(Redirected) Dell 4 k P2815Q refresh rate programs

Hello

I bought the monitor 4 k P2815Q. I know it works on only 30 Hz of refresh rate to 2160 p - which I thought would be good for watching videos (I've tested it is).

But when I put equal or less than 1440 p I can still feel that he runs about 30 Hz, even if I change the settings to 60 Hz - no difference at all, and it feels laggy. I want to run on 60 Hz on a lower resolution.

I use Display port Mini - which is the cause maybe?

My office is performing, so this isn't the cause, with Asus R9 270 x GPU which I doubt is the cause.

How can I fix?

Thank you!

  • refresh rate 9477

    Hello

    I have a 8184-one module 9477 cDAQ chassis to shipwreck. In the specifications is: update rate = 8µs.

    Now my question, does that mean? I have to go out to die in a resolution of 1 ms, but the fastest way is currently approximately 50ms!

    I create a task for a single channel and rocking in a while of loops without delay, calling the .vi DAQmx Write (Bool digital 1Line 1 point). I can't get faster as 50ms.

    The refresh rate of 8µs is relevant only with the use of a cRIO chassis?

    I don't know if your hardware supports hardware timed single output. If this is the case, you will need to program it. Of is not, so you use with your sync 1 point, avoiding the. You would need to use the sample n writing and specify the clock.

  • Slow refresh rate using a D3100 connect two monitors U2311H

    Hello

    I have a macbook pro 2016 and bought the Dell D3100 triple display USB adapter to use with it. The two monitors are connected to DVI using adapters connected to the displayport and hdmi ports. I installed the latest drivers from displaylink for El Capitan on the computer and plugged the dock on USB 3.0. The two monitors work. However, they all seem to have some considerable delay. Testufo indicates that they are both running at 60 Hz (as well as the display settings), but movement seems choppy and fuzzy, akin to 30 hz, but maybe a little better.

    I read that it would be able to run monitors 1080 at 60 Hz with little trouble. Is there something I am doing wrong?

    Thank you

    We didn't test the D3100 on Apple hardware or software is a big unknown.


    The slow refresh rate tells us that they're not really running at 60 Hz.

    The U2311H has the following ports video =.
    DP 1920 x 1080 60 Hz
    DVI 1920 x 1080 60 Hz
    VGA 1920 x 1080 60 Hz

    The D3100's video next ports =.
    Display Port 1.1 = 3840 x 2160 30 Hz, 1920 x 1080 60 Hz
    HDMI 1.4 = 2560 x 1440-50 Hz

    So the U2311H using DP 1. 1 a/DVI should be 60 Hz. The other at 50 Hz. But how the Apple operating system is to see these is unknown. You must post on the Apple Forum of Discussions and see if they can offer an overview or troubleshooting steps.

  • Screen refresh rate

    Just so a while ago I tried to change my screen refresh rate so that a program can open properly because it seems always just for a fraction of a second, then stop again without any error message or anything like that. Then I did the standard thing we do when refresh rate of the screen: the screen resolution-> advanced settings-> monitor-> screen refresh rate. But there was a problem: the only option available is "default material use. Is there a way to get around this? I reinstalled Windows there are hoping to fix freezes - that worked 2 days only, and I'm not quite up-to-date with all the updates/drivers. Maybe that's a problem?

    Thank you

    The driver for your graphics card must contain a 'Custom' option were you can set and test the different resolutions and refresh rates.

    Graphics/video drivers:
    Check the download site of the manufacture of the graphics card for the latest Windows 7 drivers for your card.

  • refresh rate

    Dear Dellers

    I have a Dell ultra - Sharp U2713HM to TAU.

    Why can't I view at a frequency greater than 60 Hz stimuli?

    Thank you very much

  • Refresh rate of Quadro NVS 140 for external monitor

    I absolutely have to change on my external monitor refresh rate. I dropped the laptop this morning and broke the LCD screen, so I plugged an old maryvonne 17F3. I can't change the refresh rate and it flickers badly. Technical support eMachines stated that the refresh rate is controlled by the video card and that no driver is required for their monitor (as they have not first: smileysurprised :).) So how can I change the refresh rate? I have the latest Dell drivers for my 830 latitude.

    Thank you.

    Hello

    I noticed that on some computers laptops Toshiba, the screen refresh rate is fixed on 60 Hz.
    The screen refresh rate is not important on laptop screens.
    Matrix TFT is not such a thing as the refresh rate. It is not blinking.
    TFT as all other LCD screens do not refresh rate setting, only the reaction time.
    Your eyes are sure ;)

    PS: as much as I know AGP port is not available.

