Computer Is Lagging When Connected To TV With HDMI Cable

Dec 7, 2011

I have a HP Pavilion DV4-1030en. Specifications:

Intel Centrio 2 2,00GHz
4GB ram
nVidia 9200m GS

So, these are giving the main performance to my machine. I have also a nice Samsung D5000 TV (32" ) FullHD. When I connect my Laptop with a TV, computer start lag. It even doesn't use all of CPU (20-25%, while playing 720p video in TV with 10 fps (Fraps)). I've all latest drivers and everything should work. Using Windows 7.

Computer Won't Go Into Sleep Mode When HDMI Cable Is Connected

Nov 9, 2011

I have an Acer Aspire laptop running Windows 7 Home Premium x64.

I regularly connect it to my TV monitor via HDMI cable and fall asleep watching movies (played on VLC or Windows Media Player). I set the computer to go to sleep after 1 hour.

Multimedia Settings are set to "Allow computer to sleep" under "When Sharing Media" in the Power Management section.

Screensaver is disabled. I have overrided my audio driver, since powercfg command suggested it may be a conflict.

If I am playing a movie without the HDMI cable plugged in, the computer goes into sleep mode right on schedule. It is only when I have the HDMI cable plugged into my TV monitor, that it refuses to enter sleep mode.

No Sound To HiFi Speakers When HDMI Cable Connected?

Feb 8, 2012

I have connect my laptop using an HDMI cable to my TV. And from my tv I have connected my two HiFi speakers. When the TV is on an AV channel I have sound coming from the TV and HiFi speakers but when I switch it to the HDMI source channel, sound only comes from the TV and not HiFi speakers.This is frustrating because I want to watch movies on my TV through my laptop and get the feel of some surround sound through the HiFi speakers but it is not working!

Displaying Computer On Tv With Hdmi Cable?

Jan 18, 2013

I have aspire 7745 laptop running windows 7 premium 64bit. I had the video & sound working on the TV via the HDMI cable but it stoped working. Now the TV "sees" the HDMI signal (and receives a low tone) & the computer "sees" the TV as a secondary display in the device manager. but no signal or sound. i have tried many ideas found here and other places on line but no change.

Computer Only Recognizing 2nd Display Via HDMI Cable Intermittently

Aug 5, 2012

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.

Computer Shuts Off Within 5-15 Minutes After Network Cable Is Connected?

Jan 6, 2013

Here are the computer specs of the computer:

Ultimate SP1 64-bit
Xion 600W PSU XON-600F14R-201
Asus M2N32-SLI Deluxe Motheroboard
nVIDIA nForce 590 SLI Chipset
BIOS Revision 1402
NVIDIA GeForce 8800 GTS 640MB
AMD Athlon 64 X2 Dual Core 6000+ 3.15 (15 x 210 FSB)
Muskin 4GB (2 x 2GB) 991587 DDR2-800 SDRAM 5-4-4-12
Koolance EXOS2 Watercooled
OS Drive: Seagate Barracuda ST3500820AS 500GB
DATA Drive: Samsung HD501LJ
NVIDIA nForce 10/100/1000 Mpbs Ethernet
Realtek RTL8187 Wireless 802.11b/g 54Mpbs USB 2.0 Network Adapter

The CAT 5 Ethernet cable network cable is attached to our main Linksys WRT320N DD-WRT router ---> Motorola SB5101U DOCSIS 2.0 Cable Modem ---> Coaxial cable from wall outlet. Another computer is also directly connected to the same router via CAT 5 Ethernet cable and two more computers are wirelessly connected to the same router and none of these three PCs are experiencing issues so this should rule out the router as the culprit.if I leave the computer on (even for hours) with no network cable attached to the computer, it does not turn off. But as soon as I plug in the network cable, the PC will shut itself off within 5-15min.Based on the same scenario as described above, here are the troubleshooting attempts I made without success, except for numbers 4 and 6:

1. Switched to different network cable and router port.

2. Disabled Network Adapter connections in "Network adapter settings" for both the onboard ethernet port and wireless adapter.

3. Ran MSCONFIG.EXE and rebooted in diagnostic mode. Only basic Windows services are loaded. No startup programs are loaded.

4. Rebooted in Safe Mode with networking but could not establish any network LAN/WAN connection. Computer did not shut off!

5. Cloned entire hard disk to another hard disk and switched SATA data and power cables on the same computer.

6. Installed fresh Windows on different hard drive on the same computer. Computer did not shut off!

Out of those 6, only numbers 4 and 6 were where the computer remained on and didn't shut off at all after the network cable cable was plugged in.

