Timespotter :
Hello Kyle,
have you mamaged to solve the 1 inch gap problem? I also have the Acer H233H with ATI Radeon HD4670 connected via HDMI. 1680x1050 fills the screen but it does not look good, I'd definitely prefer the native 1920x1080 resolution (refresh rate 60 Hz does not help at all).
Thanks for your advice,
Martin
Hey Martin,
In a way I sort of did and sort of did not. To tell you the truth I don't know all the details, but I'll share what I know.
Possibility #1:
It turns out HDMI has some kind of proprietary design to it, it must have a patent or something, and a company cannot fully integrate HDMI into their device without paying the HDMI founders group some licensing fee. It turns out ACER did not pay this licensing fee for the H233H monitor and therefore HDMI is weird. If this seems strange I totally agree. Why bother even adding an HDMI port if it is not going to work? It has been a few months and my memory is fuzzy, but I remember spending time with ACER support (a few hours on the phone I think, because I can't find an email record) and they either backed this up or gave no better answer.
Possibility #2
This is all the video card's fault. The wikipedia article on HDMI mentions something about HDCP licensing, which might be what I am referring to above. Further, we might have bought a card that supports the wrong HDMI version (or the monitor supports the wrong version! I quote the same wikipedia article,
"In September 2009, AMD announced the ATI Radeon HD 5000 series video cards which features support for HDMI 1.3 output (Deep Color, xvYCC wide gamut support, and high bit rate audio), support for 8-channel LPCM over HDMI, and an integrated HD audio controller with a Protected Audio Path that allows bitstream output over HDMI for AAC, Dolby AC-3, Dolby TrueHD, and DTS Master Audio formats.[138][139][140] The ATI Radeon HD 5870 released in September 2009 is the first video card that supports bitstream output over HDMI for Dolby TrueHD and DTS-HD Master Audio." So maybe the 4870, unlike the newer bad to the bone 5870, is missing this very upgrade...
So Martin, Ultimately what I did was stop using HDMI and switch over to the DVI connection. The DVI connection works perfectly. I liked HDMI, because it included audio. I had to run audio separately to the monitor when I switched to DVI.
If you bought the same video card and monitor you should have this option (I hope). HDMI would have been sexier, but I gave up on it after the hours kept disappearing into the HDMI incompatibility abyss.
In conclusion, I recommend switching to DVI.
I hope this helps,
Kyle
P.S. If you have the wherewithal I would suggest an experiment to at least isolate the source(s) of the problem. I could not do this, because all I own is my PC and monitor. If you have a blu-ray player or some game machine with HDMI out, see if the monitor properly displays its contents. On the flip side, if you have an HDTV with HDMI in, see if your PC properly displays its output on the TV.
Four possibilities could occur. If one works and the other doesn't, then at least you know where the problem is coming from. If both don't work (I'd be surprised for some reason) that would really be lame and the findings inconclusive. If both work that is awesome, but this would only deepen the mystery as to why the monitor and PC aren't compatible on HDMI. If you do this please post back. Goodluck.
