December 30, 200520 yr My monitor's max refresh rate is 75hz at 1280 x 1024.However,my X800 Pro keeps running it at 70hz.I've tried using the "force" button within CCC but upon reboot it reverts back to 70hz.Does anyone know why it is doing this and how to fix it.Thanks
January 2, 200620 yr I'm sure i read somewhere that the lower the refresh rate the better..i run mine at 60hz..could me wrong ,but i've never had a problem steve
January 3, 200620 yr Hi kiwimail,Refresh rates on LCDs are different from refresh rates on CRTs. I don't know the technical details but certainly on a practical level, I can immediately tell low refresh rates on CRTs whereas on LCDs, I can't tell the difference (besides high refresh rates leading to a slight dimming of the screen). Like Steve, I remember reading that on LCDs, it is generally advised to keep refresh rates at 60Hz, which sounds horribly low for CRTs but on my LCD, it hasn't been an issue at all.Hope this helps.Edwin
January 3, 200620 yr If you're using an LCD, I agree, keep your refresh at 60Hz. There's nothing to be gained by speeding it up. It's a physical array of pixels that stays lit until another image is put in the display's buffer. Faster refresh on a CRT monitor is desireable, because the phosphor coating on the screen decays in brightness after the electron beam passes through, and a faster scan rate reduces the time each pixel has to decay in brightness, and thus reduces the magnitude of the screen strobing. It's especially noticeable if the scan rate is close to 60Hz and there's fluorescent lighting in the room, which is also strobing at the 60Hz line freq, and which is almost always a tiny bit out of phase with the monitor, accentuating that strobing effect. Good for a real headache after a while.Bottom line, though...there's probably a setting in the device driver for the monitor itself that's responsible for the vid driver defaulting to 60Hz. Be careful about going to great lengths to override that.CheersBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile Bob Scott | President and CEO, AVSIM Inc ATP Gulfstream II-III-IV-V Sys1 (MSFS20+24/XPlane12+11): AMD 9800X3D, water 2x240mm, MSI MPG X670E Carbon, 64GB GSkill 6000/30, nVidia RTX4090FE Alienware AW3821DW 38" 21:9 GSync, 2x4TB Crucial T705 PCIe5 + 2x2TB Samsung 990 SSD, EVGA 1000P2 PSU, 12.9" iPad Pro Thrustmaster TCA Boeing Yoke, TCA Airbus Sidestick, Twin TCA Airbus Throttle quads, PFC Cirrus Pedals, Coolermaster HAF932 case Sys2 (P3Dv5/v4): i9-13900KS, water 2x360mm, ASUS Z790 Hero, 32GB GSkill 7800MHz CAS36, ASUS RTX4090 Samsung 55" JS8500 4K TV@60Hz, 3x 2TB WD SN850X 1x 4TB Crucial P3 M.2 NVME SSD, EVGA 1600T2 PSU Fiber link to Yamaha RX-V467 Home Theater Receiver, Polk/Klipsch 6" bookshelf speakers, Polk 12" subwoofer, 12.9" iPad Pro PFC yoke/throttle quad/pedals with custom Hall sensor retrofit, Thermaltake View 71 case, Stream Deck XL button box Sys3 (DCS/P3Dv4/ATS/ETS): AMD 7800X3D, MSI MPG X870E Carbon, Noctua NH-D15S, 64GB GSkill 6000/30, EVGA RTX3090 Alienware AW3420DW 34" 21:9 GSync, Corsair HX1000i PSU, 4TB Crucial T705 PCIe5 + 2TB Samsung 970Evo Plus, TM TCA Officer Pack, Saitek combat pedals, TM Warthog, TM RS300 FF wheel/pedals, Coolermaster HAF XB case