No Audio Via HDMI To TV Cable

Oct 28, 2009

I have happily been viewing movies etc from my laptop to my TV via an HDMI cable for the last 2 years. However, I installed Windows 7 and at first I had no audio to my TV via the HDMI cable. I adjusted the settings via the sound icon on the taskbar, playback tab, changing whether the speakers or the Digital Output Device (HDMI), Sigmatel High Definition Audio Codec was the default. Eventually I got it to work.

Today, however it has stopped working again and no matter what changes I make, nothing works. When I right click on the playback device Digital Output Device (HDMI) and choose TEST, I get the message: Failed to play test tone. All sound comes through the laptop speakers.

I went to device manager and checked the driver for the codec and it was up to date. I downloaded all available updates from Windows and my laptops software updates and just now re-installed my sound and video drivers but to no avail.

When I was using Vista, to get the audio all I had to do was plug in the HDMI cable and the sound automatically went through the TV.

Does anyone have any ideas how to solve this?

Optical Cable Recognized As HDMI?

Jan 5, 2012

I have a Windows 7 enterprise 64 bit pc and an Onkyo receiver. I used to have them linked with an aux cable for music. But since I had enough of the bad sound quality I bought an optical cable and connected it. Now I have the problem that my subwoofer gives a lot of less sound then with the aux cable with the exact same settings and music. Also my pc recognises the optical cable as an HDMI cable and I don't think this is right. I can't change any settings either in the sound.

Pc Wizard told me I have this onboard sound card: ASRock SB600 High Definition Audio Controller Pine Technology HD48x0 audio

I just reinstalled Windows7 from recovery discs on my Dell desktop. Sorry, I don't know much about what hardware I am running, but windows7 is a fresh install and everything else works OK. When I plug the HDMI cable from the pc to the tv all I can see is the desktop background with no icons or desktop folders. I can't see any programs either. I do have sound though.

Laptop Not Detecting TV Through HDMI Cable Anymore

Sep 10, 2012

What's been going on with my HDMI port. 2 nights ago I was watching a movie through my Dell Inspiron N5050 laptop through my Panasonic HDTV. Yesterday, I tried to connect my HDMI cable to my laptop and computer, but nothing happened...So frantically I've been searching everywhere and trying what I have so far with no progress...

1.System Restore to earlier date when my HDMI port was working.
2.Toggle Computer/Duplicate/Extended/Projector Only and nothing worked(Also made sure tv was on the right HDMI input)
3.Tried 3 different HDMI cables and HDMI inputs
4.Uninstalled all sound drivers and Display Adapter(Intel(R) HD Graphics Family
5.Contacted Dell and had them try to reinstall drivers
6. Checked BIOS but I couldn't find any enable/disable feature for video.
7. Took battery out of laptop waited for 30 seconds pressed power button to reset.

My Panasonic TV doesn't even show up under my playback devices and when I try and do a dual screen through screen resolution it says another display not connected. I've tried going Intel HD Graphics Control Panel as well...no such Luck! Beginning to think that my HDMI port on my laptop is broken.

How To Automatically Change Audio Device When Inserting HDMI Cable

May 4, 2012

My lapotop is HP Pavilion 9750 running Windows 7 Enterprise (with the latest updates). When I'm inserting the HDMI cable to view my screen on the TV it automatically shows the video, but I have to manually change the default playback from "Speakers" (Realtek High Definition Audio) to "Realtek Digital Output" (Realtek High Definition Audio) so I could hear the audio from my TV and not from the computer.

Is there a way to make that switch automatically when I connect/disconnect the HDMI cable?

Notebook Is Slow While Connected To HDMI?

Dec 3, 2011

today my notebook asus m50vn suddenly started to behave weird. while it's connected to plasma via hdmi, everything starts to stutter a bit, which is very inconvenient in videos.it works like this: 0,5 s of fluid picture, 0,1 s of freeze, 0,5 s of fluid picture, and so on.situation is the same on primary (built-in) monitor and secondary (plasma), as well as on Internet, vlc, potplayer and mpc hc. dxva and cuda won't make any difference, choosing different video renders in player's settings won't do ve already tried to install older and newer drivers (graphics is geforce 9650m gt) computer is 100 % virus free, there is comodo is for on-access security and i've also checked it with malwarebytes, hitman pro, emsisoft emergency kit, kaspersky tdss killer and cce. almost all processes are disabled.it's interesting because there's no problems when plasma is connected via vga.

Windows 7 Freeze While Connected Via Ethernet Cable To Router?

Dec 25, 2012

I have an annoying problem with my pc running Windows 7 Ultimate.Till I connected my pc(which is a desktop without wi fi adapter) to internet using a ethernet cable and a wi fi router I had no problems. After that, randomly, but especially when browsing the internet, the computer freezes and I must restart it.I have to mention the fact that if I connect my pc to internet using directly the cable from my ISP ( a pppoe dial-up connection) everything works fine.
