TV screen is blank when connected to desktop via HDMI, until I also plug in a second monitor. How to get first screen to work alone?
I recently purchased a Samsung Smart TV, and have been using it as my computer monitor for a few days. I have it plugged into my computer via HDMI cable. The problem is, when I start my computer up, the TV screen is black, even though the TV says there is a connection. The screen stays black until I plug a second monitor into my computer via DVI cable. The second monitor will then be black, but my TV then works. I have my computer settings set to "PC screen only" and have my TV set as Screen 1. Does anybody know how to get the TV screen to work right away, without the hassle of the second screen? Please help!
(P.S. After I've plugged both screens in and got the TV screen to work, I can unplug the second screen and nothing changes. It's only on start up that I need to plug in the second monitor to get the first to work.)
My computer is an Acer Aspire TC-605 desktop tower running on Windows 8.1. My TV is a Samsung 4k Smart LED TV, model number UE43KU6000. I have the "project" settings (what screen an image should appear on) set to "PC screen only", which means only "Screen 1" will display, and I have set my TV to Screen 1 in monitor settings. My only graphics card is a NVIDIA Geforce GTX 745 fully updated. I'm using an Intel core i7 4770. I have the TV connected via HDMI cable, into the only HDMI port I have.

** please bear in mind a TV is NOT a monitor a monitor is expected to ANSWER when a pc says to it What are you? and what native resolution are you? ** thus therein lies one of your problems. it is because your tv is effectively a 2nd monitor that is a Projector and your driver has been told its a 2nd monitor or assumes it is because it doesnt answer. or you havnt explained properly what GPU's you have. typically a desktop will have an Intel GPU which should have an HDMI socket on the mainboard. Your BIOS will treat THAT HDMI socket as your 1st display that is your 1st GPU(windows has had the two gpu thingy for 20 years or so). if you are talking about an HDMI socket on an ADD-IN GPU, then you might NOT have set the 2nd GPU as the BIOS default(1st GPU ie INIT:Pci-e) this would push the mainboard HDMI into LAST place. It is up to the add-in GPU maker as to how their sockets work on their cards and HDMI are now usually 2nd after Thunderbolt or DisplayPort connectors, so if it is an add-in card and it has a DP or TB port you may be scuppered. seek help ffrom the add-in card maker.

Are they plugging into separate video cards? The TV needs to be plugged into the primary video card in the BIOS settings. Which is normally the first PCI-e card (PEG/Dedicated depending on BIOS wording) if you have dedicated cards installed. Although the setting could be for integrated graphics (INT/Internal).

it sounds to me as if the graphics software can't get a response from the tv on startup and thus thinks there is no monitor attached.
please reread the Samsung instructions for how to set up the tv as a stand alone monitor. you may have to read the FAQs or help answers on the Samsung website for this -- I didn't see it in my new Samsung's setup instructions.
