Yoga 920 usb-c to hdmi adapter gives washed out blacks on external display

Q: Yoga 920 usb-c to hdmi adapter gives washed out blacks on external display

I am using a usb-c to hdmi adapter to output to a TV but the black levels look washed out. I had no issues with the same TV and a previous laptop that had a dedicated hdmi port. In the intel graphics settings usually there is a "quantization range" setting to change color space between RGB Limited and RGB Full if the intel graphics is driving the hdmi port. However, in this case, there is no hdmi port but instead a usb-c to hdmi adapter, thus the quantization range setting is missing. I've had the same issue before on a previous laptop with usb-c. I've tried installing thel atest drivers, including the non-validated ones from the intel website, but none give me the quantization range setting.

I purchased an external monitor on Friday.  It worked on Friday and Saturday. Sunday when I booted up, the external monitor no longer worked. The history appears to show an automatic update occurred overnight.  I was running Windows 8.1.  I upgraded to 10.  I have uninstalled and reinstalled the intel video driver, I reinstalled the chipset driver.  I have trimmed the micro HDMI cord as suggested in one of the posts.  I have seen enough posts on the various boards to know my issue does not seem to be an isolated case... but I haven't been able to find an explanation of the cause or a reliable solution.  Any help is appreciated.

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 have 2 ordinary external monitors attached to my new yoga 910, and both the monitors have  fonts have a washed out look, sort of like 1/2 their pixels are missing. This only happens in Windows applications such as Visual studio and MS Word menus, not in web browsers or other applications.  One monitor is via an hdmi cable to the Type C connector, the second is via an external graphics card and a hub to the USB drive. Both monitors exhibit the same issue. Does anyone else have this? It worked OK under my previous laptop. The Yoga screen is awesome, so thats not the issue, just the external montors when using some windows applications.

I have a new XPS 15 9550 that I really like and it has a fantastic display. When I connect it to an external Dell monitor with the WD15 the display image is very washed out. I've updated my BIOS and all drivers to the most current version. It makes the use of the external monitor difficult at best. What's interesting is that when I reboot the laptop connected to the Thunderbolt connector the initial external monitor image is fine and then after a second or two flickers and then changes to a washed out display. I've found that if I keep the laptop open so it's display is up, at times the external monitor's display is OK and not washed out. The WD15 is connected to the Dell wide screen monitor with a VGA connector.

I used this monitor with a Dell Latitude E6420 with no issues at all for years. It still works perfectly with the Latitude. There seems to be an issue with this WD15 or the Thunderbolt connector.
Please investigate this issue and find a solution. It's very frustrating.

As you mention that you have video problems following a Windows Update push of a new driver, and that the problems are resolved by reinstalling the Lenovo-provided driver, you may wish to consider turning off WU's ability to update hardware drivers. This will necessitate that you manage all hardware drivers yourself, though.

Hello, I would love to ask for some help!
I've recently purchased the newer Dell XPS 13 9360 Non-touch (not the 2 in 1) and am having some trouble with using an external monitor. The screen (on the external monitor) keeps on flickering and has a very unstable connection. 
I've searched and found that apparently lowering the power output of the WIFI network adapter can fix this problem. 
The problem is that the current XPS's wifi adapter doesn't allow the power output to be changed. The previous fixes were geared towards intel wifi adapters.
The general power settings for the computers doesn't show wifi card power controls.

I have updated all the drivers for the computer including the wireless adapter. Still the options doesn't change.

Has anyone found a way to get a stable external monitor to work with the Killer Wireless Adapter cards?
Any help would be greatly appreciated!

I have 2 TVs currently serving as my screens. I've lately been helping family and friends fix small issues on their computers. I've come across a few PCs that have only a VGA Display Port, while both of my screens only have HDMI ports.
I asked someone at a local parts store, if a wire that is VGA male one side and HDMI male the other, would do the job. He told me in long detail why that would never work, that I needed a signal converter to change the display signal.
Basically he said when adapting a VGA screen to a HDMI port was possible, and the reverse (HDMI screen to VGA port in pc) is not.

My question is, if I bought the cord linked below, would I have to do anything else other than just plugging it in? Or do I indeed need this converter I was told about?

Thanks in advance

You will need a signal converter of some type. A simple wire cable with different connectors on each end will not work. A VGA output has three analog video signals. An HDMI input expects all digital signals.

Hi, I hope someone can help. I bought 2 HDMI cables for my PC and my wifes PC but on fitting them both pictures now have a washed-out quality and the resolution looks blurry. Both Graphics cards can support HD (GTS250 and ATI 4890HD) and both monitors are HD compatible. We have the latest drivers for both cards and monitors. Changing the colour & video settings don't make much improvement. Cards utilities and windows confirm the res is still 1920*1080. I've also 'lost' about 20cms in width and length around the border of my screen. When I move back to D-sub I get the full screen again. My wife has moved back to her DVI cable until we can get this sorted.

