I got a good deal on a new ViewSonic monitor recently (
http://www.viewsonic.com/products/lcddisplays/xseries/vx2435wm/ ), and have been testing out devices hooked up to all of the inputs. For the most part, it's all pretty brilliant, but I'm having some weirdness going through the HDMI.
Since it only has one (no DVI, which I find a strange exclusion), I picked up a MonoPrice switchbox (the HDS-201) to be able to plug in other HDMI devices, and with my PC it works flawlessly in every mode and resolution I can test. I'd like to keep it in 1:1 pulldown, so there's no chance of it warping or stretching different aspect ratios and such, upscaling on more of a case-by-case basis.
Testing the PS3, however (to see what it would be like) produces an odd result. While it tells me it's outputting at 1080p, 1:1 pulldown shows it as more... 1750x1000, or something strange like that. (I'm guesstimating the area compared to my PC's 1680x1050.) If I switch to a 4:3 aspect ratio it properly shifts to a 1920x1080 resolution, but for whatever reason designated 1080p content (games, videos, and system menu) only goes to somewhere in that 1750x1000 range and considers it "full screen." Playback of a DVD without upscaling (so, 480p) and "double size" work just fine.
So... does anyone know if this is a quick of HDMI playthrough in general or with the switchbox? My testing with the PC leads me to believe it's more on the PS3's end, but I have no idea just what might be causing it. It seems like an odd thing since it's basically ONLY that mode on 1:1 pulldown that acts like that.
I suppose I could switch to 4:3 and deal with it, but I'd rather not deal with potential other issues on PC-side with games (my primary use) or auto-upscaling 720p content (as I assume it would), so would rather try to figure out what's going on with 1:1 first and fix it, if I can.
