HP 27" IPS random black flash only with NVIDIA onboard vid fine

[techinthedark]

I bought a new HP 27" IPS display about 2 weeks ago, I have a Zotac Geforce 750ti card. The new monitor doesn't have DVI so I'm suck using HDMI. My zotac only has HDMI mini, so I ordered a 6' HDMI to HDMI mini from monoprice.

Well waiting for the cable I hooked up the HDMI cable that came with the monitor to my onboard video using Intel 2500 and there latest driver. It worked fine, no issues what's so ever even on YCbCr.
Fastforward a week later, I got the cable from monoprice yesterday, uninstalled the Intel driver reinstalled the Zotac card into the PC and used the old driver that worked fine previously. I at first enabled YCbCr 4.4..4 and noticed at completly random the screen would just flash black. I was able to finally able to replicate the problem a few times going to Youtube going full screen and back to normal also other news/entertainment sites with embeded video. But it does it on RGB limited and full as well...Uninstalled and installed the latest drivers from Nvidia same problem

I've reseated the graphics card, I've reseated the cable, and tried switching from HDMI 2 to HDMI 1 on the back of the monitor. I'm not sure if I should try a different cable solution IE: DVI cable to HDMI or just throw this card in the parts box and buy something else, which will be a while don't have the funds right now. But I'm hoping someone else has run into this and chime in with something I missed or a better cable / adapter that I can try.

I would try a different cable if you have one. The 750 ti worked fine on previous monitor sounds like?

Unfortunately this is the only cable I have with mini hdmi. Of course I live in an area with no tech related stores so have to rely on online sources. I'll have to google mini hdmi to hdmi see what other brands out there.

Card Used to work fine on my old monitor via DVI I had a 22" LED LG, but the backlight got flaky. On resume it would strobe and flash for a good 40 seconds to minute.

Could be the HDMI port on the card then maybe? A DVI to HDMI converter isn't too expensive at Monoprice.

If you can get into the bios change the video to PCIe .

I can get into the bios, I have an MSI mobo when you insert a PCIe graphics card it auto disables internal video.

I uninstalled Nvidia drivers, and did a clean install with an old one I found on my HD. 362, I remember that being a fairly stable release. So far knock on wood it's been working with out the black flash for a while now. I'm still thinking of replacing the cable though. No hate on Monoprice but this cable feels pretty cheap even for the 10 bucks with shipping I paid for it. Also wondering if dust could of got in the mini hdmi port on the graphics card since I've had it for a good year or so and it's just been open collecting dust. I just had the PC offline last week dusting it out, never thought to hit the back of the card.

Well it's still doing it :/ Especially on YcBcr constaly flashing if I put it on that mode.

I ordered a DVI to HDMI cable from Amazon, see if that sovles it.

I used to have that problem, with a 26" KDS LCD monitor (1920x1200 + speakers) using HDMI, with a Gigabyte WindForce OC GTX460 1GB card. It turned out to be the HDMI cable. I switched from a generic cable, to a "Firefold" branded one, and then it was fine.

 

[techinthedark]

Well, I think (knock on wood) I fixed it! I bought the DVI to HDMI Amazon Basics, not trying to be cheap here but it had really good reviews. So far no flashes or flickers. Now I have to wonder if the problem was the mini hdmi cable or if the mini hdmi on my graphics card is faulty. I would like to further test that theory but I'm also in the camp if it's not broke don't fix so I'll probally let it go. This card is going to get replaced eventually when I have the funds.

Edit: It also looks a lot better then it did with the mini hdmi cable, same settings and RGB Full. I don't think it's a placebo thing, I mean the over all image quality with the same settings. But if that other cable is bad it would in theory not deliver the correct signal.

Ok never mind it's still doing it I guess it's this card then? Though it seemed fine on the old monitor, but I don't have this problem using internal graphics. W the actual heck, I've trouble shot some anything things in my days but this is got me.

Dug out an old Sapphire 3850 Ultimate from the parts box, last known working so I'm going to give that a go. If monitor flickers again back to the store it goes, don't care if it's working on internal graphics or not.

Also possibly you didn't try the onboard for long enough? Seems like it worked for a bit with the 750 TI and THEN had issues... maybe you didn't use the onboard long enough?

Thanks for the reply, I had it on at least 4 straight up days the first time with onboard was waiting for the cable from monoprice. Not once in those days did it have a problem, then I hooked it for at least another day or 2 waiting for the Amazon cable. It seems like soon as the card is at temp maybe or load it's having the problem since it's fine at boot.

I've had no issues using the new Amazon cable with the old Sapphire card, wich draws even more power and requires the extra pci-e 4 pin power plug to be connected. I have an Antec 550 (rebadged seasonic) PSU.

All signs point to the video card then.. best of luck

Well one final, hopefully, update. I bought an MSI R7 240 from Newegg. I know it's a POS, but for $14 after rebate will make a handy spare when I replace it down the road.

That said 36 hours uptime, no issues what's so ever. Other then the fan being noisy, sounds like an old Pentium 1 fan :/ but it works and no flashing black screen!
