My Thinkpad Yoga 15 has a problem, which may or may not be related to the BIOS update recently performed. When booting, the bootup screen only appears on an external monitor via the HDMI output. When performing the hardware tests in the BIOS, tests are done on the HDMI-connected display, the internal display does not seem to be recognized. I verified this using both Linux and Windows. It does not seem to be a hardware failure; I have been able to get the display on the internal LCD a few times, by powering down the laptop, holding the power button for about 20 seconds, then powering back on while pressing F1. The laptop will then function for a while, but loses its display after coming out of sleep. Needless to say, this is unworkable. Does anyone have any tips on how this could be fixed in a more permanent fashion or any indication to cause? BIOS does not allow me to turn off NVIDIA, or its opposite, to enable it exclusively. I also tried different drivers, from both Lenovo as well as NVIDIA and Intel, but to no avail. Any pointers appreciated.

I was moving our Dell Studio 17 laptop and the screen went blank. I thought it did a power save or something. But I could not get it redisplay anything..no flickers, nothing.

I rebooted, nothing.

I opened up the back and reseated the ram and verified the hard drives were secure. I vacuumed out any dust. No difference.

So I tried using the HDMI with our TV and it displays just fine. I try to toggle the screen (function F8 on my laptop) and it makes no difference. HDMI is always shown.

In the past when we use the HDMI to display netflix movies on our TV, I hookup the HDMI and the laptop automatically switches to the HDMI display and turns off the laptop display. When I unplug the HDMI, it wouldnt turn the laptop screen back on. I would have to reboot with the HDMI disconnected for the display to come back.

Now rebooting doesnt not bring the screen back.

Anything else to try? are there settings somewhere forcing the laptop to not send info to its own screen? BIOS?

This laptop has an ATI card and uses the latest drivers. It does have the Catalyst control center where it detects the displays. It seems the 'unknown' laptop screen and TV (when HDMI is connected, the only way I can see the screen at this time)..but it calls them duplicates and calls both of them #1 display.

Thanks for the help

When viewing the Dell Optiplex 9030 specifications, it states that the device can be used as an external display for other devices, via its HDMI input.
I have followed the instructions given in the link below to link-up a MacBook Air as a video input, using HDMI. One user in the thread below says they have successfully done this, although it is not working on my machine. 

When I switch the display from "PC" to "HDMI" using the OSD (On Screen Display) buttons it only shows a black screen, although my MacBook Air detects that it is connected to the Dell Optiplex 9030, and adjusts its settings accordingly. On the Optiplex 9030, the question-mark below where it says "HDMI" on the OSD disappears, but no signal is displayed on the screen. 
Can anyone please explain a workaround to this problem?

Hi daproof,
 
Welcome to the Community Forums.
 
You may need to replace the LCD panel.
 
You can check on the hardware manual (here on page 63) if you have the tools and skills to change it. You can get the LCD OEM part number here to check online or on service parts center to purchase.
 
 
Here is the article guide that can also help.
How to Look Up and Purchase Accessories, Upgrades, and FRU/CRU Replacement Parts
 
At this point, it is likely a failed lcd backlight as image still is visible onscreen when illuminated but you can try to reseat cables first and check areas you can clean but setting expectation for LCD panel replacement.
 
I hope this helps answer your query.
 
Regards

Hi, I just got my Thinkpad P70 4k with Nvidia Quadro M3000M graphics this week, running Windows 10 Pro.I have run into a lot of issues regarding HDMI output - switching to discrete graphics disables the HDMI output and i can no longer change the resolution or scaling (nor does the Nvidia Control Panel show up). In mixed graphics mode the HDMI output works, and i can change the resolution  but after waking from sleep the image only shows on the external (HD display) connected over HDMI.I have to disconnect the HDMI cable to get video on the laptop screen and the reconnect it to get video on both screens.I suspect that the Intel Graphics runs the Laptop Screen in mixed graphics mode, in the Nvidia Control Panel I can only control the external display.    I am running the latest BIOS (2.03) and updated the Nvidia Drivers directly from NVIDIA (10.18.13.6256).  On another note I also had a black screen issue after updating the BIOS to 2.03 (no idea what version came installed) everytime i rebooted and had to disconnect the Bios Battery twice, but that somehow (??) got resolved after taking out a SD card from the Card Reader.

Hello everyone,
I have a problem with my HDMI output. I have a Dell Inspiron 1525, running Vista Home Premium 32bit. I recently discovered that I can hook my laptop to my 60in LG Plasma display via HDMI and do homework large and in charge. Unfortunately, it has stopped working.

