Although the AVS forum is chock-a-block with X1 postings, there has been very little discussion of the X1 over here, so I thought a brief review might not go amiss. I hope it will encourage postings from other X1 users. Selection: I bought an InFocus X1 clone (IBM ilv300) from Nexnix/Shootandshow about 2 months ago after a demo in comparison with a Z1 and a HT1000. We had viewed some digital TV and DVD on an InFocus LP130 DLP (borrowed from work). We thought DLP picture quality was promising and we hadn't seen any rainbows on it. I was also influenced by reports about degradation of LCD picture over time. So I was looking for a DLP solution and had studied the X1 faq and the many postings about X1 at the AVS forums. In the demo, the 'filmic' quality of the X1 picture was impressive and neither my wife nor I saw any rainbows. We were bothered by the Z1's screendoor and thought the colours too 'primary'. The HT1000 did look better than the X1 in the demo, but not 200%+ better suggested by its price. For our intended level of use (5-6 hours/week) we could not justify a price much higher than £1k. Installation: Screen: 1.8m wide white blackout material roller blind £65 from B & Q. We project onto the 'fabric' side. PJ position: initially on a table, but now mounted on ceiling at approx. 3.8m from screen Viewing position: underneath the PJ. Sources: Digital TV: Nokia Freeview box via ProV de-interlacer to VGA input DVD: Denon ADV1000 all-in-one home cinema receiver (non-progressive) direct to S-video input Cables: VGA & S-Video, each 15 metres, concealed behind skirting boards. Filter: Cokin 62 mm circular polarising filter (see 'Rainbows' explanation below) Aspect ratio: we use the 4:3 setting all the time. This gives satisfactory picture resolution and smoothness from all sources. Picture settings: Picture settings (X1 firmware is v3.8): for TV (via VGA): video mode, contrast 71, brightness 35, color temp. cool, Red 60, Green 50, Blue 50 for DVD (via s-video) : film mode, contrast 85, brightness 50, color temp. warm, Red 50, Green 50, Blue 50 In my experience, it takes several weeks to understand and get the best balance of picture settings on any new display device and the X1 is no exception. These above are the settings that I'm currently using after considerable experimentation. I did attempt to calibrate the DVD input with an Avia DVD, but I didn't much like their very low contrast and high brightness recommendations and have reverted to something more contrasty. However, I've only had the Avia disk for a week and haven't devoted much time to it yet, the picture may still benefit from additional calibration and/or tweeks. Minor installation issues: - it is essential to have a conveniently-placed switch for the power to the PJ because the remote 'off' leaves the fan running at a whisper. - if you have another device connected to the same source as the X1 via a VGA cable (I have an LCD monitor for use when the PJ is off), it is essential to install a VGA switch to select between the output devices because the PJ interferes with the picture when it is powered down. I use a cheap manual 2-way VGA switch for this. - Over-expenditure on cables seems to be inevitable - I have bought a variety of s-video, composite and VGA cables that are no longer in use due to changes in configuration, wrong length of cable, etc. - the only drawback of the IBM ilv300 X1 clone (and the only difference that I have discovered) is that the PJ housing is black (versus the light silver of the standard X1) which makes it very conspicuous on the white ceiling of our living room. I have made a housing from aluminium sheet to reduce this problem. Experience: I think the X1 is a very good choice for viewing PAL material from Freeview TV and from DVD. First impressions were very positive, especially with the TV input. I had some problems getting the DVD to look good via the long s-video cable - it was too dark. This problem was traced to the use of an s-video splitter to feed the DVD signal to a separate LCD monitor. Have removed the splitter and now get a brighter picture, but I suspect that the 15m s-video cable is still attenuating (darkening) the picture a little. This is compensated by an increase in the X1 contrast setting the DVD picture is now very satisfactory. DVD picture fed to the PJ via s-video cable is far superior to the picture obtained when the same signal is routed through the ProV and a VGA cable. I suspect this is down to the ProV and I intend to test the DVD picture from a laptop computer feeding the VGA input very soon. On the other hand, the ProV produces a very respectable digital TV signal via the VGA input. Rainbows: As soon as I started watching DVDs through the s-video input I began to see some rainbows, initially they somewhat annoying. The annoyance has reduced with time and problem it is now almost totally eliminated by the use of a polarising filter. We are currently viewing everything with the polarising filter in place and even with it in place the picture brightness is fine. Noise: With the PJ mounted about 1.5m above our heads, it is not at all objectionable. The bottom line: After two months of tweeking and installation sorting, I'm very happy with the choice of an X1. I never had serious doubts, but there were frustrating moments over the choice of cabling and getting the picture settings right. We are now very happy with the X1's picture quality; the general experience of viewing of DVDs and suitable TV material on the large screen is very positive.