  • Refresh rate of the external monitor (closed macbook) reset

    Hello

    Im very new to OS X, I have a macbook air 13 "that I have it plugged into my external monitor acer, when he was in closed mode (clamshell) I changed frequency by accident and now I can't change this back as the ' entry is not displayed. How can I change the refresh rate of the external monitor when the settings show only if the macbook is closed? As I said, I'm new so I am not very confident through many parameters, any help is appreciated.

    If you have previously enabled "Screen sharing" Preferences-> sharing system then you can use another Mac to control this Mac and change it to one that works remotely.

    You could 'open' the Mac to use its built-in screen and then be able to change the settings of the external monitor.

    You can try to reset the setting by following the steps listed here Re: how to restore the display settings

  • Can I connect my MacBook Pro (mid-2012) to the TV 4 K w / a 120 Hz refresh rate?

    Hello!

    I plan on buying a new TV (http://www.vizio.com/m43c1.html) and I was hoping to use to connect my MacBookPro mid-2012 as well. I noticed on the forum and just general Google search, that people were discussing if it would work at 30 Hz or 60 hz - but this TV has a 120 Hz refresh rate. My computer works? And if so, what wiring do I need?

    Uh, did you actually READ the tech specs?

    None of those who accept the entrance faster than 60 Hz. The mentioned number of 120 Hz is an internal refresh rate, not the flow of incoming data.

    But it seems that he would eliminate the flicker of the update of 30 Hz.

    --------

    If you can't use the HDMI, I expect you can get 30 Hz with reliability. If play you with him at length and seriously, maybe 50 Hz. If you also get extremely lucky, maybe 60 Hz.

    But 120? Nope!

    The TV can accept and the Mac won't.

  • Satellite Pro U400-11V: possible to increase the 60 Hz screen refresh rate

    I have a laptop Toshiba Satellite Pro U400-11v.
    I just realized that my screen refresh rate is 60 Hz (resolution 1280 x 800).
    Even I decrease the resolution. It won t be another option 60 Hertz.
    Is it possible to increase it?
    My monitor is indicated under the generic name of the PnP in the system.

    You cannot increase the internal laptop display refresh rate and it of not necessary to go higher, because all the internal laptop screens are running at 60 Hz.
    If you would like to connect an external monitor, you will probably see higher available for the external monitor refresh rates.

  • Is on changing LCD refresh rate?

    Hello

    I have Satellite/Satellite L650D series/Satellite L650D - 123; but on my screen refresh rate of 60 mhz which can be changed in any case at a higher rate, or what I need to change to a lower my screen resolution to make it higher?

    Thank you

    No, it is not editable. The LCD screen is not like the old monitors you used with desktop computers.
    It's a different technology.

    Is there a problem with the LCD?

  • Dynadock can only display 1280 x 1024 at 60 Hz refresh rate

    Hello.

    I just installed my dynadock (VGA).
    I run Vista Home Premium.
    I've set up three screens:

    (1) the laptop;
    (2) VGA monitor connected to the laptop.
    (3) VGA monitor connected to dynadock.

    I downloaded the latest drivers dynadock from Toshiba Web site and installed.
    Everything works until my office two additional monitors...

    ... except that when I put in display the Dynadock to 1280 x 1024 at true color (32 bit), the best refresh rate, it will allow me is 60 Hz.

    The laptop is Toshiba Satellite P205D-S6454.
    The two monitors are two 19 "109P 40
    The display through a SV221DD Starview KVM switch.

    I also downloaded and tried the latest drivers from Displaylink (which seems the graphics card in the Dynadock and has some newer drivers than what is included in the latest Dynadock drivers) with the same results.

    Is this normal, or should it be able to give me better than 60 hz to 1280x1024x32bpp?

    Thank you

    Sean

    Hello

    I checked the specs on this site and it seems like the dynadock is only capable of displaying 1280 x 1024 32 bit 60 Hz max.

  • What refresh rate 5 k iMac to?

    IM currently in the prosses to buy a 27-inch iMac with 5 k with upgrades:

    -4.0 Ghz quad-core Intel core i7, Turbo boost up to 4.2 Ghz

    -32 GB 1867 Mhz DDR3 SDRAM - four 8 Gb

    -Disc of Fusion 2 to

    -AMD Radeon R9 M395X with 4 GB of video memory

    (Im a student animation)

    But there is one problem, I am as a player. And my MacBook Pro late 2011 has surved me well, but it died on me, and it's time for a major upgrade.

    My question is, what turns its refresh rate to? I heard its 60 Hz. Now, I can live with that, but I also need to know if I can connect a monitor to 144 Hz to the Mac itself and not had any problems. The main games IT will run is CSGO and TF2 for reference.

    See you soon

    DO NOT buy the computer with 32 GB of RAM, buy it with the 8 GB and 16 GB of Crucial purchase basis or OWC to get to 24GB which will be more than enough!

    I'm sure you can find the refresh rate by searching the tecniques or if you don't know, then call Apple online store and request.
