The Amazing Surround CRT-Equivalent Setup

Vega of HardForum set up an amazing surround CRT-quality setup with three ASUS VG248QE and GeForce Titans’s (plus the LightBoost tweak to eliminate motion blur).

This was made possible via a new method of enabling LightBoost (See comments!).  Although TN panels are not good for portrait usage due to viewing angles, fast panning motions remains as perfectly clear (CRT-quality) as stationary images. The CRT-like “smooth as butter” motion apparently outweighed TN panel deficiencies for some users!

Try that with CRT-sized bezels!

    If you’ve enabled 3D Vision mode on your monitor before in the past (the monitor needs LightBoost to be unlocked by an nVidia graphics card in its lifetime), there’s a new simpler method of enabling LightBoost, and this also works on surround setups:

    How to Easily Enable LightBoost — No INF or REG files!!

    1. Download the ToastyX Custom Resolution Utility
    2. Run CRU.exe
    3. Under “Detailed Resolutions”, click “Add”
    4. Enter the numbers found in this screenshot. (Most important: Make sure Vertical Total is 1149)
    5. If using multiple monitors, repeat on each monitor (you can use the “Copy” button)
    6. Click OK, and then reboot.
    7. LightBoost is automatically enabled when you switch to 1920×1080 at 120Hz

    – It may be helpful to remove the extension block. This forces games to use LightBoost. (remove all other resolutions that are not needed).
    – LightBoost stays persistent.
    – You don’t need to enable Stereoscopic 3D via nVidia Control Panel. Keep that disabled, so you don’t need Control+T.
    – It does not interfere with 3D Vision if you want to use that (just re-enable Stereoscopic 3D)

      No, the LightBoost hardware does not appear to be capable of strobing at 144 Hz. It’s probably because the margin between refreshes is too exceedingly tight for pixel persistence to fit in a vertical blanking interval (required for full-panel strobe backlight operation).

      Fortunately, there’s much less motion blur with LightBoost 120 Hz due to the 1/700th second to 1/400th second strobe backlight flashes (similar to CRT). This has less motion blur than 1/144th second frames being shown continuously for a full refresh (sample-and-hold).

      If you just bought your monitor, and it’s never had 3D Vision enabled before, then you probably need to follow the full LightBoost HOWTO.

    Hey I first tried the full HOWTO with my XL2411T but since bf3 entered 3D-mode every time I tabbed in to the game I quickly grew tired of the lightboost hack.

    Now when I found this guide I uninstalled the previous drivers for the screen (don’t know how to remove the reg-file changes though) and followed this instead. What happends after the reboot is that I only have 120 hz available in nvidia/screen resolutions settings, as well as no lightboost enabled.

    What could be wrong?

    So I just got my vg248qe, and in lightboost mode I have these really bad streaks on my screen. I can also see them at just normal 144hz but not at 85hz and below. Do I have a defect or does this happen at the higher hz for you too? I figured you’d be the guy to ask, with 3 and all! Thanks!

    • Chief Blur Buster says:

      Enable LightBoost at 120Hz and nearly all the streaking will completely disappear. If you want to stick to 144hz though, change “Asus Trace Free” to 60.

      However, LightBoost at 120 Hz has much less motion blur than 144 Hz without LightBoost. Same reason why CRT still has less motion blur than LCD despite CRT phosphor decay (1 to 2ms) now almost equalling modern LCD pixel persistence (1 to 2ms). You gotta do it stroboscopically too (strobe backlight); to also fix the motion blur, and make LCD have motion as clear as CRT. Even CRT 60fps@60Hz often looks sharper than common LCD 120fps@120Hz. LightBoost fixes that problem.

      • alfalfanater says:

        Nah man, thats not what I mean. Not in terms of motion streaking, there’s just a bunch of grey streaks all over my screen from the panel itself. I haven’t seen anyone describe anything like it in reviews or anything so I’m pretty sure it’s a defect. I’ll try taking a picture of it and posting it

    • Chief Blur Buster says:

      Some people have successfully enabled LightBoost by having both a GeForce and a Radeon. You enable it on your GeForce first, then hot-plug your DVI into a Radeon (Radeon pre-configured with ToastyX Custom Resolution Utility, see instructions here). As long as the picture settings on the monitor doesn’t get reset to factory defaults (e.g. blackout, power unplug), it will continue to remember the LightBoost settings.

      However, nVidia would obviously prefer you to buy a GeForce Titan. 🙂

      • Revoltz says:

        I tried this, after hot-plug 7970 monitor still show in osd that lightboost is active, in games “3d” work, ctrl+t disable that, but I dont see difference in speed… I have no idea what I doing wrong
        (sorry for language)

        • Chief Blur Buster says:

          LightBoost doesn’t change the speed of games.
          LightBoost reduces motion blur, (1) during fast motion and (2) when you do framerate matching Hz (or near)

          Example of areas that benefit from eliminating motion blur:
          — Fast 180-degree flick turns in FPS shooting.
          — Shooting while turning, without stopping turning (easier on CRT or LightBoost)
          — Close-up strafing, especially circle strafing
          — Running while looking at the ground (e.g. hunting for tiny objects quickly).
          — Identifying multiple far-away enemies or small targets, while turning fast
          — Playing fast characters such as “Scout” in Team Fortress 2
          — High-speed low passes, such as low helicoptor flybys in Battlefield 3, you aim better.

          LightBoost doesn’t benefit you much if you can only run at 60 frames per second.

    I mean that it still ghosting. “Enable Stereoscopic 3D settings for all displays” is enabled, also in nvidia control panel 3D enabled, but no result.

    • Chief Blur Buster says:

      LightBoost is only officially supported on nVidia graphics cards. Try the ToastyX method instead. Some people have successfully used the hot-plug method provided they changed the 120Hz resolution on the Radeon to a Vertical Total of 1149. So you need to run the same ToastyX Custom Resolution Utility and import the same lightboost.bin file on both systems, before you hotplug.
