Does hdmi 1.4 or vga support 120htz

[gabrielvis8]

i have a msi ge70 2pe apche pro wiht a gtx 860m and i know it cant run most games at even 30 fps but i mostly play cs and overwatch which i get 100 fps on low setting i wanted to know can my laptop support 120 htz i only have an hdmi and vga port and want to get a gaming monitor i do have a hpvs 17 which gives me 75 htz it is at a lower resolution but i dont care i use this monitor now more than my laptop's 1080 60 htz monitor i know im crazy ill stop rambling. So can i support 120 htz because if i can ill get a gaming monitor for my laptop and ps since my tv sucks : ( and makes game on ps4 so ugly its a samsung ln46d503f6fxza its discountined but i want to know if it truly sucks or my eyes are messed up or pc master is too good  k ill stop rambling ok  answer me k

if the resolution is lower than 1080p probably idk how much lower it has to be.

VGA can only support 120hz at 640x480, but don't quote me on that.

HDMI can do 2160@60, 1440@144, and 1080@144. Don't ask me about revisions though.

VGA is analogue and supports high refresh rates. How high, it depends on the RAMDAC of the video card..

In a simplified way ... the refresh rate x resolution = bandwidth and the RAMDAC (digital to analogue converter on the video card) has a limited bandwidth so the higher the resolution you choose to output on your VGA connector, the smaller the refresh rate is.

So while you may be able to output a maximum of 2048x1536 or something like that on the VGA connector but at 60 Hz, you may be able to do 1280x1024 or even 1600x1200 (4:3 aspect ratio) at 100-120 Hz and with smaller resolutions like 800x600 you may even be able to have 180-240 Hz.

 

However, these high refresh rates can only be useful with old style CRT monitors (those big heavy things). A 14" CRT monitor will do 1024x768 at 85 Hz (which really should be the minimum refresh rate otherwise your eyes will be hurting, as CRT monitors work differently than LCD monitors). A high end 21" CRT monitor may be able to do close to 1080p at 85 Hz and higher refresh rates at lower resolutions, for example a Sony G520 from 2002 can do 105 Hz at 1600x1200 

 

LCD monitors have circuitry inside that takes analogue signal coming from the video card in the vga connector and converts it back to digital to be processed and converted in whatever format is required by the lcd panel to show it on the screen.  While the circuitry supports (tolerates) a wide range of refresh rates (the reason why you see sometimes on LCD monitors stuff like 50..75 Hz or sometimes even more), the huge majority do it just for compatibility reasons with old devices, and in reality whatever is coming is converted into a fixed number of 60 digital pictures a second.  So even you configure the refresh rate to 75 Hz and connect a lcd monitor through VGA, the image on the lcd screen will only be updated 60 times a second.

 

There are some new monitors out there which are designed to be able to update the LCD panel more than 60 times a second, but most require DisplayPort or DVI which your video card probably doesn't support.

There's also some monitors which support up to 75 Hz (75 updates a second) using FreeSync over HDMI but your video card is probably too old to support it (and nVidia has their own competing Gsync so that would also be a reason why such monitors would only work at 60 Hz)

 

HDMI supports various resolutions and refresh rates, depending on the HDMI version the card has. Such an old card probably has the most common hdmi version (1.3) which can do a maximum of 1920x1200 at 60 Hz. At 1280x720 it may do 100-120hz but the lcd display has to support it.

oh well i have hdmi 1.4 need to know if that supports it or they wont be a point of getting a 144 hetz monitor

well i do have a hp vs17 which gives me 1280 * 1024 75 htz

hdmi 1.4 supports up to 1920x1080 @ 120 hz

You should check that the video card can also do that.

You should. As long as your CPU and GPU can hit the marks.