Browsing on the net for 'washed-out HDMI' shows that others suffer from the same issue but there doesn't seem to be a definitive answer. I wanted HDMI for the digital sound/1-cable solution but the picture quality loss is too hard to bear so far. I'd be gratefull of any help or ideas.

Thanks.

My XPS13 9350 was one of the first with USB-C port (Thunderbolt 3) only and no DisplayPort, supplied in early 2016. It has caused a lot of headaches. As I tried to connect my external Dell monitor using  a USB-C to HDMI adapter from Dell (part no: 47KD7) there was no external display at all. Dell Support advised me to update BIOS. But it led to a complete freeze of my laptop and Dell replaced the motherboard. (It was a real nuisance as I use my laptop for work!!)
With the new motherboard,  the laptop/USB-C adapter/external monitor worked fine for 15 months. Until one day, out of the blue, the external screen started flickering with an image that was all distorted (cut in the middle). The laptop screen was fine. After a few weeks of flickering, there is no signal at all to the external screen. Moreover, as I connect the adapter in USB-C port the resolution on my laptop screen changes.
I know there have been a lot of issues with USB-C connector on XPS 13 and 15.  I have reduced wifi-power to 50%  but it has had no positive effect (several persons have said on this forum that it helped the video output). 
I am grateful to learn if anybody with similar problems found a solution. Cheers

My ThinkPad laptop computer does not have an HDMI port, so in order to connect my computer to my HDTV I use an adapter plug which accepts an HDMI cable male plug (from my TV) and then plugs into my a/v display port. I've gone thru a few of these adapters because for some reason they tend to develop connection problems, like loss of the audio portion, or whatever. The current plug is shorter than my previous ones and less likely to get bent, but all of a sudden I've lost the audio transfer again and when I went to unplug and replug the adapter to make sure the connection was secure I found it was very hot. I don't recall it ever being that hot before....some heat, yes, but this was very hot. Not a good sigh....eh?

When this same audio loss has occurred in the past, unplugging and replugging the adapter has worked, turning the TV off and back on again has solved the problem on some occasions, other times it took restarting the computer. And then on some occasions the loss of TV audio was due to my receiver input setting getting accidently altered (I run my TV audio thru my receiver and into a Dolby surround sound speaker system). None of these remedies have worked this time however.

In this case I'm more concerned about the overheating issue than my loss of audio transfer. Can anyone with good technical knowledge comment on this high heat matter....should I trash this plug immediately?....can damage be done here with an overheating plug, or is some heat to... Read more

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

I just purchased an adapter plug that allows me to connect my Lenovo/IBM thinkpad (T420) to my HDTV by plugging the HDMI cord into my TV and the other end to this adapter plug which converts the HDMI cable into a male plug which fits into my display port (there is no HDMI port on this model computer). It worked, but now I can't remove the adapter plug...it's stuck in the laptop display port. I do not know if the problem is caused by the male adapter plug or the female jack in the computer, but they're locked together now.

I have previously read review comments (on these HDMI/display port adapter plugs) mentioning this jamming happening on more than a couple occasions, but I don't recall any resolutions being mentioned except to break off (and destroy) the plug and possibly damage the display port as well. I called Lenovo tech support but they said I'd have to mail the computer to them to get it fixed. I'd prefer avoiding that if possible even though my warranty is still in effect and it would be of no cost to me.....just time lost without a computer.

I'd greatly appreciate hearing from anyone who may be aware of how to resolve this problem (and also how to avoid it happening again) without doing damage to either the plug or especially the computer display port.

Thanks for your consideration in any case....

I upgraded to Windows 10 last week and everything was smooth.  Today when rebooting my system, the unit no longer can see my external display.  I have tried multiple other displays and none seem to work.  I have the latest video drivers for Win10 from the support site installed but it still doesn't work.  Any thoughts?

A:Yoga 2 Pro + Windows 10 = External Monitor not working via micro HDMI

I experienced the same - and also inconsistently that the system is going sluggish/lagging heavily. To fix problem with HDMI downgrade to drivers for Win8.1 - it works but hopefully Lenovo will fix this issue with Win10 drivers!? Overall upgrading to Win10 has been a bad experience (regarding the lagging of the system which usually occurs after 20-30 min after logging on). I've tried removing all third-party startup programs (including Lenovos) - but to no help. The frustration is increasing - any tips will be appreciated :-)

How do I get two external monitors to work with my new Yoga 730 15 inch? I have a USB-C to Hdmi but I cannot use it and the HDMI port because all three screens will not show up, only two. Only two monitors will show at one time. What can I do to get these to work?  Is there a docking station I can purchase? I have the Lenovo part GX90M44577 that is the USB-C to HDMI port.

 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
