How to increase screen refresh rate (won't go past 60Hz) I have a 17-inch Toshiba laptop with a resolution of 1600x900 and a refresh rate of 60 Hz. However, on some backgrounds, I can clearly see my screen flickering. With the preservation of my eyes in mind, it would be greatly beneficial to know if I can increase this or not. I go here: Quote: Control Panel\Appearance and Personalization\Display\Screen Resolution and click "Advanced Settings". Under "Monitor Settings", the pull-down bar only gives me the option of 60Hz (the "Hide modes that this monitor cannot display" is whited out). Is it possible to increase the refresh rate?
EDIT: I have a generic PnP monitor on Intel HD graphics
EDIT#2: I just noticed the similar threads section at the bottom, and found that LCD monitors are supposed to be 60 Hz. But then how do I reduce the flicker? | My System Specs |

To my knowledge LCD screens shouldn't flicker at all regardless of the refresh rate? They don't refresh, the pixel is either on or off. How old is this laptop? Maybe your back light is failing? Other than that, without being able to see what you see, its hard to comment? | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number Home Built OS Windows 7 Ultimate AMD64 CPU AMD Phenom II X4 980 Black Edition Deneb 3.7GHz Motherboard Asus M4N68T-M V2 µATX Motherboard Memory 8GB 4GBx2 Kingston PC10600 DDR3 1333 Memory Graphics Card BFG NVIDIA Geforce 220GT 1 Gig DDR2 PCIe Sound Card VIA VT1708s High Definition Audio 8-channel Onboard Monitor(s) Displays 2 x 19" I-INC AG191D TFT Flat Panel Screen Resolution 1280x1024 x 2 Keyboard Logitech Internet 600 Mouse Logitech Wireless Trackman Wheel PSU Retail Plus 465 Watt Case Power Up Black ATX Mid-Tower Case Cooling Stock heatsink and fan Hard Drives 500 Gig WesternDigital SATA-300 Drive Internet Speed 80 Mbps Down 30 Mbps Up Antivirus Microsoft Security Essentials Browser Internet Explorer 10 Other Info HP DVD1040e Lightscribe - External USB2 |

The laptop is less than 1 month old. And I don't mean that the flickering is so bad that I can barely see the screen, I guess I may have used the wrong wording in my original post. I just mean that on certain (ie - not all) backgrounds I can see my screen flickering (I can see everything clearly, its just more of a nuisance than anything). It's just that I don't want to cause myself any unnecessary eye strain.
Also, I just searched on youtube for what a screen flicker looks like. Mine is a very minor version of the type that renders one unable to see. I guess the light flickering that I see might just be normal; however, I have never seen it before on my desktop, and its monitor was approximately the same size and proximity from my eyes as my laptop is. | My System Specs | | |

I know on my old 19 inch CRT monitor 60hz would give me a headache, especially with a white background. I now have two 19 inch 1280x1024 LCD's and have never ever seen a flicker. I don't know what to suggest, update your drivers I guess? | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number Home Built OS Windows 7 Ultimate AMD64 CPU AMD Phenom II X4 980 Black Edition Deneb 3.7GHz Motherboard Asus M4N68T-M V2 µATX Motherboard Memory 8GB 4GBx2 Kingston PC10600 DDR3 1333 Memory Graphics Card BFG NVIDIA Geforce 220GT 1 Gig DDR2 PCIe Sound Card VIA VT1708s High Definition Audio 8-channel Onboard Monitor(s) Displays 2 x 19" I-INC AG191D TFT Flat Panel Screen Resolution 1280x1024 x 2 Keyboard Logitech Internet 600 Mouse Logitech Wireless Trackman Wheel PSU Retail Plus 465 Watt Case Power Up Black ATX Mid-Tower Case Cooling Stock heatsink and fan Hard Drives 500 Gig WesternDigital SATA-300 Drive Internet Speed 80 Mbps Down 30 Mbps Up Antivirus Microsoft Security Essentials Browser Internet Explorer 10 Other Info HP DVD1040e Lightscribe - External USB2 |

