Relationship between monitor resolution and max resolution of video card?

espionagelfe 626 245 January 28, 2016 at 07:39 AM
I bought a Dell U3415W monitor with 3,440 x 1,440 resolution. I used it with my stock, low end but newer slim profile desktop and it worked fine. However, I figured my stock video card probably did not do a resolution of 3,440 x 1,440 so I installed an AMD R5 240 video card which apparently has a maximum resolution of 4096 x 2160 pixels. This also had displayport output so I figured it would make my monitor look much better.

However, there was no noticeable difference in picture clarity with the upgraded video card. I noticed the mouse pointer did not lag as much, but what gives? What is the relationship between a high resolution monitor and a high resolution video card. I don’t play video games if that helps, I do a lot of typing so I thought it might make the letters clearer. I’m not a techie by any means.

A digital connection is a digital connection. So if the connection is capable of the resolution and your not using any of the other side benefits of the connection such as Sound in HDMI or daisy chaining in Display port then it doesn't matter. One won't be more clear than the other since they are both digital. Not sure what you were using before in terms of GPU or connections so that is about all I can say without having more details.

If your having clarity problems make sure the monitor is running at it's native resolution and the prefered refresh rate. Make sure clear type is turned on as well.

If you don't notice any difference with the new card, then there are two possibilities:
1) You were already, and remain, running at 3440x1440. So the picture is exactly the same as before. You said you "figured" your card couldn't run that resolution. Resolution is a setting in windows, so you should be able to check and see what it was set to.

2) You were previously, and remain, running at a lower-than-optimal resolution and need to change your settings now to take full advantage of your monitor.

Are you actually seeing any picture quality problems? If your monitor is running at its native resolution there's really nothing you can do for normal apps to make them look different. The newer graphics card might make gaming graphics faster and "better" but it won't change the way normal text in MS Word looks.

You most likely wont notice a difference unless using graphics intensive programs. Do what these guys say and make sure your set at the right resolution and have your drivers updated to the newest version available. Since your complaining that your letters aren't clear, I would expect this to be a resolution issue as that monitor is probably crystal clear at native resolution.

Did you install the drivers for your new card? Graphics card aren't plug-n-play. Its possible that your computer couldn't display the resolution previously, and your card isn't working correctly because of a driver issue. Check out device manager/ display adapters and look for your card.

Either way, Its definitely a good idea you got a card for such a high res monitor. Id say it worth the money, you'll notice when you watch a movie or something.

the same relationship as max speed of your car and posted speed limit.
your monitor - is posted speed limit.
if your car can run at posted speed limit your are fine.

for detailed answer, we need to know hardware info

simply check current resolution on your computer, if card does not support 3,440 x 1,440 you can not select from the list.

low-end/integrated graphics aren't really lacking in resolution (older ones, sure - but then so would older dedicated cards)
