Help with computer
« on: January 15, 2017, 07:40:22 AM »
For you computer smart people.

Laptop worked with HDMI to TV.  Installed the app for SlingTV.  TV no longer recognizes signal from computer via HDMI.  Cable is fine, still use it for the bluray.

I think the SlingTV application is interfering with the HDMI cable.

Anyone else have this issue?  Thoughts?  Intelligent suggestions?

Hit Win-P until it says "extend" or "projector only"? Not sure what your setup is, how much of a non-techie you are, etc. You're on the right HDMI port I guess.

Nothing should interfere with the cable. Only video card drivers.

Did the win + p.  Didn't work.  HDMI works fine with dvd player.  It used to work fine with the laptop too.  The only recent change I made was to install the SlingTV app.  Only have one HDMI port.

Hold the Windows key down and tap p, you get a box in the middle of the screen, right? Then keep holding Windows down and tap p until it selects the right thing?

The TV has only one port? And you're running Windows Vista or newer?

Sure, try uninstalling whatever you installed. Could be a wire cracked in the cable that touches when in one position but not in another. Could be a screen res issue, but HDMI should detect that.

Try updating your graphics card drivers.

Assuming you're on Win 7 or so, if you right click on the desktop and go 'screen resolution' do you get both 'monitors' showing (ie, your laptop screen and the tv)?

New Lenovo laptop.  Win 10.  Win + P lets me select correct mode but doesn't make HDMI out work.

From a google search, this has happened on different types of computers.  I've reset to the factory settings and uninstalled the Sling TV application.  BTW, I don't get OTA TV and I cut the cord with Direct TV (200 stations of crap).  Now I only have 30 channels of crap for $20 if I keep Sling.  On a 7 day free trial now.  Not impressed).

Anyway, if any of you have had HDMI out problems (TV says no signal), weigh in with your fix.

Go to any computer shop; ask if you can try your laptop and their hdmi cable on their monitor; and then your laptop and your hdmi cable on their monitor.

Anywhere - your library, university, office, anywhere that has a different screen and a different hdmi cable.

As I stated much earlier, the problem is not with the HDMI cable.

Individual wires can break. It could be that, in a certain position, the cable is fine, but when bent into a different direction, it is not. It will, presumably, cost you all of 30 seconds extra to test it when you do the other test. It could also be that the cable end or port is loose; you may 'see' or feel that when directly comparing with a different cable.

It is the sling app - the copyright protection is in the HDMI cable - you can't sling over HDMI.

HDMI cables can be temperamental, especially with HDCP encrypted content, and I suspect that you can still potentially get HDMI out from your laptop when the SlingTV app isn't running. Try a "higher quality" shorter HDMI cable. It's also theoretically possible that depending on how old your television is, its own HDMI in port doesn't support the HDCP version that your laptop and SlingTV is spewing out. Hard to tell without greater details, but it sure sounds like that's the sort of problem you're running into. Try giving this a read.

This is why DRM can really stink... it rarely stops the activities by those its purpose is intended to prevent, and frequently breaks usage for people not intending ill will.

HDMI cables (plural) are fine.  They work with the TVs and blurays.

Based on a google search, it appears there are a lot of people having this same issue with Windows 10 and HDMIs.  So far, no Microsoft fix.  Appears to be driver related.