Everything worked fine for a few days, I just plugged my cable into the back of the tv, clicked "Connect to Display" in my "Personalize" window from the desktop right-click drop-down menu and everything worked perfectly. I have not adjusted the refresh rate or resolution or any other setting for that matter.

When I came home from school today I repeated all the same steps but now when I plug the cable into the computer, the sound (when you plug into a port aka. dooDEE, I know, I'm nuts, just say it to yourself) keeps going back and forth between plugged in and unplugged (DEEdoo). Repeatedly over and over as if I would keep plugging it in and unplugging it again. (As if there is a problem with a driver)

I have searched all through the device manager for !'s and disabled the HDMI Audio Output Codec then re-enabled, as well as reset my plasma display to default settings. The personalize panel also cycles through "Display Connected" and "No Display Detected" during this time.

Please, if you're a guru, extend some help, if you're gonna ask if the tv is plugged into the wall, don't waste our time. Any help from knowledgable sources will be much appreciated ... Read more

Hi! Please help!

This was working fine before I had to format my computer. I'm about six hours deep in this it's killing me. I'll provide you with any info I can, but I'm far from knowledgeable about this kind of thing.

The problem:
My second display is recognized by my computer, but it receives no signal, showing a blank screen with no sound.

My setup:
Windows 7 64bit. I have a monitor as a main display and a TV connected as an extended display. The monitor is connected via DVI. The TV is connected via HDMI. The TV is a PDP-R04. My graphics card is an AMD Radeon R9 270X using the latest drivers (14.501.1003.0). The cable works tested on other devices with the same TV. The TV works. The source settings on the TV are correct.

Things I've tried:
- rolling back to previous display drivers
- uninstalling display drivers in safe mode and re-updating
- resetting CMOS to defaults
- booting computer with only the TV plugged in
- changing the TV's resolution settings
- crying

Hi All, newbie to this forum. I have a sound disappearing problem.
Yamaha RX-V371 receiver,
Vizio E 321VL TV,
Chromecast,
Win7 Laptop with HDMI output
OK, so I feed the Laptop HDMI to the Yamaha HDMI-1, the Chromecast is plugged into HDMI-2 to the Yamaha and the HDMI output of the Yamaha goes to the VIZIO HDMI-1.

I am a little hard of hearing, so I use the TV sound when watching movies with slightly muffled sound as the crappy TV speakers add just enough harshness to be useful.

It all works individually - sometimes. I looks to me like it depends on what setup was running when the Yamaha is turned off and then the Yamaha seems to decide what is allowed when I turn it back on. It seems like the Yamaha is deciding what sound I need over the HDMI connections when passing it through to the TV HDMI.

Sometimes the sound works on the TV and sometimes it does not. I cannot seem to find a connection or start up sequence that always works. Therefore I am not sure what is causing the issue.

If I disconnect everything then connect just the laptop, OR the just Chromecast then it works just fine. There is something going weird with the combination when all plugged in.

I am lost with this one and I am no novice to hifi, TV or computers. Try as I might I cannot find a repeatable start up sequence to begin finding out what is happening with the sound.

Thoughts and suggestions would be very much appreciated.

Thanks
Harry

 My dad bought an Ideapad 310-15IKB about 15 months ago from Best Buy (USA). That puts it out of warranty, right? I used Lenovo Vantage to check for a display driver update and none was listed. A BIOS update was listed, but that does not seem to apply to this problem and I have not yet done the BIOS update (fix one problem at a time). In recent weeks his external HDMI display had started to flicker/shake A LOT, particularly on his Yahoo home page. I took one look at the shaking and thought "screen resolution problem." The Ideapad 310 "preferred" resolution (the max) is 1366*768. Up until a week ago he used a Dell display that did 1920*1080 and then the next lower resolution of that monitor is 1280*1024. Somehow the Ideapad 310 worked well with that monitor for many months in spite of the seemingly incompatible resolutions. But recently he started getting SUBSTANTIAL screen flicker/"shake" on the Dell monitor. It went on for weeks and then I lent him an HDMI cable and a Samsung HDMI display that does exactly 1366*768 = preferred 310 resolution & preferred Samsung display resolution. His HDMI cable was probably fine, but we changed out the cable, too. The new combo of Ideapad 310 + Samsung monitor still occasionally flickers, but not nearly so much as before. I am currently using his Dell monitor as a 1080p HDTV. It works perfectly. The way he uses the external monitor is:- after bootup the laptop displays on the laptop panel onl... Read more

