Complicated problem with hdmi cable

Should i just disconnect hdmi from monitor and put it to tv in order to work?

If i remember correctly i brought it because I couldn't start pc properly,just wouldn't load and they brought it back to me and said the problem was in dust that covered it. And about 2 hdmi connections u are stating is impossible,you're probably right,i dont remember exactly but i think my monitor had a different cable or something like that before they brought it back,im not quite sure,i just remember that i couldnt start watching on my tv until i enable intel on device manager and i disabled it when i wanted to get back to pc. Here is a closer picture of those ports,I guess u re reffering to this : View image: 3 .


And thank u so much for your help,I'll buy that cable in 2 days and hope it's fixed :)

I confess I still don't see evidence of the Intel on-CPU graphics for you to even possibly be able to enable or disable. Device Manager only shows the nVidia GTX 660 in Display Adapter.

But your description further suggests you never actually watched BOTH TV and used your PC/monitor at the same time, simultaneously. It sounds like you have some method of doing one or the other, and switching back and forth through some enable/disable of Intel Graphics in Device Manager to accomplish that. From your screenshots I just don't see how that's possible, or what you actually used to do.

In any case, if you do actually have the type of GTX 660 that I showed in my picture, then you certainly CAN run BOTH the TV and your PC monitor simultaneously, doing nothing extra or special when you want to do that. Your system will simply support the TWO display devices simultaneously, as part of a "double-wide" Windows desktop. Both of these display devices can therefore be used as output from Windows programs.

However your mysterious description of what you used to do before bringing the computer into the shop for repair still concerns and confuses me, since maybe I don't fully understand what "watch TV" actually means to you.

I don't know what that cable on the right could be. It's not part of the graphics card set of connectors, at least not according to my picture. Maybe it's for external power, instead of being fed the additional power it needs internally with a 75W PCIe cable from your power supply. I don't know. You're not showing the entire card and you haven't provided the manufacturer of that graphics card.

If you could take one more picture showing the entire WIDTH of that card, so that all connectors could be seen, that would be most useful. It's entirely possible that the picture I posted is not exactly your GTX 660, but hopefully since this latest picture does show two DVI connectors it does strongly suggest your card is truly double-wide (i.e. takes up two slots) and therefore probably will have all the connectors I've described... HDMI and DisplayPort along with those two DVI connectors shown in your latest picture.

Just remember, this will allow you to run BOTH the TV and your PC monitor simultaneously, which is what I have assumed you're really wanting to do. There will be no need to enable or disable anything in Device Manager when you want to "watch TV", whatever that means.

But it's possible this new TWO DISPLAY configuration (once you get the proper cable) will give you new flexibility or possibilities, so be prepared for a likely need to conceptually reconfigure your mind to how you do whatever it is you want to accomplish. Again, you'll likely need to use both nVidia Control Panel as well as Windows Desktop -> Properties (from right-click on desktop) to get the TWO DISPLAY configuration set to your liking.

If the On-board graphics (Chip or On-die) are disabled in the BIOS, I believe they would not show at all within the Device manager in windows.

As I mentioned earlier after looking in the User Manual for the motherboard, there didn't appear to be any option to enable or disable onboard graphics as there commonly is, for example, in Lenovo Thinkpad laptops.

This is a PC desktop motherboard, and it simply allows specification of which ONE OF THREE possible locations for graphics hardware should be looked at first. And the PCIe-x16 slot is the typical one to be used, as that's where today's graphics cards go. And that's also what this machine has in it... an nVidia GTX 660 from some still unknown manufacturer, but nevertheless a GTX 660 obviously with two DVI connectors and almost certainly also with an HDMI and DisplayPort connector.

I don't know what OP had before, or how "watching TV" was accomplished by "disabling and enabling something in Device Manager" when there obviously is no Intel Graphics shown in Display Adapter right now. So there are still unanswered questions about the before situation.

But right now, that GTX 660 used properly and with TWO CABLES going to the monitor and the TV is the clear solution to the assumed objective of allowing BOTH DISPLAY DEVICES TO BE USED SIMULTANEOUSLY and without any fooling around in Device Manager to do that.

The TV is simply connected with an inexpensive standard cable that has HDMI at the TV end. The other end can either be HDMI or DisplayPort. HDMI-to-HDMI is obviously a universally common cable, and DisplayPort-to-HDMI is an inexpensive optional order (around $8USD). Either cable supports both audio and video, so the TV's speakers could be used if that's what was wanted. Alternatively audio from the PC to external speakers or sound system could also work.

The monitor is simply connected using a variety of optional cables, if only we knew what that monitor was and therefore what its connector options were, and also whether or not the speakers in the monitor are to be used or again whether external speakers are being used. For video-only, either DVI, HDMI or DisplayPort connector at the PC end of the cable would work. For audio+video either HDMi or DisplayPort connector at the PC end should be used (trying to provide sound via DVI is totally unnecessary and expensive, when a simple HDMI or DisplayPort cable is the obvious solution). The monitor end of the cable can also vary, depending on the monitor and depending on whether audio from the monitor's speakers is to be used. But both HDMi and DisplayPort at the monitor end of the cable would provide both audio and video, or just video.

Only caveat is that a DisplayPort connector on the monitor CAN ONLY BE FED FROM DISPLAYPORT CONNECTOR ON THE GTX 660. You can't feed DisplayPort on the display device from HDMI on the graphics card using a standard inexpensive 2-ended "passive cable" (although it is technically possible with an expensive "active adapter").


I think OP has enough info to make progress here. Once the needed second cable is obtained, I'm sure this thread will continue on with some more questions and answers.

Im not actually sure what part do u want me to take picture from.And 'watching tv', i only used hdmi earlier to watch movies i downloaded on my pc,therefore i didnt even need both pictures(on tv and on monitor). I dont even need it now coz all i want is to watch movies on tv for better picture.Im positive that i watched it before with hdmi end on both plugs(pc and tv) but im not exactly sure to be honest even what monitor i had,because i have 2 monitors in my house but im pretty sure i used this one as well when i was able to watch it.I dont know what to tell you about intel,thats how it happened,i would just enable intel or disable nvidia and picture would went from my monitor to tv and after that i would just go other way around to switch it.

Yea so I just took dvi cable from my other monitor from other pc and i disconnected the hdmi cable connecting my monitor and pc and put the dvi( there is dvi and hdmi plug on my monitor) and connected the other end in my pc so i had that hdmi plug on pc available and connected my hdmi there,set up a few settings in display and voila,its working,both simultaneously.Thank you @dsperber for all your help as well as everyone else for helping me with this.I guess tomorrow i can buy a cable with both dvi ends as well as one with dvi and hdmi end,it would make no difference
