ASUS PA246Q - Input Lag and Power Use

There is no overdrive or game mode on the PA246Q, as it is targeted at graphics and design with gaming as something you might do in your spare time. Despite that, it does reasonably well with just over a frame of lag from our measurements. There is a 10ms input delay for processing the image, and then 24ms of rise and fall time for the pixels themselves, leaving to a total lag of 22ms. Your effective lag is probably right around 16-17ms, so a single frame. It isn’t the fastest gaming monitor out there, but it isn’t bad either.

Processing Lag Comparison (By FPS)

With its CCFL backlighting system, the PA246Q is not a power efficient display. At minimum brightness it uses more power than the 27” HP ZR2740w and uses just slightly less at maximum brightness despite having maximum light output that is only 65% of that in the HP. Of course it does have a much larger gamut enabled by the CCFL backlighting system, but it does take a lot more power to do so.

    just saying!

    Heh, yeah I agree. One of the reasons I still have a 5 year old NEC is because everything else 24" <$300 is 1920x1080.

    I need that extra screen real-estate, 120 pixels is an entire row of icons.

    You can find the Dell U2412M for less than $300. It is e-IPS, which has compromises but is pretty decent.

    I use the U2412M and I love it, despite the compromises one must take for eIPS--mind you, I'm not a photographer and I actually play a lot of games, but the input lag is low and it doesn't ever feel "slow." The viewing angles are fantastic, great for when folks cluster around the PC to watch videos. :)

    Agreed. I'm also mainly a hardcore gamer, but I do a little photo editing too. And you just can't beat the U2412M for the price. With a little calibration, it's really that good. It's not as good as a "real" IPS nor a TN panel. But it retains like 80% of the qualities of both systems!

    +1 for 16:10 --voted with my wallet

    You have the min/max backwards for some of the monitors in the graphs.

    BenQ VW2420
    Asus PA246Q
    NEC PA271W
    NEC PA301W
    DoubleSight DS-277W

    Are all backwards, and because of this it's causing the sorting on the graph to be a bit off.

    Fixed. Probably just an error in the data in Chris' spreadsheet.

    Jared, can you weigh thing without the stand attached. Might seem a strange request but I use a 2 monitor arm that uses VESA mounts but the system has a weight and size limit. I purchased 22 inch originally to stay under the weight limit (and I'm looking for a better monitor for the main monitor) but ASUS doesn't seem to care to tell anyone what the monitor weighs without the stand as I've looked everywhere.

    You guys know this has been replaced by the PA248Q at a much lower price of $339.
