HDMI No Signal instead of Standby on Monitor

[Poppa_Meth]

I'm seeing where this is a somewhat common issue, but not a lot of info on what causes it or how to fix it. I just finished upgrading an older computer with a GTX 1050 Ti and an Asus VS229H-P Monitor. I have the monitor connected via an HDMI cable. Now whenever I leave it long enough for the monitor to go into standby it instead goes to a blue screen and says HDMI No Signal. At this point it isn't possible to wake the monitory by moving the mouse or pressing a key. I have to press the source button on the monitor and it'll come back on with no issue. While I was waiting on the card to come in, I had this monitor hooked up via HDMI to the onboard graphics (Radeon 4200 I believe) and I don't recall having this issue at all. So I'm assuming this may be a handshake issue with HDMI between the monitor and the card. I haven't found any drivers for this specific monitor, but I did find one for a plain VS229 which installed and seems to work fine, but did not resolve the issue. I'm going to try a DVI connection next to see if the issue is still present. Thankfully the monitor and card both have a DVI port. I'm just curious if anyone has input on fixing the HDMI issue because a lot of newer monitors are dropping DVI connections so I'm seeing this as an issue in the future.

Have you tried changing the power plan options for the monitor (Set "Turn off the display" to "Never") plus changing the Windows screen saver setting to "None"?

Yep, seen it several times, seems to be more monitor-related than anything else. Changing connector always solves it, Cable itself may be part of the issue, I'm pretty sure I used a DVI-HDMI adapter or cable and that solved the issue, but don't recall if it was reversible or needed the adapter on a specific side of the connection.

If turning off the power save setting, and also if PC is on for 24 hours or more, I would use a screen saver.

[Poppa_Meth]

I have it set to screensaver after 5 minutes and turn off display after 15 minutes. I'm sure that if I set it up the to never turn it off the issue would be gone, but I want it to go into standby. Been working fine that way until I set up the new card. I checked for power save feature on power plan PCI-E settings and on the monitor. Both were already off. There is also nothing in this very limited BIOS to turn off on-board graphics. I did notice that even when turning on the computer from a cold start I have to turn on the tower and then the monitor. If I turn on the monitor first then it gets no signal either. Right now I'm trying the DVI connection to see if the issue persists. I really hope not. This is a friend's computer I'm setting up for him and I don't need phone calls all the time about why the monitor is not on. So far, on startup the DVI is automatically detected, so that's a good sign. Most of my HDMI cables are the same brand and make, but I may have a basic Amazon cable somewhere if I can track it down.

[Poppa_Meth]

Well DVI says no signal as well, but moving the mouse brings the screen back up. So it's working via DVI with no issue. I'll try to test another HDMI cable and I think my other ASUS monitor has HDMI as well that I could test the card against. The more I researched this, the more I found that people are having this issue with both HDMI and Displayport. That is scary considering DVI is suppose to be phased out. I've already seen too many panels with no DVI port for my liking.

Found my Amazon Basics HDMI cable. I can now power up the monitor before the computer and get signal fine. Monitor also resumes from standby fine with this cable. So the "high quality" cables I had bought are evidently junk. Proves you can't always trust reviews. Thanks for the input.

[JVRaines]

Would you mind sharing the make and model of the HDMI cable that didn't work?

[Poppa_Meth]

Sure. They are Twisted Veins. Amazon link is below. Bought these because they have a huge amount of 5 star reviews. Reading into some of the bad reviews reveals some information about problems with signal transmission. I guess for most applications these issues aren't a problem, but when you hit something specific they come into play.

Well, when the top review screams "Incredible Product!" over something as mundane as an A/V cable, you have to be suspicious. Amazon reviews have been gamed for a long time now. But I do see one which seems reliable; it's from a Chad Simmons. Do you know him, by any chance?

[Poppa_Meth]

I didn't see that one at time of purchase. I think I was on mobile. The more I read the reviews the more contrived they seem to be. I'm betting this is one of those companies that contacts buyers after the sale to solicit a favorable review in return for an Amazon credit. I'll have to check my spam folder to see if I got such an invitation.

As for that Chad guy, don't know him. Sounds like some kind of lowlife loser. Who names a kid Chad anyway? Some guy that has a Bond fetish and broken down Lotus in his driveway I bet....

A little update. I was contacted by the seller yesterday letting me know that they are shipping me replacement cables free of charge and crediting the other ones I had already bought. They seem to think it was just a defective cable and not a design flaw. I must have gotten 6 defective cables all at once. What an odd occurrence. I'll test the new ones to see, but I'm not holding my breath.

[Poppa_Meth]

I received those replacement cables last night. I've now tested all six new ones on three different computers with different operating systems and guess what? Same problem. They tried very hard to appease, but it might have been advisable to actually check the product for the described design flaw before sending out the same problem again.

It's odd that you've had luck with a single cable, but not with any of the newer ones. HDMI cables tend to work or not work. Very little in between.

When you tested with the old cable, was the monitor still running at the same resolution? I ask because Nvidia seem to distinguish between HDMI and DVI according to the resolution and refresh rate, not the type of connector. For example the old Nvidia card in the second PC here is connected to the TV via a DVI to HDMI cable. The TV has no DVI input and the card has no HDMI output. When I check the displays in the Nvidia control panel though, it shows the TV is connected via HDMI.

I mostly use this PC connected to the TV via VGA (same Nvidia card), and the TV works like a monitor that way. When the computer goes into standby mode, so does the TV. I don't generally don't leave the TV on after using the second PC connected via DVI... I turn the TV off manually.... but if I remember correctly the TV displays "no signal" when the PC's snoozing, however it does detect it again when the PC wakes up.

There's also an LCD monitor connected to that PC. I've barely used it so I can't remember how it behaves. I'll test it later and report back, but I think it behaves as it should. It has no DVI input so once again I'm using a DVI to HDMI cable. Maybe you should try one of those?

If you need audio down the cable you can do it while using the DVI out. You need a DVI to HDMI adaptor or cable, and for older Nvidia cards with no internal audio codec, you need to connect your soundcard to the video card with a S/PDIF cable. Most Nvidia cards have a S/PDIF connector. http://nvidia.custhelp.com/app/answers/detail/a_id/2593

I've mentioned all that in case the DVI output behaves differently than HDMI. I don't know if it would and I can't test it because my card only has DVI out, but I'll check what the TV and monitor do when connected that way (probably tomorrow) and report back if I discover anything new.

It definitely wasn't an issue with the monitor or the card. I tested these same cables at work connecting a laptop to a monitor via HDMI with the same results. Everything works perfectly fine except the monitor will not wake from standby without pushing the source button. Swapped that to an HDMI cable I bought at Staples and the monitor works fine again. Don't know exactly what is wrong with these cables. They may work fine for regular AV connections, but not with a computer monitor. DVI connection on the first monitor had no issues and the resolution was unchanged in the NVVIDIA control panel.
