Does HDMI require more processing power than DVI?

by on July 19, 2011

Q: Im thinking about buying a new screen to my computer. I have a 22″ now but are thinking about a 27″. Im a gamer so its important that i dont get alot of “lag”.
Im think about switching from DVI to a HDMI so my question is. How much more does HDMI require from the computer. As it is now i can play all the new games att very high spec at 1680*1050.

    Does your computer or video card have an HDMI port for it? If so you should have no problems taking advantage of it and there being lag.

    Or are you thinking of using a DVI to HDMI cable? Again there should no lag on your system. But they may be incompatibilities in the monitor going from DVI to HDMI (from my experience I am speaking)

    For a while I had my PC hooked up to my HDTV with a DVI to HDMI and had no problems at all. But you may not necessarily get better resolution if the max your PC can handle is 1680*1050.


    My videocard has a HDMI port and im going to use a HDMI cable.

    And beacuse my videocard has a HDMI port it should be able to give me a better resolution than 1680*1050, right?

    Picked as best answer

    You should see any performance difference between HDMI and DVI. You also shouldn’t have any issues since you’d be doing HDMI out from the video card and straight into HDMI in on your shiny new monitor.

    As far as PC gaming is concerned this is basically no difference between using DVI and HDMI as your going between your video card and monitor. So using one or the other doesn’t change what resolutions you’re able to run your screen at.

    In case you weren’t aware the numbers in a resolution refer to the number of pixels(individual dots of color) being displayed. So your current screen has 1,680 pixels left to right, and 1,080 pixels going up and down.

    The ability to run games at higher resolutions really just depends on two things, the native resolution of your monitor and the overall performance of your computer.

    As you shop for new monitors you’ll see a ‘Native Resolution’ listed in the specs. Your current monitor probably has a native resolution of 1680*1050. This is both the highest possible resolution this screen can display and also the one where images and games will look their best. It is the resolution the LCD screen was designed to run at.

    So if you buy a new monitor with a higher native resolution, you’ll be able to run games at this higher resolution, however higher resolution means more processing power and a higher load on the computer. In short, running the same game at a higher resolution will lower your frames per second. So you might need to upgrade your video card to get back up to an acceptable level, or you might already be rocking such serious hardware that your just fine running at a higher resolution.

    Hope that helped out!


    Thanks, it explained alot. I have a Radeon HD 5750 1GB so it isnt the “top of line” card but i get a 6,7 rating in Windows 7 so i hope it will do.
