but not an expert. I am having a little trouble with my home theater PC display flickering. My video card is a Radeon HD 6900 and the drivers are up to date. I have the HDMI out of my PC going to an Onkyo 7.1ch HT-R590 receiver and it's output going to my LG 42" TV. My OS is Windows 7 Ultimate X64.The system used to work perfectly fine but over time the display started to flicker at random times. I tried to hook my PC directly to my TV and it works perfectly fine, so I am 100% certain the problem is in the receiver. I did a bit of research and it appears to be a problem with my receiver over heating.
Now, if I run my HDMI to my TV, I cannot use 7.1ch surround sound. (Even after playing with Audio Return Channel) If I run optical to the receiver, my video card only puts out 5.1ch surround sound for some weird reason. So I did the next obvious choice, I ran a DVI to HDMI to my TV for video and HDMI to my receiver for audio. I thought it would trick it into thinking there was two displays but this does not work, I do not get audio. was wondering if you guys knew of any utilities that would allow me to output audio on one HDMI stream and video on my DVI port. I did a lot of looking around and it looks like DMCA calls for HDMI to be encrypted and you can't separate the stream. Or would I just be better off getting a separate audio card to connect to my a/v receiver

I have an HP Pavilion Elite HPE machine, Windows 7, Radeon HD 5700 Series graphics card, connected to an Acer monitor and HDTV. Here's details on my setup:
My Equipment | Building a Home Theater With Your Office PC
My problem is that even though my HDMI cable's plugged into my Radeon graphics card, sometimes the PC only recognizes the Acer monitor and not the receiver (that's connected to the HDMI cable and my HDTV). So I end up having to plug and unplug the HDMI cable several times (sometimes 10+) before it recognizes the HDTV/receiver connection. Is there any setting that would favor the card/PC recognizing the HDMI cable more frequently? I've heard it's a handshake issue, and that maybe using a different type of cable would work. But wondering if there's a setting I could use before switching out cables.

We just bought a Hp Pavilion p6-2133w, we hooked it up to a sony monitor, we had to hook them up with a adapter that takes the dvi-d from the computer and adapts it to vga for the monitor. The problem is the monitor doesn't act like it is reading the signal.

My new PC with windows 7 won't detect my old Acer v243w monitor. I was hoping to use dual monitors, with this monitor connected via vga into the motherboard and my other monitor connected by DVI into the graphics card. The graphics card I am using is a Radeon HD6870. It has DVI slots and an HDMI slot but no VGA slot.
Even when the Acer is plugged into the motherboard by itself using VGA it does not get detected then either.
Is it simply a case of getting a lead which will convert my VGA lead from the Acer monitor into a DVI output which I can then plug into the graphics card?
Or perhaps there is a way of enabling VGA support, maybe via the graphics card or something? It seems odd to have a VGA socket in the motherboard if it is not going to work.

Alright so it worked when I left to go pay a bill. Come back and it has no signal. I tried the PC on my TV to see if it worked and it does no problem, so I know the PC is not at fault. Tried a DVI cable and a VGA. Tried restarting and powering off everything.

i read the manual and followed the instructions as best as i could but when i was done and hit the power button, everything turned on except i I'm not getting any signal on my tv. Im using an HDMI cable i'm guessing thats the problem but I'm afraid to go back and try to fix anything. I also noticed a red LED go off as soon as i hit the power button but it never lights up again. (Only once) I think its my motherboard. Also, i tried turning it on about times and the last time i turned it on, my fans connected to the motherboard were no longer turning on. Im afraid i might've burned my motherboard. Here are my specs:

I have a eMachines ET1300-2 (yes, I know, emachines aren't great) running Win7 Ultimate.Specs: Newegg.com - eMachines ET1300-02 18.5" Desktop PC Athlon X2 4850e(2.5GHz) 3GB DDR2 160GB HDD Capacity NVIDIA GeForce G100 Windows Vista Home PremiumA family member shut it off last night but this morning it started once or twice but stopped sending signals to the monitor part way through each time. The other times I started to run it, it doesn't display any BIOS or anything, and it doesnt seem like anything is runnin except the fans and lights.I got it into safe mode initially at one point, but again, the signal to the monitor cut out and I have no idea what happened after that.Each time I power-button-ed it off.Things were running fine until recently; I did install AirDisplay (forgot there was no wifi - I'm used to my laptop which does).I think it is expected, but I tried to put in the recovery CD to boot from CD, but, of course, nothing displayed.

I just upgraded my AMD catalyst software to 12.4 on my HTPC. Been noticing that when I am viewing via my Sharp 19"LED TV I get signal cut out after about 20 minutes. I notice this when my screen save comes on in WMC. It eventually craps out and I get "no signal" messages on my screen. It comes back if I simply click on the mouse.This never used to happen before. I could leave the HTPC on over night and simply turn the TV monitor off. When I would turn the monitor on in the morning, the Desktop would be visible.Are there new settings in 12.4 that could be causing signal cut out (i.e. like an energy saver option)?

I am experiencing a very disturbing issue with my newly installed ATI 4870 and my Windows 7 RC (7100). Prior to installing this card I had the following setup, which worked flawlessly.
nvidia 8800gt
intel p35 chipset in the motherboard
Samsung a656 40" LCD connected via a DVI to vga connector.
When I got my 4870, I uninstalled the nvidia drivers,rebooted, installed the latest (9.5) ati drivers and rebooted.
Then, I got a no signal in the monitor at the windows login screen.
Mind you, that when I (dual) boot in Vista, using the 9.4 drivers, everything is fine.
Things that I tried:
1. Creating a new monitor.inf file (located at the windows folder) using info from a post in this forum.- This should not make a difference, since I was using the same monitor.inf file in the same windows 7 installation, whitout any issues before I installed the 4870.
2. Changing the ATI .inf file to include only one resolution for the r7x cards 19 20 10 80 00 00 00 60- I think it sould be a refresh rate issue, since the vga port of the TV supports many resolutions, including 1600x1200 etc.
- It could also be an unsupported resolution, if the ATi driver cannot detect the monitor correctly.
3. Installing the windows 7 default ATI driver.
Things that I noticed:
1. I can login only in safe mode.
2. Low res mode (640x480) gets me to the login in screen, but as soon as I input my passowrd, I get no signal.
3. Changing DVI ports in the 4870 (it has 2)
Does anyone have any ideas?
