  • Do a search for you server OS + STIG

    Then, for each service you’re hosting on that server, do a search for:

    Service/Program name + STIG/Benchmark

    There’s tons of work already done by the vendors in conjunction with the DoD (and CIS) to create lists of potential vulnerable settings that can be corrected before deploying the server.

    Along with this, you can usually find scripts and/or Ansible playbooks that will do most of the hardening for you. Though it’s a good Idea to understand what you do and do not need done.




  • I would check two things:

    1. Is it a QLED tv? Those are very efficient with the backlight power. QLED only have a blue led backlight and the “quantum dots” in the panel between the backlight and the LCD panel absorb the blue light and emit the red green and blue needed to create the full color spectrum.

    2. How many nits of brightness does it produce? I’d check for the specific model on RTINGS. It won’t help OP much if the TV is efficient, but so dim that it’s unusable in their case.

    Reflectivity also helps with brightness when viewed in a bright room. The less reflective (matte) the less brightness the TV needs to overcome distracting light sources reflecting on the screen.

    Edit: Had to look it up to be sure, normal LED panels use filters that filter red, green, and blue light from a white light source. This means roughly 1/3 of the light from the backlight is filtered away, hence the energy inefficiency vs QLED which uses the energy from the blue light to create the colors.

    Intestingly, some DLP projectors use alternating red, green, and blue light sources which strobe on the DLP chip which takes turns modulating the intensity of each color. Less efficient (and bright) DLPs use a single white light source and a color wheel (rotating color filter).
















  • Frametimes is the specific measure.

    <11.1ms for 90Hz or <8.33ms for 120Hz

    If the game, experience, or whatever breaches that minimum frame time frequently, then you can experience nausea just from moving your head around.

    It does require some sacrifices like turning shadows down a notch or two in some game engines and choosing additional visual effects carefully. Some visual effects require additional computation passes and can add the the frame time.

    A low latency CPU (like the AMD 3D cache CPUs) or a normal mid to high end CPU with fast memory with good timings helps quite a bit.

    The GPU should be capable of pushing the pixels and shading for the target resolution. Even with a 6900xt I’ve been able to comfortably push over 4500x3000 per eye rendering (enough to get a nice anti-aliasimg effect on my Pimax 8kX at the “normal” 150 degree H.FoV) in most games.

    Surprisingly, fidelity FX can help as well (the non-temporal version).