You're not going to be able to change the refresh rate on that laptop monitor unless it was specifically designed to run at a higher rate, which is most likely not the case as the common refresh rate for LCD monitors (including laptop) is 60Hz Quote: While flicker does not occur on LCD displays, it is still necessary to avoid modifying graphics data except during the retrace phase to prevent tearing from an image that is rendered faster than the display operates (LCDs normally always refresh at 60 frame/s). Refresh rate - Wikipedia, the free encyclopedia
Also...... Quote: TFT screens do not refresh in the same way as a CRT screen does, where the image is redrawn at a certain rate. A TFT monitor will only support refresh rates coming from your graphics card between 60Hz and 75Hz (ignoring modern 120Hz monitors for a moment). Anything outside this will result in a "signal out of range" message or similar. The “recommended” refresh rate for a TFT is 60hz, a value which would be difficult to use on a CRT. The “maximum” refresh rate of a TFT is 75hz, but sometimes if you are using a DVI connection the refresh is capped at 60hz anyway.

If I am reading this correctly you have a laptop and you have connected a PnP monitor to it. Is that correct?
If so then:
Which display is blinking - the laptop or the PnP monitor?
Is the PnP monitor an LCD or a CRT?
Connected by VGA, or HDMI cable?
Does your laptop have a dedicated video chip (ATI or Nvidia) or just the Intel graphics? | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number Home Built - Jan 2013 OS Windows 7 64 Bit Home Premium SP1 CPU i7-3820 Motherboard Asus P9X79-PRO - Bios 3305 Memory GSkill F3-14900CL9Q - 16GB Graphics Card EVGA GeForce GTX660 - Driver 310.90 Sound Card On board Realtek ALC898 Monitor(s) Displays Acer S271HL Screen Resolution 1920 x 1080 Keyboard MS KC-0405 Mouse Intellimouse 5-button PSU Corsair CMPSU-850TX-V2 - 850 watt (by Seasonic) Case Corsair Obsidian 550D Cooling Standard 3 120mm case fans, Cooler Master Hyper 212 EVO Hard Drives #1- Samsung 840 Pro Series

One other possible cause for perceived flicker on a laptop LCD screen is the room lighting, this has been a long term issue in industry with fluorescent tube illumination.
If you have this type of illumination you may find that changing your location will cure it, (a possible reason that you do not see the flicker on the desktop) - the way it is done in industry is to use a special control box on twin tubes that controls the strobing of the tubes to produce a steady light source, but this is of course a major outlay. | My System Specs | | Computer type PC/Desktop System Manufacturer/Model Number Real World Computing (Me + a little help from Acer) OS Windows 7 Ultimate x64 + x86 + Windows 8 x64 CPU AMD Phenom II X6 1035T 2.6 GHz Motherboard Aspire M3400 Memory 4Gb PC10600 DDR3 1333 MHz Graphics Card NVIDIA GeForce 315 512MB Sound Card OnBoard - Realtek High Definition Audio Monitor(s) Displays Philips 32" HDTV, (HDMI) + 26" TV (VGA) Screen Resolution 1920 x 1080 @60Hz + 1360 x 768 @60Hz Keyboard Microsoft Wireless 800 or Stock Acer, (depends where I sit) Mouse Microsoft Wireless 800 or Stock Acer, (depends where I sit) PSU Stock (400W) Case Acer M3400 Cooling Stock Hard Drives 500 GB Seagate ST3500418AS SATA II

I shut off the lights and still saw the flickering, so no dice Quote: If I am reading this correctly you have a laptop and you have connected a PnP monitor to it. Is that correct?

Does your laptop have a dedicated video chip (ATI or Nvidia) or just the Intel graphics? I have one display, which is the laptop. I use Speccy (same maker as CCleaner), which tells me the specs of my computer. It said that I have a "Generic PnP monitor on Intel HD Graphics". No extra monitor, no dedicated video chip.
Also, I tried to update my drivers through intel's website but I kept running into errors with it. I guess I'll just have to live with it | My System Specs | | |
