why can my monitor only do uhd at 60hz and not 244hz

Recommended Posts

Posted · Original PosterOP

Very simple.. i have a kg251q acer gaming monitor. it'll do 1900x1080 at 244hz.. but NOT AT FHD1080p.  Can anyone simply explain to me why it has to be on 60hz? it's still displaying 1900x1080.. which is uhd.. I'm clueless to as whats going on here that makes it so the same pixels only are true UHD at 60hz. What's the math here. Thanks!

I don't think you know what UHD means.

UHD is 3840x2160p

... What?

You have a 1920x1080, which is FHD/full HD .. It can do 244Hz according to you.. (I only see 75Hz on the Acer site).

UHD or Ultra HD is usually the term used for 3840x2160, which has 4 times the pixels of 1920x1080. So in theory, FHD 240Hz and UHD 60Hz take up the same bandwidth.

 

So uhh.. What are you asking here exactly, i don't really understand your question.

errr FHD full hd. 1080p.

 

What I'm saying is my FHD monitor will do 1080p but only at 60hz.. WHY NOT at 244hz?.. Does it try and bottleneck? It's only promised like this.. https://imgur.com/a/URwbmaJ

Several of the numbers here seem questionable. 244hz? 1900x1080?

 

It's actually pretty simple why at higher resolutions the refresh rate has to decrease. It's all about bandwidth. This can be impacted by the source, the cable, or the display. Any interfaces or items in your video chain can also impact this.

 

It takes the same amount of bandwidth to move 4k @ 60hz over a cable as it does to move 1080p @ 240hz.

This question is the equivalent of "Why can't all cpus be 10 GHz!?!?!".  Simply put, it is not within the spec of the product to do so.

so its 1080 resolution but it cannot. "progressive scan" at 244hz. OOOH, k. im dumb and think i just answered my own question. so its just 1080 at 244hz. you need the progressive scan to make FHD FHD.

Im saying itll let me select 1900x1080 at 1080p only at 60hz. at 244hz it will only allowed me to select 1900x1080.. it loses the ability to "progressive scan" at anything over 60hz. thus losing the title of "full high definition" at anything over 60hz. So i didnt get burnt on the monitor because i only spend 150 bucks. but give me a FHD at 244hz.. im guessing thats a 1000 dollar monitor.

 

Wonder what the output is on a 4k monitor.. ect. thanks!

im guessing a 4k 144hz monitor could do true 1080p at a higher resolution than 60hz but not 244hz yet.

so im guessing you could get a higher output refresh rate out of 1080p from a 1440p display. my guess is a 1440p monitor would do 1080p at something like 80hz. but i dont know. thanks for the help guys.

It's 240Hz not 244Hz, and 1920x1080 not 1900x1080.

 

Also, monitors deliver progressive scan regardless of the "p" or not.  It's how they work.

 

If you're running 1920x1080 @240Hz... you're all good to go.


Edit:  The Acer kg251q is a 75Hz monitor, not a 240Hz.

It can display at 244hz? says so on the front of the box.

 

sorry about the pixel count sorry.

 

i disagree at 244hz its not 1080p it is 1080sd Standard definition.

1080sd isn't a thing that I have ever heard.  480 is standard, 720/1080 is high def.

 

Okay, using Acer's site, it's a 144Hz monitor.  Amazon has is listed as 75Hz for some reason.

Yeah, it's a 240Hz 1080p monitor.  You may have the model number wrong, but it should do 1080 @240Hz.