The title says it all. I'm very frustrated with this problem since I really need to connect my laptop to an external monitor for work. I've read and tried all relative topics in this and intel forums (e. g: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-920-can-t-connect-to-any-external-mon...), have done all steps mentioned (including firmware, bios and windows update, windows reset, ...) but the problem still persists. Apparently, most users that had faced the same problem been able to get it worked after installing "Type C Firmware for Windows 10 (64-bit)" or the BIOS update provided by Lenovo. I installed them successfully but nothing changed. I am sure it is a software issue since there is no sign of any hardware one (all devices are fine as device manager shows and diagnostics app found no problem). It was just working fine until suddenly stopped working (probably after some recent windows update). I would greatly appreciate any help.

so last month I bought an Acer Switch 5 which doesn't have HDMI or VGA ports and was reassured that an USB-C to HDMI adapter would work for me to display presentations on customer/prospect screens when I visit their offices.
So far I have tried 2 different brands of USB-C to HDMI adapter cables and both show a USB not recognised error on the Acer.
So how to fix this?
Is it a brand adapter cable issue?
Is it a USB-C driver issue?
or something else?

I really thought in this day and age of laptop/tablet sophistication problems like this wouldn't occur. Feel like I want to go back to my 4 year old toshiba laptop with a VGA and HDMI port and no issues!

I have a new Inspiron 7567 gaming laptop; it has two graphics cards, the integrated Intel HD 630 and the 'semi-discrete' Nvidia Geforce GTX 1050 ti.
Yesterday, I tried plugging it into my HDTV using an HDMI to HDMI cable. I have done this many times with my previous laptop, a Dell Inspiron n7110, and have had 0 problems. With the 7567, however, the TV just flickers for a moment and says "No signal". The computer reacts in a few different ways when the TV is plugged in:
In the Windows 10 "Display Settings", options appear for multiple displays such as "Extend Display", "Duplicate Display", etc., and with Windows + P I can choose these, however, only one screen is shown (which changes from 1 to 1/2 when HDMI is plugged in) and when I click on "Detect" it says that no other display is detected. Additionally, an extra Monitor (Generic PNP Monitor) appears in Device Manager when the display is plugged in.
In the Intel Graphics Settings control panel, there is no change when the HDMI display is plugged in. There are no multiple-display options, and "Detect" does not detect any other displays.
Finally, in the Nvidia control panel, when there is no external display plugged in, the only section in the left-hand tree menu is "3D Settings". One of the items under it is "Set PhysX Configuration", which shows "Laptop Display" connected to "Intel HD Graphics 630" with a line, inside ... Read more

A T470s on the UltraDock running two Samsung 3840x2160 monitors scaled to 2560x1440 at 29Hz. One monitor uses the docking station's HDMI output, the other uses the DVI output. Nine times out of ten reboots, both monitors come up fine. It's that tenth time that is challenging - Both monitors will comes up normally, but the HDMI one intermittently blinks a partial screen, rectangular image horizontally offset from the actual background image. It flashes two/three times and then disappears. Then a minute later it's back. The size of the partial image varies, the flashing interval varies, but a reboot tends to fix the problem. I've swapped HDMI1 and HDMI2 plugs on the monitors, I've switched the actual monitors, and I've switched the cables. But after ten or so reboots, the image shows up on the HDMI monitor again. It's annoying, but sending the T470s in would take time, and the problem could be at my end - Cable length? Cable routing? I just don't know. Any thoughts out there? (Maybe someday I'll capture that "image" and post it, but so far it's as hard to capture as it is to understand.)

The problem: Latitude E6440 external display blinks when connect via hdmi (see attached video file)
Dell Latitude E6440: Bios A13, Intel(R) HD Graphics 4600,AMD Radeon HD 8690M.

In charging state (while charge level less than 100% ) - no problem, after 100% - again problem
Some test cases:Primarily AC Use: problemCustom mode: 50% start ...90% stop charge (~70% charged level) - problemExpress mode: problemSome correlation from time after ON:~ 1....15 min - often (up 3..5 mins between re-connection HDMI)~ 15.....30 min - rare (up to 10 mins between re-connections)

A:Latitude E6440 external display blinks when connect via hdmi

Hi SI K,
If you haven't already done so can you update the Intel 4600 and AMD8690M first.
If the issue is still there then:
1. Restart the system and tap F2 to enter to the Bios
2. Navigate to 'Virtualization' and choose Disable (uncheck the box)  
3. Also disable VT for Direct Io and Trusted Execution 
4. Return to the main menu in the Bios and select Power Management Option and disable Advanced Battery charge configuration
Once you have done that check to see if the issue is resolved.
If it isn't then open the Intel Graphics Control Panel, go into Advanced Resolution and change the frequency for the LCD from 40Hz to 60Hz
