    Is there some reason why you're using an HDMI cable rather than the DVI cable that the monitor comes with?  That might have been the indirect cause of the problem:  while computer monitors can use HDMI, it's primarily for televisions.  DVI is far more likely to be a computer monitor.  That makes a reasonable guess if the video drivers don't recognize the device on the other end.

    It's good that you fixed it, though.

    DVI and HDMI are pin-compatible. Your right, DVI is more computer-oriented whereas HDMI is more HDTV oriented, but the two use a common signal format. So common, in fact, that HDMI-DVI converters are just dumb devices that wire up pins to the correct spot on the opposite-side connector.

    So yeah, I'm sure the video card knows which one your plugged into, and the software setting difference there makes some sense - because yeah, you assume HDMI = TV whereas DVI=monitor... but as far as why use one and not the other - it really makes no difference (unless you want to carry Audio over the same line).

    And if you get into the higher resolutions, HDMI 1.4 can support higher bandwidth over a single cable, as opposed to DVI having to branch out to dual cables, and then you have a valid and technical case for using HDMI over DVI.

    The real question is - why not DisplayPort?

    Because his monitor doesn't support it.  But yeah, that would be my first choice if everything does support it and you have the cable.

    DSR doesn't force higher resolutions on the monitor. THe video card only renders to a higher resolution, then it gets downsampled and displayed at whatever resolution your monitor is in the first place.

    True, but if your getting a 980, which has 3 DisplayPort outs, one DVI, and one HDMI, why would you get monitors without DisplayPort... which is what I'm really getting at.
    It's one thing if the monitors are older and left over from an older computer. But it doesn't appear so.

    Do you have a TV you can connect to and compare? I have had monitors that have had washed screens before, it's more than likely just the nature of that line of Acer monitor. I took a 20inch and compared it to my 24inch both and the 20 inch was noticeably better, the 20 inch was a cheap samsung, the 24 inch was washed and it bother me so much I just couldn't use it. Right now I'm using an asus 23.5 it looks and performs wonderfully.

    How do the monitors perform with only one connected?

    i also have a issue with HDMI connection to my computer. i recently bought 2 AOC 23" monitors both have DP and HDMI but no DVI. So i thought well ill run one DP and one HDMI. Everythign is good but the colors on my DP are much more vibrant than my HDMI monitor....guess ill just have to spend 500ish on a new video card with 2 DP's

     

    I remember reading somewhere that it has somethign to do with Nvidia cards only....

    So I recently purchased two monitors this week. Both are Acer H236HL 23" Monitors which are IPS with 5ms repsonse rates (GTG). They're great monitors for only 128.00 USD.

    I just spent last night and this afternoon trying to figure out why HDMI by default is so washed out when I looked at it side-by-side with my VGA connected monitor. It seems that the colors are limited so you don't have the full gambit of colors when initially plugging in the cable. 

    I eventually stumbled on this forum post http://hardforum.com/showthread.php?t=1729604 which fixed the issue after running the quick fix and restarting my computer.

    I just wanted to share this with anyone who might have experienced this issue on their monitors.

    Thanks man, that made wonders for the vividness of my triple monitors!!!

    Always thought they looked a bit bleached.

    3x Samsung 27", 2x NVidia GTX 770 GTX SLI.

    I actually fixed the washed out colors by switching from RGB to YCbCr444 in the NVIDIA control panel. Though it's hardly a fix, but simply setting it up properly. RGB is 16-235 after all.

    As I said earlier, one is connected through HDMI and the other is connected through DVI.

    So you connected one monitor using the DVI port, the other using HDMI, the one on DVI worked right out of the box, the one on HDMI looked bad, and having the two right next to each other is why you noticed a problem?  That explains a lot.

    Because I didn't feel the need to spend 200-300 dollars on monitors that'll support 2560+ monitors. These two monitors give a very nice quality for only 129.00 each.

    It's your money... I can't fathom why the top-of-the-line 980 (and rest of the components if I recall a previous thread) but cheaped out on the monitors - I would think if anything going the other way around, because a good monitor will last a lot longer than a video card.

    Although monitors are due for some shaking up soon - 4K is breaking out, OLED has been "around the corner" for a while now, GSync/FreeSync is starting to gain some traction... so I guess if you were just looking for a stop gap while eyeing something along those lines - it makes a bit more sense.

    Otherwise, my opinion aside - good observation in your OP and thank you for posting the fix.

    My opinion only, but I don't consider monitors that don't have 16x10, or displayport. If they make you happy, it's your money, that's all that matters.

    "Better" also depends on what your priorities are. 4k is definitely better than 1080p in the resolution department (although it may be weaker in other areas).

    Don't want to hijack, but it's on topic.  If I have a monitor that supports both DVI and display port, will I see better visual quality with the display port over the DVI?

    Usually not, though this is in the sense that a $100 video card can display the Windows desktop just as well as a $500 video card.  DisplayPort can do more than DVI, but if DVI can do everything you want to do or everything the monitor supports, then there's no way for DisplayPort to improve on that.

    If you're trying to run more than two monitors at a time, run very high resolutions at high frame rates, or want to use the upcoming adaptive sync, then DisplayPort offers advantages--but only if your monitor supports whatever you're looking to do.

    If you happen to have both a DisplayPort cable and a DVI or HDMI cable and your monitor and video card both support both DisplayPort and something else, I'd use DisplayPort on general principle as it's less likely that something will malfunction that way.  But if you're using something else and nothing is breaking, then there's nothing for DisplayPort to fix, so there's no point in "upgrading" to a DisplayPort cable.
