Haswell integrated graphics problem

[Alec0905]

Hey everyone,

I recently built a new computer and am having problems with getting the Haswell integrated graphics to work correctly (or at least as expected). I get severe ghosting using VGA, and HDMI is very fuzzy (it's overcasted by default, which seems weird for a standard 1080p resolution). I've tried it on two different monitors, so I know the monitor isn't the problem. I have a i5-4670k haswell processor and am using the AsRock z87 Exreme4 for the motherboard.

I've also tried uninstalling/reinstalling the graphics driver. I've used both the Intel HD4600 driver and the standard VGA driver at 1920x1080, and both show the same blurriness/overcast problem.

I've built a computer before with no problems, and I'm all out of guesses as to what my problem could be. It seems weird that I'd get picture, just in a blurry and unclear way. Any advice or help would be much appreciate!

Does it do this within the Bios?

 

[Alec0905]

Ah, I didn't think about looking at that. Anyways, I looked, and yes it has that problem in the BIOS as well. Does that pretty much guarantee I have a faulty CPU or MoBo? Everything else seems to be working fine, so it'd be really unfortunate to have to return this for what seems like should be an easy thing to fix.

Oops, accidentally double posted. Ignore this.

If it is doing it in the bios that probably means a hardware fault of some sort. I suspect the motherboard. Of course, check for interference first. Cables are all plugged in ok etc. Even try a different power outlet. But I suspect it's a hardware problem unfortunately.

Does sound like a mobo issue.

If its in the BIOS, I'm calling hardware issue. Contact the motherboard manufacturer and ask for a refund/replacement.

it's some interference in mobo

although these things are really rare I seen only one computer which ever did this

till certain point it is doable and you can try to get used to it unless it doesn't cause you headaches or eye strain or bother you very extensively

Is the monitor being driven at native res.? I don't see how HDMI could be "blurry and overcast", unless the monitor was being driven at a non-native res. Overscan?

Possibly the HDMI is being adapted to another signal type?

OP, is this an HDMI to HDMI connection using ONE cable, or are there any extenders / converters / anything in between involved?

Also is anything overclocked?

Severe ghosting with VGA, and fuzziness with HDMI? I would say the CPU is faulty.

EDIT>> Is the installed BIOS the latest?

Wow, I'm shocked by all the helpful responses already. You guys rock . Anyways, I'll try to answer all the questions so I can narrow down what's going on here.

• I originally overclocked the graphics card using the MoBo's pre-set options (I set it to the least amount of overclocking of the 3), but I changed it to stock after the problem started happening, to no avail. The CPU is also overclocked to 4.0GHZ, which I have not changed yet. I didn't think that the CPU OC would be a problem, but I could give it a shot.
• The monitor is being driven by a straight HDMI to HDMI cable (or VGA to VGA), with no intermediate adapters. I actually stole the HDMI adapter from an apple TV that was working fine, so I'm fairly certain the cable isn't the problem.
• Intel's integrated graphics program seems to recognize the monitors OK, but like I said, I have to shrink the screen on HDMI to get it to not overscan, which seems indicative of a problem. On VGA the screen "fits" correctly, but there is definitely major ghosting. It's probably also worth noting I originally had this hooked up to a 2560x1440 monitor, where it ran at 1920x1080 (non-native obviously) through DVI-D and HDMI. The setup was fuzzy with those as well.
• I'll check the MoBo bios when I get home (I'm at work), although I'd guess I don't have the latest version. It looks like they updated the BIOS because of a UEFI freezing problem, which has not happened to me.

One more thing I found interesting: I took a print screen of the ghosting to post a picture of it on here, and in doing so, I realized that the ghosting doesn't happen when you look at it from another computer. Using my laptop on the same monitor, the ghosting wasn't there. That's something I can't quite wrap my head around, and might be a big indicator as to what the problem really is. Any ideas on how that could happen? Maybe like Sheep and Stinky said, there's interference somewhere leading up to the display?

Thanks again guys! I can't wait to have this thing actually functioning like I expected.

So it wasn't acting like this when you got it, but it happened after you had been overclocking the video for some time? Sounds like you fried something.

 

[Sheep221]

The IGP in Intels is not really intended for overclocking, what you wanted to do with it?

Hey guys, I took the computer over to my parents this weekend, made sure all the wires were plugged in completely, and it now works great on a 25" monitor. I'm not sure if one of the MoBo plugins was slightly loose or what, but for now all seems good. And as long as the computer itself works fine, I'm happy. I can deal with external issues involving adapters or monitors. Consider this solved, and thanks again for all the help!

I'm always happy to see someone fix their own problems. Because you figured the problem out by yourself you'll never forget the next it could happen. Congrats!
