Welcome to the Community. To ensure that the display options appear correctly, connect the TV to the computer before you enable the display settings.
Click Start-Control Panel-Apperance and Personalization, Under personalization click on Adjust Screen Resolution. The Display Properties window will appear. Click Advanced, click the tab for your video card, that was shipped with your system. In the display devices section, select the appropriate option for using either a single display or multiple displays, ensuring that the display settings are correct for your selection.
One more thing to check--make sure you select the HDMI input on the TV. It is not a monitor and cannot sense what's connected. You must select HDMI 1 or Hdmi 2 or whatever hdmi connection you have. TV remotes have an Input button you use. My Samsung input button says "source" on the remote. Cycle through all of them
To DELL Royan S : I've follow your advises but I didn't saw any option to change to use multiple displays... I've only one choice: "Laptop monitor". And for precision No HDMI dispays are detected but there's like a virtual monitor... I explain : the First time I've connected my TV to my computer a message appeared "no monitor detected, maybe it connected with a VGA cable. YES or NO " and since this message, everytime I've an other display in Screen resolution, even when no displays are connected !
To Mary G : My TV is a Toshiba and my Monitor is a Samsung. I've already check the correct channel. In my TV there's just one HDMI port and the channel is named "HDMI" but nothing on the screen when I connect my PC with the TV.
Ok it's not a monitor but it still doesn't work with my Samsung Monitor.
So I think the problem is the PC...
(I've read that the XPS 17 have an HDMI 1.4 port ... and I don't know if my TV manage HDMI 1.4...)
My system appears to recognize it has been connected to an external monitor (when using HDMI output) but does not send out a signal. I have tried reducing my screen resolution down through all available sizes.
Also tried connecting laptop to a projector using HDMI (output) to VGA (input), but get message saying "no signal detected". If I use this same lead with an external monitor, I am able to see the attached monitor, but I still get no image displayed.
No one at Dell has been able to sort this out yet. An engineer came out and changed the mother board and daughter board. Dell finally sent me out a replacement machine.... but I get the same problems.
I am having this exact same problem. I've used this feature on my old XPS 17 and it works fine. I know its not a user error. Something is wrong with the HDMI output. Can Dell please help with this???
I have had simular problem with my xps17 l702x, using HDMI to samsung lcd HDtv, i can get my desktop to show and work on tv, but as soon as i play a dvd\blu-ray the tv goes blank and the laptop freezes the films, using the laptop on its own not connected to tv the films play fine.......so dell what the hecks going on??
One work-around is to use the mini video port (small port next to the HDMI). I've just bought a mini video to VGA lead (Mac), plugged it in and it works fine.
This doesn't solve the dodgy HDMI port though. Still unable ot get an image out of there. I think this is a driver issue, because when Iconnect a 2nd monitor the laptop picks up the model type - but fails to output any image. I can select the external monitor, and switch modes (single, dual, clone, projector), but no signal gets sent through..... very odd!
Had a 5min chat with Dell tech, they phoned me,problem sorted! Apparently if you select projector only and disable the laptop screen,
Fn/F1 on mine, it will then play DVD\Bluray correctly through th tv, i have just tried this and yeah it does work fine, try it for other issues like games, i suspect it to will work.
Jagarode, im assuming that when you connect the HDMI to your laptop, it is switched off, if not try doing that first, then booting, given the age of your laptop i would imagine it has the latest BIO version and various drivers. Upon booting you should see the window screen and stuff on tv,for DVD\BLURAY play press Fn|F1 select projector only put in film and play,if you have no image on-during or after boot id be looking at a hardware fault in which case hassle Dell lots and lots.
Thought I'd share a quick experience on my new L702X HDMI port connection with my Sony Bravia KDL 40EX423.
Connected PC HDMI port with Sony as Dell & Sony instructed and noted that once I selected the proper screen (PC prompt ie screen 2) the TV responded yet video/sound input pulsed on TV as if signal was being interrupted. Well, being lucky and having 2 HDMI cables I swaped cables and "voila" problem solved. No issues what so ever with video, adjusting screen, watching Blue-Ray discs etc. Put #1 cable back in place and went back to having a interrupted input.
This is a long way of saying can it be the HDMI cable and why do two cable made by two manufacturers respond differently.
Are there subtle differences/uses in labled HDMI cables?
I had the same problem with My TV not recognizing my HDMI port sometimes, but I finally was able to fix this problem. (I wish I had discovered this earlier before I spent an extra $140 to get a TV that would work with my XPS 17 until the problem showed up with that one too :( ) I think it has something to do with Intel and Nvidia not always recognizing the HDMI port. I followed this process to fix it:
1. Go to Device Manager (You can also do this by right-clicking on Computer and clicking on manage)
2. Go to display adapters and expand the slots until you see the Nvidia adapter
3. Right click on the Nvidia adapter and enable it.
4. You're computer should recognize the tv connected to your HDMI port
5. If your computer doesn't recognize this fix right away proceed to steps 6-10:
6. Right click on your desktop
7. Click screen resolution
8. Click detect
9. You computer should then recognize your TV for your to extend, duplicate, and do whatever you need through HDMI.

Hi Jagarode,
Welcome to the Community. To ensure that the display options appear correctly, connect the TV to the computer before you enable the display settings.
Click Start-Control Panel-Apperance and Personalization, Under personalization click on Adjust Screen Resolution. The Display Properties window will appear. Click Advanced, click the tab for your video card, that was shipped with your system. In the display devices section, select the appropriate option for using either a single display or multiple displays, ensuring that the display settings are correct for your selection.
The hot key to move from TV to laptop is Fn+F8.
Hope this helps
Thank you

I'm having the same problems with the xps L702x
My system appears to recognize it has been connected to an external monitor (when using HDMI output) but does not send out a signal. I have tried reducing my screen resolution down through all available sizes.
Also tried connecting laptop to a projector using HDMI (output) to VGA (input), but get message saying "no signal detected". If I use this same lead with an external monitor, I am able to see the attached monitor, but I still get no image displayed.
No one at Dell has been able to sort this out yet. An engineer came out and changed the mother board and daughter board. Dell finally sent me out a replacement machine.... but I get the same problems.
Anyone else get this problem??

@Volsh : I tried what you said but it doesn't work for me...
Maybe uptade the BIOS can resolve the problem... but update it can be dangerous no ?
